The ARM Cortex-M3 is a next generation core that offers better performance than the ARM7 at the same clock rate and other system enhancements such as modernized debug features and a higher level of support block integration. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and has a Harvard architecture with separate local instruction and data buses, as well as a third bus with slightly lower performance for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branches. The LPC178x/7x adds a specialized flash memory accelerator to accomplish optimal performance when executing code from flash. The LPC178x/7x operates at up to 120 MHz CPU frequency. The peripheral complement of the LPC178x/7x includes up to 512 kB of flash program memory, up to 96 kB of SRAM data memory, up to 4032 byte of EEPROM data memory, External Memory Controller (EMC), LCD (LPC178x only), Ethernet, USB Device/Host/OTG, a General Purpose DMA controller, five UARTs, three SSP controllers, three I2C-bus interfaces, a Quadrature Encoder Interface, four general purpose timers, two general purpose PWMs with six outputs each and one motor control PWM, an ultra-low power RTC with separate battery supply and event recorder, a windowed watchdog timer, a CRC calculation engine, up to 165 general purpose I/O pins, and more. The analog peripherals include one eight-channel 12-bit ADC and a 10-bit DAC. The pinout of LPC178x/7x is intended to allow pin function compatibility with the LPC24xx and LPC23xx.

Functional description 7.1 Architectural overview The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and the D-code bus. The I-code and D-code core buses are faster than the system bus and are used similarly to Tightly Coupled Memory (TCM) interfaces: one bus dedicated for instruction fetch (I-code) and one bus for data access (D-code). The use of two core buses allows for simultaneous operations if concurrent operations target different devices.

All rights reserved. 40 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller The LPC178x/7x use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and other bus masters to peripherals in a flexible manner that optimizes performance by allowing peripherals that are on different slaves ports of the matrix to be accessed simultaneously by different bus masters. 7.2 ARM Cortex-M3 processor The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high performance and very low power consumption. The ARM Cortex-M3 offers many new features, including a Thumb-2 instruction set, low interrupt latency, hardware division, hardware single-cycle multiply, interruptable/continuable multiple load and store instructions, automatic state save and restore for interrupts, tightly integrated interrupt controller with wake-up interrupt controller, and multiple core buses capable of simultaneous accesses. Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. Typically, while one instruction is being executed, its successor is being decoded, and a third instruction is being fetched from memory. The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical Reference Manual that can be found on official ARM website. 7.3 On-chip flash program memory The LPC178x/7x contain up to 512 kB of on-chip flash program memory. A new two-port flash accelerator maximizes performance for use with the two fast AHB-Lite buses. 7.4 EEPROM The LPC178x/7x contains up to 4032 byte of on-chip byte-erasable and byte-programmable EEPROM data memory. 7.5 On-chip SRAM The LPC178x/7x contain a total of up to 96 kB on-chip static RAM data memory. This includes the main 64 kB SRAM, accessible by the CPU and DMA controller on a higher-speed bus, and up to two additional 16 kB each SRAM blocks situated on a separate slave port on the AHB multilayer matrix. This architecture allows CPU and DMA accesses to be spread over three separate RAMs that can be accessed simultaneously. 7.6 Memory Protection Unit (MPU) The LPC178x/7x have a Memory Protection Unit (MPU) which can be used to improve the reliability of an embedded system by protecting critical data within the user application. The MPU allows separating processing tasks by disallowing access to each other's data, disabling access to memory regions, allowing memory regions to be defined as read-only and detecting unexpected memory accesses that could potentially break the system.

All rights reserved. 41 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller The MPU separates the memory into distinct regions and implements protection by preventing disallowed accesses. The MPU supports up to eight regions each of which can be divided into eight subregions. Accesses to memory locations that are not defined in the MPU regions, or not permitted by the region setting, will cause the Memory Management Fault exception to take place. 7.7 Memory map Table 6.

The LPC178x/7x incorporate several distinct memory regions, shown in the following figures. Figure 6 shows the overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports address remapping. The AHB peripheral area is 2 MB in size, and is divided to allow for up to 128 peripherals. The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals. Each peripheral of either type is allocated 16 kB of space. This allows simplifying the address decoding for each peripheral. LPC178X_7X Product data sheet All information provided in this document is subject to legal disclaimers.

The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial Clock Line (SCL) and a Serial Data Line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the capability to both receive and send information (such as memory).

The I2S-bus provides a standard communication interface for digital audio applications. The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line, and one word select signal. The basic I2S connection has one master, which is always the master, and one slave.

The Controller Area Network (CAN) is a serial communications protocol which efficiently supports distributed real-time control with a very high level of security. Its domain of application ranges from high-speed networks to low cost multiplex wiring. The CAN block is intended to support multiple CAN buses simultaneously, allowing the device to be used as a gateway, switch, or router between two of CAN buses in industrial or automotive applications. Each CAN controller has a register structure similar to the NXP SJA1000 and the PeliCAN Library block, but the 8-bit registers of those devices have been combined in 32-bit words to allow simultaneous access in the ARM environment. The main operational difference is that the recognition of received Identifiers, known in CAN terminology as Acceptance Filtering, has been removed from the CAN controllers and centralized in a global Acceptance Filter. 7.24.1 Features • • • • LPC178X_7X Product data sheet Two CAN controllers and buses.

The timer/counter is designed to count cycles of the system derived clock or an externally-supplied clock. It can optionally generate interrupts, generate timed DMA requests, or perform other actions at specified timer values, based on four match registers. Each timer/counter also includes two capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. 7.25.1 Features • A 32-bit timer/counter with a programmable 32-bit prescaler. • Counter or timer operation. • Two 32-bit capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event may also generate an interrupt. • Four 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Up to four external outputs corresponding to match registers, with the following capabilities: – Set LOW on match. – Set HIGH on match. – Toggle on match. – Do nothing on match. • Up to two match registers can be used to generate timed DMA requests. 7.26 Pulse Width Modulator (PWM) The LPC178x/7x contain two standard PWMs. The PWM is based on the standard Timer block and inherits all of its features, although only the PWM function is pinned out on the LPC178x/7x. The Timer is designed to count cycles of the system derived clock and optionally switch pins, generate interrupts or perform other actions when specified timer values occur, based on seven match registers. The PWM function is in addition to these features, and is based on match register events. The ability to separately control rising and falling edge locations allows the PWM to be used for more applications. For instance, multi-phase motor control typically requires three non-overlapping PWM outputs with individual control of all three pulse widths and positions.

All rights reserved. 56 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller Two match registers can be used to provide a single edge controlled PWM output. One match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon match. The other match register controls the PWM edge position. Additional single edge controlled PWM outputs require only one match register each, since the repetition rate is the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs. Three match registers can be used to provide a PWM output with both edges controlled. Again, the PWMMR0 match register controls the PWM cycle rate. The other match registers control the two PWM edge positions. Additional double edge controlled PWM outputs require only two match registers each, since the repetition rate is the same for all PWM outputs. With double edge controlled PWM outputs, specific match registers control the rising and falling edge of the output. This allows both positive going PWM pulses (when the rising edge occurs prior to the falling edge), and negative going PWM pulses (when the falling edge occurs prior to the rising edge). 7.26.1 Features • LPC178x/7x has two PWM blocks with Counter or Timer operation (may use the peripheral clock or one of the capture inputs as the clock source). • Seven match registers allow up to 6 single edge controlled or 3 double edge controlled PWM outputs, or a mix of both types. The match registers also allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Supports single edge controlled and/or double edge controlled PWM outputs. Single edge controlled PWM outputs all go high at the beginning of each cycle unless the output is a constant low. Double edge controlled PWM outputs can have either edge occur at any position within a cycle. This allows for both positive going and negative going pulses. • Pulse period and width can be any number of timer counts. This allows complete flexibility in the trade-off between resolution and repetition rate. All PWM outputs will occur at the same repetition rate. • Double edge controlled PWM outputs can be programmed to be either positive going or negative going pulses. • Match register updates are synchronized with pulse outputs to prevent generation of erroneous pulses. Software must ‘release’ new match values before they can become effective. • May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler if the PWM mode is not enabled. 7.27 Motor control PWM The LPC178x/7x contain one motor control PWM. The motor control PWM is a specialized PWM supporting 3-phase motors and other combinations.

By monitoring both the number of pulses and the relative phase of the two signals, the user can track the position, direction of rotation, and velocity. In addition, a third channel, or index signal, can be used to reset the position counter. The quadrature encoder interface decodes the digital pulses from a quadrature encoder wheel to integrate position over time and determine direction of rotation. In addition, the QEI can capture the velocity of the encoder wheel. 7.28.1 Features • • • • • • • • • • Tracks encoder position. Increments/decrements depending on direction.

Selectable time period from (Tcy(WDCLK)  256  4) to (Tcy(WDCLK)  224  4) in multiples of Tcy(WDCLK)  4. • The Watchdog Clock (WDCLK) source is a dedicated watchdog oscillator, which is always running if the watchdog timer is enabled. 7.31 RTC and backup registers The RTC is a set of counters for measuring time when system power is on, and optionally when it is off. The RTC on the LPC178x/7x is designed to have very low power consumption. The RTC will typically run from the main chip power supply conserving battery power while the rest of the device is powered up. When operating from a battery, the RTC will continue working down to 2.1 V. Battery power can be provided from a standard 3 V lithium button cell. An ultra-low power 32 kHz oscillator provides a 1 Hz clock to the time counting portion of the RTC, moving most of the power consumption out of the time counting function. The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way that will provide less than 1 second per day error when operated at a constant voltage and temperature. The RTC contains a small set of backup registers (20 bytes) for holding data while the main part of the LPC178x/7x is powered off. The RTC includes an alarm function that can wake up the LPC178x/7x from all reduced power modes with a time resolution of 1 s. 7.31.1 Features • Measures the passage of time to maintain a calendar and clock. • Ultra low power design to support battery powered systems. • Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and Day of Year.

Periodic interrupts can be generated from increments of any field of the time registers. Backup registers (20 bytes) powered by VBAT. RTC power supply is isolated from the rest of the chip. 7.32 Event monitor/recorder The event monitor/recorder allows recording of tampering events in sealed product enclosures. Sensors report any attempt to open the enclosure, or to tamper with the device in any other way. The event monitor/recorder stores records of such events when the device is powered only by the backup battery. 7.32.1 Features • Supports three digital event inputs in the VBAT power domain. • An event is defined as a level change at the digital event inputs. • For each event channel, two timestamps mark the first and the last occurrence of an event. Each channel also has a dedicated counter tracking the total number of events. Timestamp values are taken from the RTC. • Runs in VBAT power domain, independent of system power supply. The event/recorder/monitor can therefore operate in Deep power-down mode. • • • • Very low power consumption. Interrupt available if system is running. A qualified event can be used as a wake-up trigger. State of event interrupts accessible by software through GPIO. 7.33 Clocking and power control 7.33.1 Crystal oscillators The LPC178x/7x include four independent oscillators. These are the main oscillator, the IRC oscillator, the watchdog oscillator, and the RTC oscillator. Following reset, the LPC178x/7x will operate from the Internal RC oscillator until switched by software. This allows systems to operate without any external crystal and the boot loader code to operate at a known frequency. See Figure 7 for an overview of the LPC178x/7x clock generation.

The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1 % accuracy over the entire voltage and temperature range. Upon power-up or any chip reset, the LPC178x/7x use the IRC as the clock source. Software may later switch to one of the other available clock sources. 7.33.1.2 Main oscillator The main oscillator can be used as the clock source for the CPU, with or without using the PLL. The main oscillator also provides the clock source for the alternate PLL1. The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the main PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock frequency is referred to as CCLK elsewhere in this document. The frequencies of PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The clock frequency for each peripheral can be selected individually and is referred to as PCLK. Refer to Section 7.33.2 for additional information.

All rights reserved. 61 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller 7.33.1.3 RTC oscillator The RTC oscillator provides a 1 Hz clock to the RTC and a 32 kHz clock output that can be output on the CLKOUT pin in order to allow trimming the RTC oscillator without interference from a probe. 7.33.1.4 Watchdog oscillator The Watchdog Timer has a dedicated watchdog oscillator that provides a 500 kHz clock to the Watchdog Timer. The watchdog oscillator is always running if the Watchdog Timer is enabled. The Watchdog oscillator clock can be output on the CLKOUT pin in order to allow observe its frequency. In order to allow Watchdog Timer operation with minimum power consumption, which can be important in reduced power modes, the Watchdog oscillator frequency is not tightly controlled. The Watchdog oscillator frequency will vary over temperature and power supply within a particular part, and may vary by processing across different parts. This variation should be taken into account when determining Watchdog reload values. Within a particular part, temperature and power supply variations can produce up to a 17 % frequency variation. Frequency variation between devices under the same operating conditions can be up to 30 %. 7.33.2 Main PLL (PLL0) and Alternate PLL (PLL1) PLL0 (also called the Main PLL) and PLL1 (also called the Alternate PLL) are functionally identical but have somewhat different input possibilities and output connections. These possibilities are shown in Figure 7. The Main PLL can receive its input from either the IRC or the main oscillator and can potentially be used to provide the clocks to nearly everything on the device. The Alternate PLL receives its input only from the main oscillator and is intended to be used as an alternate source of clocking to the USB. The USB has timing needs that may not always be filled by the Main PLL. Both PLLs are disabled and powered off on reset. If the Alternate PLL is left disabled, the USB clock can be supplied by PLL0 if everything is set up to provide 48 MHz to the USB clock through that route. The source for each clock must be selected via the CLKSEL registers and can be further reduced by clock dividers as needed. PLL0 accepts an input clock frequency from either the IRC or the main oscillator. If only the Main PLL is used, then its output frequency must be an integer multiple of all other clocks needed in the system. PLL1 takes its input only from the main oscillator, requiring an external crystal in the range of 10 to 25 MHz. In each PLL, the Current Controlled Oscillator (CCO) operates in the range of 156 MHz to 320 MHz, so there are additional dividers to bring the output down to the desired frequencies. The minimum output divider value is 2, insuring that the output of the PLLs have a 50 % duty cycle. If the USB is used, the possibilities for the CPU clock and other clocks will be limited by the requirements that the frequency be precise and very low jitter, and that the PLL0 output must be a multiple of 48 MHz. Even multiples of 48 MHz that are within the operating range of the PLL are 192 MHz and 288 MHz. Also, only the main oscillator in conjunction with the PLL can meet the precision and jitter specifications for USB. It is due to these limitations that the Alternate PLL is provided.

All rights reserved. 62 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller The alternate PLL accepts an input clock frequency from the main oscillator in the range of 10 MHz to 25 MHz only. When used as the USB clock, the input frequency is multiplied up to a multiple of 48 MHz (192 MHz or 288 MHz as described above). 7.33.3 Wake-up timer The LPC178x/7x begin operation at power-up and when awakened from Power-down mode by using the 12 MHz IRC oscillator as the clock source. This allows chip operation to resume quickly. If the main oscillator or the PLL is needed by the application, software will need to enable these features and wait for them to stabilize before they are used as a clock source. When the main oscillator is initially activated, the wake-up timer allows software to ensure that the main oscillator is fully functional before the processor uses it as a clock source and starts to execute instructions. This is important at power on, all types of reset, and whenever any of the aforementioned functions are turned off for any reason. Since the oscillator and other functions are turned off during Power-down mode, any wake-up of the processor from Power-down mode makes use of the wake-up Timer. The wake-up timer monitors the crystal oscillator to check whether it is safe to begin code execution. When power is applied to the chip, or when some event caused the chip to exit Power-down mode, some time is required for the oscillator to produce a signal of sufficient amplitude to drive the clock logic. The amount of time depends on many factors, including the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its electrical characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient conditions. 7.33.4 Power control The LPC178x/7x support a variety of power control features. There are four special modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, the peripheral power control allows shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Each of the peripherals has its own clock divider which provides even better power control. The integrated PMU (Power Management Unit) automatically adjusts internal regulators to minimize power consumption during Sleep, Deep-sleep, Power-down, and Deep power-down modes. The LPC178x/7x also implement a separate power domain to allow turning off power to the bulk of the device while maintaining operation of the RTC and a small set of registers for storing data during any of the power-down modes. 7.33.4.1 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence other than re-enabling the clock to the ARM core. LPC178X_7X Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 5.5 — 26 April 2016 © NXP Semiconductors N.V. 2016. All rights reserved. 63 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller In Sleep mode, execution of instructions is suspended until either a Reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. The DMA controller can continue to work in Sleep mode and has access to the peripheral RAMs and all peripheral registers. The flash memory and the main SRAM are not available in Sleep mode, they are disabled in order to save power. Wake-up from Sleep mode will occur whenever any enabled interrupt occurs. 7.33.4.2 Deep-sleep mode In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks. The processor state and registers, peripheral registers, and internal SRAM values are preserved throughout Deep-sleep mode and the logic levels of chip pins remain static. The output of the IRC is disabled but the IRC is not powered down to allow fast wake-up. The RTC oscillator is not stopped because the RTC interrupts may be used as the wake-up source. The PLL is automatically turned off and disconnected. The clock divider registers are automatically reset to zero. The Deep-sleep mode can be terminated and normal operation resumed by either a Reset or certain specific interrupts that are able to function without clocks. Since all dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power consumption to a very low value. Power to the flash memory is left on in Deep-sleep mode, allowing a very quick wake-up. Wake-up from Deep-sleep mode can initiated by the NMI, External Interrupts EINT0 through EINT3, GPIO interrupts, the Ethernet Wake-on-LAN interrupt, Brownout Detect, an RTC Alarm interrupt, a USB input pin transition (USB activity interrupt), a CAN input pin transition, or a Watchdog Timer time-out, when the related interrupt is enabled. Wake-up will occur whenever any enabled interrupt occurs. On wake-up from Deep-sleep mode, the code execution and peripherals activities will resume after four cycles expire if the IRC was used before entering Deep-sleep mode. If the main external oscillator was used, the code execution will resume when 4096 cycles expire. PLL and clock dividers need to be reconfigured accordingly. 7.33.4.3 Power-down mode Power-down mode does everything that Deep-sleep mode does but also turns off the power to the IRC oscillator and the flash memory. This saves more power but requires waiting for resumption of flash operation before execution of code or data access in the flash memory can be accomplished. When the chip enters Power-down mode, the IRC, the main oscillator, and all clocks are stopped. The RTC remains running if it has been enabled and RTC interrupts may be used to wake up the CPU. The flash is forced into Power-down mode. The PLLs are automatically turned off and the clock selection multiplexers are set to use the system clock sysclk (the reset state). The clock divider control registers are automatically reset to zero. If the Watchdog timer is running, it will continue running in Power-down mode.

All rights reserved. 64 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller On the wake-up of Power-down mode, if the IRC was used before entering Power-down mode, it will take IRC 60 s to start-up. After this, four IRC cycles will expire before the code execution can then be resumed if the code was running from SRAM. In the meantime, the flash wake-up timer then counts 12 MHz IRC clock cycles to make the 100 s flash start-up time. When it times out, access to the flash will be allowed. Users need to reconfigure the PLL and clock dividers accordingly. 7.33.4.4 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip with the exception of the RTC module and the RESET pin. To optimize power conservation, the user has the additional option of turning off or retaining power to the 32 kHz oscillator. It is also possible to use external circuitry to turn off power to the on-chip regulator via the VDD(REG)(3V3) pins and/or the I/O power via the VDD(3V3) pins after entering Deep Power-down mode. Power must be restored before device operation can be restarted. The LPC178x/7x can wake up from Deep power-down mode via the RESET pin or an alarm match event of the RTC. 7.33.4.5 Wake-up Interrupt Controller (WIC) The WIC allows the CPU to automatically wake up from any enabled priority interrupt that can occur while the clocks are stopped in Deep-sleep, Power-down, and Deep power-down modes. The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When the CPU enters Deep-sleep, Power-down, or Deep power-down mode, the NVIC sends a mask of the current interrupt situation to the WIC.This mask includes all of the interrupts that are both enabled and of sufficient priority to be serviced immediately. With this information, the WIC simply notices when one of the interrupts has occurred and then it wakes up the CPU. The WIC eliminates the need to periodically wake up the CPU and poll the interrupts resulting in additional power savings. 7.33.5 Peripheral power control A power control for peripherals feature allows individual peripherals to be turned off if they are not needed in the application, resulting in additional power savings. 7.33.6 Power domains The LPC178x/7x provide two independent power domains that allow the bulk of the device to have power removed while maintaining operation of the RTC and the backup registers. On the LPC178x/7x, I/O pads are powered by VDD(3V3), while VDD(REG)(3V3) powers the on-chip voltage regulator which in turn provides power to the CPU and most of the peripherals. Depending on the LPC178x/7x application, a design can use two power options to manage power consumption. LPC178X_7X Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 5.5 — 26 April 2016 © NXP Semiconductors N.V. 2016. All rights reserved. 65 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller The first option assumes that power consumption is not a concern and the design ties the VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power supply for both pads, the CPU, and peripherals. While this solution is simple, it does not support powering down the I/O pad ring “on the fly” while keeping the CPU and peripherals alive. The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator powered independently from the I/O pad ring enables shutting down of the I/O pad power supply “on the fly” while the CPU and peripherals stay active. The VBAT pin supplies power only to the RTC domain. The RTC operates at very low power, which can be supplied by an external battery. The device core power (VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. There is no power drain from the RTC battery when VDD(REG)(3V3) is at nominal levels and VDD(REG)(3V3) > VBAT.

All rights reserved. 66 of 126 LPC178x/7x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller 7.34 System control 7.34.1 Reset Reset has four sources on the LPC178x/7x: the RESET pin, the Watchdog reset, Power-On Reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating voltage attains a usable level, starts the Wake-up timer (see description in Section 7.33.3), causing reset to remain asserted until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks have passed, and the flash controller has completed its initialization. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. 7.34.2 Brownout detection The LPC178x/7x include 2-stage monitoring of the voltage on the VDD(REG)(3V3) pins. If this voltage falls below 2.2 V (typical), the BOD asserts an interrupt signal to the Vectored Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a dedicated status register. The second stage of low-voltage detection asserts a reset to inactivate the LPC178x/7x when the voltage on the VDD(REG)(3V3) pins falls below 1.85 V (typical). This reset prevents alteration of the flash as operation of the various elements of the chip would otherwise become unreliable due to low voltage. The BOD circuit maintains this reset down below 1 V, at which point the power-on reset circuitry maintains the overall reset. Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event loop to sense the condition. 7.34.3 Code security (Code Read Protection - CRP) This feature of the LPC178x/7x allows user to enable different levels of security in the system so that access to the on-chip flash and use of the JTAG and ISP can be restricted. When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. There are three levels of the Code Read Protection. CRP1 disables access to chip via the JTAG and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased. CRP2 disables access to chip via the JTAG and only allows full flash erase and update using a reduced set of the ISP commands. Running an application with level CRP3 selected fully disables any access to chip via the JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too. It is up to the user’s application to provide (if needed) flash update mechanism using IAP calls or call reinvoke ISP command to enable flash update via UART0.

This matrix connects the instruction (I-code) and data (D-code) CPU buses of the ARM Cortex-M3 to the flash memory, the main (64 kB) SRAM, and the Boot ROM. The GPDMA can also access all of these memories. Additionally, the matrix connects the CPU system bus and all of the DMA controllers to the various peripheral functions. 7.34.6 External interrupt inputs The LPC178x/7x include up to 30 edge sensitive interrupt inputs combined with one level sensitive external interrupt input as selectable pin function. The external interrupt input can optionally be used to wake up the processor from Power-down mode. 7.34.7 Memory mapping control The Cortex-M3 incorporates a mechanism that allows remapping the interrupt vector table to alternate locations in the memory map. This is controlled via the Vector Table Offset Register contained in the NVIC. The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address space. The vector table must be located on a 128 word (512 byte) boundary because the NVIC on the LPC178x/7x is configured for 128 total interrupts. 7.35 Debug control Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and trace functions are supported in addition to a standard JTAG debug and parallel trace functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four watch points. LPC178X_7X Product data sheet All information provided in this document is subject to legal disclaimers.
