Individual interrupt flags may also represent more than one interrupt source. 7.7 IOCON block The IOCON block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Peripherals should be connected to the appropriate pins prior to being activated and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined. 7.7.1 Features • Programmable pull-up, pull-down, or repeater mode. • All GPIO pins (except PIO0_4 and PIO0_5) are pulled up to 3.3 V (VDD = 3.3 V) if their pull-up resistor is enabled. • Programmable pseudo open-drain mode. • Programmable 10-ns glitch filter on pins PIO0_22, PIO0_23, and PIO0_11 to PIO0_16. The glitch filter is turned off by default. • Programmable hysteresis. • Programmable input inverter. 7.8 General Purpose Input/Output GPIO Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs can be set or cleared in one write operation. LPC1315/16/17/45/46/47 use accelerated GPIO functions: • GPIO registers are a dedicated AHB peripheral so that the fastest possible I/O timing can be achieved. • Entire port value can be written in one instruction. Any GPIO pin providing a digital function can be programmed to generate an interrupt on a level, a rising or falling edge, or both. The GPIO block consists of three parts: 1. The GPIO ports. 2. The GPIO pin interrupt block to control eight GPIO pins selected as pin interrupts. 3. Two GPIO group interrupt blocks to control two combined interrupts from all GPIO pins.

It can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the slave and from the slave to the master. In practice, often only one of these data flows carries meaningful data. 7.11.1 Features • Maximum SSP speed of 25 Mbit/s (master) or 4.17 Mbit/s (slave) (in SSP mode) • Compatible with Motorola SPI, 4-wire Texas Instruments SSI, and National Semiconductor Microwire buses • • • • Synchronous serial communication Master or slave operation 8-frame FIFOs for both transmit and receive 4-bit to 16-bit frame 7.12 I2C-bus serial I/O controller The LPC1315/16/17/45/46/47 contain one I2C-bus controller. 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 I2C is a multi-master bus and can be controlled by more than one bus master connected to it. 7.12.1 Features • The I2C-interface is an I2C-bus compliant interface with open-drain pins. The I2C-bus interface supports Fast-mode Plus with bit rates up to 1 Mbit/s. • • • • • Easy to configure as master, slave, or master/slave. Programmable clocks allow versatile rate control. Bidirectional data transfer between masters and slaves. Multi-master bus (no central master). Arbitration between simultaneously transmitting masters without corruption of serial data on the bus. • Serial clock synchronization allows devices with different bit rates to communicate via one serial bus. • Serial clock synchronization can be used as a handshake mechanism to suspend and resume serial transfer. • The I2C-bus can be used for test and diagnostic purposes. • The I2C-bus controller supports multiple address recognition and a bus monitor mode. 7.13 12-bit ADC The LPC1315/16/17/45/46/47 contains one ADC. It is a single 12-bit successive approximation ADC with eight channels. 7.13.1 Features • • • • • 12-bit successive approximation ADC. • • • • 12-bit conversion rate of up to 500 kHz. Input multiplexing among 8 pins and three internal sources. Low-power mode. 10-bit double-conversion rate mode (conversion rate of up to 1 Msample/s). Measurement range VREFN to VREFP (typically 3 V; not to exceed VDDA voltage level). Burst conversion mode for single or multiple inputs. Optional conversion on transition of input pin or timer match signal. On the LQFP64 package, power and reference pins (VDDA, VSSA, VREFP, VREFN) are brought out on separate pins for superior noise immunity. 7.14 General purpose external event counter/timers The LPC1315/16/17/45/46/47 includes two 32-bit counter/timers and two 16-bit counter/timers. The counter/timer is designed to count cycles of the system derived clock. It can optionally generate interrupts or perform other actions at specified timer values, based on four match registers. Each counter/timer also includes one capture input to trap the timer value when an input signal transitions, optionally generating an interrupt.

This feature permits easy pulse-width measurement by clearing the timer on the leading edge of an input pulse and capturing the timer value on the trailing edge. 7.15 Repetitive Interrupt (RI) timer The repetitive interrupt timer provides a free-running 48-bit counter which is compared to a selectable value, generating an interrupt when a match occurs. Any bits of the timer/compare can be masked such that they do not contribute to the match detection. The repetitive interrupt timer can be used to create an interrupt that repeats at predetermined intervals. 7.15.1 Features • 48-bit counter running from the main clock. Counter can be free-running or can be reset when an RIT interrupt is generated. • 48-bit compare value. • 48-bit compare mask. An interrupt is generated when the counter value equals the compare value, after masking.

This gives a wide range of potential timing choices of watchdog operation under different power conditions. 7.18 Clocking and power control 7.18.1 Integrated oscillators The LPC1315/16/17/45/46/47 include three independent oscillators. These are the system oscillator, the Internal RC oscillator (IRC), and the watchdog oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Following reset, the LPC1315/16/17/45/46/47 will operate from the internal RC oscillator until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 9 for an overview of the LPC1315/16/17/45/46/47 clock generation.

The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1 % accuracy over the entire voltage and temperature range.

All rights reserved. 32 of 77 LPC1315/16/17/45/46/47 NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller Upon power-up, any chip reset, or wake-up from Deep power-down mode, the LPC1315/16/17/45/46/47 use the IRC as the clock source. Software may later switch to one of the other available clock sources. 7.18.1.2 System oscillator The system oscillator can be used as the clock source for the CPU, with or without using the PLL. On the LPC1315/16/17/45/46/47, the system oscillator must be used to provide the clock source to USB. The system 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 system PLL. 7.18.1.3 Watchdog oscillator The watchdog oscillator can be used as a clock source that directly drives the CPU, the watchdog timer, or the CLKOUT pin. The watchdog oscillator nominal frequency is programmable between 9.4 kHz and 2.3 MHz. The frequency spread over processing and temperature is 40 % (see also Table 13). 7.18.2 System PLL and USB PLL The LPC1315/16/17/45/46/47 contain a system PLL and a dedicated PLL for generating the 48 MHz USB clock. The system and USB PLLs are identical. The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency. The output divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. The PLL output frequency must be lower than 100 MHz. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 s. 7.18.3 Clock output The LPC1315/16/17/45/46/47 features a clock output function that routes the IRC oscillator, the system oscillator, the watchdog oscillator, or the main clock to an output pin. 7.18.4 Wake-up process The LPC1315/16/17/45/46/47 begin operation at power-up and when awakened from Deep 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. 7.18.5 Power control The LPC1315/16/17/45/46/47 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 LPC1315_16_17_45_46_47 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 3 — 20 September 2012 © NXP B.V. 2012. All rights reserved. 33 of 77 LPC1315/16/17/45/46/47 NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller 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, a register is provided for 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. Selected peripherals have their own clock divider which provides even better power control. 7.18.5.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through simple calls to the power profile. The power configuration routine configures the LPC1315/16/17/45/46/47 for one of the following power modes: • Default mode corresponding to power configuration after reset. • CPU performance mode corresponding to optimized processing capability. • Efficiency mode corresponding to optimized balance of current consumption and CPU performance. • Low-current mode corresponding to lowest power consumption. In addition, the power profile includes routines to select the optimal PLL settings for a given system clock and PLL input clock. Remark: When using the USB, configure the LPC1345/46/47 in Default mode. 7.18.5.2 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 but re-enabling the clock to the ARM core. 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. 7.18.5.3 Deep-sleep mode In Deep-sleep mode, the LPC1315/16/17/45/46/47 is in Sleep-mode and all peripheral clocks and all clock sources are off with the exception of the IRC. The IRC output is disabled unless the IRC is selected as input to the watchdog timer. In addition all analog blocks are shut down and the flash is in stand-by mode. In Deep-sleep mode, the user has the option to keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC1315/16/17/45/46/47 can wake up from Deep-sleep mode via reset, selected GPIO pins, a watchdog timer interrupt, or an interrupt generating USB port activity. Deep-sleep mode saves power and allows for short wake-up times. LPC1315_16_17_45_46_47 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 34 of 77 LPC1315/16/17/45/46/47 NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller 7.18.5.4 Power-down mode In Power-down mode, the LPC1315/16/17/45/46/47 is in Sleep-mode and all peripheral clocks and all clock sources are off with the exception of watchdog oscillator if selected. In addition all analog blocks and the flash are shut down. In Power-down mode, the user has the option to keep the BOD circuit running for BOD protection. The LPC1315/16/17/45/46/47 can wake up from Power-down mode via reset, selected GPIO pins, a watchdog timer interrupt, or an interrupt generating USB port activity. Power-down mode reduces power consumption compared to Deep-sleep mode at the expense of longer wake-up times. 7.18.5.5 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip with the exception of the WAKEUP pin. The LPC1315/16/17/45/46/47 can wake up from Deep power-down mode via the WAKEUP pin. The LPC1315/16/17/45/46/47 can be prevented from entering Deep power-down mode by setting a lock bit in the PMU block. Locking out Deep power-down mode enables the user to always keep the watchdog timer or the BOD running. When entering Deep power-down mode, an external pull-up resistor is required on the WAKEUP pin to hold it HIGH. The RESET pin must also be held HIGH to prevent it from floating while in Deep power-down mode. 7.18.6 System control 7.18.6.1 Reset Reset has four sources on the LPC1315/16/17/45/46/47: 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 IRC and initializes the flash controller. A LOW-going pulse as short as 50 ns resets the part. 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. An external pull-up resistor is required on the RESET pin if Deep power-down mode is used. 7.18.6.2 Brownout detection The LPC1315/16/17/45/46/47 includes up to four levels for monitoring the voltage on the VDD pin. If this voltage falls below one of selected levels, the BOD asserts an interrupt signal to the NVIC. 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. Four threshold levels can be selected to cause a forced reset of the chip. LPC1315_16_17_45_46_47 Product data sheet All information provided in this document is subject to legal disclaimers.

When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. In addition, ISP entry via the PIO0_1 pin can be disabled without enabling CRP. For details see the LPC1315/16/17/45/46/47 user manual. There are three levels of Code Read Protection: 1. CRP1 disables access to the chip via the SWD 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. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using PIO0_1 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 the USART. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device. In addition to the three CRP levels, sampling of pin PIO0_1 for valid user code can be disabled. For details see the LPC1315/16/17/45/46/47 user manual. 7.18.6.4 APB interface The APB peripherals are located on one APB bus. 7.18.6.5 AHBLite The AHBLite connects the CPU bus of the ARM Cortex-M3 to the flash memory, the main static RAM, and the ROM. 7.18.6.6 External interrupt inputs All GPIO pins can be level or edge sensitive interrupt inputs. 7.19 Emulation and debugging Debug functions are integrated into the ARM Cortex-M3. Serial wire debug functions are supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0 is configured to support up to four breakpoints and two watch points.

[3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [5] Cb = total capacitance of one bus line in pF. [6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing.

This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. tf SDA tSU;DAT 70 % 30 % 70 % 30 % tHD;DAT tf 70 % 30 % SCL tVD;DAT tHIGH 70 % 30 % 70 % 30 % 70 % 30 % tLOW S 1 / fSCL 002aaf425 Fig 24.

USB interface on a bus-powered device 12.2 XTAL input The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed. LPC1315_16_17_45_46_47 Product data sheet All information provided in this document is subject to legal disclaimers.

Slave mode operation of the on-chip oscillator In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 30), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 31 and in Table 18 and Table 19. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (the fundamental frequency is represented by L, CL and RS). Capacitance CP in Figure 31 represents the parallel package capacitance and should not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal manufacturer.

Take care that the load capacitors Cx1, Cx2, and Cx3 in case of third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plain. Loops must be made as small as possible in order to keep the noise coupled in via the PCB as small as possible. Also parasitics should stay as small as possible. Values of Cx1 and Cx2 should be chosen smaller accordingly to the increase in parasitics of the PCB layout.

Reset pad configuration 12.6 ADC usage notes The following guidelines show how to increase the performance of the ADC in a noisy environment beyond the ADC specifications listed in Table 17: • The ADC input trace must be short and as close as possible to the LPC1315/16/17/45/46/47 chip. • The ADC input traces must be shielded from fast switching digital signals and noisy power supply lines. • Because the ADC and the digital core share the same power supply, the power supply line must be adequately filtered. • To improve the ADC performance in a very noisy environment, put the device in Sleep mode during the ADC conversion. Remark: On the LQFP64 package, the analog power supply and the reference voltage can be connected on separate pins for better noise immunity.
