Debugging With on-chip power-on reset, voltage supply monitor, watchdog timer, and clock oscillator, the SiM3U1xx devices are truly standalone system-on-a-chip solutions. The Flash memory is reprogrammable in-circuit, providing nonvolatile data storage and allowing field upgrades of the firmware. User firmware has complete control of all peripherals and may individually shut down and gate the clocks of any or all peripherals for power savings. The on-chip debugging interface (SWJ-DP) allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping, and run and halt commands. All analog and digital peripherals are fully functional while debugging. Each device is specified for 1.8 to 3.6 V operation over the industrial temperature range (–40 to +85 °C). The Port I/O and RESET pins are powered from the IO supply voltage. The SiM3U1xx devices are available in 40-pin or 64pin QFN, 64-pin or 80-pin TQFP, or 92-pin LGA packages. All package options are lead-free and RoHS compliant. See Table 5.1 for ordering information. A block diagram is included in Figure 4.1.

LDO and Voltage Regulator (VREG0) The SiM3U1xx devices include two internal regulators: the core LDO Regulator and the Voltage Regulator (VREG0). The LDO Regulator converts a 1.8–3.6 V supply to the core operating voltage of 1.8 V. This LDO consumes little power and provides flexibility in choosing a power supply for the system. The Voltage Regulator regulates from 5.5 to 2.7 V and can serve as an input to the LDO. This allows the device to be powered from USB without any external components other than bypass capacitors. 4.1.2. Voltage Supply Monitor (VMON0) The SiM3U1xx devices include a voltage supply monitor which allows devices to function in known, safe operating condition without the need for external hardware. The supply monitor includes additional circuitry that can monitor the main supply voltage and the VREGIN input voltage divided by 4 (VREGIN / 4). The supply monitor module includes the following features: Main supply “VDD Low” (VDD below the early warning threshold) notification. Holds the device in reset if the main VDD supply drops below the VDD Reset threshold. VREGIN divided by 4 (VREGIN / 4) supply “VREGIN Low” notification. 4.1.3. External Regulator (EXTVREG0) The External Regulator provides all the circuitry needed for a high-power regulator except the power transistor (NPN or PNP) and current sensing resistor (if current limiting is enabled). The External Regulator module has the following features: Interfaces with either an NPN or PNP external transistor that serves as the pass device for the high current regulator. Automatic current limiting. Automatic foldback limiting. Sources up to 1 A for use by external circuitry. Variable output voltage from 1.8–3.6 V in 100 mV steps. 4.1.4. Power Management Unit (PMU) The Power Management Unit on the SiM3U1xx manages the power systems of the device. On power-up, the PMU ensures the core voltages are a proper value before core instruction execution begins. It also recognizes and manages the various wake sources for low-power modes of the device. The PMU module includes the following features: Up to 16 pin wake inputs can wake the device from Power Mode 9. The Low Power Timer, RTC0 (alarms and oscillator fail), Comparator 0, and the RESET pin can also serve as wake sources for Power Mode 9. All PM9 wake sources (except for the RESET pin) can also reset the Low Power Timer or RTC0 modules. Disables the level shifters to pins and peripherals to further reduce power usage in PM9. These level shifters must be re-enabed by firmware after exiting PM9. Provides a PMU_Asleep signal to a pin as an indicator that the device is in PM9. Rev. 1.1 37 SiM3U1xx N ot R ec om m en de d fo r N ew D es ig ns 4.1.5. Device Power Modes The SiM3U1xx devices feature four low power modes in addition to normal operating mode. Several peripherals provide wake up sources for these low power modes, including the Low-Power Timer (LPT0), RTC0 (alarms and oscillator failure notification), Comparator 0, and PMU Pin Wake. In addition, all peripherals can have their clocks disabled to reduce power consumption whenever a peripheral is not being used using the clock control (CLKCTRL) registers. 4.1.5.1. Normal Mode (Power Mode 0) Normal Mode is the default mode of the device. The core and peripherals are fully operational, and instructions are executed from flash memory. 4.1.5.2. Power Mode 1 In Power Mode 1 the core and peripherals are fully operational, with instructions executing from RAM. Compared with Normal Mode, the active power consumption of the device in PM1 is reduced. Additionally, at higher speeds in PM1, the core throughput can also be increased because RAM does not require additional wait states that reduce the instruction fetch speed. 4.1.5.3. Power Mode 2 In Power Mode 2 the core halts and any enabled peripherals continue to run at the selected clock speed. The power consumption in PM2 corresponds to the AHB and APB clocks left enabled, thus the power can be tuned to the optimal level for the needs of the application. To place the device in PM2, the core should execute a wait-forinterrupt (WFI) or wait-for-event (WFE) instruction. If the WFI instruction is called from an interrupt service routine, the interrupt that wakes the device from PM2 must be of a sufficient priority to be recognized by the core. It is recommended to perform both a DSB (Data Synchronization Barrier) and an ISB (Instruction Syncronization Barrier) operation prior to the WFI to ensure all bus accesses complete. When operating from the LFOSC0 with the DMACTRL0 AHB clock disabled, PM2 can achieve similar power consumption to PM3, but with the ability to wake on APB-clocked interrupts. For example, enabling only the APB clock to the Ports will allow the firmware to wake on a PMATCH0, PBEXT0 or PBEXT1 interrupt with minimal impact on the supply current. 4.1.5.4. Power Mode 3 In Power Mode 3, the AHB and APB clocks are halted. The device may only wake from enabled interrupt sources which do not require the APB clock (RTC0ALRM, RTC0FAIL, LPTIMER0, VDDLOW and VREGLOW). A special fast wake option allows the device to operate at a very low level from the RTC0TCLK or LFOSC0 oscillator while in PM3, but quickly switch to the faster LPOSC0 when the wake event occurs. Because the current consumption of these blocks is minimal, it is recommended to use the fast wake option. The device will enter PM3 on a WFI or WFE instruction. Because all AHB master clocks are disabled, the LPOSC will automatically halt and go into a low-power suspended state. If the WFI instruction is called from an interrupt service routine, the interrupt that wakes the device from PM3 must be of a sufficient priority to be recognized by the core. It is recommended to perform both a DSB (Data Synchronization Barrier) and an ISB (Instruction Synchronization Barrier) operation prior to the WFI to ensure all bus access is complete. 4.1.5.5. Power Mode 9 In Power Mode 9, the core and all peripherals are halted, all clocks are stopped, and the pins and peripherals are set to a lower power mode. In addition, standard RAM contents are not preserved, though retention RAM contents are still available after exiting the power mode. This mode provides the lowest power consumption for the device, but requires an appropriate reset to exit. The available reset sources to wake from PM9 are controlled by the Power Management Unit (PMU). Before entering PM9, the desired reset source(s) should be configured in the PMU. The SLEEPDEEP bit in the ARM System Control Register should be set, and the PMSEL bit in the RSTSRC0_CONFIG register must be set to indicate that PM9 is the desired power mode. The device will enter PM9 on a WFI or WFE instruction, and remain in PM9 until a reset configured by the PMU occurs. It is recommended to perform both a DSB (Data Synchronization Barrier) and an ISB (Instruction Synchronization Barrier) operation prior to the WFI to ensure all bus access is complete. 38 Rev. 1.1 SiM3 U 1xx 4.2. I/O N ot R ec om m en de d fo r N ew D es ig ns 4.2.1. General Features The SiM3U1xx ports have the following features: Push-pull or open-drain output modes and analog or digital modes. Option for high or low output drive strength. Port Match allows the device to recognize a change on a port pin value. Internal pull-up resistors are enabled or disabled on a port-by-port basis. Two external interrupts with up to 16 inputs provide monitoring capability for external signals. Internal Pulse Generator Timer (PB2 only) to generate simple square waves. A subset of pins can also serve as inputs to the Port Mapped Level Shifters available on the High Drive Pins. 4.2.2. High Drive Pins (PB4) The High Drive pins have the following additional features: Programmable safe state: high, low, or high impedance. Programmable drive strength and slew rates. Programmable hardware current limiting. Powered from a separate source (VIOHD, which can be up to 6 V) from the rest of the device. Supports various functions, including GPIO, UART1 pins, EPCA0 pins, or Port Mapped Level Shifting. 4.2.3. 5 V Tolerant Pins (PB3) The 5 V tolerant pins can be connected to external circuitry operating at voltages above the device supply without needing extra components to shift the voltage level. 4.2.4. Crossbars The SiM3U1xx devices have two Crossbars with the following features: Flexible peripheral assignment to port pins. Pins can be individually skipped to move peripherals as needed for design or layout considerations. The Crossbars have a fixed priority for each I/O function and assign these functions to the port pins. When a digital resource is selected, the least-significant unassigned port pin is assigned to that resource. If a port pin is assigned, the Crossbars skip that pin when assigning the next selected resource. Additionally, the Crossbars will skip port pins whose associated bits in the PBSKIPEN registers are set. This provides some flexibility when designing a system: pins involved with sensitive analog measurements can be moved away from digital I/O and peripherals can be moved around the chip as needed to ease layout constraints. Rev. 1.1 39 SiM3U1xx 4.3. Clocking N ot R ec om m en de d fo r N ew D es ig ns The SiM3U1xx devices have two system clocks: AHB and APB. The AHB clock services memory peripherals and is derived from one of seven sources: the RTC0 timer clock (RTC0TCLK), the Low Frequency Oscillator, the Low Power Oscillator, the divided Low Power Oscillator, the External Oscillator, the PLL0 Oscillator, and the USB0 Oscillator. In addition, a divider for the AHB clock provides flexible clock options for the device. The APB clock services data peripherals and is synchronized with the AHB clock. The APB clock can be equal to the AHB clock (if AHB is less than or equal to 50 MHz) or set to the AHB clock divided by two. Clock Control allows the AHB and APB clocks to be turned off to unused peripherals to save system power. Any registers in a peripheral with disabled clocks will be unable to be accessed until the clocks are enabled. Most peripherals have clocks off by default after a power-on reset. 40 Rev. 1.1 SiM3 U 1xx N ot R ec om m en de d fo r N ew D es ig ns 4.3.1. PLL (PLL0) The PLL module consists of a dedicated Digitally-Controlled Oscillator (DCO) that can be used in Free-Running mode without a reference frequency, Frequency-Locked to a reference frequency, or Phase-Locked to a reference frequency. The reference frequency for Frequency-Lock and Phase-Lock modes can use one of multiple sources (including the USB0 oscillator or external oscillator) to provide maximum flexibility for different application needs. Because the PLL module generates its own clock, the DCO can be locked to a particular reference frequency and then moved to Free-Running mode to reduce system power and noise. The PLL module includes the following features: Five output ranges with output frequencies ranging from 23 to 80 MHz. Multiple reference frequency inputs. Three output modes: free-running DCO, frequency-locked, and phase-locked. Ability to sense the rising edge or falling edge of the reference source. DCO frequency LSB dithering to provide finer average output frequencies. Spectrum spreading to reduce generated system noise. Low jitter and fast lock times. Ability to suspend all output frequency updates (including dithering and spectrum spreading) using the STALL bit during jitter-sensitive operations. 4.3.2.

The IDAC module includes the following features: 10-bit current DAC with support for four timer, up to seven external I/O, on demand, and SSG0 output update triggers. Ability to update on rising, falling, or both edges for any of the external I/O trigger sources (DACnTx). Supports an output update rate greater than 600 k samples per second. Support for three full-scale output modes: 0.5 mA, 1.0 mA and 2.0 mA. Four-word FIFO to aid with high-speed waveform generation or DMA interactions. Individual FIFO overrun, underrun, and went-empty interrupt status sources. Support for multiple data packing formats, including: single 10-bit sample per word, dual 10-bit samples per word, or four 8-bit samples per word. Support for left- and right-justified data. 48 Rev. 1.1 SiM3 U 1xx N ot R ec om m en de d fo r N ew D es ig ns 4.7.4. 16-Channel Capacitance-to-Digital Converter (CAPSENSE0) The Capacitance Sensing module measures capacitance on external pins and converts it to a digital value. The CAPSENSE module has the following features: Multiple start-of-conversion sources (CSnTx). Option to convert to 12, 13, 14, or 16 bits. Automatic threshold comparison with programmable polarity (“less than or equal” or “greater than”). Four operation modes: single conversion, single scan, continuous single conversion, and continuous scan. Auto-accumulate mode that will take and average multiple samples together from a single start of conversion signal. Single bit retry options available to reduce the effect of noise during a conversion. Supports channel bonding to monitor multiple channels connected together with a single conversion. Scanning option allows the module to convert a single or series of channels and compare against the threshold while the AHB clock is stopped and the core is in a low power mode. 4.7.5. Low Current Comparators (CMP0, CMP1) The Comparators take two analog input voltages and output the relationship between these voltages (less than or greater than) as a digital signal. The Low Power Comparator module includes the following features: Multiple sources for the positive and negative poles, including VDD, VREF, and 8 I/O pins. Two outputs are available: a digital synchronous latched output and a digital asynchronous raw output. Programmable hysteresis and response time. Falling or rising edge interrupt options on the comparator output. 4.7.6. Current-to-Voltage Converter (IVC0) The IVC module provides inputs to the SARADCn modules so the input current can be measured. The IVC module has the following features: Two independent channels. Programmable input ranges (1–6 mA full-scale). Rev. 1.1 49 SiM3U1xx 4.8. Reset Sources N ot R ec om m en de d fo r N ew D es ig ns Reset circuitry allows the controller to be easily placed in a predefined default condition. On entry to this reset state, the following occur: The core halts program execution. Module registers are initialized to their defined reset values unless the bits reset only with a power-on reset. External port pins are forced to a known state. Interrupts and timers are disabled. Clocks to all AHB peripherals other than the USB0 buffers are enabled. Clocks to all APB peripherals other than Watchdog Timer, EMIF0, and DMAXBAR are disabled. All registers are reset to the predefined values noted in the register descriptions unless the bits only reset with a power-on reset. The contents of RAM are unaffected during a reset; any previously stored data is preserved as long as power is not lost. The Port I/O latches are reset to 1 in open-drain mode. Weak pullups are enabled during and after the reset. For VDD Supply Monitor and power-on resets, the RESET pin is driven low until the device exits the reset state. On exit from the reset state, the program counter (PC) is reset, and the system clock defaults to an internal oscillator. The Watchdog Timer is enabled with the Low Frequency Oscillator (LFO0) as its clock source. Program execution begins at location 0x00000000. 50 Rev. 1.1 SiM3 U 1xx 4.9. Security om m en de d fo r N ew D es ig ns The peripherals on the SiM3U1xx devices have a register lock and key mechanism that prevents any undesired accesses of the peripherals from firmware. Each bit in the PERIPHLOCKx registers controls a set of peripherals. A key sequence must be written in order to the KEY register to modify any of the bits in PERIPHLOCKx. Any subsequent write to KEY will then inhibit any accesses of PERIPHLOCKx until it is unlocked again through KEY. Reading the KEY register indicates the current status of the PERIPHLOCKx lock state. If a peripheral’s registers are locked, all writes will be ignored. The registers can always be read, regardless of the peripheral’s lock state. ec 4.10. On-Chip Debugging N ot R The SiM3U1xx devices include JTAG and Serial Wire programming and debugging interfaces and ETM for instruction trace. The JTAG interface is supported on SiM3U1x7 and SiM3U1x6 devices only, and does not include boundary scan capabiites. The ETM interface is supported on SiM3U1x7 devices. The JTAG and ETM interfaces can be optionally enabled to provide more visibility while debugging at the cost of using several Port I/O pins. Additionally, if the core is configured for Serial Wire (SW) mode and not JTAG, then the Serial Wire Viewer (SWV) is available to provide a single pin to send out TPIU messages on SiM3U1x7 and SiM3U1x6 devices. Most peripherals have the option to halt or continue functioning when the core halts in debug mode. Rev. 1.1 51 SiM3U1xx N ew D es ig ns 5. Ordering Information fo r Figure 5.1.

Revision Specific Behavior es ig ns This chapter details any known differences from behavior as stated in the device datasheet and reference manual. All known errata for the current silicon revision are rolled into this section at the time of publication. Any errata found after publication of this document will initially be detailed in a separate errata document until this datasheet is revised. 7.1. Revision Identification m en de d fo r N ew D The Lot ID Code on the top side of the device package can be used for decoding device revision information. Figures 7.1, 7.2, 7.3, and 7.4 show how to find the Lot ID Code on the top side of the device package. In addition, firmware can determine the revision of the device by checking the DEVICEID registers. N ot R ec om Figure 7.1. LGA-92 SiM3U1x7 Revision Information 90 Figure 7.2.

Comparator Rising/Falling Edge Flags in Debug Mode (CMP0, CMP1) N ot R ec 7.2.1. Problem On Revision A and Revision B devices, if the comparator output is high, the comparator rising and falling edge flags will both be set to 1 upon single-step or exit from debug mode. 7.2.2. Impacts Firmware using the rising and falling edge flags to make decisions may see a false trigger of the comparator if the output of the comparator is high during a debug session. This does not impact the non-debug operation of the device. 7.2.3. Workaround There is not a system-agnostic workaround for this issue. 7.2.4. Resolution This issue exists on Revision A and Revision B devices. It may be corrected in a future device revision.
