SiM3C1xx  
4. Precision32™ SiM3C1xx System Overview  
The SiM3C1xx Precision32™ devices are fully integrated, mixed-signal system-on-a-chip MCUs. Highlighted  
features are listed below. Refer to Table 6.1 for specific product feature selection and part ordering numbers.  
Core:  
32-bit ARM Cortex-M3 CPU.  
80 MHz maximum operating frequency.  
Branch target cache and prefetch buffers to minimize wait states.  
Memory: 32–256 kB Flash; in-system programmable, 8–32 kB SRAM (including 4 kB retention SRAM,  
which preserves state in PM9 mode).  
Power:  
Low drop-out (LDO) regulator for CPU core voltage.  
Power-on reset circuit and brownout detectors.  
3.3 V output LDO for direct power from 5 V supplies.  
External transistor regulator.  
Power Management Unit (PMU).  
I/O: Up to 65 total multifunction I/O pins:  
Up to six programmable high-power capable (5–300 mA, 1.8–5 V).  
Up to twelve 5 V tolerant general purpose pins.  
Two flexible peripheral crossbars for peripheral routing.  
Clock Sources:  
Internal oscillator with PLL: 2380 MHz with ± 1.5% accuracy in free-running mode.  
Low-power internal oscillator: 20 MHz and 2.5 MHz modes.  
Low-frequency internal oscillator: 16.4 kHz.  
External RTC crystal oscillator: 32.768 kHz.  
External oscillator: Crystal, RC, C, CMOS clock modes.  
Programmable clock divider allows any oscillator source to be divided by binary factor from 1-128.  
Data Peripherals:  
16-Channel DMA Controller.  
128/192/256-bit Hardware AES Encryption.  
16/32-bit CRC.  
Timers/Counters and PWM:  
6-channel Enhanced Programmable Counter Array (EPCAn) supporting advanced PWM and capture/compare.  
2 x 2-channel Standard Programmable Counter Array (PCAn) supporting PWM and capture/compare.  
2 x 32-bit Timers - can be split into 4 x 16-bit Timers, support PWM and capture/compare.  
Real Time Clock (RTCn).  
Low Power Timer.  
Watchdog Timer.  
Communications Peripherals:  
External Memory Interface.  
2 x USARTs and 2 x UARTs with IrDA and ISO7816 SmartCard support.  
3 x SPIs.  
2 x I2C.  
I2S (receive and transmit).  
Analog:  
2 x 12-Bit Analog-to-Digital Converters (SARADC).  
2 x 10-Bit Digital-to-Analog Converter (IDAC).  
16-Channel Capacitance-to-Digital Converter (CAPSENSE).  
2 x Low-Current Comparators (CMP).  
1 x Current-to-Voltage Converter (IVC) module with two channels.  
On-Chip Debugging  
With on-chip power-on reset, voltage supply monitor, watchdog timer, and clock oscillator, the SiM3C1xx devices  
are truly standalone system-on-a-chip solutions. The Flash memory is reprogrammable in-circuit, providing non-
