Description

General part information

STM32L100R8-A Series

The ultra-low-power STM32L100RC device incorporates the connectivity power of the universal serial bus (USB) with the high-performance ARM®Cortex®-M3 32-bit RISC core operating at a frequency of 32 MHz (33.3 DMIPS), a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 256 Kbytes and RAM up to 16 Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32L100RC device offers one 12-bit ADC, two DACs, two ultra-low-power comparators, six general-purpose 16-bit timers and two basic timers, which can be used as time bases.

Moreover, the STM32L100RC device contains standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2S, three USARTs, and an USB.
