Description

The ultra-low-power STM32L100RC device incorporates the connectivity power of the
universal serial bus (USB) with the high-performance ARM
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.
It also includes a real-time clock and a set of backup registers that remain powered in
Standby mode.
Finally, the integrated LCD controller has a built-in LCD voltage generator that allows to
drive up to 8 multiplexed LCDs with the contrast independent of the supply voltage.
The ultra-low-power STM32L100RC device operates from a 1.8 to 3.6 V power supply
(down to 1.65 V at power down) with BOR and from a 1.65 to 3.6 V power supply without
BOR option. It is available in the -40 to +85 °C and -40 to +105 °C temperature ranges. A
comprehensive set of power-saving modes allows the design of low-power applications.
