4.1 STM32L100RCT6
microcontroller
The Value Line STM32L100RCT6 incorporates the connectivity power of the universal serial
bus (USB) with the high-performance ARM Cortex™-M3 32-bit RISC core operating at a
32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories
(256 Kbytes of Flash memory and 16 Kbytes of RAM) and an extensive range of enhanced
I/Os and peripherals connected to two APB buses.
The STM32L100RCT6 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 STM32L100RCT6 device contains standard and advanced communication
interfaces: two I2Cs, three SPIs, two I2S, three USARTs and a 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 you to
drive up to 8 multiplexed LCDs with contrast independent of the supply voltage.
The ultra-low-power STM32L100RCT6 operates from a 1.8 to 3.6 V power supply with
BOR. It is available in the -40 to +85 °C temperature range. A comprehensive set of power-
saving modes allows the design of low-power applications.
