Ultra-low-power 32-bit Value Line ARM Cortex-M3 MCU with 32 Kbytes Flash, 32 MHz CPU, LCD, USB
The Ultra-low-power STM32L100xx 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 (Flash memory up to 128 Kbytes and RAM up to 10 Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
All devices offer a 12-bit ADC, 2 DACs and 2 Ultra-low-power comparators, six general-purpose 16-bit timers and two basic timers, which can be used as time bases.
Moreover, the STM32L100xx devices contain standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs and a USB.
They also include a real-time clock with sub-second counting 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 STM32L100xx operates from a 1.8 to 3.6 V power supply. 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.
