STM32L100C6U6TR

ARM Cortex-M3 32MHz 闪存：32K@x8bit RAM：4KB

The ultra-low-power STM32L100C6 and STM32L100R8/RB devices incorporate 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 128 Kbytes and RAM up to 10 Kbytes and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

All the 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 STM32L100C6 and STM32L100R8/RB 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 to drive up to 8 multiplexed LCDs with contrast independent of the supply voltage.

The ultra-low-power STM32L100C6 and STM32L100R8/RB devices operate from a 1.8 to 3.6 V power supply. They are available in the -40 to +85 °C temperature range. A comprehensive set of power-saving modes allows the design of low-power applications.
