Description

General part information

STM32L151RE Series

The ultra-low-power STM32L151xE and STM32L152xE 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 512 Kbytes and RAM up to 80 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32L151xE and STM32L152xE devices offer two operational amplifiers, one 12-bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32-bit timer, six general-purpose 16-bit timers and two basic timers, which can be used as time bases.

Moreover, the STM32L151xE and STM32L152xE devices contain standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2S, three USARTs, two UARTs and an USB. The STM32L151xE and STM32L152xE devices offer up to 34 capacitive sensing channels to simply add a touch sensing functionality to any application.
