STM32L152QEH6 Description

The ultra-low-power STM32L152QEH6 incorporates 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 /Os and peripherals connected to two APB buses. The STM32L152QEH6 offers 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.
