STM32L1 up to 512KB Flash

Question asked by Amel N Employee on Mar 5, 2014
STMicroelectronics has extended its STM32 L1 series of ultra-low-power ARM®Cortex®-M3 32-bit microcontrollers with new 512KB flash devices.


Key features of the L1 series include:

  • High-performance ARM Cortex-M3 32-bit core: up to 33 DMIPS operating at 32MHz;
  • Pin-to-pin and software compatibility with all previous STM32 L1 devices;
  • Run-mode dynamic power consumption 257µA/MHz at 32MHz down to 177µA/MHz @ 4MHz
  • Two ultra-low-power modes: down to 435nA with SRAM retention;
  • True embedded EEPROM;
  • Dual-bank flash allowing fast and fail-safe firmware updates and rollback, thanks to the RWW (Read While-Write) capabilities.
The STM32 L1 512KB is supported by an STM32 Nucleo extension board with mbed-enabled.
