It packs 64 KB of Flash program memory, 8 KB of SRAM, and 2 KB of embedded EEPROM, all in a 64-ball TFBGA package measuring 5x5 mm. ## Memory map and field-update reality The 2 KB EEPROM emulated in Flash (or the dedicated 2 KB true EEPROM block) handles calibration constants and fault logs without wearing the main program store. With 8 KB RAM, you are not running a TCP/IP stack with large buffers; keep DMA transfers under 2 KB to avoid heap fragmentation. ## Industrial temperature and package constraints","metaTitle":"ST STM32L051R8H6TR ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L051R8H6TR 32-bit MCU, 32 MHz Cortex-M0+, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 64-TFBGA, -40 to 85°C.
