Active-production STM32L0 ultra-low-power MCU in a 5x5 BGA
It runs at 32 MHz and packs 192 KB of Flash program memory, 20 KB of SRAM, and 6 KB of true EEPROM — enough for a real-time control loop with a modest data log or configuration table.
192 KB Flash and 6 KB EEPROM — sizing the firmware budget
The 192 KB Flash (192K x 8) is the program store; the 6 KB EEPROM (6K x 8) handles calibration constants, node IDs, and fault logs without wearing the Flash. The 20 KB SRAM (20K x 8) is tight for a full TCP/IP stack but comfortable for a sensor fusion loop, a Modbus RTU slave, or a BLE host controller.
Peripherals and connectivity for sensor and control applications
The peripheral set includes brown-out detect, POR, DMA, I²S, PWM, and a watchdog timer. The 15-channel 12-bit ADC handles analog inputs like thermistors, strain gauges, or battery voltage monitoring without an external converter.
64-TFBGA — board assembly and footprint considerations
Surface-mount only — no socket option for prototyping without an adapter board.
ROHS3 compliant.
