Low-power Cortex-M0+ in a 14-pin TSSOP — what the specs mean for your BOM
It packs 8 KB of Flash program memory, 2 KB of SRAM, and 512 bytes of EEPROM in a compact 14-TSSOP package.
Memory sizing — 8 KB Flash, 2 KB SRAM, 512 B EEPROM
With 8 KB of Flash and 2 KB of SRAM, this MCU targets sensor-node firmware, simple control loops, and protocol bridges where the code fits in a few thousand instructions. The 512 bytes of EEPROM, mapped into the memory map, stores calibration constants and configuration data without needing an external serial EEPROM — a BOM simplification for cost-sensitive designs.
Peripherals and I/O — 11 GPIOs, I²C, SPI, UART, 4-channel 12-bit ADC
The 4-channel 12-bit ADC handles analog inputs like temperature, pressure, or battery voltage. Built-in brown-out detect, POR, PWM, and watchdog peripherals reduce external supervisory ICs.
