50 MHz Cortex-M3 with 64 KB Flash – what it handles
With 64 KB of on-chip Flash and 16 KB SRAM, it fits control applications that need moderate code space and a small data buffer — think motor commutation loops, sensor fusion, or protocol bridging. The 43 general-purpose I/O pins and built-in peripherals — including I²C, SPI, UART, PWM, and a 4-channel 10-bit ADC — let it interface directly with sensors, actuators, and serial buses without external glue logic.
The supply voltage range of 2.25 V to 2.75 V means a single 2.5 V rail or a tightly regulated 2.5 V LDO powers the core and I/O banks, simplifying the power tree.
For BOM lines that still require this part, procurement must go through independent distribution or the open market. We source and quote to order against your quantity — confirm the package (100-LQFP, Tape & Reel) and temperature grade match your assembly profile before committing.
