50 MHz Cortex-M3 with 256 KB Flash in a 108-BGA
The 108-ball BGA package (10x10 mm) keeps the footprint compact for space-constrained industrial or motor-control boards. On-chip peripherals include a 10-bit ADC with 8 channels, PWM timers, and a quadrature encoder interface (QEI) for position feedback.
Obsolete — sourcing via independent distribution
The 108-BGA package has a 0.8 mm ball pitch — a standard PCB process handles it, but the BGA rework profile needs care; the 10x10 mm body has moderate thermal mass, so preheat the board to 100°C before hot-air removal to avoid pad lift.
