128 KB FRAM — no erase cycles, no wear leveling needed
Its program memory is 128 KB of FRAM, a nonvolatile technology that writes at bus speed with effectively unlimited endurance — no erase-before-write, no page-program delay, and no wear-leveling scheme in the firmware. The 2K x 8 RAM handles stack and scratchpad variables; the FRAM covers everything else.
63 I/O, LCD drive, and a 12-bit ADC on a single chip
With 63 general-purpose I/O lines in the 80-LQFP package, this MCU can drive a segmented LCD panel directly, read a membrane keypad, and talk to multiple sensors without external muxing. The integrated peripherals include a 12-channel 12-bit ADC, a brown-out detect and reset circuit, a DMA controller, PWM timers, and a watchdog timer. The internal oscillator means no external crystal is required for many applications, though the clock system supports a low-frequency crystal for the RTC if the application needs tighter timekeeping. The 80-LQFP (12x12 mm) footprint is a standard 0.4 mm-pitch package that routes cleanly on a two-layer board with careful trace spacing.
