FRAM memory — no P/E cycle limits
32 KB FRAM writes at full bus speed without erase cycles; endurance is effectively unlimited. 1K x 8 SRAM handles stack and scratchpad.
End-of-life (EOL) status.
On-chip peripherals include brown-out detect, POR, DMA, PWM, and a watchdog timer — enough for a standalone controller without external supervisor ICs. Connectivity covers I²C, IrDA, SCI, SPI, and UART/USART, so the part can talk to serial sensors, displays, or a host processor over a single bus. The internal oscillator keeps the BOM count low; no external crystal needed for basic operation.
