8 MHz core — enough for sensor polling and display updates
8 MHz clock rate is modest by today's MCU standards, but it's well matched to the 16-bit RISC pipeline and the typical application loop: wake from low-power mode, sample a few ADC channels, update the LCD segment data, and go back to sleep.
On-chip analog: 5x16-bit ADC and 2x12-bit DAC
The 5-channel 16-bit sigma-delta ADC is the standout feature — it gives you enough resolution for precision sensor bridges without an external converter. The two 12-bit DACs can drive an analog output or a reference for a comparator. If your design needs more than five analog inputs, you'll need an external mux, but for a typical three-sensor flow meter with a display, this covers it.
Lifecycle: marked end-of-life — source through surplus
Connectivity and I/O
The part provides I²C, SPI, UART/USART, IrDA, LINbus, and SCI interfaces — a full set for industrial sensor buses and simple wired links. With 48 general-purpose I/O pins in the 80-LQFP package, you have enough headroom for a keypad, a few LEDs, and the display bus without needing a port expander.
Temperature range and supply
Rated for -40°C to 85°C ambient, this MCU suits indoor and outdoor instrumentation enclosures — not under-hood automotive, but fine for a weather station or a solar-powered flow meter. The supply range of 1.8 V to 3.6 V lets it run from two alkaline cells or a single Li-ion cell without a regulator.
