What this MCU is and where it fits
Industrial temperature and supply range
Rated from -40°C to 85°C. Supply range of 1.8 V to 3.6 V. Internal oscillator included.
Connectivity and peripherals for field I/O
I²C, SPI, and UART/USART interfaces cover the standard sensor and actuator links — temperature probes, digital potentiometers, serial displays. The brown-out detect and POR circuits keep the MCU from locking up during a sagging supply, which matters when the panel shares a branch circuit with a contactor coil. Watch the 2K x 8 RAM: it is tight for buffered UART streams, so plan your packet sizes accordingly.
Lifecycle and sourcing
Status is Active per the manufacturer — no end-of-life notice, no last-time-buy clock ticking. That means you can spec it into a new BOM without worrying about a forced redesign next year. We source and quote this part to order against an RFQ; availability and current pricing are confirmed at quote time. No pin-compatible second source is listed in the official cross-reference, so dual-sourcing would require a board respin.
