16 MHz core, 2 KB flash — the field-swap workhorse
The 20-TSSOP package is hand-solderable with a fine-tip iron — no hot-air station needed for a field swap. On-chip peripherals include a 10-bit ADC with 8 channels, I²C/SPI/USI serial connectivity, and a brown-out detect/reset, POR, PWM, and watchdog timer.
Industrial temperature grade — outdoor and factory-floor ready
The 16 I/O pins, each with interrupt capability, are enough for a keypad, a few sensors, and a small display — common in thermostat and flow-meter designs.
For a production BOM line that has been running for years, this part is not the one forcing a redesign.
This is a current-production, ROHS3-compliant device. No stock count or lead-time number here — those move daily — but the active status means the supply chain is open, not a broker-only scavenger hunt.
