64 KB Flash, 8 KB RAM, 24 MHz — the BOM-fit tier for 8-bit control
The core runs at 24 MHz, enough for sensor polling, communication protocol handling, and real-time I/O toggling in motor drives, user interfaces, and IoT edge nodes. An additional 256 bytes of EEPROM (256 x 8) holds calibration constants and configuration parameters that survive power cycles.
On-chip analog and serial connectivity reduce external parts
Thirteen 12-bit SAR ADC channels (A/D 13x12b SAR) and one 10-bit DAC (D/A 1x10b) are integrated, so a temperature sensor, potentiometer, or current-sense amplifier can connect directly without an external converter. The peripheral set includes Brown-out Detect/Reset, POR, PWM, and WDT — all standard for reliable standalone operation. The oscillator can be driven from an external crystal or the internal RC, saving a component when board area is tight.
