256 KB Flash, 8 KB EEPROM — memory fit for field-upgradable firmware
This memory split is sized for applications that need both a substantial firmware image and non-volatile parameter storage without external EEPROM — think motor-drive configuration tables, calibration coefficients in a sensor node, or event logs in an industrial controller.
Capacitive touch and mixed-signal peripherals
For analog front-end tasks, the part packs a 12-channel 10-bit ADC, an 8-channel 12-bit ADC, and two 8-bit DAC channels.
Package and I/O: 64-LQFP with 54 accessible GPIO
Housed in a 64-LQFP (12x12 mm body) with 54 I/O lines brought out. Surface-mount only, as expected for volume production.
Lifecycle: active, no obsolescence watch needed
No NRND or EOL notices on this order code. ROHS3 compliant per the listing.
