Buyers should evaluate last-time-buy quantities or identify a pin-compatible replacement for long-term supply. ## Memory and peripheral budget for a control-loop MCU The 2 KB EEPROM handles calibration constants and fault logs without external storage. ## 64-pin LQFP — layout and routing Housed in a 64-LQFP package, this MCU offers 52 I/O pins for interfacing with sensors, actuators, displays, or communication transceivers. Supply range from 3V to 5.5V lets it run on a regulated 3.3V rail or directly off an automotive battery with a simple pre-regulator.","metaTitle":"ST STM8AF6289TAY 8-bit MCU, 24 MHz, 64 KB Flash, NRND","metaDescription":"STMicroelectronics STM8AF6289TAY 8-bit MCU: 24 MHz core, 64 KB Flash, 6 KB RAM, 2 KB EEPROM, 52 I/O, -40°C to 85°C, 3V-5.5V.
