ST6252C ST6262B ST6262C 8-bit MCUs with A/D converter, safe reset, auto-reload timer and EEPROM
This document is a technical datasheet for the ST6252C, ST6262B, and ST6262C 8-bit microcontrollers (MCUs). These devices are low-cost members of the ST62xx HCMOS family, designed for low to medium complexity applications in automotive, appliance, and industrial sectors. The MCUs feature a common core surrounded by on-chip peripherals including an 8-bit A/D converter, EEPROM (except in ST6252C), and a digital watchdog timer.
