ST62T55C/E65C is an 8-bit microcontroller launched by ST company, which has A/D converter, safe reset, auto-reload timer, EEPROM and SPI, with a power supply voltage range of 3.0-6.0V, a maximum clock frequency of 8MHz and a working temperature range of -40 to +125°C.
The ST62T55C, ST62T65C and ST62E65C are low‑cost 8‑bit HC‑MOS microcontrollers from the ST62xx family, aimed at automotive, appliance and industrial applications. They provide a common core with a variety of on‑chip peripherals and are available in several PDIP, PSO and SSOP packages.
Key on‑chip features include a 13‑channel 8‑bit A/D converter, 8‑bit synchronous SPI interface, digital watchdog, oscillator safeguard, low‑voltage detector, an 8‑bit timer, an 8‑bit auto‑reload timer, and up to 128 bytes of EEPROM (absent on the ST62T55C). The devices support 21 fully programmable I/O pins that can be configured as inputs, outputs, analog inputs or open‑drain/push‑pull lines, with up to 30 mA sink capability for LEDs or TRIACs.
