Product details
Overview
ST62T01CM6/TR from STMicroelectronics is an 8-bit OTP microcontroller with 2KB program memory, 64 bytes RAM, 8-bit ADC (4-channel), dual timers (including watchdog), oscillator safeguard, and low-voltage detector. It operates from 3.0V to 6.0V, supports crystal/RC/LFAO clock sources, and targets embedded control in automotive sensors and industrial monitoring systems.
For engineers reviewing the ST62T01CM6/TR datasheet, ST62T01CM6/TR pinout, ST62T01CM6/TR application, or ST62T01CM6/TR equivalent, key selection criteria include OTP programmability, 20mA high-sink I/O capability, integrated LVD reset, STOP/WAIT power modes, and compatibility with ST62E01C for development.
Technical Context
The ST62T01CM6/TR implements a Harvard-architecture 8-bit CPU core with 40 instructions and 9 addressing modes. Its on-chip peripherals include an 8-bit timer/counter with 7-bit prescaler, configurable watchdog timer, and 8-bit successive-approximation ADC with four analog input channels mapped to Port A pins.
Reset management combines asynchronous RESET pin assertion, LVD-triggered safe reset, and watchdog timeout. Clock system integrates main oscillator (up to 8MHz), backup LFAO, and Oscillator Safeguard (OSG) to detect and recover from crystal failure - critical for automotive and industrial reliability.

FAQ
Is ST62T01CM6/TR pin-compatible with ST62E01C?
Yes. ST62T01CM6/TR and ST62E01C share identical 16-pin SOIC packaging, pin assignments, and electrical characteristics. They differ only in memory technology (OTP vs. EPROM), making them hardware-compatible for both PCB layout and signal routing.
What clock sources does ST62T01CM6/TR support?
ST62T01CM6/TR supports four clock sources: external crystal/ceramic resonator (1–8MHz), RC network, external clock input, and low-frequency auxiliary oscillator (LFAO). The OSG circuit validates main oscillator integrity and triggers reset on failure.
Does ST62T01CM6/TR include a hardware watchdog timer?
Yes. It features a configurable digital watchdog timer with timeout periods selectable via option bytes. Watchdog reset is independent of main clock and remains active in WAIT mode, providing deterministic fault recovery.
Can ST62T01CM6/TR operate down to 3.0V with full functionality?
Yes. All specifications - including 8MHz max frequency, ADC accuracy, and 20mA I/O sink - are guaranteed over the full 3.0V to 6.0V supply range. The integrated LVD asserts reset below 2.5V (typ.) to prevent undefined operation.
