Product details
Overview
ST62T10CM6 from STMicroelectronics is an 8-bit OTP microcontroller with 2KB program memory, 64 bytes RAM, integrated 8-bit ADC (8-channel), dual timers (including watchdog), and oscillator safeguard. It operates from 3.0V to 6.0V across –40°C to +125°C and targets automotive body electronics, industrial sensor interfaces, and appliance control where safe reset, low-power operation, and analog sensing are required.
For engineers reviewing the ST62T10CM6 datasheet, ST62T10CM6 pinout, ST62T10CM6 application, or ST62T10CM6 equivalent, key selection criteria include its LVD-enabled safe reset, 20mA high-sink I/O capability, OSG-protected clock system, and support for Wait/Stop power-saving modes in harsh environments.
Technical Context
The ST62T10CM6 implements a Harvard-architecture 8-bit CPU core with 40 instructions and 9 addressing modes. Its clock system supports crystal, RC, or external clock inputs, backed by Oscillator Safeguard (OSG) to detect and recover from clock failure and a Low-Frequency Auxiliary Oscillator (LFAO) for Stop mode wake-up.
Interrupt handling includes 4 vectors plus NMI and RESET, servicing 12 external lines across two vectors. The on-chip 8-bit ADC features programmable acquisition time and conversion trigger sources, while the 8-bit timer includes a 7-bit prescaler and interrupt capability - both fully functional in Wait mode but halted in Stop mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 8-bit Harvard CPU with 40 instructions and 9 addressing modes - enables compact firmware and deterministic timing for real-time control loops. |
| Program Memory | 2KB OTP - provides one-time programmable, tamper-resistant code storage suitable for production firmware without reprogramming risk. |
| RAM Size | 64 bytes - sufficient for stack, registers, and small variable sets in resource-constrained embedded applications. |
| ADC Resolution & Channels | 8-bit, 8-channel - supports simultaneous monitoring of multiple analog sensors (e.g., temperature, voltage, potentiometer) with single-cycle sampling control. |
| Operating Voltage | 3.0V to 6.0V - accommodates wide-input automotive and industrial power rails without external regulation. |
| Temperature Range | –40°C to +125°C - qualified for under-hood automotive and industrial motor-control environments. |
| Power Modes | Wait and Stop - reduces current to 1.2mA (Wait) or 1.5µA (Stop) at 5V, enabling battery-backed or energy-harvested operation. |
| Reset Protection | Low Voltage Detector (LVD) + Oscillator Safeguard (OSG) - ensures reliable reset during brown-out or clock fault, critical for safety-critical functions. |
Pinout & Package
ST62T10CM6 is housed in a 20-pin SOIC (SO20) package with 12 multifunctional I/O lines, including 4 high-sink outputs rated for 20mA. Pin functions are validated per STMicroelectronics' "Pin Description" section (page 7, Rev 4 datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power Supply | Primary 3.0–6.0V supply input; decoupling required near pin for noise immunity in noisy automotive/industrial settings. |
| VSS | Ground Reference | Digital ground return; must be low-impedance and separated from analog ground if ADC precision is critical. |
| OSCIN / OSCOUT | Crystal Oscillator Interface | Connects to external crystal/resonator (up to 8MHz); OSG monitors oscillation integrity and forces reset on failure. |
| RESET | Asynchronous Active-Low Reset | Hardware reset input with internal pull-up; accepts external debounced signal or LVD-triggered assertion. |
| NMI | Non-Maskable Interrupt | Edge-triggered input for critical event handling (e.g., emergency stop) that bypasses interrupt masking logic. |
| PA0–PA3 | Port A I/O Lines | Bidirectional with 20mA sink capability - drive LEDs, relays, or logic-level MOSFET gates directly without external buffers. |
| PB0–PB7 | Port B I/O Lines | Includes 8 analog input channels (Ain0–Ain7) for ADC; configured as digital I/O or analog input via software register. |
Key Features
| Feature | Design Value |
|---|---|
| Oscillator Safeguard (OSG) | Monitors main oscillator activity in real time and triggers hardware reset within 4ms if oscillation stops - prevents runaway code execution due to clock failure. |
| Low Voltage Detector (LVD) | Configurable trip point (typically 2.7V or 3.8V) with hysteresis; asserts reset before supply collapse compromises register state or memory integrity. |
| High-Sink I/O (PA0–PA3) | 20mA per pin sink current - eliminates need for external driver transistors when interfacing with indicators or small solenoids. |
| 8-Bit Timer with Prescaler | 7-bit programmable prescaler enables precise timing intervals from µs to seconds using 8-bit counter - ideal for PWM generation or periodic polling. |
| Watchdog Timer | Configurable timeout (16ms to 2.1s) with windowed refresh option - detects software hangs and recovers system autonomously. |
| ADC Acquisition Control | Software-selectable sample-and-hold time (1–64 clock cycles) and trigger source (timer overflow, software, external edge) - optimizes resolution vs. speed trade-off per channel. |
Applications
| Automotive Body Control Module | Industrial Temperature Monitor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST62T20CM6 | 4KB OTP, same peripherals and package - larger code space for complex control algorithms or bootloader integration. | Used where firmware size exceeds 2KB or future feature expansion is anticipated. | Select when >2KB application code is required; pin- and register-compatible, requiring only recompilation. |
| ST62E20C | 2KB EPROM (erasable UV), identical architecture and peripherals - enables iterative development and field firmware updates. | Preferred during prototyping or low-volume production where code revision is frequent. | Choose for design validation phase; requires UV eraser and programming socket - not suitable for final production. |
Compared with ST62T10CM6, ST62T20CM6 offers scalable code density without peripheral or timing changes, while ST62E20C trades OTP permanence for development flexibility - both share identical I/O, ADC, and power management behavior.

FAQ
Is ST62T10CM6 still in active production?
No - ST62T10CM6 is marked obsolete by STMicroelectronics (as noted in the January 2009 Rev 4 datasheet title page). However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for drop-in replacements and migration paths to active STMicroelectronics alternatives such as the STM8S series.
What clock sources does ST62T10CM6 support?
ST62T10CM6 supports three clock sources: external crystal or ceramic resonator (up to 8MHz), RC network (internal or external), and external clock signal applied to OSCIN. The Low-Frequency Auxiliary Oscillator (LFAO) provides a 32kHz backup clock for Stop mode wake-up and RTC-like timing.
Can the ADC operate during Stop mode?
No - the ADC is disabled in Stop mode. It remains fully operational in Run and Wait modes. In Wait mode, the ADC can perform conversions triggered by software or timer overflow, with typical conversion time of 100µs at 4MHz CPU clock. Wake-up from Stop mode requires external interrupt or LFAO event before ADC use.
Does ST62T10CM6 support in-circuit programming?
No - ST62T10CM6 uses One-Time Programmable (OTP) memory and lacks on-chip debug interfaces or serial programming capability. Programming occurs once during manufacturing using dedicated OTP programmers. Development is typically done with the pin-compatible ST62E20C (EPROM version), which supports UV erasure and reprogramming.
