Product details
Overview
ST62T01CM6 from STMicroelectronics is an 8-bit OTP microcontroller with 2KB program memory, 64 bytes RAM, integrated 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 datasheet, ST62T01CM6 pinout, ST62T01CM6 application, or ST62T01CM6 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed functional alternatives - all grounded in ST's official Doc ID 4563 Rev 5 specification.
Technical Context
The ST62T01CM6 implements a Harvard-architecture 8-bit CPU core with 40 instructions and 9 addressing modes. Its clock system integrates a main oscillator with Oscillator Safeguard (OSG) for fail-safe startup and a Low-Frequency Auxiliary Oscillator (LFAO) for Stop-mode wake-up.
Interrupt handling supports 4 vectors plus NMI and RESET, with 9 external interrupt lines mapped across two vectors. The peripheral set includes an 8-bit timer/counter with 7-bit prescaler, configurable watchdog timer, and 8-bit ADC with sample-and-hold and 4 dedicated analog input channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 8-bit ST6 Harvard architecture with 40 instructions and 9 addressing modes |
| Program Memory | 2KB OTP ROM - non-volatile, user-programmable during production, read-out protected |
| RAM Size | 64 bytes - sufficient for register banking and small data buffers in sensor polling loops |
| ADC Resolution & Inputs | 8-bit SAR ADC with 4 analog input channels - enables simultaneous voltage/current sensing in motor control feedback |
| Operating Voltage | 3.0V to 6.0V - compatible with 5V industrial bus systems and battery-backed 3.3V subsystems |
| Max Clock Frequency | 8 MHz - supports real-time response ≤125 ns per instruction cycle at full speed |
| Power Modes | Wait and Stop modes - Stop mode draws ≤1 µA, enabling multi-year battery operation in remote sensors |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive and factory-floor industrial environments |
Pinout & Package
ST62T01CM6 is supplied in a 16-pin SOIC (SO16) package with 1.27 mm pitch, JEDEC MS-012AC compliant, and 10.2 mm × 7.5 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply voltage input | Primary power rail (3.0–6.0 V); decoupling capacitor required within 10 mm for noise immunity |
| VSS | Ground reference | Digital ground return path; must be connected to system GND plane with low-inductance trace |
| OSCIN / OSCOUT | Crystal/resonator interface | Connects to external 32 kHz–8 MHz crystal or ceramic resonator; internal feedback resistor enabled |
| RESET | Active-low reset input | Asynchronous, Schmitt-triggered; initiates safe hardware reset on falling edge; internal pull-up active |
| NMI | Non-maskable interrupt input | Edge-triggered, used for critical fault signaling (e.g., overtemperature, overcurrent) requiring immediate ISR entry |
| PA0–PA3 | Bidirectional I/O with analog capability | PA0–PA3 support digital I/O and ADC inputs; PA1–PA3 provide 20 mA sink capability for LED/drivers |
| PB0–PB7 | General-purpose I/O | PB0–PB1 are multifunctional; PB3, PB5–PB7 serve as ADC inputs on ST62T01C variant per device summary |
Key Features
| Feature | Design Value |
|---|---|
| Oscillator Safeguard (OSG) | Detects crystal failure within 256 clock cycles and forces safe reset - prevents runaway operation in safety-critical timing paths |
| Low Voltage Detector (LVD) | Monitors VDD and asserts reset below 2.5 V (typ.) - ensures deterministic state retention during brownout |
| High-Sink I/O Lines | PA1–PA3 deliver 20 mA sink current each - directly drive LEDs, relays, or small solenoids without external drivers |
| Backup LFAO Clock | Internal 32 kHz RC oscillator remains active in Stop mode - enables timed wake-up every 16–512 ms for periodic sensor sampling |
| Read-Out Protection | Hardware-enforced lock on program memory - prevents unauthorized firmware extraction via probe or debugger |
Applications

Use Value: Single-chip solution replaces discrete comparator + microcontroller + ADC combo, cutting PCB area by 40%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST62T00CM6 | 1 KB OTP program memory (vs. 2 KB), identical peripherals and pinout | Suitable for simpler firmware with <1 KB code footprint; same ADC/timer features retained | Select when firmware size is confirmed ≤1 KB to reduce cost without sacrificing functionality |
| ST62T20CM6 | Includes UART interface and 128 bytes RAM (vs. 64 bytes); same 2 KB OTP and ADC | Required for host communication (e.g., RS-232 diagnostics, firmware updates) not supported by ST62T01C | Choose only if serial connectivity is mandatory; adds UART overhead but no pinout change |
Compared with ST62T01CM6, ST62T00CM6 reduces memory capacity without altering I/O or analog capability - ideal for cost-sensitive volume production - while ST62T20CM6 adds UART and RAM at the expense of higher unit cost and unchanged package compatibility.

FAQ
Is ST62T01CM6 pin-compatible with ST62T00CM6?
Yes - both devices share identical 16-pin SOIC (SO16) packaging and pin mapping per Section 2 of Doc ID 4563 Rev 5. The only functional difference is program memory size (2 KB vs. 1 KB), making them drop-in replacements where code fits within 1 KB.
Does ST62T01CM6 support in-circuit programming after soldering?
No - ST62T01CM6 uses One-Time-Programmable (OTP) memory. Programming must occur prior to board assembly using ST's ST62xx EPROM programmers (e.g., ST62xx-PROG) and verified with checksum before placement.
What is the maximum ADC sampling rate achievable?
The 8-bit ADC achieves up to 15 kSPS under optimal conditions: VDD = 5 V, internal RC clock, and single-channel conversion. Conversion time is 72 µs minimum per sample, limited by internal RC timing and reference settling.
Can the watchdog timer be disabled in software?
No - the watchdog timer is permanently enabled after power-on reset. It can only be serviced via WDG register write; failure to refresh within timeout (programmable from 16 ms to 2 s) triggers hardware reset - a safety feature per ST62xx design.
