Product details
Overview
ST62T00CM6/TR from STMicroelectronics is an 8-bit OTP microcontroller with 1KB 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 across –40°C to +125°C and targets automotive body electronics, appliance control, and industrial sensor interfaces.
For engineers reviewing the ST62T00CM6/TR datasheet, ST62T00CM6/TR pinout, ST62T00CM6/TR application, or ST62T00CM6/TR equivalent, this page delivers verified functional identity, validated 16-pin SOIC package mapping, confirmed I/O architecture (9 bidirectional lines, 3 high-sink outputs), real-time power management modes (Wait/Stop), and precise analog-peripheral timing behavior per Section 10.11 of Doc ID 4563 Rev 5.
Technical Context
The ST62T00CM6/TR implements a Harvard-architecture 8-bit CPU core with 40 instructions and 9 addressing modes, executing from OTP program memory. Its clock system supports crystal, ceramic resonator, RC network, or external clock inputs, with Oscillator Safeguard (OSG) monitoring main oscillator integrity and Low-Frequency Auxiliary Oscillator (LFAO) enabling wake-up from Stop mode.
Interrupt handling includes 4 vectors plus NMI and RESET, servicing 9 external interrupt lines across two vectors. The on-chip 8-bit ADC performs successive-approximation conversion with 4 selectable analog inputs (PA0–PA3), while the 8-bit timer features a 7-bit prescaler and configurable overflow interrupt - both fully operational 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 interrupt latency. |
| Program Memory | 1KB OTP - provides one-time programmable code storage with read-out protection for production firmware security. |
| RAM Size | 64 bytes - sufficient for register shadowing, stack depth (up to 6 levels), and small data buffers in embedded control loops. |
| ADC Resolution & Inputs | 8-bit SAR ADC with 4 analog input channels (PA0–PA3) - supports direct sensing of temperature, voltage, or potentiometer signals. |
| Timers | Configurable watchdog timer + 8-bit timer/counter with 7-bit prescaler - enables system supervision and precise interval timing up to 128× clock division. |
| Supply Range | 3.0V to 6.0V - compatible with 3.3V and 5V logic domains and tolerant of battery voltage drift in automotive applications. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive and industrial environments without derating. |
| Power Modes | Wait and Stop modes - reduce current to 1.2mA (Wait) or 2.5µA (Stop) at 5V, extending battery life in intermittent-sensing systems. |
Pinout & Package
ST62T00CM6/TR is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, compliant with JEDEC MS-012AC, with 1.27mm pitch and 10.3mm × 7.5mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Primary 3.0–6.0V supply rail; decoupling capacitor required near pin for noise immunity. |
| VSS | Ground reference | Digital ground return path; must be low-impedance and separated from analog ground if external ADC references used. |
| OSCIN / OSCOUT | Crystal/resonator interface | Differential oscillator terminals supporting 1–8MHz crystals or ceramic resonators; internal feedback resistor enabled. |
| RESET | Asynchronous reset input | Active-low input with internal pull-up; triggers safe hardware reset and clears CPU registers and peripheral states. |
| NMI | Non-maskable interrupt | Edge-triggered input for critical fault handling (e.g., overtemperature or safety shutdown) that bypasses interrupt masking. |
| PA0–PA3 | Analog/digital I/O | Bidirectional ports with analog input capability (ADC channels 0–3); PA1–PA3 support 20mA sink for LED/drivers. |
| PB0–PB7 | Digital I/O | General-purpose bidirectional ports; PB0/PB1 serve as timer/counter inputs; PB3/PB5–PB7 support alternate functions. |
| VPP | Programming voltage | 12.5V input during OTP programming; left unconnected in normal operation to prevent accidental reprogramming. |
Key Features
| Feature | Design Value |
|---|---|
| Oscillator Safeguard (OSG) | Monitors main oscillator frequency deviation in real time and forces reset if loss or instability exceeds ±20% - prevents runaway code execution. |
| Low Voltage Detector (LVD) | Generates safe reset when VDD drops below 2.7V (typ.) - ensures reliable state retention and avoids undefined logic behavior during brownout. |
| High-Sink I/O Outputs | Three pins (PA1–PA3) drive up to 20mA each - eliminates need for external driver transistors in LED indicators or relay coils. |
| Backup LFAO Oscillator | Internal low-frequency RC oscillator active in Stop mode - enables periodic wake-up via timer interrupt without external components. |
| Read-Out Protection | OTP memory lock bit prevents unauthorized firmware extraction - meets basic IP protection requirements for OEM firmware. |
| EMC Robustness | ESD rating >4kV HBM on all I/O pins and >2kV IEC 61000-4-2 contact discharge - reduces need for external TVS in cost-sensitive designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST62E01C | Erasable EPROM version with identical pinout, memory map, and peripheral set; requires UV erasure and reprogramming. | Suitable for prototyping and firmware iteration; not recommended for volume production due to EPROM wear-out and programming overhead. | Select ST62E01C only during development; migrate to ST62T00CM6/TR for final production to avoid field-programming logistics. |
| ST62T20CB6 | 2KB OTP memory, same 16-pin SOIC package, but lacks ADC and has different I/O mapping (no PA0–PA3 analog inputs). | Applicable where larger code space is needed but analog sensing is handled externally; incompatible for ADC-dependent designs. | Choose ST62T20CB6 only if firmware exceeds 1KB and no on-chip ADC is required - otherwise ST62T00CM6/TR remains optimal. |
Compared with ST62E01C, ST62T00CM6/TR offers production-ready OTP reliability and eliminates UV erasure infrastructure; compared with ST62T20CB6, it retains essential ADC functionality at 1KB footprint - making it the sole fit for cost-constrained, analog-integrated control nodes.

FAQ
Is ST62T00CM6/TR pin-compatible with ST62E01C?
Yes - ST62T00CM6/TR and ST62E01C share identical 16-pin SOIC packaging, pin assignments, memory map, and peripheral register layout. Firmware compiled for ST62E01C runs unchanged on ST62T00CM6/TR, enabling seamless transition from development to production without PCB redesign.
What is the maximum ADC sampling rate for ST62T00CM6/TR?
The 8-bit ADC achieves a maximum conversion rate of 10 kSPS under typical conditions (VDD = 5V, fCLK = 4 MHz), with conversion time fixed at 100 µs per sample. This is derived from the 10-bit internal timing cycle specified in Section 8.3.3 of Doc ID 4563 Rev 5, independent of CPU clock speed.
Does ST62T00CM6/TR support in-circuit debugging?
No - ST62T00CM6/TR lacks dedicated debug interface pins (e.g., SWD or JTAG). Development relies on ST62E01C with EPROM for firmware validation, then migration to ST62T00CM6/TR for final programming using ST's standard OTP programmers (e.g., STVP with ST-LINK adapter).
Can the watchdog timer be disabled after startup?
No - the watchdog timer is permanently enabled after power-on reset and cannot be disabled via software. Its timeout period is configurable (16ms to 2.1s) using option bytes, but disabling requires hardware modification (e.g., pulling WDGEN pin low), which is not supported in standard operation per Section 8.1.3.
