Product details
Overview
ST62T01CM3/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 LVD reset-designed for embedded control in automotive body electronics, appliance motor interfaces, and industrial sensor nodes.
For engineers reviewing the ST62T01CM3/TR datasheet, ST62T01CM3/TR pinout, ST62T01CM3/TR application, or ST62T01CM3/TR equivalent, this page delivers verified electrical specs, I/O configuration, power management modes, real-world use cases, and validated alternative parts for design-in and BOM optimization.
Technical Context
The ST62T01CM3/TR implements an HCMOS 8-bit CPU core with 40 instructions and 9 addressing modes, supporting bit manipulation and direct peripheral register access. Its clock system integrates main oscillator (crystal/RC/external), low-frequency auxiliary oscillator (LFAO), and oscillator safeguard (OSG) for fail-safe timing.
Reset architecture includes asynchronous RESET pin, NMI, watchdog timeout, and LVD-triggered safe reset across 3.0–6.0 V supply range. Power management provides Wait and Stop modes with wake-up via interrupt or external event-enabling sub-10 µA standby current at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 8-bit HCMOS CPU with 40 instructions and 9 addressing modes-enables compact firmware and deterministic real-time response. |
| Program Memory | 2 KB OTP-supports field-programmable firmware without erasure equipment; read-out protection prevents IP leakage. |
| RAM Size | 64 bytes-sufficient for stack, variables, and I/O buffering in small-scale control loops. |
| ADC Resolution & Channels | 8-bit, 4-channel analog-to-digital converter-measures temperature, voltage, or potentiometer signals directly. |
| Timers | One 8-bit timer/counter with 7-bit prescaler + independent watchdog timer-supports PWM generation and system reliability monitoring. |
| Supply Voltage Range | 3.0 V to 6.0 V-compatible with 5 V legacy systems and battery-powered 3.3 V designs with margin. |
| Operating Temperature | −40 °C to +125 °C-qualified for under-hood automotive and industrial environments. |
| I/O Sink Capability | Three high-sink outputs rated at 20 mA each-directly drives LEDs, relays, or small solenoids without external drivers. |
Pinout & Package
ST62T01CM3/TR is housed in a 16-pin SOIC (SO16) package with 1.27 mm pitch, RoHS-compliant, and rated for industrial temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Primary 3.0–6.0 V 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 ADC used. |
| OSCIN / OSCOUT | Crystal/resonator interface | Connects to external crystal (1–8 MHz) or RC network; OSG monitors oscillation integrity. |
| RESET | Active-low reset input | Asynchronous, Schmitt-triggered; initiates full hardware reset on falling edge or sustained low state. |
| NMI | Non-maskable interrupt input | Edge-triggered; used for critical fault detection (e.g., overtemperature, safety shutdown). |
| PA0–PA3 | Port A bidirectional I/O | PA1–PA3 support 20 mA sink; PA0 may serve as ADC input or general-purpose I/O. |
| PB0–PB7 | Port B bidirectional I/O | PB0/PB1 are alternate-function capable; PB3, PB5–PB7 support analog input (ADC channels). |
| VPP | Programming voltage input | Required only during OTP programming (12.5 V); left unconnected in normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Oscillator Safeguard (OSG) | Detects crystal failure or stoppage and forces safe reset-prevents runaway execution in timing-critical systems. |
| Low Voltage Detector (LVD) | Monitors VDD and triggers reset below programmable threshold (typically 2.7 V)-avoids undefined logic states during brownout. |
| Two Power-Saving Modes | Wait mode halts CPU while peripherals remain active; Stop mode disables all clocks except LFAO-reduces current to ≤10 µA. |
| 4-Channel 8-bit ADC | Single-ended conversion with internal reference; supports polling or interrupt-driven sampling for sensor interfacing. |
| 9 Multifunction I/O Lines | Includes 4 alternate-function pins (e.g., timer input/output, ADC inputs) and 3 high-current sink outputs-minimizes external components. |
| Watchdog Timer | Configurable timeout period; requires periodic service to prevent system lockup-essential for unattended operation. |
Applications
| Automotive Body Control | Home Appliance Motor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST62T00CM3/TR | 1 KB OTP memory, same package and pinout-lacks 1 KB of program space. | Suitable for simpler firmware with ≤1 KB code footprint; identical peripheral set and timing behavior. | Select when firmware size is confirmed under 1 KB and cost sensitivity outweighs future scalability. |
| ST62E01CM3 | 2 KB EPROM (erasable), requires UV eraser; otherwise functionally identical. | Used in development phase for iterative testing before OTP mask finalization. | Choose for prototyping where frequent code updates are needed prior to production OTP commitment. |
Compared with ST62T01CM3/TR, ST62T00CM3/TR trades program memory for lower unit cost in constrained-code applications, while ST62E01CM3 enables rapid firmware iteration but adds erasure infrastructure overhead and longer production lead time.

FAQ
What programming voltage is required for ST62T01CM3/TR?
The ST62T01CM3/TR requires 12.5 V applied to the VPP pin during OTP programming. This voltage is not needed during normal operation-VPP must be left unconnected or tied to VSS in run mode to avoid latch-up or damage.
Does ST62T01CM3/TR support in-circuit debugging?
No-the ST62T01CM3/TR lacks on-chip debug interface (e.g., SWD/JTAG). Development relies on ST62E01CM3 (EPROM version) with compatible programmers like STVP or third-party tools supporting ST6 legacy protocols.
Can the ADC operate during Stop mode?
No-the ADC is disabled in Stop mode as all clocks except LFAO are halted. It resumes operation upon wake-up in Run or Wait mode; for ultra-low-power sensing, use external comparator + interrupt wake-up instead.
Is the ST62T01CM3/TR RoHS compliant?
Yes-ST62T01CM3/TR is manufactured in accordance with RoHS Directive 2011/65/EU. The SO16 package uses lead-free terminations and complies with JEDEC J-STD-020 moisture sensitivity level MSL3.
