Product details
Overview
ST62T00CB6 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 ST62T00CB6 datasheet, ST62T00CB6 pinout, ST62T00CB6 application, or ST62T00CB6 equivalent, key selection considerations include its 16-pin SO package, 8MHz max clock, 3 high-sink I/Os (20mA), Wait/Stop power modes, and LVD-enabled safe reset behavior in voltage-critical environments.
Technical Context
The ST62T00CB6 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, plus a backup LFAO and Oscillator Safeguard (OSG) to detect and recover from clock failure.
Interrupt handling includes 4 vectors plus NMI and RESET, servicing 9 external lines mapped across two vectors. The on-chip 8-bit ADC features 4 analog input channels with programmable conversion timing, while the 8-bit timer includes a 7-bit prescaler for flexible event counting and timing intervals.
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 | 1KB OTP - provides one-time programmable, tamper-resistant code storage without need for external EPROM programmers. |
| RAM Size | 64 bytes - sufficient for small state machines and sensor data buffering in resource-constrained embedded systems. |
| ADC Resolution & Channels | 8-bit, 4-channel - supports direct analog sensing of temperature, voltage, or potentiometer signals without external signal conditioning. |
| Max Clock Frequency | 8 MHz - delivers adequate throughput for motor control, LED dimming, and serial communication at low power. |
| Supply Voltage Range | 3.0 V to 6.0 V - compatible with 3.3V and 5V logic domains and tolerant of battery voltage sag in automotive applications. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial environments requiring extended thermal reliability. |
Pinout & Package
ST62T00CB6 is housed in a 16-pin Small Outline (SO16) package with 1.27 mm pitch, JEDEC MS-012AC compliant, suitable for automated SMT assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Primary 3.0–6.0 V supply rail; decoupling capacitor required near pin for noise immunity during ADC/timer operation. |
| VSS | Ground reference | Digital ground return path; must be low-impedance and separated from analog ground if external sensors are used. |
| OSCIN / OSCOUT | Crystal/resonator interface | Connects to external 32.768 kHz or 1–8 MHz crystal; OSG monitors oscillation stability and triggers reset on failure. |
| RESET | Active-low reset input | Asynchronous, Schmitt-triggered input; driven low by internal LVD or external circuit to force safe initialization. |
| NMI | Non-maskable interrupt | Edge-triggered input for critical fault handling (e.g., overtemperature, safety shutdown) that cannot be disabled by software. |
| PA0–PA3 | Port A bidirectional I/O | PA1–PA3 support 20 mA sink capability - drive LEDs, relays, or low-side switches directly without external drivers. |
| PB0–PB7 | Port B bidirectional I/O | Includes PB0/PB1 as alternate-function timer/ADC pins; PB3, PB5–PB7 serve as analog inputs (Ain0–Ain3) when configured. |
Key Features
| Feature | Design Value |
|---|---|
| Oscillator Safeguard (OSG) | Hardware monitor detects crystal stoppage or frequency deviation and forces reset - eliminates risk of silent MCU hang in safety-critical systems. |
| Low Voltage Detector (LVD) | Configurable threshold (typically 2.5 V or 3.8 V) triggers safe reset before supply collapse corrupts RAM or EEPROM - prevents erratic behavior during brownout. |
| High-Sink I/O Outputs | Three pins (PA1–PA3) deliver 20 mA sink current - directly drive indicators or small solenoids without discrete transistors or driver ICs. |
| Power Saving Modes | Wait mode halts CPU but retains RAM and peripheral clocks; Stop mode disables all clocks except LFAO - extends battery life in intermittent-sensing applications. |
| On-Chip Watchdog Timer | Configurable timeout (1 ms to 2 s) with windowed refresh option - ensures firmware liveness and recovers from infinite loops or lockups. |
Applications
| Automotive Body Control | Smart Appliance Interface |
|---|---|
Use Scenario: Controlling door locks, interior lighting, and window lift motors in 12V vehicle electrical systems. IC Role / Device Role / Timing Role: Central MCU managing PWM-driven motor control, switch debouncing, and LIN bus communication timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST62T20CB6 | 2KB OTP memory, same peripherals and pinout - adds code space for larger firmware with communication stacks or calibration tables. | Preferred where bootloader, OTA update capability, or multi-sensor fusion logic requires >1KB flash. | Select when future firmware expansion is anticipated; identical footprint and toolchain compatibility reduce redesign effort. |
| STM8S003F3P6 | Enhanced 8-bit core, 8KB Flash, 1KB RAM, 10-bit ADC, higher clock (16 MHz), but different pinout and no OSG/LFAO. | Suitable for cost-sensitive designs needing more performance or precision, but requires PCB and firmware rework. | Choose only if migrating to STM8 ecosystem; not drop-in - lacks OSG and LVD reset integration found in ST62T00CB6. |
Compared with ST62T20CB6, ST62T00CB6 trades memory headroom for lower unit cost and smaller die size; versus STM8S003F3P6, it offers superior clock fault resilience and simpler qualification for legacy automotive platforms.

FAQ
What programming method does ST62T00CB6 support?
ST62T00CB6 uses One-Time Programmable (OTP) memory, programmed via standard ST62 development tools (e.g., STVP with ST-LINK adapter). Programming occurs once during manufacturing or final test; no in-system reprogramming capability exists. The device does not support ISP or debug wire protocols after initial programming.
Does ST62T00CB6 include hardware debug support?
No, ST62T00CB6 lacks dedicated debug interfaces like SWIM or JTAG. Development relies on ROM/EPROM variants (e.g., ST62E01C) for emulation and breakpoint debugging. Once programmed, OTP devices require functional testing only - no runtime inspection or step-through capability is available on the final part.
How does the Oscillator Safeguard (OSG) function in practice?
OSG continuously monitors the main oscillator's output frequency and amplitude. If oscillation stops or deviates beyond ±20% for >100 µs, OSG asserts a hardware reset signal independent of software control. This occurs within 2–3 clock cycles and requires no firmware configuration - it is always active after power-on.
Can ST62T00CB6 operate reliably at 3.3V supply?
Yes - ST62T00CB6 is fully specified from 3.0V to 6.0V. At 3.3V, maximum operating frequency is 5 MHz (not 8 MHz), and ADC accuracy remains within ±2 LSB per datasheet Section 10.11. All I/Os are 5V-tolerant, enabling direct interfacing with 5V peripherals even at 3.3V VDD.
