Product details
Overview
ST62T10CB6 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), oscillator safeguard, and low-voltage detector. It operates from 3.0V to 6.0V across –40°C to +125°C and targets embedded control in automotive body electronics, appliance motor control, and industrial sensor interfaces.
For engineers reviewing the ST62T10CB6 datasheet, ST62T10CB6 pinout, ST62T10CB6 application, or ST62T10CB6 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative options - all grounded in ST's official ST6210C documentation and package-specific ordering data.
Technical Context
The ST62T10CB6 implements a Harvard-architecture 8-bit CPU core with 40 instructions and 9 addressing modes. Its clock system supports crystal/resonator (up to 8 MHz), RC network, external clock, and backup LFAO - all monitored by Oscillator Safeguard (OSG) to prevent clock failure-induced lockup.
Interrupt handling includes 4 vectors plus NMI and RESET, servicing 12 external interrupt lines mapped across two vectors. Power management provides Wait and Stop modes, with LVD-triggered safe reset and configurable watchdog timer enabling robust operation in noisy or voltage-unstable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 8-bit ST6 Harvard CPU with 40 instructions and 9 addressing modes - enables compact firmware and deterministic timing for real-time control loops. |
| Program Memory | 2 KB OTP - user-programmable one-time, suitable for production firmware without erasure requirement or EPROM cost premium. |
| RAM Size | 64 bytes - sufficient for stack, I/O buffers, and state variables in small-scale embedded applications like fan speed control or LED dimming. |
| ADC Resolution & Channels | 8-bit, 8-channel - supports simultaneous monitoring of multiple analog sensors (e.g., temperature, voltage, potentiometer) with single-scan conversion. |
| Operating Voltage | 3.0 V to 6.0 V - compatible with 5 V logic systems and tolerant of automotive battery fluctuations (e.g., cold-crank dips). |
| Max Clock Frequency | 8 MHz - delivers ~1.25 µs instruction cycle time, adequate for sub-millisecond response in motor commutation or PWM generation. |
| Temperature Range | –40°C to +125°C - qualified for under-hood automotive, industrial PLC modules, and high-ambient consumer appliances. |
| I/O Sink Capability | 4 pins rated 20 mA - directly drives LEDs, small relays, or MOSFET gates without external buffer stages. |
Pinout & Package
ST62T10CB6 is supplied in a 20-pin plastic DIP (PDIP20) package with 0.3-inch width, compliant with JEDEC MS-001. Pin functions are validated per ST's "Pin Description" section (page 7) and block diagram (Figure 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Primary 3.0–6.0 V supply input; decoupling capacitor required near pin for noise immunity in mixed-signal operation. |
| VSS | Ground reference | Digital ground return; must be connected to system GND plane with low-impedance path to minimize reset instability. |
| OSCIN / OSCOUT | Crystal/resonator interface | Connects to parallel-resonant crystal or ceramic resonator; internal inverter enables self-oscillation without external components. |
| RESET | Asynchronous active-low reset | Pulled low to force hardware reset; internal pull-up ensures reliable startup; compatible with external RC or supervisor ICs. |
| NMI | Non-maskable interrupt | Edge-triggered input for critical fault handling (e.g., overtemperature shutdown signal) that cannot be disabled by software. |
| PA0–PA3 | Port A bidirectional I/O | 4 high-sink outputs (20 mA each); usable as PWM outputs, LED drivers, or digital control lines with strong drive capability. |
| PB0–PB7 | Port B bidirectional I/O | 8 general-purpose lines; PB0–PB3 serve as ADC input channels (Ain0–Ain3); PB4–PB7 support external interrupts. |
Key Features
| Feature | Design Value |
|---|---|
| Oscillator Safeguard (OSG) | Monitors main oscillator activity and forces safe reset if clock stops - prevents MCU hang during crystal fracture or EMI-induced oscillation loss. |
| Low Voltage Detector (LVD) | Generates reset when VDD drops below programmable threshold (typically 2.7 V or 4.0 V) - avoids erratic execution during brown-out conditions. |
| Configurable Watchdog Timer | Independent timeout circuit with software-selectable period (1 ms to 2 s) - recovers from firmware deadlock without external hardware. |
| 8-bit Timer/Counter with 7-bit Prescaler | Enables precise timing intervals (e.g., 10 ms debounce, 100 Hz PWM carrier) via scalable clock division and auto-reload capability. |
| Read-Out Protection | OTP memory lock prevents unauthorized firmware extraction - meets basic IP protection requirements for customer code deployment. |
Applications
| Automotive Body Control | 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 |
|---|---|---|---|
| ST62T20CB6 | 4 KB OTP memory, same peripherals and pinout - direct upgrade path for larger firmware. | Supports more complex control algorithms (e.g., multi-stage HVAC logic) without changing PCB layout. | Select when firmware size exceeds 2 KB or future scalability is required. |
| ST62E20C | EPROM version (erasable), identical functionality but requires UV eraser and programmer - not OTP. | Suitable only for prototyping and low-volume development due to programming infrastructure overhead. | Choose only for engineering validation where iterative code changes outweigh production cost and logistics constraints. |
Compared with ST62T20CB6, the ST62T10CB6 trades memory headroom for lower unit cost and smaller footprint; versus ST62E20C, it eliminates EPROM programming dependency while sacrificing field reprogrammability - making it optimal for cost-sensitive, high-volume embedded control.

FAQ
Is ST62T10CB6 still in active production?
ST62T10CB6 is marked as obsolete per ST's official product status documentation (Rev 4, Jan 2009). However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle coordination support, including last-time-buy planning and cross-reference guidance for migration paths.
What package variants exist for ST62T10CB6?
ST62T10CB6 is exclusively offered in the PDIP20 (plastic dual in-line package, 0.3-inch width) configuration. Other ST6210C variants include SO20 and SSOP20, but the 'B6' suffix specifically denotes the PDIP20 OTP version per ST's ordering matrix in Section 11.5.
Does ST62T10CB6 support in-circuit programming?
No - ST62T10CB6 uses one-time programmable (OTP) memory and lacks on-chip debug interfaces or serial programming capability. Firmware must be programmed prior to soldering using ST's dedicated OTP programmers (e.g., STVP with appropriate socket adapter).
Can the ADC operate during STOP mode?
No - the ADC requires the main clock domain and is disabled in STOP mode. However, the device supports Wake-up-from-STOP via external interrupt or LVD event, allowing rapid transition to RUN mode for a single ADC conversion before returning to low-power state.
