Description and Introduction

8-BIT OTP/EPROM MCUs WITH A/D CONVERTER The ST62T20M6/HWD is a microcontroller manufactured by SGS-THOMSON (now STMicroelectronics). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** SGS-THOMSON (STMicroelectronics)  
- **Core:** 8-bit ST6 core  
- **Operating Voltage:** 4.5V to 5.5V  
- **Clock Frequency:** Up to 8 MHz  
- **Program Memory (ROM):** 2 KB  
- **RAM:** 64 bytes  
- **EEPROM:** 128 bytes  
- **I/O Ports:** 20 I/O pins  
- **Timers:** 8-bit timer with 7-bit prescaler  
- **ADC:** None  
- **Communication Interfaces:** None (basic I/O only)  
- **Packaging:** 20-pin DIP (Dual In-line Package)  

### **Descriptions:**  
The ST62T20M6/HWD is an 8-bit microcontroller from the ST6 family, designed for cost-sensitive embedded applications. It features a simple architecture with on-chip ROM, RAM, and EEPROM, making it suitable for basic control tasks.  

### **Features:**  
- **8-bit ST6 Core:** Efficient for simple control applications.  
- **On-Chip Memory:** Includes 2 KB ROM, 64 bytes RAM, and 128 bytes EEPROM.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V.  
- **20 I/O Pins:** Configurable for digital input/output.  
- **Built-in Timer:** 8-bit timer with a 7-bit prescaler.  
- **Low-Power Modes:** Supports power-saving modes.  
- **Industrial Temperature Range:** Suitable for various environments.  

This microcontroller is typically used in appliances, automotive systems, and industrial controls where basic processing is required.  

(Note: SGS-THOMSON rebranded as STMicroelectronics in 1987, but the ST6 family remained in production for legacy applications.)

Application Scenarios & Design Considerations

8-BIT OTP/EPROM MCUs WITH A/D CONVERTER

Alternative Part Number

  • PIC16F628A-I/SO --: 8-bit flash microcontroller in SOIC-20 with comparable I/O and peripherals; widely available and easy to port from ST62 architecture.
  • AT89C4051-24SU --: 8051-core 8-bit MCU in SOIC-20 with similar pin count and low-cost, suitable for simple control applications replacing ST62T20.
  • PIC16F1824-I/SL --: Modern low-power 8-bit MCU in SOIC-14/20 family with enhanced peripherals; good functional fit when board space allows re-layout.
  • AT89C2051-24SU --: 8051-based 8-bit MCU in SOIC with similar pin count and peripherals, a common substitute for legacy ST62 designs.
  • MC68HC908QT4CDW --: Low-cost 8-bit microcontroller in SOIC with comparable features, usable as an alternative for obsolete SGS-Thomson parts.
