Description and Introduction

High Performance 8-bit Microcontroller The **TS87C51RC2-MCB** is a microcontroller manufactured by **Atmel (now part of Microchip Technology)**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Architecture:** 8-bit  
- **Core:** 8051  
- **Clock Speed:** Up to 33 MHz  
- **Program Memory (Flash/ROM):** 32 KB (OTP ROM)  
- **RAM:** 512 bytes  
- **EEPROM:** None  
- **I/O Pins:** 32  
- **Timers:** 3 (Timer 0, Timer 1, and Timer 2)  
- **UART:** 1 (Full-duplex)  
- **Interrupt Sources:** 6  
- **Operating Voltage:** 4.5V to 5.5V  
- **Power Consumption:** Low-power idle and power-down modes  
- **Package:** PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The **TS87C51RC2-MCB** is a high-performance CMOS version of the 80C51 microcontroller.  
- It features **One-Time Programmable (OTP) ROM**, making it suitable for applications requiring fixed firmware.  
- It retains full compatibility with the 8051 instruction set.  
- Designed for embedded control applications, including industrial, automotive, and consumer electronics.  

### **Features:**
- **High-Speed 8051 Core:** Executes most instructions in 1 or 2 clock cycles.  
- **32 KB OTP ROM:** Non-volatile memory for program storage.  
- **512 Bytes On-Chip RAM:** For data storage and stack operations.  
- **Three 16-bit Timers:** Supports timing, event counting, and PWM generation.  
- **Full-Duplex UART:** For serial communication.  
- **Boolean Processor:** Bit-addressable operations for efficient control applications.  
- **Low EMI (Electromagnetic Interference):** Suitable for noise-sensitive environments.  
- **Power-Saving Modes:** Idle and power-down modes for reduced power consumption.  
- **Wide Operating Voltage Range:** Supports standard 5V operation.  

This microcontroller is commonly used in applications requiring **high reliability and deterministic performance**, such as industrial automation, motor control, and embedded systems.  

*(Note: The TS87C51RC2-MCB is an older OTP-based variant; newer flash-based alternatives may be available from Microchip.)*

Application Scenarios & Design Considerations

High Performance 8-bit Microcontroller

Alternative Part Number

  • AT89C51RC2-IM --: Pin-compatible 8051-family microcontroller with similar ROM/RAM and peripherals; Microchip now owns the former Temic/Atmel 8051 line, making this a direct functional replacement.
  • P89C51RC2BN --: 8051-compatible MCU with comparable code memory and I/O, widely available and commonly used as a drop-in substitute for Temic 87C51RC2 devices.
  • W78E516B-40PL --: Alternative 8051-core microcontroller with similar memory and peripheral set, suitable for legacy Temic 87C51RC2 designs when exact part is unavailable.
