Description and Introduction

High Performance 8-bit Microcontroller The TS87C51RB2-MCB is a microcontroller manufactured by TEMIC (now part of Atmel). Below are the factual specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Architecture:** 8-bit  
- **Core:** 80C51  
- **Clock Speed:** Up to 16 MHz  
- **Program Memory (ROM):** 16 KB (OTP - One-Time Programmable)  
- **RAM:** 256 bytes  
- **Data Memory (EEPROM):** 2 KB  
- **I/O Ports:** 32 (Four 8-bit ports)  
- **Timers/Counters:** 3 (Two 16-bit timers, one with additional event counter)  
- **Serial Communication:** Full-duplex UART  
- **Interrupts:** 6 sources with 2 priority levels  
- **Power Supply:** 4.5V to 5.5V  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** 40-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The TS87C51RB2-MCB is a high-performance CMOS version of the 80C51 microcontroller.  
- It features OTP (One-Time Programmable) ROM, making it suitable for production environments where firmware is fixed.  
- Includes an integrated 2 KB EEPROM for non-volatile data storage.  
- Designed for embedded control applications requiring reliability and low power consumption.  

### **Features:**  
- **Enhanced 80C51 Core:** Backward-compatible with standard 80C51 instruction set.  
- **Low Power Modes:** Idle and Power-down modes for reduced power consumption.  
- **Watchdog Timer:** Improves system reliability by resetting the microcontroller in case of software failure.  
- **Programmable Clock Output:** Allows external peripheral synchronization.  
- **Boolean Processor:** Supports bit-level operations for efficient control applications.  
- **High Noise Immunity:** Robust design for industrial environments.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official datasheet.

Application Scenarios & Design Considerations

High Performance 8-bit Microcontroller

Alternative Part Number

  • AT89C51RB2-IM --: Same 8051 core with 16KB flash in a 44-pin PLCC package, pin-compatible with the TS87C51RB2-MCB and widely available.
  • P89C51RB2FBD --: 8051-compatible microcontroller with 16KB flash in PLCC44, functionally equivalent and a common drop-in replacement.
  • W78E516B40PL --: 8051-compatible MCU with 64KB flash in PLCC44, offers more memory and can substitute with minor firmware adjustment.
  • P89C51RB2HBA --: 8051-compatible MCU with matching 16KB flash and RB2 configuration, offering similar peripherals and operating voltage range for drop-in substitution.
  • W78E516B-40PL --: Alternative 8051-core microcontroller with comparable flash memory and I/O features, suitable when the original TEMIC part is unavailable.
  • P87C51RB2FN --: Same 8051 core with 16 KB OTP program memory in a PLCC44 package, functionally compatible with the TS87C51RB2-MCB.
