- **Clock Speed:** Up to **40 MHz**  
- **Program Memory (Flash):** **64 KB** (expandable via external memory)  
- **RAM:** **1 KB** (internal)  
- **Data Memory (XRAM):** **1 KB** (expandable up to **64 KB** externally)  
- **EEPROM:** **2 KB** (for data storage)  
- **Operating Voltage:** **4.5V to 5.5V**  
- **I/O Pins:** **32** (4 ports of 8 bits each)  
- **Timers:** **3** (16-bit timers/counters)  
- **UART:** **Full-duplex serial port**  
- **Interrupt Sources:** **7** (with 4 priority levels)  
- **Watchdog Timer:** Yes  
- **Power Saving Modes:** Idle and Power-down modes  
- **Package:** **PLCC44** (Plastic Leaded Chip Carrier, 44 pins)  

### **Descriptions:**
- The **TS80C51RD2-MCB** is a high-performance CMOS version of the **80C51** microcontroller.  
- It is **fully compatible** with the standard 8051 instruction set.  
- Features **in-system programmable (ISP) Flash memory**, allowing firmware updates without removing the chip.  
- Supports **external memory expansion** for both code and data.  
- Includes **hardware watchdog** for improved system reliability.  

### **Features:**
- **High-Speed Operation:** Up to **40 MHz** clock frequency.  
- **Large Memory Capacity:** 64 KB Flash, 1 KB RAM, and 2 KB EEPROM.  
- **Enhanced 8051 Core:** 6-clock or 12-clock operation selectable.  
- **Low Power Consumption:** Supports **Idle** and **Power-down** modes.  
- **Multiple Communication Interfaces:** UART, SPI (via software), and I2C (via software).  
- **Robust Peripheral Set:** Includes timers, interrupts, and watchdog timer.  
- **Industrial Temperature Range:** **-40°C to +85°C**.  

This microcontroller is commonly used in **industrial control systems, embedded applications, and consumer electronics** due to its high performance and reliability.  

(Note: The manufacturer may have discontinued or updated this product, so verify with official Microchip/Atmel resources for the latest details.)
