Description and Introduction

8-bit Microcontroller 8 Kbytes ROM/OTP, ROMless The **TS87C52X2-MCA** is an 8-bit microcontroller from the **MCS-51** family, manufactured by **Atmel** (now part of Microchip Technology). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Core:** 80C52-compatible  
- **Architecture:** 8-bit  
- **Clock Speed:** Up to **33 MHz**  
- **Program Memory (ROM):** **8 KB** (OTP - One-Time Programmable)  
- **RAM:** **256 bytes**  
- **Timers:** Three 16-bit timers/counters (Timer 0, Timer 1, and Timer 2)  
- **I/O Ports:** Four 8-bit bidirectional ports (P0, P1, P2, P3)  
- **Serial Communication:** Full-duplex UART  
- **Interrupts:** Six interrupt sources with two priority levels  
- **Power Supply:** **4.5V to 5.5V**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **PLCC-44** (Plastic Leaded Chip Carrier)  

### **Descriptions:**  
- The **TS87C52X2-MCA** is a high-performance CMOS version of the **80C52** microcontroller.  
- It features **8 KB of OTP ROM**, making it suitable for applications requiring one-time programming.  
- It is fully compatible with the **MCS-51** instruction set.  
- Includes power-saving **Idle** and **Power-Down** modes.  

### **Features:**  
- **High-Speed Operation:** Up to **33 MHz** clock frequency.  
- **Enhanced MCS-51 Core:** Improved performance over standard 8051.  
- **On-Chip OTP ROM:** 8 KB of one-time programmable memory.  
- **256 Bytes of On-Chip RAM:** For data storage.  
- **Three 16-Bit Timers:** For timing and event counting.  
- **Full-Duplex UART:** Supports serial communication.  
- **Six Interrupt Sources:** Configurable with two priority levels.  
- **Low-Power Modes:** Idle and Power-Down modes for energy efficiency.  
- **Wide Operating Voltage Range:** **4.5V to 5.5V**.  
- **Industrial Temperature Range:** **-40°C to +85°C**.  

This microcontroller is commonly used in industrial control systems, embedded applications, and other scenarios requiring an **MCS-51**-compatible device with OTP memory.

Application Scenarios & Design Considerations
