Description and Introduction

8-bit Microcontroller 8 Kbytes ROM/OTP, ROMless The **TS87C52X2-LCB** is a microcontroller manufactured by **ATMEL**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Core:** 80C52 (8-bit microcontroller)  
- **Architecture:** MCS-51 compatible  
- **Clock Speed:** Up to **33 MHz**  
- **Program Memory (ROM):** **8 KB** (OTP - One-Time Programmable)  
- **RAM:** **256 bytes**  
- **EEPROM:** None  
- **Timers:** Three 16-bit timers/counters (Timer 0, Timer 1, and Timer 2)  
- **I/O Ports:** Four 8-bit ports (Port 0, Port 1, Port 2, Port 3)  
- **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 (Plastic Leaded Chip Carrier)**  

### **Descriptions:**
- The **TS87C52X2-LCB** is a high-performance CMOS version of the 80C51 microcontroller.  
- It is **OTP (One-Time Programmable)**, meaning the program memory can be written once and cannot be erased.  
- It is optimized for embedded control applications requiring high-speed processing.  

### **Features:**
- **High-Speed Operation:** Up to **33 MHz** clock frequency.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Enhanced MCS-51 Architecture:** Backward-compatible with the 80C51 instruction set.  
- **On-Chip Oscillator:** Supports crystal or external clock input.  
- **Power-Saving Modes:** Includes **Idle Mode** and **Power-Down Mode**.  
- **Watchdog Timer:** Helps prevent software lock-ups.  
- **Boolean Processor:** Supports bit-level operations for efficient control applications.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

8-bit Microcontroller 8 Kbytes ROM/OTP, ROMless

Alternative Part Number

  • P87C52X2FN --: Same 8051-compatible 87C52 architecture with 8-bit MCU, 256 bytes RAM and 8K OTP ROM; NXP (formerly Philips) is the original 80C51 family source and offers comparable speed grades and pinout.
  • AT89C52-24PU --: Atmel/Microchip 8051-compatible MCU with 8K flash, 256 bytes RAM and 32 I/O lines; direct functional replacement in the same 40-pin DIP package with similar timing.
  • W78E52B-24 --: 8051-compatible 8-bit MCU with 8K flash and 256 bytes RAM, pin-compatible with the 87C52 family and widely available as a cost-effective drop-in alternative.
  • AT89C52-24PC --: Pin-compatible 8051-family microcontroller with 8KB flash, same 40-pin DIP footprint and instruction set, widely available and a direct functional replacement for the 87C52 EPROM device.
  • P89C52X2BN --: 8051-compatible microcontroller with 8KB flash and the same X2 clock-doubling architecture as the TS87C52X2, offering equivalent performance in a matching package.
  • AT89C52-24JC --: Pin-compatible 8051 microcontroller with 8KB flash program memory and 256 bytes RAM in PLCC44, suitable direct replacement with similar speed grade.
  • W78E52B-24PL --: 8051-compatible microcontroller with 8KB flash and PLCC44 footprint, offering comparable performance and pinout for drop-in substitution.
