Description and Introduction

TMS27PC512 65536 BY 8-BIT PROGRAMMABLE READ-ONLY MEMORIES The **TMS27PC512** is a 512K-bit (64K x 8) UV-erasable programmable read-only memory (EPROM) manufactured by Texas Instruments.  

### **Key Specifications:**  
- **Organization:** 64K x 8 (65,536 words x 8 bits)  
- **Access Time:** 150 ns (typical)  
- **Supply Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active: 100 mA (max)  
  - Standby: 30 mA (max)  
- **Programming Voltage (VPP):** 12.5V  
- **Operating Temperature Range:** 0°C to 70°C (commercial)  
- **Package Options:** 28-pin DIP (Dual In-line Package)  

### **Features:**  
- **UV-Erasable:** Can be erased by exposure to ultraviolet light.  
- **Single 5V Power Supply:** No additional power supply needed for read operations.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Programmable:** Supports standard EPROM programming methods.  
- **High Reliability:** Designed for industrial and commercial applications.  

This EPROM is commonly used in embedded systems, legacy computing, and microcontroller-based applications requiring non-volatile memory storage.
