Description and Introduction

8-BIT PROGRAMMABLE READ-ONLY MEMORIES The **TMS27C010A-20** is a 1Mbit (128K x 8) UV-erasable programmable read-only memory (EPROM) manufactured by **Texas Instruments (TI)**.  

### **Key Specifications:**  
- **Organization:** 128K x 8  
- **Speed:** 200 ns (access time)  
- **Supply Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 32-pin DIP (Dual In-line Package)  
- **Technology:** CMOS  

### **Features:**  
- **UV-Erasable:** Can be erased by exposure to ultraviolet light.  
- **Single 5V Power Supply:** No additional voltages required for read operations.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Low Power Consumption:**  
  - Active current: 30 mA (typical)  
  - Standby current: 100 µA (typical)  
- **Programmable:** Supports standard EPROM programming methods.  
- **Three-State Outputs:** Allows for bus sharing in microprocessor systems.  

### **Applications:**  
- Microcontroller-based systems  
- Firmware storage  
- Legacy computing and embedded systems  

This EPROM is designed for applications requiring non-volatile memory with reprogrammability via UV erasure.
