Description and Introduction

READ-ONLY MEMORIES The TMS27C020-20JE is a 2 Megabit (256K x 8) UV-erasable and electrically programmable read-only memory (EPROM) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Organization:** 256K x 8  
- **Access Time:** 200 ns (20 in the part number denotes speed grade)  
- **Supply Voltage (VCC):** 5V ± 10%  
- **Power Consumption:**  
  - Active: 100 mA (max)  
  - Standby: 30 mA (max)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 32-pin Ceramic DIP (PDIP)  

### **Descriptions and Features:**  
- **UV-Erasable:** Can be erased by exposure to ultraviolet light for reprogramming.  
- **Electrically Programmable:** Uses standard EPROM programming voltages.  
- **Single 5V Power Supply:** Simplifies system design.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with standard logic levels.  
- **Three-State Outputs:** Allows bus sharing in microprocessor-based systems.  
- **High Reliability:** Features include noise immunity and robust data retention.  

This EPROM is commonly used in embedded systems, firmware storage, and legacy computing applications.  

(Note: Always refer to the official datasheet for detailed technical specifications.)

Application Scenarios & Design Considerations

READ-ONLY MEMORIES

Alternative Part Number

  • M27C2001-20F1 --: 2 Mbit UV EPROM in a 32-pin ceramic DIP, same 200 ns access time and pinout as the original, widely available from ST.
  • AM27C020-200DC --: 2 Mbit CMOS EPROM with 200 ns access time in a 32-pin ceramic DIP, functionally equivalent and a common second source.
  • M27C2001-20C1 --: Same 2 Mbit EPROM family in a 32-pin ceramic package with 200 ns speed, suitable as a drop-in replacement when the F1 variant is unavailable.
