Description and Introduction

2 097 152-Bit Programmable Read-Only Memory 32-CDIP The TMS27C020-10JL is a 2Mbit (256K x 8) UV-erasable and electrically programmable read-only memory (EPROM) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Memory Size:** 2 Mbit (256K x 8)  
- **Access Time:** 100 ns  
- **Operating Voltage:** 5V ± 10%  
- **Power Dissipation:**  
  - Active: 525 mW (max)  
  - Standby: 110 mW (max)  
- **Programming Voltage (VPP):** 12.5V  
- **Data Retention:** 10 years minimum  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  

### **Features:**  
- **High-Speed Access:** 100 ns read access time  
- **Low Power Consumption:** CMOS technology for reduced power usage  
- **UV-Erasable:** Can be erased with UV light for reprogramming  
- **Single 5V Supply:** For read operations  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels  
- **Programmable:** Electrically programmable for flexibility  
- **Three-State Outputs:** Supports bus-oriented systems  

This EPROM is designed for applications requiring non-volatile memory storage with reprogramming capability.

Application Scenarios & Design Considerations

2 097 152-Bit Programmable Read-Only Memory 32-CDIP

Alternative Part Number

  • M27C2001-10F1 --: 2 Mbit UV EPROM with the same 256K x 8 organization and 100 ns access time, pin-compatible DIP-32 package, widely available as a direct replacement.
  • AM27C020-100DC --: 2 Mbit CMOS EPROM in 32-pin DIP with 100 ns speed, functionally equivalent to the TMS27C020 and a common second-source option.
  • M27C2001-10C1 --: Same 2 Mbit EPROM density and 100 ns timing in a PLCC-32 package, suitable when the JL package footprint needs a plastic leaded chip carrier alternative.
