Description and Introduction

READ-ONLY MEMORIES The **TMS27C020-20** is a 2 Megabit (256K x 8) UV-erasable and electrically programmable read-only memory (EPROM) manufactured by **Intel**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 256K x 8 (2 Megabit)  
- **Access Time:** 200 ns (indicated by the "-20" suffix)  
- **Supply Voltage:** 5V ±10%  
- **Operating Current:** 30 mA (typical)  
- **Standby Current:** 100 µA (typical)  
- **Programming Voltage (VPP):** 12.5V  
- **Technology:** CMOS  
- **Package:** 32-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**
- The **TMS27C020-20** is a high-performance EPROM that can be erased by exposure to ultraviolet (UV) light and reprogrammed electrically.  
- It is designed for applications requiring non-volatile memory storage, such as firmware, BIOS, and embedded systems.  
- The "-20" suffix denotes an access time of 200 ns, making it suitable for systems with moderate speed requirements.  

### **Features:**
- **UV-Erasable:** Can be erased by UV light for reprogramming.  
- **Single 5V Power Supply:** Operates on standard 5V power during read operations.  
- **Low Power Consumption:** Features low standby current for power-efficient designs.  
- **Compatibility:** Pin-compatible with other 27C020 EPROMs.  
- **High Reliability:** Designed for industrial and commercial applications with robust performance.  

This information is based on Intel's specifications for the **TMS27C020-20** EPROM.

Application Scenarios & Design Considerations

READ-ONLY MEMORIES

Alternative Part Number

  • M27C2001-20F1 --: 2 Mbit UV EPROM with the same 256K x 8 organization and 200 ns access time, pin-compatible DIP-32 package, widely available from a major vendor.
  • AM27C020-200DC --: Direct 2 Mbit CMOS EPROM equivalent with 200 ns speed grade and matching pinout, a common second-source replacement for the TMS27C020.
  • M27C2001-20C1 --: Same 2 Mbit EPROM density and 200 ns timing in a PLCC-32 package, suitable when board layout allows the alternate footprint.
