Description and Introduction

16-BIT PROGRAMMABLE READ-ONLY MEMORIES The TMS27C240 is a 4M-bit (512K x 8) UV-erasable and electrically programmable read-only memory (EPROM) manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Memory Size:** 4M-bit (512K x 8)  
- **Technology:** UV-erasable EPROM  
- **Access Time:** Varies (e.g., 120ns, 150ns, etc., depending on the speed grade)  
- **Operating Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active current: ~50mA (typical)  
  - Standby current: ~100µA (typical)  
- **Package Options:** 32-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to 70°C) or Industrial (-40°C to 85°C)  

### **Features:**  
- **High-Speed Performance:** Fast access time suitable for high-performance applications.  
- **UV-Erasable:** Can be erased by exposure to ultraviolet light for reprogramming.  
- **Single 5V Power Supply:** Simplifies system design.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Programmable:** Supports standard EPROM programming methods.  
- **Reliable:** High endurance and data retention characteristics.  

### **Applications:**  
- Embedded systems  
- Firmware storage  
- Microcontroller-based applications  
- Legacy computing and industrial control systems  

For exact speed grades, timing parameters, and additional details, refer to the official TI datasheet for the TMS27C240.
