Description and Introduction

4 194 304-Bit Programmable Read-Only Memory 32-CDIP -40 to 85 The TMS27C040-15JE is a 4-megabit (512K x 8) UV-erasable programmable read-only memory (EPROM) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Organization:** 512K x 8  
- **Speed:** 150 ns (15 in part number indicates access time in 10s of ns, so 15 x 10 = 150 ns)  
- **Supply Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active: 100 mA (max)  
  - Standby: 30 mA (max)  
- **Operating Temperature Range:** Commercial (0°C to 70°C)  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Technology:** UV-erasable, electrically programmable  
- **Data Retention:** 10 years minimum  

### **Descriptions and Features:**  
- **High-Speed Access Time:** 150 ns  
- **Single 5V Power Supply Operation**  
- **Low Power Consumption** in both active and standby modes  
- **UV-Erasable:** Can be erased by exposure to ultraviolet light for reprogramming  
- **Electrically Programmable:** Uses standard EPROM programming equipment  
- **CMOS Technology:** Provides high noise immunity and low power consumption  
- **JEDEC Approved:** Complies with industry-standard pinout  
- **Three-State Outputs:** Allows for bus-oriented applications  

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