Description and Introduction

4/194/304-Bit 512K x 8 High Performance CMOS EPROM The FM27C040Q-90 is a 4 Megabit (512K x 8) UV erasable CMOS EPROM manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Here are the key specifications:

- **Organization**: 512K x 8  
- **Speed**: 90 ns access time  
- **Technology**: CMOS  
- **Supply Voltage**: 5V ± 10%  
- **Operating Current**: 30 mA (typical)  
- **Standby Current**: 100 µA (typical)  
- **Programming Voltage (VPP)**: 12.5V  
- **Package**: 32-lead PLCC, 32-lead PDIP, or 32-lead TSOP  
- **Operating Temperature Range**: 0°C to +70°C
