Description and Introduction 4 Megabit (512 K x 8-Bit) CMOS EPROM The AM27C040-90DE is a 4 Megabit (512K x 8) UV erasable and electrically programmable read-only memory (EPROM) manufactured by AMD. Key specifications include: - Organization: 512K x 8 bits - Access Time: 90 ns - Operating Voltage: 5V ± 10% - Programming Voltage: 12.75V ± 0.25V - Package: 32-pin DIP (Dual In-line Package) - Technology: CMOS - Operating Temperature Range: 0°C to +70°C - Data Retention: 10 years minimum - Programming Method: Fast programming algorithm - UV Erase Time: 20 minutes (minimum) under UV light at 2537 Å This EPROM is designed for applications requiring non-volatile memory storage and is suitable for use in a wide range of electronic systems.
Application Scenarios & Design Considerations 4 Megabit (512 K x 8-Bit) CMOS EPROM
Alternative Part Number M27C4001-90F1 --: 4 Mbit UV EPROM with similar 90 ns access time and DIP-32 pinout, a common drop-in replacement for the AM27C040. M27C4001-10F1 --: Same 4 Mbit EPROM family and pinout; 100 ns access time is slightly slower but usually acceptable in non-timing-critical sockets. 27C040-90 --: Direct 4 Mbit CMOS EPROM equivalent with 90 ns speed and compatible DIP-32 pinout from a major second-source vendor.
