Description and Introduction

4 Megabit (512 K x 8-Bit) CMOS EPROM The AM27C040-150JC is a 4 Megabit (512K x 8) UV erasable and electrically programmable read-only memory (EPROM) manufactured by Advanced Micro Devices (AMD). Key specifications include:

- **Organization**: 512K x 8 bits
- **Access Time**: 150 ns
- **Operating Voltage**: 5V ± 10%
- **Programming Voltage**: 12.75V ± 0.25V
- **Package**: 32-pin PLCC (Plastic Leaded Chip Carrier)
- **Operating Temperature Range**: 0°C to +70°C
- **UV Erase Time**: 15 to 20 minutes using a UV lamp with a wavelength of 2537 Å
- **Data Retention**: 10 years minimum
- **Power Dissipation**: Active current of 30 mA (typical), standby current of 100 µA (typical)

The device is designed for high-performance, high-reliability applications and is compatible with standard EPROM programmers.

Application Scenarios & Design Considerations

4 Megabit (512 K x 8-Bit) CMOS EPROM

Alternative Part Number

  • M27C4001-15F1 --: 4 Mbit UV EPROM in a 32-pin package with 150 ns access time, functionally equivalent to the AM27C040 and widely available.
  • M27C4001-12F1 --: Same 4 Mbit EPROM family with faster 120 ns access time, pin-compatible and a common drop-in replacement.
  • TMS27C040-15JL --: 4 Mbit CMOS EPROM with 150 ns access time in a 32-pin package, a direct functional alternative from a different series.
