M27C322-100F1, 32Mbit (2Mb x16) UV EPROM and OTP EPROM, DIP-42

The M27C322-100F1 is a 32Mbit (2Mb x 16-bit) UltraViolet Erasable Programmable Read-Only Memory (UV EPROM) and One-Time Programmable (OTP) EPROM designed for high-speed embedded systems, firmware storage, and industrial applications. It is a drop-in replacement for standard 32Mbit Mask ROMs and is fully compatible with microprocessor-based systems.

With a fast 100ns access time, the M27C322 ensures reliable performance in time-critical operations. The low power consumption allows efficient power usage, making it suitable for automotive, industrial control, and legacy computing applications.

The FDIP42W package includes a transparent window that allows UV erasure, enabling reprogramming for development and prototyping. The PDIP42 package is intended for permanent one-time programming (OTP), ensuring secure firmware storage.

The device supports a 2-line output control function, ensuring low power dissipation and preventing output contention when used in large memory arrays. Its electronic signature allows easy identification by programming equipment, simplifying system integration.

Ideal for BIOS storage, gaming systems, automotive applications, and embedded firmware storage, the M27C322 is a versatile and reliable non-volatile memory solution.
