W27C01-70, 1Mbit (128K x 8) Electrically Erasable EPROM, DIP-32

The W27C01-70 is a 1Mbit (128K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for high-speed, low-power applications that require non-volatile memory with electrical reprogramming capability. Unlike traditional UV EPROMs, this memory can be erased and reprogrammed electrically, eliminating the need for UV exposure.

With a 70ns access time, this EEPROM enables rapid data access, making it ideal for BIOS storage, industrial control systems, and embedded firmware applications. The W27C01-70 operates with a single 5V power supply, removing the complexity of high-voltage programming.

The device supports sector-based programming and erasure, ensuring efficient memory management. Additionally, the low standby current (5µA typical) enhances power efficiency in battery-operated systems.

The DIP-32 package follows JEDEC-standard pin configurations, ensuring compatibility with a wide range of legacy and modern computing architectures. It is widely used in automotive electronics, industrial automation, and networking equipment where reliable and secure firmware storage is essential.
