The W27C020-70 is a 2Mbit Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for high-speed and low-power applications. This memory device is organized as 256K × 8 bits, operating on a single 5V power supply for both reading and writing operations.
Unlike conventional UVEPROMs, which require ultraviolet light for erasure, the W27C020-70 supports electrical erasure, significantly reducing erase times to 100ms, making it highly efficient for industrial, embedded, and computing applications.
The device features three-state outputs, making it compatible with TTL/CMOS logic. It supports chip erase functionality, allowing for bulk erasure of all stored data. The programming operation allows byte-wise data modification, ensuring precise data management.
With an endurance of 100,000 program/erase cycles and a data retention period of up to 20 years, the W27C020-70 is ideal for applications requiring firmware storage, BIOS updates, industrial control systems, and embedded system development.
