Microchip Technology AT28HC256E-90LL is a 262,144-bit (32K x 8) CMOS parallel EEPROM. This device offers a 90ns maximum access time and features automatic write capabilities for simplified data storage operations. Designed for robust performance, it operates asynchronously and supports a supply voltage range of 4.5V to 5.5V. The AT28HC256E-90LL is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) with a rectangular shape and metal-sealed cofired construction. Its 3-state output characteristics are suitable for various bus configurations. Applications include industrial control, telecommunications, and data logging systems where reliable non-volatile memory is critical. This component utilizes CMOS technology for low power consumption.
