X28HC256FMB-12 Description

Short technical summary and product information.

The Intersil X28HC256FMB-12 is a high-performance CMOS 32k x 8 EEPROM, utilizing Intersil's proprietary textured poly floating gate technology for reliable 5V nonvolatile memory.

 

This EEPROM supports a 128-byte page write operation, achieving a write cycle of 24µs/byte and allowing the entire memory to be rewritten in under 0.8 seconds. It includes DATA polling and Toggle bit polling for early end-of-write detection and supports the JEDEC standard software data protection feature.

 

Key electrical specifications include a 90ns access time, 5V single supply operation, and low standby current of 0.5 mA. The device is rated for an operating temperature range of -40°C to 85°C.

 

Endurance is specified at a minimum of 100,000 write cycles per byte, with an inherent data retention of 100 years. The package information indicates that the package is retired, and users should contact the manufacturer for further details.
