Intersil X28HC256JIZ-90

32K x 890 ns-40°C ~ 85°C（TA）

Overview

The X28HC256JIZ-90 is a second generation high performance CMOS 32k x 8 EEPROM. It is fabricated with Intersil’s proprietary, textured poly floating gate technology, providing a highly reliable 5V only nonvolatile memory. The X28HC256JIZ-90 supports a 128-byte page write operation, effectively providing a 24μs/byte write cycle, and enabling the entire memory to be typically rewritten in less than 0.8s. The X28HC256JIZ-90 also featuresDATA polling and Toggle bit polling, two methods of providing early end of write detection. The X28HC256JIZ-90 also supports the JEDEC standard software data protection feature for protecting against inadvertent writes during power-up and power-down. Endurance for the X28HC256JIZ-90 is specified as a minimum 100,000 write cycles per byte and an inherent data retention of 100 years
