Intersil X28HC64D-90

8K x 890 ns0°C ~ 70°C（TA）

Overview

The X28HC64D-90 is an 8k x 8 EEPROM, fabricated with Intersil’s proprietary, high performance, floating gate CMOS technology. Like all Intersil programmable nonvolatile memories, the X28HC64D-90 is a 5V only device. It features the JEDEC approved pinout for byte-wide memories, compatible with industry standard RAMs.The X28HC64D-90 supports a 64-byte page write operation, effectively providing a 32μs/byte write cycle, and enabling the entire memory to be typically written in 0.25 seconds. The X28HC64D-90 also features DATA Polling and Toggle Bit Polling, two methods providing early end of write detection. In addition, the X28HC64D-90 includes a user-optional software data protection mode that further enhances Intersil’s hardware write protect capability.Intersil EEPROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
