Intersil X28HC64 EEPROM Datasheet
Datasheet 17 pages · 180 KB · EN
The X28HC64 EEPROM, fabricated with Intersil’s floating‑gate CMOS technology, offers 8 K × 8 bits of non‑volatile memory in a 5 V‑only device. It features a JEDEC‑approved byte‑wide pinout, 64‑byte page write capability, and both DATA and Toggle‑Bit polling for early end‑of‑write detection.
The datasheet provides detailed ordering information, pin configurations, timing diagrams for read, write, and page‑write operations, as well as hardware and software data‑protection features that safeguard against inadvertent writes.
