PYX28C64 is a 5 Volt 8Kx8 EEPROM using floating gate CMOS Technology. The device supports 64-byte page write operation and features DATA and Toggle Bit Polling, as well as a system software scheme used to indicate early completion of a Write Cycle. The device also includes user-optional software data protection. Endurance is 10,000 or 100,000 Cycles and Data Retention is 100 Years.
The PYX28C64 is a 5 V 8K×8 EEPROM using floating‑gate CMOS technology. It supports 64‑byte page‑write operation, offers software data protection, and provides several access‑time options (200‑350 ns). Endurance is specified at 10 000 or 100 000 cycles with a data‑retention period of 100 years.
The device is supplied in 32‑pin ceramic LCC and 28‑pin ceramic DIP packages. Electrical characteristics include a 60 mA active current, 200 pA standby current, and a supply voltage range of –0.3 V to +6.25 V. Detailed timing diagrams for read, byte‑write, page‑write, and chip‑clear cycles are provided, along with maximum ratings and package dimensions.
