5 Volt, Byte Alterable EEPROM

Features

The X28HC64 is an 8K x 8 EEPROM, fabricated with Intersil’s

proprietary, high performance, floating gate CMOS

technology. Like all Intersil programmable nonvolatile

memories, the X28HC64 is a 5V only device. It features the

JEDEC approved pinout for byte-wide memories, compatible

with industry standard RAMs.

• 70ns access time

• Simple byte and page write

- Single 5V supply

- No external high voltages or V_PPcontrol circuits

- Self-timed

- No erase before write

The X28HC64 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

X28HC64 also features DATA Polling and Toggle Bit Polling,

two methods providing early end of write detection. In addition,

the X28HC64 includes a user-optional software data protection

mode that further enhances Intersil’s hardware write protect

capability.

- No complex programming algorithms

- No overerase problem

• Low power CMOS

- 40mA active current max.

• 200µA standby current max.

• Fast write cycle times

- 64-byte page write operation

- Byte or page write cycle: 2ms typical

- Complete memory rewrite: 0.25 sec. typical

- Effective byte write cycle time: 32µs typical

Intersil EEPROMs are designed and tested for applications

requiring extended endurance. Inherent data retention is

greater than 100 years.

• Software data protection

• End of write detection

- DATA polling

- Toggle bit

• High reliability

- Endurance: 100000 cycles

- Data retention: 100 years

• JEDEC approved byte-wide pin out

• Pb-free available (RoHS compliant)
