DATASHEET

256k, 32k x 8-Bit, 5V, Byte Alterable EEPROM

X28HC256

Features

The X28HC256 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.

• Access time: 90ns

• Simple byte and page write

- Single 5V supply

- No external high voltages or V_P-Pcontrol circuits

- Self timed

The X28HC256 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

X28HC256 also features DATA polling and Toggle bit polling,

two methods of providing early end of write detection. The

X28HC256 also supports the JEDEC standard software data

protection feature for protecting against inadvertent writes

during power-up and power-down.

- No erase before write

- No complex programming algorithms

- No overerase problem

• Low power CMOS

- Active: 60mA

- Standby: 500µA

Endurance for the X28HC256 is specified as a minimum

100,000 write cycles per byte and an inherent data retention

of 100 years.

• Software data protection

- Protects data against system level inadvertent writes

• High speed page write capability

• Highly reliable Direct Write^™cell

- Endurance: 100,000 cycles

- Data retention: 100 years

• Early end of write detection

- DATA polling

- Toggle bit polling

• RoHS compliant
