X28C010
5 Volt, Byte Alterable E2PROM
DESCRIPTION
128K x 8 Bit
FEATURES
2
The Xicor X28C010 is a 128K x 8 E PROM, fabricated
with Xicor's proprietary, high performance, floating gate
CMOS technology. Like all Xicor programmable non-
volatile memories the X28C010 is a 5V only device. The
X28C010 features the JEDEC approved pinout for byte-
wide memories, compatible with industry standard
EPROMs.
• Access Time: 120ns
• Simple Byte and Page Write
—Single 5V Supply
—No External High Voltages or V Control Circuits
—Self-Timed
PP
—No Erase Before Write
—No Complex Programming Algorithms
—No Overerase Problem
• Low Power CMOS:
TheX28C010supportsa256-bytepagewriteoperation,
effectively providing a 19µs/byte write cycle and en-
abling the entire memory to be typically written in less
than 2.5 seconds. The X28C010 also features DATA
Polling and Toggle Bit Polling, system software support
schemes used to indicate the early completion of a write
cycle. In addition, the X28C010 supports Software Data
Protection option.
—Active: 50mA
—Standby: 500µA
• Software Data Protection
—Protects Data Against System Level
Inadvertant Writes
• High Speed Page Write Capability
• Highly Reliable Direct Write™ Cell
—Endurance: 100,000 Write Cycles
—Data Retention: 100 Years
• Early End of Write Detection
—DATA Polling
2
Xicor E PROMs are designed and tested for applica-
tions requiring extended endurance. Data retention is
specified to be greater than 100 years.
