XM28C020

2 Megabit Module

XM28C020

5 Volt, Byte Alterable E²PROM

DESCRIPTION

256K x 8 Bit

TYPICAL FEATURES

The XM28C020 is a high density 2 Megabit E²PROM

comprisedoffourX28C513LCCsmountedonaco-fired

multilayered ceramic substrate. Individual components

are 100% tested prior to assembly in module form and

then 100% tested after assembly.

• High Density 2 Megabit (256K x 8) Module

• Access Time of 150ns at –55°C to +125°C

• Base Memory Component: Xicor X28C513

• Pinout conforms to JEDEC Standard for

2 Megabit E²PROM

• Fast Write Cycle Times

The XM28C020 is configured 256K x 8 bit. The module

supports a 128-byte page write operation. This com-

binedwithDATAPollingorToggleBitPolling,effectively

provides a 39µs/byte write cycle, enabling the entire

array to be rewritten in 10 seconds.

—128 Byte Page Write

—Byte or Page Write Cycle: 5ms Typical

—Complete Memory Rewrite: 10 Seconds

• Early End of Write Detection

—DATA Polling

—Toggle Bit Polling

• Software Data Protection

• Three Temperature Ranges

—Commercial: 0°C to +75°C

—Industrial: –40° to +85°C

The XM28C020 provides the same high endurance and

data retention as the X28C513.

—Military: –55° to +125°C

• High Rel Module

—100% MIL-STD-883 Compliant Components

• Endurance: 100,000 Cycles
