Overview
XM28C020 2 Megabit Module XM28C020 5 Volt, Byte Alterable E2PROM DESCRIPTION 256K x 8 Bit TYPICAL FEATURES • • • • • • • • • • 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 —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 —Military: –55° to +125°C High Rel Module —100% MIL-STD-883 Compliant Components Endurance: 100,000 Cycles The XM28C020 is a high density 2 Megabit E2PROM comprised of four X28C513 LCCs mounted on a co-fired multilayered ceramic substrate.
Individual components are 100% tested prior to assembly in module form and then 100% tested after assembly.
The XM28C020 is configured 256K x 8 bit.
The module supports a 128-byte page write operation.
This combined with DATA Polling or Toggle Bit Polling, effectively provides a 39µs/byte write cycle, enabling the entire array to be rewritten in 10 seconds.
The XM28C020 provides the same high endurance and data retention as the X28C513.
