DESCRIPTION
The XM28C040 is a high density 4 Megabit E2PROM
comprised of four X28C010's 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 XM28C040 is configured 512K x 8 bit. The module
supports a 256-byte page write operation. This com-
bined 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 XM28C040 provides the same high endurance and
data retention as the X28C010.
