DESCRIPTION
The XM28C020 is a high density 2 Megabit E
2
PROM
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 com-
bined with
DATA
Polling or Toggle Bit Polling, effectively
provides a 39
μ
s/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.
