M28F020
2048K (256K x 8) CMOS Flash Memory
Intel’s M28F020 CMOS flash memory offers the most cost-effective and reliable alternative for read/write
random access nonvolatile memory. The M28F020 adds electrical chip-erasure and reprogramming
to familiar EPROM technology. Memory contents can be rewritten: in a test socket; in a PROM-
programmer socket; onboard during subassembly test; in-system during final test; and in-system after-
sale. The M28F020 increases memory flexibility, while contributing to time- and cost-savings.
The M28F020 is a 2048-kilobit nonvolatile memory organized as 262,144 bytes of 8 bits. Intel’s
M28F020 is offered in 32-pin ceramic DIP, and 32-lead Flatpack packages. Pin assignments conform to
JEDEC standards for byte-wide EPROMs.
