Description
256k Chip Erase Flash Memory
Manufacturer
STMicroelectronics
Datasheet
DESCRIPTION
The M28F201 FLASH Memory product is a non-
volatile memories which may be erased electrically
at the chip level and programmed byte-by-byte. It
is organised as 256K bytes. It uses a command
register architecture to select the operating modes
and thus provide a simple microprocessor inter-
face. The M28F201 FLASH Memory product is
suitable for applications where the memory has to
be reprogrammed in the equipment. The access
time of 70ns makes the device suitable for use in
high speed microprocessor systems.
