DESCRIPTION
The M27C2001 is a high speed 2 Megabit UV
erasable and electrically programmable EPROM
ideally suited for microprocessor systems requiring
large programs. It is organised as 262,144 by 8 bits.
The Window Ceramic Frit-Seal Dual-in-Line and
Leadless Chip Carrier packages have transparent
lids which allow the user to expose the chip to
ultraviolet light to erase the bit pattern. A new
pattern can then be written to the device by follow-
ing the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C2001 is offered in both Plastic Leaded Chip
Carrier and Plastic Thin Small Outline packages.
