DESCRIPTION

PLCC44 (K)

The M27C202 is a 2 Mbit EPROM offered in the

two ranges UV (ultra violet erase) and OTP (one

time programmable). It is ideally suited for micro-

processor systems requiring large programs, in

the application where the contents is stable and

needs to be programmed only one time, and is or-

ganised as 131,072 by 16 bits.

Figure 1. Logic Diagram

The FDIP40W (window ceramic frit-seal package)

has a transparent lids which allow the user to ex-

pose the chip to ultraviolet light to erase the bit pat-

tern. A new pattern can then be written to the

device by following the programming procedure.

For applications where the content is programmed

only one time and erasure is not required, the

M27C202 is offered in PDIP40, PLCC44 and

TSOP40 (10 x 14 mm) packages.
