DESCRIPTION

The M27C4002 is a 4 Mbit EPROM offered in the

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

time programmable). It is ideally suited for micro-

processorsystemsrequiring large programsand is

organised as 262,144 words of 16 bits.

TSOP40 (N)

10 x 20 mm

The FDIP40W (window ceramic frit-seal package)

and the JLCC44W (J-lead chip carrier packages)

have transparent lids which allow the user to ex-

pose the chip to ultraviolet light to erase the bit

pattern. A new pattern can then be written to the

device by following the programming procedure.

Figure 1. Logic Diagram

For applications wherethe content is programmed

only one time and erasure is not required, the

M27C4002 is offered in PDIP40, PLCC44 and

TSOP40 (10 x 20 mm) packages.
