NM27C128
131,072-Bit (16K x 8) High Performance CMOS EPROM
General Description
The NM27C128 is a high performance 128K UV Erasable Electri-
cally Programmable Read Only Memory. It is manufactured with
Fairchild’s latest CMOS split gate EPROM technology which
enables it to operate at speeds as fast as 90 ns access time over
the full operating range.
The NM27C128 provides microprocessor-based systems exten-
sive storage capacity for large portions of operating system and
application software. Its 90 ns access time provides high speed
operation with high-performance CPUs. The NM27C128 offers a
single chip solution for the code storage requirements of 100%
firmware-based equipment. Frequently-used software routines
are quickly executed from EPROM storage, greatly enhancing
system utility.
The NM27C128 is configured in the standard EPROM pinout
which provides an easy upgrade path for systems which are
currently using standard EPROMs.
The NM27C128 is one member of a high density EPROM Family
which range in densities up to 4 Mb.

Note 11: Fairchild’s standard product warranty applies to devices programmed to specifications described herein.
Note 12: VCC must be applied simultaneously or before VPP and removed simultaneously or after VPP. The EPROM must not be inserted into or removed from a board with
voltage applied to VPP or VCC.
Note 13: The maximum absolute allowable voltage which may be applied to the VPP pin during programming is 14V. Care must be taken when switching the VPP supply to
prevent any overshoot from exceeding this 14V maximum specification. At least a 0.1 µF capacitor is required across VPP, VCC to GND to suppress spurious voltage transients
which may damage the device.
Note 14: During power up the PGM pin must be brought high (≥ VIH) either coincident with or before power is applied to VPP.
