GENERAL DESCRIPTION
The WS27C010L is a performance oriented 1 Meg UV Erasable Electrically Programmable Read Only Memory
organized as 128K words x 8 bits/word. It is manufactured using an advanced CMOS technology which enables it to
operate at data access times as fast as 120 nsecs. The memory was designed utilizing WSI's patented self-aligned
split gate EPROM cell, resulting in a low power device with a very cost effective die size.
The WS27C010L 1 Meg EPROM provides extensive code store capacity for microprocessor, DSP, and
microcontroller-based systems. Its 120 nsec access time over the full Military temperature range provides the
potential of no-wait state operation. And where this parameter is important, the WS27C010L provides the user with
a very fast 35 nsec T
OE
output enable time.
The WS27C010L is offered in both a 32 pin 600 mil CERDIP, and a 32 pad Ceramic Leadless Chip Carrier
(CLLCC) for surface mount applications. Its standard JEDEC EPROM pinouts provide for automatic upgrade
density paths for existing 128K and 256K EPROM users.
