DESCRIPTION

The

word by 8-bit) Ultraviolet Erasable CMOS Programmable

Read-Only Memory. It utilizes the standard JEDEC pinout

making it functionally compatible with the IS27C010, but with

significantly faster access capability. This superior random

access capability results from a focused high-speed design.

This offers users bipolar speeds with higher density, lower

cost, and proven reliability.

The device is ideal for use with the faster processors. Design-

ers may take full advantage of high-speed digital signal

processors and microprocessors by allowing code to be

executed at full speed directly out of EPROM. Typical applica-

tions include laser printers, switching networks, graphics,

workstations, high-speed modems, and digital signal process-

ing.

The IS27HC010 uses

which allows the entire chip to be programmed in typically less

than 30 seconds.

This product is available inOne-Time Programmable (OTP)

PDIP, PLCC, and TSOP packages over commercial and

industrial temperature ranges.
