DESCRIPTION
The ISSI IS27HC010 is an ultra-high-speed 1 megabit (128K-
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 ISSI's write programming algorithm
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.
