DEVELOPMENT SYSTEM

The PSD family is supported by PSDsoft Express,

a Windows-based software development tool

(Windows-95, Windows-98, Windows-2000, Win-

dows-NT). A PSD design is quickly and easily pro-

duced in a point and click environment. The

designer does not need to enter Hardware De-

scription Language (HDL) equations, unless de-

sired, to define PSD pin functions and memory

map information. The general design flow is

shown in Figure 5. PSDsoft Express is available

from our web site (the address is given on the back

page of this data sheet) or other distribution chan-

nels.

PSDsoft Express directly supports two low cost

device programmers form ST: PSDpro and

FlashLINK (JTAG). Both of these programmers

may be purchased through your local distributor/

representative, or directly from our web site using

a credit card. The PSD is also supported by thid

party device programmers. See our web site for

the current list.
