System

PSD8XX Family

The PSD8XX series is supported by PSDsoft a Windows-based (95, 98, NT) software

development tool. A PSD design is quickly and easily produced in a point and click

environment. The designer does not need to enter Hardware Definition Language (HDL)

equations (unless desired) to define PSD pin functions and memory map information. The

general design flow is shown in Figure 2 below. PSDsoft is available from our web site

(www.st.com/psm) or other distribution channels.

PSDsoft directly supports two low cost device programmers from ST. PSDpro

and FlashLINK (JTAG). Both of these programmers may be purchased through your local

rep/distributor, or directly from our web site using a credit card. The PSD8XX is also

supported by third party device programmers, see web site for current list.
