Development system
The PSD family is supported by PSDsoft Express, a Windows-based software development
tool (Windows-95, Windows-98, Windows-2000, Windows-NT). A PSD design is quickly and
easily produced in a point and click environment. The designer does not need to enter
Hardware Description Language (HDL) equations, unless desired, to define PSD pin
functions and memory map information. The general design flow is shown in
PSDsoft Express is available from our web site (the address is given on the back page of
this data sheet) or other distribution channels.
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.
