DEVELOPMENT SYSTEM

The PSD family is supported by PSDsoft, a Win-

dows-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 Description Lan-

guage (HDL) equations, unless desired, to define

PSD pin functions and memory map information.

The general design flow is shown in Figure 4. PS-

Dsoft is available from our web site (the address is

given on the back page of this data sheet) or other

distribution channels.

PSDsoft directly supports two low cost device pro-

grammers form ST: PSDpro and FlashLINK

(JTAG). Both of these programmers may be pur-

chased through your local distributor/representa-

tive, or directly from our web site using a credit

card. The PSD is also supported by third party de-

vice programmers. See our web site for the current

list.
