Description

The PSD935G2 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 PSD935G2 is also supported by third party device programmers, see web site for current list.
