PSD3XX Famly
2-11
Programmable
Address
Decoder (PAD)
The PSD3XX consists of two programmable arrays referred to as PAD A and PAD B
(Figure 3). PAD A is used to generate chip select signals derived from the input address to
the internal EPROM blocks, SRAM, I/O ports, and Track Mode signals. All its I/O functions
are listed in Table 3 and shown in Figure 3. PAD B outputs to Ports B and C for off-chip
usage.
PAD B can also be used to extend the decoding to select external devices or as a random
logic replacement. The input bus to both PAD A and PAD B is the same. By using the
PSDsoft Development Tools software, each programmable bit in the PAD array can have
one of three logic states of 0, 1, and don’t care (X). In a user’s logic design, both PADs can
share the same inputs, using the X for input signals that are not supposed to affect other
functions. The PADs use reprogrammable CMOS EPROM technology and can be
programmed and erased (if using windowed packages) by the user.
