Preliminary Information
PSD9XX Family
9.0
The
PSD9XX
Functional
Blocks
As shown in Figure 1, the PSD9XX consists of six major types of functional blocks:
t Memory Blocks
t PLD Blocks
t Bus Interface
t I/O Ports
t Power Management Unit
t JTAG Interface
The functions of each block are described in the following sections. Many of the blocks
perform multiple functions, and are user configurable.
9.1 Memory Blocks
The PSD9XX has the following memory blocks:
The main Flash memory
Secondary Flash memory
SRAM.
The memory select signals for these blocks originate from the Decode PLD (DPLD) and
are user-defined in PSDsoft.
Table 8 summarizes which versions of the PSD9XX contain which memory blocks.

Table 8. Memory Blocks
9.1.1 Main Flash and Secondary Flash Memory Description
The main Flash memory block is divided evenly into eight sectors. The secondary Flash
memory is divided into four sectors of eight Kbytes each. Each sector of either memory
can be separately protected from program and erase operations.
Flash memory may be erased on a sector-by-sector basis and programmed byte-by-byte.
Flash sector erasure may be suspended while data is read from other sectors of memory
and then resumed after reading.
During a program or erase of Flash, the status can be output on the Rdy/Bsy pin of Port
C3. This pin is set up using PSDsoft.
