Preliminary Information
PSD8XXF Family
9.0
The
PSD8XXF
Functional
Blocks
As shown in Figure 1, the PSD8XXF consists of six major types of functional blocks:
Memory Blocks
PLD Blocks
Bus Interface
I/O Ports
Power Management Unit
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 PSD8XXF has the following memory blocks:
The main Flash memory
Flash boot memory
Optional 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 PSD8XXF contain which memory blocks.

Table 8. Memory Blocks
9.1.1 Main Flash and Flash Boot Memory Description
The main Flash memory block is divided evenly into eight sectors. The Flash Boot 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 Configuration.
