PSD6XX Family

The PSD6XXE1
Functional
Blocks
The PSD6XXE1 consists of five major functional blocks:
J
PLD Block
J
Bus Interface
J
I/O Ports
J
Memory Block
J
Power Management Unit
The functions of each block are described in the following sections. Many of the blocks
perform multiple functions, and are user configurable.
PLDs
The PLDs bring programmable logic functionality to the PSD6XXE1. After
specifying the logic for the PLDs by using the PSDabel tool in the PSDsoft suite, the logic
configuration is programmed into the device and available when power is applied.
The PLDs (DPLD, ECSPLD and GPLD) consist of an AND array. The GPLD architecture
includes 12 Output Micro
Cells in addition to the AND array. There are 23 Input
Micro
Cells that can be configured as inputs to the PLD. Figure 3 shows the organization
of the PLD.
The AND array is used to form product terms specified using the PSDabel tool in the
PSDsoft development system. When the inputs used in a term are true, the output is active.
The GPLD Input Bus consists of 63 signals as shown in Table 6. Both the true and
complement value of inputs are available to the AND array. The DPLD and ECSPLD Input
Busses consists of fewer inputs and is a subset of the 63 inputs.
