PSD GPLD PRIMER - PSD6XX/7XX/8XX
Application Note 055

Abstract
A PSD (Programmable System Device) is a peripheral device, which provides memory, logic, I/O, and
other functions to a microcontroller unit (MCU). Internally, the PSD is a collection of programmable logic
surrounding both volatile and non-volatile memory (NVM). Some of this logic is dedicated to specific
MCU functions, such as bus interfacing, address demultiplexing, and address decoding.
Much of the remaining logic is not dedicated to MCU interfacing, making it available to solve user design
problems. The block that can be used for general logic functions is called the General PLD (GPLD). The
GPLD is comprised of Input MicroCells (IMCs), Output MicroCells (OMCs), and an AND array. The
GPLD is very closely tied to the I/O ports as well. Many of the elements in the GPLD are directly
accessible by the MCU without extra design effort from the system designer. The central focus of this
document is based on the GPLD portion of the PSD.
This document is applicable to the PSD6XX, PSD7XX, and PSD8XX PSD families. The general
architecture of the GPLD in these devices is very similar.
Appendix A consists of a sample design based on a PSD611. This design highlights many features and is
referenced by line number and signal name throughout this primer.
