Introduction
Programmable Peripheral
PSD3XX Famly
Field-Programmable Microcontroller Peripheral
The low cost PSD3XX family integrates high-performance and user-configurable blocks of
EPROM, programmable logic, and optional SRAM into one part. The PSD3XX products
also provide a powerful microcontroller interface that eliminates the need for external
“glue logic”. The part’s integration, small form factor, low power consumption, and ease of
use make it the ideal part for interfacing to virtually any microcontroller.
The major functional blocks of the PSD3XX include:
Two programmable logic arrays
256Kb to 1 Mb of EPROM
Optional 16 Kb SRAM
Input latches
Programmable I/O ports
Page logic
Programmable security.
The PSD3XX family architecture (Figure 1) can efficiently interface with, and enhance,
almost any 8- or 16-bit microcontroller system. This solution provides microcontrollers the
following:
Chip-select logic, control logic, and latched address signals that are otherwise
implemented discretely
Port expansion (reconstructs lost microcontroller I/O)
Expanded microcontroller address space (up to 16 times)
An EPROM (with security) and optional SRAM
Compatible with 8031-type architectures that use separate Program and Data Space
Interface to shared external resources.
