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.
