ZPSD303V-15J description
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 parts 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. |
