Introduction
Programmable Peripheral
PSD3XX Family
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.

Key Features
t Single-chip programmable peripheral for microcontroller-based applications
t 256K to 1 Mbit of UV EPROM with the following features:
• Configurable as 32, 64, or 128 K x 8; or as 16, 32, or 64 K x 16
• Divided into eight equally-sized mappable blocks for optimized address mapping
• As fast as 70 ns access time, which includes address decoding
t Optional 16 Kbit SRAM is configurable as 2K x 8 or 1K x 16. The access time can be
as quick as 70 ns, including address decoding.
t 19 I/O pins that can be individually configured for :
• Microcontroller I/O port expansion
• Programmable Address decoder (PAD) I/O
• Latched address output
• Open-drain or CMOS output
t Two Programmable Arrays (PAD A and PAD B) replace your PLD or decoder, and have
the following features:
• Up to 18 Inputs and 24 outputs
• 40 Product terms (13 for PAD A and 27 for PAD B)
• Ability to decode up to 1 MB of address without paging
t Microcontroller logic that eliminates the need for external “glue logic” has the following
features:
• Ability to interface to multiplexed and non-multiplexed buses
• Built-in address latches for multiplexed address/data bus
• ALE and Reset polarity are programmable (Reset polarity not programmable on
V-versions)
• Multiple configurations are possible for interface to many different microcontrollers
t Optional built-in page logic expands the MCU address space by up to 16 times
t Programmable power management with standby current as low as 1µA for low-voltage
version
• CMiser bit —programmable option to reduce AC power consumption in memory
• Turbo Bit (ZPSD only)—programmable bit to reduce AC and DC power consumption
in the PADs.
t Track Mode that allows other microcontrollers or host processors to share access to the
local data bus
t Built-in security locks the device and PAD decoding configuration
t Wide Operating Voltage Range
• V-versions: 2.7 to 5.5 volts
• Others: 4.5 to 5.5 volts
t Available in a variety of packaging (44-pin PLDCC, CLDCC, TQFP, and PQFP)
t Simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC.
