Key Features
t Two Zero-power Programmable Logic Devices (ZPLDs): the Decode PLD (DPLD) and
the General-purpose PLD (GPLD) can be used for:
Up to 59 Input and 126 output product terms
24 Macrocells and I/O
Decode up to 16 MB of address
State machines and state logic
Generate external signals (chip selects, bus interface, etc.)
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
Multiple configurations are possible for interface to many different microcontrollers
t Page logic is connected to the ZPLDs and expands the MCU address space to up to
16 times
t Programmable power management allows:
SRAM, EPROM, and ZPLDs to enter standby mode automatically
Disabling of the clock input to the ZPLDs
ZPLDs to enter a special low power mode (Sleep Mode), based on Turbo bit setting
t A security bit prevents reading the PSD4XX configuration and the ZPLD contents.
Setting this bit will prevent the device from being copied on a device programmer.
t Built-in security enables the user to block read accesses from a device programmer
t Package choices include 68-pin PLCC, 68-pin CLDCC, and 80-pin TQFP
t Programmable polarity Reset output (includes hysteresis), based on Reset input
t Simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC.

Notation
Throughout this data sheet, references are made to the PSD4XX. In most cases, these
references also cover the ZPSD4XX and ZPSD4XXV products. Exceptions will be noted.
The main difference between the ZPSD4XX and the PSD4XX is the standby current (Isb).
The ZPSD4XX devices have been rated for a lower standby current. Also, there is no
low-voltage version of the PSD4XX. There is only the low-voltage version of the ZPSD4XX,
which has a V suffix.
Portable and battery powered systems have recently become major embedded control
application segments. As a result, the demand for electronic components having extremely
low power consumption has increased dramatically. Recognizing this need, WSI, Inc.
has developed a new Zero Power technology. PSD4XX products virtually eliminate the DC
component of power consumption reducing it to standby levels. Eliminating the DC
component is the basis for the words “Zero Power”. PSD4XX products also minimize the
AC power component when the chip is changing states. The result is a programmable
microcontroller peripheral family that replaces discrete circuit functions while drawing
minimal current.
