PSD4XX Family

2.0

Key Features

❏ 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.)

❏ 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

❏ Page logic is connected to the ZPLDs and expands the MCU address space to up to

16 times

❏ 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

❏ 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.

❏ Built-in security enables the user to block read accesses from a device programmer

❏ Package choices include 68-pin PLCC, 68-pin CLDCC, and 80-pin TQFP

❏ Programmable polarity Reset output (includes hysteresis), based on Reset input

❏ Simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC.

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.

Notation

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, ST

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.
