Ultra37000 CPLD Family

5V, 3.3V, ISR™ High-Performance CPLDs

Features

General Description

• In-System Reprogrammable™ (ISR™) CMOS CPLDs

— JTAG interface for reconfigurability

— Design changes do not cause pinout changes

— Design changes do not cause timing changes

• High density

The Ultra37000™ family of CMOS CPLDs provides a range of

high-density programmable logic solutions with unparalleled

system performance. The Ultra37000 family is designed to

bring the flexibility, ease of use, and performance of the 22V10

to high-density CPLDs. The architecture is based on a number

of logic blocks that are connected by a Programmable Inter-

connect Matrix (PIM). Each logic block features its own

product term array, product term allocator, and 16 macrocells.

The PIM distributes signals from the logic block outputs and all

input pins to the logic block inputs.

— 32 to 512 macrocells

— 32 to 264 I/O pins

— Five dedicated inputs including four clock pins

• Simple timing model

All of the Ultra37000 devices are electrically erasable and In-

System Reprogrammable (ISR), which simplifies both design

and manufacturing flows, thereby reducing costs. The ISR

feature provides the ability to reconfigure the devices without

having design changes cause pinout or timing changes. The

Cypress ISR function is implemented through a JTAG-

compliant serial interface. Data is shifted in and out through

the TDI and TDO pins, respectively. Because of the superior

routability and simple timing model of the Ultra37000 devices,

ISR allows users to change existing logic designs while simul-

taneously fixing pinout assignments and maintaining system

performance.

— No fanout delays

— No expander delays

— No dedicated vs. I/O pin delays

— No additional delay through PIM

— No penalty for using full 16 product terms

— No delay for steering or sharing product terms

• 3.3V and 5V versions

• PCI-compatible^[1]

• Programmable bus-hold capabilities on all I/Os

• Intelligent product term allocator provides:

— 0 to 16 product terms to any macrocell

The entire family features JTAG for ISR and boundary scan,

and is compatible with the PCI Local Bus specification,

meeting the electrical and timing requirements. The

Ultra37000 family features user programmable bus-hold

capabilities on all I/Os.

— Product term steering on an individual basis

— Product term sharing among local macrocells

• Flexible clocking

Ultra37000 5.0V Devices

The Ultra37000 devices operate with a 5V supply and can

support 5V or 3.3V I/O levels. V_CCOconnections provide the

capability of interfacing to either a 5V or 3.3V bus. By

connecting the V_CCOpins to 5V the user insures 5V TTL levels

on the outputs. If V_CCOis connected to 3.3V the output levels

meet 3.3V JEDEC standard CMOS levels and are 5V tolerant.

These devices require 5V ISR programming.

— Four synchronous clocks per device

— Product term clocking

— Clock polarity control per logic block

• Consistent package/pinout offeringacrossall densities

— Simplifies design migration

— Same pinout for 3.3V and 5.0V devices

• Packages

Ultra37000V 3.3V Devices

Devices operating with a 3.3V supply require 3.3V on all V_CCO

pins, reducing the device’s power consumption. These

devices support 3.3V JEDEC standard CMOS output levels,

and are 5V-tolerant. These devices allow 3.3V ISR

programming.

— 44 to 400 leads in PLCC, CLCC, PQFP, TQFP, CQFP,

BGA, and Fine-Pitch BGA packages

Note:

1. Due to the 5V-tolerant nature of 3.3V device I/Os, the I/Os are not clamped to V_CC, PCI V_IH= 2V.
