General Description
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.
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.
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.
Ultra37000 5.0V Devices
The Ultra37000 devices operate with a 5V supply and can
support 5V or 3.3V I/O levels. V
CCO
connections provide the
capability of interfacing to either a 5V or 3.3V bus. By
connecting the V
CCO
pins to 5V the user insures 5V TTL levels
on the outputs. If V
CCO
is connected to 3.3V the output levels
meet 3.3V JEDEC standard CMOS levels and are 5V tolerant.
These devices require 5V ISR programming.
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.
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.
