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 prod-
uct term array, product term allocator, and 16 macrocells. The
PIM distributes signals from the logic block outputs and all in-
put 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 fea-
ture provides the ability to reconfigure the devices without hav-
ing design changes cause pinout or timing changes. The
Cypress ISR function is implemented through a JTAG-compli-
ant 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 simultaneously
fixing pinout assignments and maintaining system perfor-
mance.
The entire family features JTAG for ISR and boundary scan,
and is compatible with the PCI Local Bus specification, meet-
ing 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 sup-
port 5V or 3.3V I/O levels. V
CCO
connections provide the ca-
pability 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.
