CY7C375i
UltraLogic™ 128-Macrocell Flash CPLD
Features
• 3.3V or 5.0V I/O operation
• Available in 160-pin TQFP, CQFP, and PGA packages
• 128 macrocells in eight logic blocks
• 128 I/O pins
Functional Description
• Five dedicated inputs including 4 clock pins
The CY7C375i is an In-System Reprogrammable Complex
Programmable Logic Device (CPLD) and is part of the
FLASH370i™ family of high-density, high-speed CPLDs. Like
all members of the FLASH370i family, the CY7C375i is
designed to bring the ease of use and high performance of the
22V10 to high-density PLDs.
• In-System Reprogrammable (ISR™) Flash technology
— JTAG Interface
• Bus Hold capabilities on all I/Os and dedicated inputs
• No hidden delays
Like all of the UltraLogic™ FLASH370i devices, the CY7C375i
is electrically erasable and In-System Reprogrammable (ISR),
which simplifies both design and manufacturing flows thereby
reducing costs. The Cypress ISR function is implemented
through a JTAG serial interface. Data is shifted in and out
through the SDI and SDO pins. The ISR interface is enabled
using the programming voltage pin (ISREN). Additionally,
because of the superior routability of the FLASH370i devices,
ISR often allows users to change existing logic designs while
simultaneously fixing pinout assignments.
• High speed
— fMAX = 125 MHz
— tPD = 10 ns
— tS = 5.5 ns
— tCO = 6.5 ns
• Fully PCI compliant

Functional Description
The 128 macrocells in the CY7C375i are divided between
eight logic blocks. Each logic block includes 16 macrocells, a
72 x 86 product term array, and an intelligent product term
allocator.
The logic blocks in the FLASH370i architecture are connected
with an extremely fast and predictable routing resource—the
Programmable Interconnect Matrix (PIM). The PIM brings
flexibility, routability, speed, and a uniform delay to the interconnect.
Like all members of the FLASH370i family, the CY7C375i is rich
in I/O resources. Every macrocell in the device features an
associated I/O pin, resulting in 128 I/O pins on the CY7C375i.
In addition, there is one dedicated input and four input/clock
pins.
Finally, the CY7C375i features a very simple timing model.
Unlike other high-density CPLD architectures, there are no
hidden speed delays such as fanout effects, interconnect
delays, or expander delays. Regardless of the number of
resources used or the type of application, the timing parameters on the CY7C375i remain the same.

Logic Block
The number of logic blocks distinguishes the members of the
FLASH370i family. The CY7C375i includes eight logic blocks.
Each logic block is constructed of a product term array, a
product term allocator, and 16 macrocells.
Product Term Array
The product term array in the FLASH370i logic block includes
36 inputs from the PIM and outputs 86 product terms to the
product term allocator. The 36 inputs from the PIM are
available in both positive and negative polarity, making the
overall array size 72 x 86. This large array in each logic block
allows for very complex functions to be implemented in single
passes through the device.
Product Term Allocator
The product term allocator is a dynamic, configurable resource
that shifts product terms to macrocells that require them. Any
number of product terms between 0 and 16 inclusive can be
assigned to any of the logic block macrocells (this is called
product term steering). Furthermore, product terms can be
shared among multiple macrocells. This means that product
terms that are common to more than one output can be implemented in a single product term. Product term steering and
Page 4 of 17
USE ULTRA37000™
FOR ALL NEW DESIGNS
product term sharing help to increase the effective density of
the FLASH370i PLDs. Note that product term allocation is
handled by software and is invisible to the user.
I/O Macrocell
Each of the macrocells on the CY7C375i has a separate I/O
pin associated with it. The input to the macrocell is the sum of
between 0 and 16 product terms from the product term
allocator. The macrocell includes a register that can be
optionally bypassed, polarity control over the input sum-term,
and four global clocks to trigger the register. The macrocell
also features a separate feedback path to the PIM so that the
register can be buried if the I/O pin is used as an input.
Programmable Interconnect Matrix
The Programmable Interconnect Matrix (PIM) connects the
eight logic blocks on the CY7C375i to the inputs and to each
other. All inputs (including feedbacks) travel through the PIM.
There is no speed penalty incurred by signals traversing the
PIM.
Programming
For an overview of ISR programming, refer to the FLASH370i
Family data sheet and for ISR cable and software specifications, refer to ISR data sheets. For a detailed description of
ISR capabilities, refer to the Cypress application note, “An
Introduction to In System Reprogramming with FLASH370i.”
PCI Compliance
The FLASH370i family of CMOS CPLDs are fully compliant with
the PCI Local Bus Specification published by the PCI Special
Interest Group. The simple and predictable timing model of
FLASH370i ensures compliance with the PCI AC specifications
independent of the design. On the other hand, in CPLD and
FPGA architectures without simple and predictable timing, PCI
compliance is dependent upon routing and product term
distribution.
Document #: 38-03029 Rev. *A
CY7C375i
3.3V or 5.0V I/O Operation
The FLASH370i family can be configured to operate in both
3.3V and 5.0V systems. All devices have two sets of VCC pins:
one set, VCCINT, for internal operation and input buffers, and
another set, VCCIO, for I/O output drivers. VCCINT pins must
always be connected to a 5.0V power supply. However, the
VCCIO pins may be connected to either a 3.3V or 5.0V power
supply, depending on the output requirements. When VCCIO
pins are connected to a 5.0V source, the I/O voltage levels are
compatible with 5.0V systems. When VCCIO pins are
connected to a 3.3V source, the input voltage levels are
compatible with both 5.0V and 3.3V systems, while the output
voltage levels are compatible with 3.3V systems. There will be
an additional timing delay on all output buffers when operating
in 3.3V I/O mode. The added flexibility of 3.3V I/O capability is
available in commercial and industrial temperature ranges.
Bus Hold Capabilities on all I/Os and Dedicated Inputs
In addition to ISR capability, a new feature called bus-hold has
been added to all FLASH370i I/Os and dedicated input pins.
Bus-hold, which is an improved version of the popular internal
pull-up resistor, is a weak latch connected to the pin that does
not degrade the device’s performance. As a latch, bus-hold
recalls the last state of a pin when it is three-stated, thus
reducing system noise in bus-interface applications. Bus-hold
additionally allows unused device pins to remain unconnected
on the board, which is particularly useful during prototyping as
designers can route new signals to the device without cutting
trace connections to VCC or GND.
Design Tools
Development software for the CY7C375i is available from
Cypress’s Warp®, Warp Professional™, and Warp Enterprise™ software packages. Please refer to the data sheets on
these products for more details. Cypress also actively
supports almost all third-party design tools. Please refer to
third-party tool support for further information.

Notes:
2. TA is the “instant on” case temperature.
3. See the last page of this specification for Group A subgroup testing information.
4. If VCCIO is not specified, the device can be operating in either 3.3V or 5V I/O mode; VCC=VCCINT.
5. IOH = –2 mA, IOL = 2 mA for SDO.
6. When the I/O is three-stated, the bus-hold circuit can weakly pull the I/O to a maximum of 4.0V if no leakage current is allowed. This voltage is lowered significantly by
a small leakage current. Note that all I/Os are three-stated during ISR programming. Refer to the application note “Understanding Bus Hold” for additional information.
7. These are absolute values with respect to device ground. All overshoots due to system or tester noise are included.
8. Not more than one output should be tested at a time. Duration of the short circuit should not exceed 1 second. VOUT = 0.5V has been chosen to avoid test
problems caused by tester ground degradation.
9. Tested initially and after any design or process changes that may affect these parameters.
10. Measured with 16-bit counter programmed into each logic block.
11. CI/O for dedicated inputs, and for I/O pins with JTAG functionality is 12 pF,and for the ISREN pin is 15 pF Max.

13. All AC parameters are measured with 16 outputs switching and 35-pF AC Test Load.
14. This specification is intended to guarantee interface compatibility of the other members of the CY7C370i family with the CY7C375i. This specification is met for
the devices operating at the same ambient temperature and at the same power supply voltage.
