CY7C346B
128-Macrocell MAX® EPLD
Features
The 128 macrocells in the CY7C346B are divided into eight
LABs, 16 per LAB. There are 256 expander product terms, 32
per LAB, to be used and shared by the macrocells within each
LAB.
• 128 macrocells in eight logic array blocks (LABs)
• 20 dedicated inputs, up to 64 bidirectional I/O pins
Each LAB is interconnected through the programmable interconnect array, allowing all signals to be routed throughout the
chip.
• Programmable interconnect array
• Advanced 0.65-micron CMOS technology to increase
performance
• Available in 84-pin CLCC, PLCC, and 100-pin PGA,
PQFP
Functional Description
The CY7C346B is an Erasable Programmable Logic Device
(EPLD) in which CMOS EPROM cells are used to configure
logic functions within the device. The MAX® architecture is
100% user-configurable, allowing the device to accommodate
a variety of independent logic functions.
The speed and density of the CY7C346B allow it to be used in
a wide range of applications, from replacement of large
amounts of 7400-series TTL logic, to complex controllers and
multifunction chips. With greater than 25 times the functionality
of 20-pin PLDs, the CY7C346B allows the replacement of over
50 TTL CY7C346B. By replacing large amounts of logic, the
CY7C346B reduces board space, part count, and increases
system reliability.

Logic Array Blocks
Externally, the CY7C346B provides 20 dedicated inputs, one
of which may be used as a system clock. There are 64 I/O pins
that may be individually configured for input, output, or bidirectional data flow.
There are eight logic array blocks in the CY7C346B. Each LAB
consists of a macrocell array containing 16 macrocells, an
expander product term array containing 32 expanders, and an
I/O block. The LAB is fed by the programmable interconnect
array and the dedicated input bus. All macrocell feedbacks go
to the macrocell array, the expander array, and the programmable interconnect array. Expanders feed themselves and the
macrocell array. All I/O feedbacks go to the programmable
interconnect array so that they may be accessed by macrocells in other LABs as well as the macrocells in the LAB in
which they are situated.
Programmable Interconnect Array
The Programmable Interconnect Array (PIA) solves interconnect limitations by routing only the signals needed by each
logic array block. The inputs to the PIA are the outputs of every
macrocell within the device and the I/O pin feedback of every
pin on the device.

Design Recommendations
Operation of the devices described herein with conditions
above those listed in the “Maximum Ratings” section of this
datasheet may cause permanent damage to the device. This
is a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operational sections of this data sheet is not implied. Exposure
to absolute maximum ratings conditions for extended periods
of time may affect device reliability. The CY7C346B contains
circuitry to protect device pins from high static voltages or
electric fields, but normal precautions should be taken to avoid
application of any voltage higher than the maximum rated
voltages.
For proper operation, input and output pins must be
constrained to the range GND ≤ (VIN or VOUT) ≤ VCC. Unused
inputs must always be tied to an appropriate logic level
(either VCC or GND). Each set of VCC and GND pins must
Document #: 38-03037 Rev. *C
be connected directly at the device. Power supply
decoupling capacitors of at least 0.2 µF must be connected
between VCC and GND. For the most effective decoupling,
each VCC pin should be separately decoupled to GND
directly at the device. Decoupling capacitors should have
good frequency response, such as monolithic ceramic types
have.
Design Security
The CY7C346B contains a programmable design security
feature that controls the access to the data programmed into
the device. If this programmable feature is used, a proprietary
design implemented in the device cannot be copied or
retrieved. This enables a high level of design control to be
obtained since programmed data within EPROM cells is
invisible. The bit that controls this function, along with all other
Page 4 of 15
USE ULTRA37000™ FOR
ALL NEW DESIGNS
CY7C346B
program data, may be reset simply by erasing the entire
device.
Timing Considerations
The CY7C346B is fully functionally tested and guaranteed
through complete testing of each programmable EPROM bit
and all internal logic elements thus ensuring 100%
programming yield.
Unless otherwise stated, propagation delays do not include
expanders. When using expanders, add the maximum
expander delay tEXP to the overall delay. Similarly, there is an
additional tPIA delay for an input from an I/O pin when
compared to a signal from straight input pin.
The erasable nature of these devices allows test programs to
be used and erased during early stages of the production flow.
The devices also contain on-board logic test circuitry to allow
verification of function and AC specification once encapsulated in non-windowed packages.
Typical ICC vs. fMAX
When calculating external asynchronous frequencies, use
tAS1 if all inputs are on the dedicated input pins.
400
ICC ACTIVE (mA) Typ.
When calculating synchronous frequencies, use tSU if all
inputs are on dedicated input pins. When expander logic is
used in the data path, add the appropriate maximum expander
delay, tEXP to tSU. Determine which of 1/(tWH + tWL), 1/tCO1,
or 1/(tEXP + tSU) is the lowest frequency. The lowest of these
frequencies is the maximum data path frequency for the
synchronous configuration.
When expander logic is used in the data path, add the
appropriate maximum expander delay, tEXP to tAS1.
Determine which of 1/(tAWH + tAWL), 1/tACO1, or 1/(tEXP +
tAS1) is the lowest frequency. The lowest of these
frequencies is the maximum data path frequency for the
asynchronous configuration.

The parameter tOH indicates the system compatibility of this
device when driving other synchronous logic with positive
input hold times, which is controlled by the same
synchronous clock. If tOH is greater than the minimum
required input hold time of the subsequent synchronous
logic, then the devices are guaranteed to function properly
with a common synchronous clock under worst-case
environmental and supply voltage conditions.

2. The Voltage on any input or I/O pin cannot exceed the power pin during power-up.
3. The IOH parameter refers to high-level TTL output current; the IOL parameter refers to low-level TTL output current.

Notes:
4. C1 = 35 pF.
5. The fMAX values represent the highest frequency for pipeline data.
6. This parameter is measured with a 16-bit counter programmed into each LAB.
7. This parameter is measured with a positive-edge-triggered clock at the register. For negative-edge clocking, the tACH and tACL parameter must be swapped.
8. C1 = 5 pF.
