Functional Description
— Output enable (OE) multiplexer
Bypass on input and output registers
All twelve macrocell state registers can be hidden
User configurable I/O macrocells to implement JK or
RS flip-flops and T or D registers
Input multiplexer per pair of I/O macrocells allows I/O
pin associated with a hidden macrocell state register
to be saved for use as an input
Four dedicated hidden registers
Twelve dedicated registered inputs with individually
programmable bypass option
Three separate clocks—two input clocks, two output
clocks
Common (pin 14-controlled) or product term-controlled
output enable for each I/O pin
256 product terms—32 per pair of macrocells, variable
distribution
Global, synchronous, product term-controlled, state
register set and reset—inputs to product term are
clocked by input clock
The CY7C335 is a high-performance, erasable, programmable logic device (EPLD) whose architecture has been optimized to enable the user to easily and efficiently construct very
high performance state machines.
The architecture of the CY7C335, consisting of the user-configurable output macrocell, bidirectional I/O capability, input
registers, and three separate clocks, enables the user to design high-performance state machines that can communicate
either with each other or with microprocessors over bidirectional parallel buses of user-definable widths.
The four clocks permit independent, synchronous state machines to be synchronized to each other.
The user-configurable macrocells enable the designer to designate JK-, RS-, T-, or D-type devices so that the number of
product terms required to implement the logic is minimized.
The CY7C335 is available in a wide variety of packages including 28-pin, 300-mil plastic and ceramic DIPs, PLCCs, and
LCCs.

Notes:
1. tA is the “instant on” case temperature.
2. See the last page of this specification for Group A subgroup testing information.
3. These are absolute values with respect to device ground and all overshoots due to system or tester noise are included.
4. Not more than one output should be tested at a time. Duration of the short circuit should not be more than one second. V OUT = 0.5V has been chosen to avoid
test problems caused by ground degradation.
5. Tested initially and after any design or process changes that may affect these parameters.

Notes:
6. This specification is intended to guarantee interface compatibility of the other members of the CY7C330 family with the CY7C335. This specification is met
for the devices operating at the same ambient temperature and at the same power supply voltage.
7. This part has been designed with the capability to reset during system power-up. Following power-up, the input and output registers will be reset to a logic
LOW state. The output state will depend on how the array is programmed.
