Functional Description
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: 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.
