CY7C331 Datasheet Asynchronous Registered Epld

Manufacturer: Cypress (now Infineon)

Overview: 1CY7C331 fax id: 6016 CY7C331 .. Asynchronous Registered EPLD.

General Description

The CY7C331 is the most versatile PLD available for asynchronous designs.

Central resources include twelve full D-type flip-flops with separate set, reset, and clock capability.

For increased utility, XOR gates are provided at the D-inputs and the product term allocation per flip-flop is variably distributed.

Key Features

  • Twelve I/O macrocells each having:.
  • One state flip-flop with an XOR sum-of-products input.
  • One feedback flip-flop with input coming from the I/O pin.
  • Independent (product term) set, reset, and clock inputs on all registers.
  • Asynchronous bypass capability on all registers under product term control (r = s = 1).
  • Global or local output enable on three-state I/O.
  • Feedback from either registe.
