Product Details

Description



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 register to the array
• 192 product terms with variable distribution to macrocells
• 13 inputs, 12 feedback I/O pins, plus 6 shared I/O macrocell feedbacks for a total of 31 true and complementary inputs
• High speed: 20 ns maximum tPD
• Security bit
• Space-saving 28-pin slim-line DIP package; also available in 28-pin PLCC
• Low power
    -90 mA typical ICC quiescent
   -180 mA ICC maximum
   -UV-erasable and reprogrammable
  -Programming and operation 100% testable

Description

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