2K x 8 Dual-Port Static RAM
Features
■ True dual-ported memory cells that enable simultaneous reads of the same memory location
■ 2K x 8 organization
■ 0.65 micron CMOS for optimum speed and power
■ High speed access: 15 ns
■ Low operating power: ICC = 110 mA (maximum) ■ Fully asynchronous operation
■ Automatic power-down ■ Master CY7C132/CY7C136/CY7C136A[1] easily expands data
bus width to 16 or more bits using slave CY7C142/CY7C146
■ BUSY output flag on CY7C132/CY7C136/CY7C136A; BUSY input on CY7C142/CY7C146
■ INT flag for port to port communication (52-Pin PLCC/PQFP versions)
■ CY7C136, CY7C136A, and CY7C146 available in 52-pin PLCC and 52-pin PQFP packages
■ Pb-free packages available
Functional Description
The CY7C132, CY7C136, CY7C136A, CY7C142, and CY7C146 are high speed CMOS 2K x 8 dual-port static RAMs. Two ports are provided to permit independent access to any location in memory. The CY7C132, CY7C136, and C...
