CY7C133

CY7C143

2K x 16 Dual-Port Static RAM

Features

Functional Description

• True dual-ported memory cells which allow

The CY7C133 and CY7C143 are high-speed CMOS 2K by 16

dual-port static RAMs. Two ports are provided permitting

independent access to any location in memory. The CY7C133

can be utilized as either a stand-alone 16-bit dual-port static

RAM or as a master dual-port RAM in conjunction with the

CY7C143 slave dual-port device in systems requiring 32-bit or

greater word widths. It is the solution to applications requiring

shared or buffered data, such as cache memory for DSP,

bit-slice, or multiprocessor designs.

simultaneous reads of the same memory location

• 2K x 16 organization

• 0.65-micron CMOS for optimum speed/power

• High-speed access: 25/35/55 ns

• Low operating power: I_CC= 150 mA (typ.)

• Fully asynchronous operation

• Master CY7C133 expands data bus width to 32 bits or

more using slave CY7C143

• BUSY output flag on CY7C133; BUSY input flag on

CY7C143

• Available in 68-pin PLCC

Each port has independent control pins; Chip Enable (CE),

Write Enable (R/W_UB, R/W_LB), and Output Enable (OE).

BUSY signals that the port is trying to access the same

location currently being accessed by the other port. An

automatic power-down feature is controlled independently on

each port by the Chip Enable (CE) pin.

The CY7C133 and CY7C143 are available in 68-pin PLCC.
