CY7C132, CY7C136 CY7C136A, CY7C142, CY7C146 2K x 8 Dual-Port Static RAM Features ■ ■ ■ ■ ■ ■ ■ ■ ■ 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 CY7C136A can be used as either a standalone 8-bit dual-port static RAM or as a MASTER dual-port RAM, in conjunction with the CY7C142/CY7C146 SLAVE dual-port device. They are used in systems that require 16-bit or greater word widths. This is the solution to applications that require shared or buffered data, such as cache memory for DSP, bit-slice, or multiprocessor designs. Each port has independent control pins; chip enable (CE), write enable (R/W), and output enable (OE). BUSY flags are provided on each port. In addition, an interrupt flag (INT) is provided on each port of the 52-pin PLCC version. BUSY signals that the port is trying to access the same location currently being accessed by the other port. On the PLCC version, INT is an interrupt flag indicating that data is placed in an unique location (7FF for the left port and 7FE for the right port). An automatic power down feature is controlled independently on each port by the chip enable (CE) pins. 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 ■ ■ ■ Logic Block Diagram R/WL CEL OEL R/WR CER OER I/O7L I/O0L BUSYL I/O CONTROL I/O CONTROL I/O7R I/O0R BUSYR [2] MEMORY ARRAY [2] A 10L A 0L ADDRESS DECODER ADDRESS DECODER A 10R A 0R CEL OEL R/WL INTL[3] ARBITRATION LOGIC (7C132/7C136 ONLY) AND INTERRUPTLOGIC (7C136/7C146 ONLY) CER OER R/WR INTR [3] Notes 1.

The data input setup and hold timing must be referenced to the rising edge of the signal that terminates the write. 13. These parameters are measured from the input signal changing, until the output pin goes to a high impedance state. 14. CY7C142/CY7C146 only. 15.
