CY7C1294DV18

9-Mbit QDR- II™ SRAM 2-Word

Burst Architecture

Features

Functional Description

• Separate Independent Read and Write data ports

The CY7C1292DV18 and CY7C1294DV18 are 1.8V

Synchronous Pipelined SRAMs, equipped with QDR™-II

architecture. QDR-II architecture consists of two separate

ports to access the memory array. The Read port has

dedicated Data Outputs to support Read operations and the

Write Port has dedicated Data Inputs to support Write opera-

tions. QDR-II architecture has separate data inputs and data

outputs to completely eliminate the need to “turn-around” the

data bus required with common I/O devices. Access to each

port is accomplished through a common address bus. The

Read address is latched on the rising edge of the K clock and

the Write address is latched on the rising edge of the K clock.

Accesses to the QDR-II Read and Write ports are completely

independent of one another. In order to maximize data

throughput, both Read and Write ports are equipped with

Double Data Rate (DDR) interfaces. Each address location is

associated with two 18-bit words (CY7C1292DV18) or 36-bit

words (CY7C1294DV18) that burst sequentially into or out of

the device. Since data can be transferred into and out of the

device on every rising edge of both input clocks (K and K and

C and C), memory bandwidth is maximized while simplifying

system design by eliminating bus “turn-arounds.”

— Supports concurrent transactions

• 250-MHz clock for high bandwidth

• 2-Word Burst on all accesses

• Double Data Rate (DDR) interfaces on both Read and

Write ports (data transferred at 500 MHz) @ 250 MHz

• Two input clocks (K and K) for precise DDR timing

— SRAM uses rising edges only

• Two input clocks for output data (C and C) to minimize

clock-skew and flight-time mismatches

• Echo clocks (CQ and CQ) simplify data capture in

high-speed systems

• Single multiplexed address input bus latches address

inputs for both Read and Write ports

• Separate Port Selects for depth expansion

• Synchronous internally self-timed writes

• Available in x 18 and x 36 configurations

• Full data coherency, providing most current data

Depth expansion is accomplished with Port Selects for each

port. Port selects allow each port to operate independently.

• Core V_DD= 1.8V (±0.1V); I/O V_DDQ= 1.4V to V_DD

• Available in 165-ball FBGA package (13 x 15 x 1.4 mm)

• Offered in both lead-free and non-lead free packages

All synchronous inputs pass through input registers controlled

by the K or K input clocks. All data outputs pass through output

registers controlled by the C or C (or K or K in a single clock

domain) input clocks. Writes are conducted with on-chip

synchronous self-timed write circuitry.

• Variable drive HSTL output buffers

• JTAG 1149.1 compatible test access port

• Delay Lock Loop (DLL) for accurate data placement
