CY7C1565V18

72-Mbit QDR™-II+ SRAM 4-Word Burst

Architecture (2.5 Cycle Read Latency)

Features

Configurations

■ Separate independent read and write data ports

❐ Supports concurrent transactions

With Read Cycle Latency of 2.5 cycles:

CY7C1561V18 – 8M x 8

CY7C1576V18 – 8M x 9

CY7C1563V18 – 4M x 18

CY7C1565V18 – 2M x 36

■ 300 MHz to 400 MHz clock for high bandwidth

■ 4-Word Burst for reducing address bus frequency

■ Double Data Rate (DDR) interfaces on both Read and Write

Ports (data transferred at 800 MHz) at 400 MHz

Functional Description

The CY7C1561V18, CY7C1576V18, CY7C1563V18, and

CY7C1565V18 are 1.8V Synchronous Pipelined SRAMs,

equipped with QDR-II+ architecture. Similar to QDR-II archi-

tecture, QDR-II+ SRAMs 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 operations. QDR-II+ archi-

tecture has separate data inputs and data outputs to completely

eliminate the need to “turn-around” the data bus required with

common IO devices. Access to each port is accomplished

through a common address bus. Addresses for read and write

addresses are latched on alternate rising edges of the input (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 four 8-bit words (CY7C1561V18), 9-bit words

(CY7C1576V18), 18-bit words (CY7C1563V18), or 36-bit words

(CY7C1565V18) 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), memory bandwidth is

maximized while simplifying system design by eliminating bus

“turn-arounds”.

■ Read latency of 2.5 clock cycles

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

❐ SRAM uses rising edges only

■ Echo clocks (CQ and CQ) simplify data capture in high speed

systems

■ Data valid pin (QVLD) to indicate valid data on the output

■ 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 x8, x9, x18, and x36 configurations

■ Full data coherency providing most current data

[1]

■ Core V_DD= 1.8V ± 0.1V; IO V_DDQ= 1.4V to V_DD

■ HSTL inputs and Variable drive HSTL output buffers

■ Available in 165-ball FBGA package (15 x 17 x 1.4 mm)

■ Offered in both Pb-free and non Pb-free packages

■ JTAG 1149.1 compatible test access port

Depth expansion is accomplished with port selects for each port.

Port selects allow each port to operate independently.

■ Delay Lock Loop (DLL) for accurate data placement

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 K or K input clocks. Writes are

conducted with on-chip synchronous self-timed write circuitry.
