PRELIMINARY

72-Mbit DDR-II+ SRAM 2-Word Burst

Architecture (2.5 Cycle Read Latency) with ODT

Features

Configurations

■ 72-Mbit density (8M x 8, 8M x 9, 4M x 18, 2M x 36)

■ 550 MHz clock for high bandwidth

With Read Cycle Latency of 2.5 cycles:

CY7C2566KV18 – 8M x 8

CY7C2577KV18 – 8M x 9

■ 2-word burst for reducing address bus frequency

CY7C2568KV18 – 4M x 18

CY7C2570KV18 – 2M x 36

■ Double Data Rate (DDR) interfaces

(data transferred at 1100 MHz) at 550 MHz

■ Available in 2.5 clock cycle latency

Functional Description

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

❐ SRAM uses rising edges only

The CY7C2566KV18, CY7C2577KV18, CY7C2568KV18, and

CY7C2570KV18 are 1.8V Synchronous Pipelined SRAMs

equipped with DDR-II+ architecture. The DDR-II+ consists of an

SRAM core with advanced synchronous peripheral circuitry.

Addresses for read and write are latched on alternate rising

edges of the input (K) clock. Write data is registered on the rising

edges of both K and K. Read data is driven on the rising edges

of K and K. Each address location is associated with two 8-bit

words (CY7C2566KV18), 9-bit words (CY7C2577KV18), 18-bit

words (CY7C2568KV18), or 36-bit words (CY7C2570KV18) that

burst sequentially into or out of the device.

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

systems

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

■ On-Die Termination (ODT) feature

❐ Supported for D_[x:0], BWS_[x:0], and K/K inputs

■ Synchronous internally self-timed writes

■ DDR-II+ operates with 2.5 cycle read latency when DOFF is

asserted HIGH

These devices have an On-Die Termination feature supported

for D_[x:0], BWS_[x:0], and K/K inputs, which helps eliminate

external termination resistors, reduce cost, reduce board area,

and simplify board routing.

■ Operates similar to DDR-I device with 1 cycle read latency

when DOFF is asserted LOW

[1]

Asynchronous inputs include an output impedance matching

input (ZQ). Synchronous data outputs (Q, sharing the same

physical pins as the data inputs D) are tightly matched to the two

output echo clocks CQ/CQ, eliminating the need for separately

capturing data from each individual DDR SRAM in the system

design.

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

❐ Supports both 1.5V and 1.8V IO supply

■ HSTL inputs and variable drive HSTL output buffers

■ Available in 165-Ball FBGA package (13 x 15 x 1.4 mm)

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

■ JTAG 1149.1 compatible test access port

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.

■ Phase Locked Loop (PLL) for accurate data placement
