CY7C1566V18, CY7C1577V18

CY7C1568V18, CY7C1570V18

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

Architecture (2.5 Cycle Read Latency)

Features

Functional Description

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

■ 400 MHz clock for high bandwidth

The CY7C1566V18, CY7C1577V18, CY7C1568V18, and

CY7C1570V18 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 (CY7C1566V18), 9-bit words (CY7C1577V18), 18-bit

words (CY7C1568V18), or 36-bit words (CY7C1570V18) that

burst sequentially into or out of the device.

■ 2-word burst for reducing address bus frequency

■ Double Data Rate (DDR) interfaces

(data transferred at 800 MHz) at 400 MHz

■ Available in 2.5 clock cycle latency

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

❐ SRAM uses rising edges only

Asynchronous inputs include an output impedance matching

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

systems

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.

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

■ Synchronous internally self-timed writes

[1]

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

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.

■ 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

■ Delay Lock Loop (DLL) for accurate data placement

Configurations

With Read Cycle Latency of 2.5 cycles:

CY7C1566V18 – 8M x 8

CY7C1577V18 – 8M x 9

CY7C1568V18 – 4M x 18

CY7C1570V18 – 2M x 36
