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)

■ 300 MHz to 400 MHz clock for high bandwidth

■ 2-word burst for reducing address bus frequency

The CY7C1566V18, CY7C1577V18, CY7C1568V18, and

CY7C1570V18 are 1.8V Synchronous Pipelined SRAM

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 both 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.

■ Double Data Rate (DDR) interfaces

(data transferred at 800 MHz) at 400 MHz

■ Read latency of 2.5 clock cycles

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

❐ SRAM uses rising edges only

Asynchronous inputs include output impedance matching input

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

systems

(ZQ). Synchronous data outputs (Q, that share the same

physical pins with the data inputs, D) are tightly matched to the

two output echo clocks CQ/CQ, eliminating the need to capture

data separately from individual DDR SRAMs 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
