CY7C1317CV18, CY7C1917CV18

CY7C1319CV18, CY7C1321CV18

18-Mbit DDR-II SRAM 4-Word

Burst Architecture

Features

Functional Description

■ 18-Mbit density (2M x 8, 2M x 9, 1M x 18, 512K x 36)

■ 300 MHz clock for high bandwidth

The CY7C1317CV18, CY7C1917CV18, CY7C1319CV18, and

CY7C1321CV18 are 1.8V Synchronous Pipelined SRAMs

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

SRAM core with advanced synchronous peripheral circuitry and

a two-bit burst counter. 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 C and C if provided, or on the rising

edge of K and K if C/C are not provided. Each address location

is associated with four 8-bit words in the case of CY7C1317CV18

and four 9-bit words in the case of CY7C1917CV18 that burst

sequentially into or out of the device. The burst counter always

starts with a ‘00’ internally in the case of CY7C1317CV18 and

CY7C1917CV18. For CY7C1319CV18 and CY7C1321CV18,

the burst counter takes in the least two significant bits of the

external address and bursts four 18-bit words in the case of

CY7C1319CV18, and four 36-bit words in the case of

CY7C1321CV18, sequentially into or out of the device.

■ 4-word burst for reducing address bus frequency

■ Double Data Rate (DDR) interfaces

(data transferred at 600 MHz) at 300 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

■ Synchronous internally self-timed writes

■ DDR-II operates with 1.5 cycle read latency when the DLL is

enabled

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 to capture data

separately from each individual DDR SRAM in the system

design. Output data clocks (C/C) enable maximum system

clocking and data synchronization flexibility.

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

DLL off mode

■ 1.8V core power supply with HSTL inputs and outputs

■ Variable drive HSTL output buffers

■ Expanded HSTL output voltage (1.4V–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 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.

■ 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

■ Delay Lock Loop (DLL) for accurate data placement
