CY7C1516JV18, CY7C1527JV18

CY7C1518JV18, CY7C1520JV18

72-Mbit DDR-II SRAM 2-Word

Burst Architecture

Features

Functional Description

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

■ 300 MHz clock for high bandwidth

The CY7C1516JV18, CY7C1527JV18, CY7C1518JV18, and

CY7C1520JV18 are 1.8V Synchronous Pipelined SRAM

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

SRAM core with advanced synchronous peripheral circuitry and

a 1-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 two 8-bit words in the case of CY7C1516JV18

and two 9-bit words in the case of CY7C1527JV18 that burst

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

starts with a “0” internally in the case of CY7C1516JV18 and

CY7C1527JV18. On CY7C1518JV18 and CY7C1520JV18, the

burst counter takes in the least significant bit of the external

address and bursts two 18-bit words in the case of

CY7C1518JV18 and two 36-bit words in the case of

CY7C1520JV18 sequentially into or out of the device.

■ 2-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 Delay Lock

Loop (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 for separately

capturing data from each individual DDR SRAM in the system

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

clocking and data synchronization flexibility.

■ Operates like 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 (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
