CY7C1266V18

CY7C1277V18

CY7C1268V18

CY7C1270V18

36-Mbit DDR-II+ SRAM 2-Word

Burst Architecture (2.5 Cycle Read Latency)

Functional Description

Features

• 36-Mbit density (4M x 8, 4M x 9, 2M x 18, 1M x 36)

• 300 MHz to 400 MHz clock for high bandwidth

• 2-Word burst for reducing address bus frequency

The CY7C1266V18, CY7C1277V18, CY7C1268V18, and

CY7C1270V18 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 both K and K. Each address location is

associated with two 8-bit words (CY7C1266V18), 9-bit words

(CY7C1277V18), 18-bit words (CY7C1268V18), or 36-bit

words (CY7C1270V18), that burst sequentially into or out of

the device.

• Double Data Rate (DDR) interfaces

(data transferred at 800 MHz) @ 400 MHz

• Read latency of 2.5 clock cycles

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

— SRAM uses rising edges only

• Echo clocks (CQ and CQ) simplify data capture in high

speed systems

Asynchronous inputs include 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.

• 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

• HSTL inputs and variable drive HSTL output buffers

• Available in 165-ball FBGA package (15 x 17 x 1.4 mm)

• Offered in both in 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.

• Delay Lock Loop (DLL) for accurate data placement

Configurations

With Read Cycle Latency of 2.5 cycles:

CY7C1266V18 – 4M x 8

CY7C1277V18 – 4M x 9

CY7C1268V18 – 2M x 18

CY7C1270V18 – 1M x 36
