CY7C1143KV18/CY7C1145KV18

18-Mbit QDR^®II+ SRAM Four-Word

Burst Architecture (2.0 Cycle Read Latency)

18-Mbit QDR^®II+ SRAM Four-Word Burst Architecture (2.0 Cycle Read Latency)

Features

Configurations

■ Separate independent read and write data ports

❐ Supports concurrent transactions

With Read Cycle Latency of 2.0 cycles:

CY7C1143KV18 – 1M × 18

■ 450-MHz clock for high bandwidth

CY7C1145KV18 – 512K × 36

■ Four-word burst for reducing address bus frequency

Functional Description

■ Double data rate (DDR) Interfaces on both read and write ports

(data transferred at 900 MHz) at 450 MHz

The CY7C1143KV18, and CY7C1145KV18 are 1.8

Synchronous Pipelined SRAMs, equipped with QDR II+

architecture. Similar to QDR II architecture, QDR II+ architecture

consists of two separate ports: the read port and the write port to

access the memory array. The read port has dedicated data

outputs to support read operations and the write port has

dedicated data inputs to support write operations. QDR II+

architecture has separate data inputs and data outputs to

completely eliminate the need to “turnaround” the data bus that

exists with common I/O devices. Each port is accessed through

a common address bus. Addresses for read and write addresses

are latched on alternate rising edges of the input (K) clock.

Accesses to the QDR II+ read and write ports are completely

independent of one another. To maximize data throughput, both

read and write ports are equipped with DDR interfaces. Each

address location is associated with four 18-bit words

(CY7C1143KV18), or 36-bit words (CY7C1145KV18) that burst

sequentially into or out of the device. Because data is transferred

into and out of the device on every rising edge of both input

clocks (K and K), memory bandwidth is maximized while

simplifying system design by eliminating bus ‘turnarounds’.

■ Available in 2.0 clock cycle latency

■ 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

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

■ Single multiplexed address input bus latches address inputs

for read and write ports

■ Separate port selects for depth expansion

■ Synchronous internally self-timed writes

■ QDR^®II+ operates with 2.0 cycle read latency when DOFF is

asserted HIGH

■ Operates similar to QDR I device with one cycle read latency

when DOFF is asserted LOW

■ Available in × 18, and × 36 configurations

■ Full data coherency, providing most current data

Depth expansion is accomplished with port selects, which

enables each port to operate independently.

[1]

■ Core V_DD= 1.8 V± 0.1 V; I/O V_DDQ= 1.4 V to V_DD

❐ Supports both 1.5 V and 1.8 V I/O supply

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 (13 × 15 × 1.4 mm)

■ Offered in both Pb-free and non Pb-free packages

■ JTAG 1149.1 compatible test access port

■ Phase-locked loop (PLL) for accurate data placement
