CY7C2644KV18-333BZXI is 1.8 V synchronous pipelined SRAMs, equipped with QDR II+architecture.

Features Of CY7C2644KV18-333BZXI

Separate independent read and write data ports

Supports concurrent transactions

250 MHz clock for high bandwidth

Two-word burst for reducing address bus frequency

Double data rate (DDR) interfaces on both read and write ports (data transferred at 500 MHz) at 250 MHz

Available in 2.0 clock cycle latency

Two input clocks for precise DDR timing

SRAM uses rising edges only

Echo clocks simplify data capture in high-speed systems

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

On-die termination (ODT) feature

Single multiplexed address input bus latches address inputs for both read and write ports

Separate port selects for depth expansion

Quad data rate 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

Core VDD = 1.8 V± 0.1 V; I/O VDDQ = 1.4 V to VDD

Supports both 1.5 V and 1.8 V I/O supply

High-speed transceiver logic (HSTL) inputs and variable drive HSTL output buffers

Available in 165-ball CCGA (21 × 25 × 2.83 mm)

JTAG 1149.1 compatible test access port

Phase Locked Loop (PLL) for accurate data placement

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
