CY7C1514V18-250BZI

Memory IC Overview

The CY7C1514V18-250BZI is a 72-Mbit QDR-II SRAM organized as 2M x 36. It operates at a maximum clock frequency of 250 MHz with a core voltage of 1.8V and IO voltage ranging from 1.4V to VDD. The device utilizes a 165-Ball FBGA package measuring 15 x 17 x 1.4 mm.

Memory IC Feature Summary

• Features separate independent read and write data ports for concurrent transactions
• Supports double data rate interfaces on both read and write ports
• Includes echo clocks to simplify data capture in high-speed systems
• Provides variable drive HSTL output buffers

Memory IC Applications

• High-bandwidth networking equipment
• Telecommunications infrastructure
• Data routing applications

Memory IC Procurement Notes

Verify the specific suffix BZI against official documentation to confirm lead-free status and packaging details. Confirm RoHS compliance requirements prior to procurement, as non-compliant variants exist within this product family.

Memory IC Selection Notes

Select this component when a 2M x 36 organization is required. Ensure system design accommodates the 1.8V core supply and 1.4V to VDD IO supply range. Verify that the 165-ball FBGA footprint matches the PCB layout constraints.

Memory IC Part Context

This part belongs to the Cypress CY7C151xV18 series of synchronous pipelined SRAMs. It shares architectural similarities with the CY7C1510V18, CY7C1525V18, and CY7C1512V18, differing primarily in memory organization and address pin count.

Memory IC FAQ

How does the QDR-II architecture handle data contention?

It uses separate read and write ports to completely eliminate the need for data bus turnaround, thereby avoiding data contention.

What is the function of the ZQ pin?

The ZQ pin is used to tune the device outputs to the system data bus impedance by connecting an external resistor to ground or VDDQ.
