CY7C1545V18-333BZC

Memory IC Overview

The CY7C1545V18-333BZC is a 72-Mbit QDR-II+ synchronous SRAM with a 2M x 36 organization. It supports a maximum clock frequency of 333 MHz and features a four-word burst architecture with 2.0 cycle read latency. The device utilizes separate independent read and write data ports to support concurrent transactions, eliminating bus turn-arounds. It operates on a single multiplexed address input bus latched for both ports. Power supplies include a core VDD of 1.8V ± 0.1V and IO VDDQ ranging from 1.4V to VDD.

Memory IC Feature Summary

• Separate independent read and write data ports enable concurrent transactions without bus contention
• Four-word burst architecture reduces address bus frequency requirements
• Double Data Rate interfaces on both read and write ports maximize bandwidth
• Echo clocks simplify data capture in high-speed systems

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific speed grade suffix (e.g., -333) against the required system clock frequency. Confirm package type matches the 165-Ball FBGA footprint dimensions. Ensure voltage levels align with the specified core and I/O supply ranges before integration.

Memory IC Selection Notes

Select this component for designs requiring high throughput with independent read/write paths. Consider the 333 MHz speed bin if system timing allows. Verify compatibility with HSTL input/output buffer standards and impedance matching requirements via the ZQ pin.

Memory IC Part Context

This part belongs to the Cypress/Infineon QDR-II+ SRAM family, designed for high-performance memory applications. It shares architectural similarities with QDR-II but offers enhanced features like echo clocks and valid data indicators. The 72-Mbit density provides substantial storage for complex buffering tasks.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the same QDR-II+ family. Verify that any substitute maintains the 2.0 cycle latency and 333 MHz operational frequency. Ensure the replacement supports the same 165-ball FBGA package.
