CY7C1565KV18-400BZXI

Memory IC Overview

The CY7C1565KV18-400BZXI is a 72-Mbit QDR II+ synchronous SRAM with a 2M x 36 organization. It supports a maximum clock frequency of 400 MHz and operates within a core voltage range of 1.7 V to 1.9 V. The device features separate independent read and write data ports, enabling concurrent transactions without bus turnaround. It utilizes a four-word burst architecture with 2.5-cycle read latency when the DOFF pin is asserted HIGH. The component is housed in a 165-ball fine pitch ball grid array (FBGA) package measuring 13 × 15 × 1.4 mm.

Memory IC Feature Summary

• Supports concurrent read and write operations through separate independent data ports
• Features a four-word burst architecture for reduced address bus frequency
• Includes echo clocks (CQ and CQ) to simplify data capture in high-speed systems
• Provides programmable output impedance via the ZQ pin for system bus matching

Memory IC Applications

• High-bandwidth networking equipment requiring low-latency memory access
• Telecommunications infrastructure utilizing QDR interface protocols
• Industrial control systems needing full data coherency and concurrent port access

Memory IC Procurement Notes

Verify that the ordering suffix BZXI corresponds to the specific lead-free packaging and industrial temperature grade requirements for your application. Confirm compatibility with the 1.8 V core and variable I/O supply ranges specified in the datasheet. Ensure that the procurement source provides authentic Infineon or Cypress Semiconductor components to guarantee electrical characteristics and reliability standards are met.

Memory IC Selection Notes

Select this component when a 72-Mbit capacity with a 36-bit data width is required for high-throughput applications. The 400 MHz speed grade offers a balance between performance and power consumption compared to higher-frequency variants. Consider the 165-ball FBGA package constraints for PCB layout and thermal management during the design phase.

Memory IC Part Context

This part belongs to the CY7C1565KV18 family of QDR II+ SRAMs. It shares architectural similarities with other members like the CY7C1565KV18-400BZI but differs in specific ordering suffixes that may indicate variations in packaging or compliance certifications. The family is designed for applications demanding high bandwidth and simultaneous read/write capabilities.

Memory IC Replacement Considerations

The CY7C1565KV18-400BZI is a confirmed substitute within the same family offering identical electrical specifications and pinout compatibility.
