CY7C1471BV33-133BZXC

Memory IC Overview

The CY7C1471BV33-133BZXC is a 72-Mbit (2M x 36) synchronous static random-access memory (SRAM) manufactured by Cypress Semiconductor Corp. It operates at a maximum clock frequency of 133 MHz with a typical access time of 6.5 ns. The device utilizes a 3.3V power supply, with operating voltage ranging from 3.135V to 3.6V. It is housed in a 165-LBGA package and supports surface mount installation. The component functions as volatile memory within the NoBL™ series.

Memory IC Feature Summary

• Supports parallel interface operations
• Provides flow-through SRAM functionality

Memory IC Applications

• High-performance computing systems
• Network infrastructure equipment
• Industrial control applications

Memory IC Procurement Notes

Verify the manufacturer designation carefully, as Infineon Technologies also lists this part number due to corporate acquisitions. Confirm the specific suffix BZXC matches the required package and temperature grade. Ensure compatibility with 3.3V logic levels and check for moisture sensitivity handling requirements during storage and assembly processes.

Memory IC Selection Notes

Select this component when a 72-Mbit capacity with 36-bit word width is required. The 133 MHz speed class suits applications needing low latency. Compare against other NoBL series variants if different voltage or timing specifications are needed. Ensure the 165-LBGA footprint fits the target PCB design constraints.

Memory IC Part Context

This part belongs to the CY7C1471BV33 series of synchronous SRAMs. It shares architectural similarities with other members like the CY7C1470 and CY7C1471BV25, differing primarily in supply voltage and speed grades. The NoBL technology distinguishes it from traditional asynchronous or standard synchronous memories by reducing output capacitance effects.

Memory IC Replacement Considerations

Direct substitutes include CY7C1471BV33-133BZI and CY7C1471BV33-133AXC. Verify pinout and electrical characteristics match before substitution. Other speed grades in the same package may require timing adjustments.
