CY7C188-25VC

Memory IC Overview

The CY7C188-25VC is a standard asynchronous Static Random Access Memory (SRAM) integrated circuit manufactured by Cypress Semiconductor Corp. It provides a total storage capacity of 288Kbits, organized as 32K words by 9 bits. The device features a parallel interface with a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 1.7V to 1.9V and is housed in a 32-lead 300-mil molded Small Outline J-Lead (SOJ) package.

Memory IC Feature Summary

• Asynchronous operation for flexible system integration without clock synchronization requirements
• Parallel data interface supporting standard memory bus architectures
• CMOS technology ensuring low power consumption during active and standby modes

Memory IC Applications

• Embedded systems requiring non-volatile-like persistence with SRAM speed
• Industrial control units utilizing parallel memory interfaces
• Consumer electronics devices with specific voltage and form factor constraints

Memory IC Procurement Notes

Verify the exact package variant, as the base part number may correspond to different lead forms such as SOJ or PLCC. Confirm RoHS compliance status, as older Cypress batches may be non-compliant. Check lifecycle status to ensure availability for long-term production. Validate supply chain authenticity through authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when an asynchronous parallel SRAM with 288Kbit capacity is required. Ensure the design supports the 1.7V to 1.9V operating voltage range. Consider the 32-pin SOJ footprint for PCB layout compatibility. Verify that the 25ns access time meets the system timing requirements compared to faster synchronous alternatives.

Memory IC Part Context

This part belongs to the Cypress CY7C188 family of asynchronous SRAMs. It is designed for applications needing moderate density memory with simple interface protocols. The series typically includes variants with different access speeds and package options, maintaining consistent electrical characteristics across the family.

Memory IC Replacement Considerations

Direct substitutes include other 32Kx9 asynchronous SRAMs from Cypress or Infineon with compatible pinouts and voltage levels. Verify package dimensions and electrical specifications before substitution. Cross-reference with CY7C188 variants offering different speed grades if timing margins allow.
