CY7C038V-20AXI

Memory IC Overview

The CY7C038V-20AXI is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 576Kb, organized as 32K words by 18 bits. The device operates with an access time and write cycle time of 20 ns. It supports a supply voltage range of 3V to 3.6V and functions within an industrial temperature range of -40°C to 85°C. The component utilizes a parallel interface and is housed in a 100-TQFP package measuring 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Industrial-grade temperature rating suitable for demanding environmental conditions

Memory IC Applications

• High-speed data buffering between asynchronous system components
• FIFO buffer implementations in communication interfaces
• Cache memory applications requiring concurrent read/write operations

Memory IC Procurement Notes

Verify the specific suffix 'V' against official Cypress documentation to confirm it denotes standard commercial/industrial grade performance rather than extended variants. Confirm that the 'AXI' suffix corresponds to the lead-free and RoHS-compliant packaging configuration. Ensure the 100-TQFP footprint matches the target PCB design constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when concurrent independent access to SRAM data is required without bus contention. The 18-bit word width accommodates error correction code implementations or wide data paths. Verify that the 20 ns speed meets the system's maximum throughput requirements and that the 3V to 3.6V supply aligns with the platform's power rails.

Memory IC Part Context

This part belongs to the CY7C03x family of dual-port SRAMs, which also includes the CY7C037. While sharing similar architectural features, the CY7C038 offers a larger 576Kb capacity compared to the smaller variants in the series. It serves as a high-performance memory solution for embedded systems needing reliable, fast, and simultaneous data access capabilities.

Memory IC Replacement Considerations

Check for CY7C038AV-20AXI if an extended temperature range or updated manufacturing revision is required. Verify compatibility with CY7C037V-20AXI only if reduced capacity is acceptable.
