7132SA35JI8

Overview

The Renesas Electronics Corporation 7132SA35JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm x 19.13mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• Real-time data buffering in industrial control systems.

Procurement Notes

Verify the specific suffix JI8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status, as earlier variants may not meet current environmental standards. Check for End-of-Life notifications or Product Change Notices that may affect long-term availability or manufacturing location. Ensure the source document matches the exact part number to avoid substitution errors.

Selection Notes

Select this component when a system requires independent concurrent access to shared memory without external arbitration logic. The 35ns speed suits moderate-frequency asynchronous interfaces. Verify that the 52-PLCC footprint fits the target PCB layout constraints. Consider the 4.5V to 5.5V supply requirement for power rail compatibility.

Part Context

This part belongs to the 7132SA family of high-performance dual-port SRAMs from Renesas Electronics. These devices are designed for applications requiring fast, independent data access from two different masters. The family typically includes variations in speed grades, organization, and package types to support diverse embedded memory needs.

Replacement Considerations

Consult official Renesas datasheets for qualified substitute part numbers. Verify electrical and mechanical compatibility before replacement.
