7133LA35FB

Memory IC Overview

The Renesas Electronics Corporation 7133LA35FB is a CMOS dual-port static random-access memory (SRAM) device. It provides a storage capacity of 32 kbit, organized as 2K words by 16 bits. The component features an asynchronous parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-FPACK package. The device is designed for industrial temperature ranges, functioning between -55°C and +125°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation allowing flexible timing integration without external clock synchronization
• CMOS technology providing low power consumption relative to older bipolar SRAM implementations

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify the specific suffix requirements against current manufacturer documentation, as packaging and compliance statuses may vary. Confirm end-of-life status and availability through authorized distributors. Ensure compatibility with existing PCB footprints and thermal management designs before finalizing procurement orders.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare access times and power specifications against alternative SRAM families. Verify package dimensions and pinout compatibility with the target circuit board design. Consider industrial temperature ratings for harsh environment deployments.

Memory IC Part Context

This part belongs to the Renesas 7133SA/LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7133SA35J but differs in package type and operating temperature range. The LA series typically denotes extended industrial temperature capabilities compared to commercial variants.
