7133LA25PFI8

Overview

The Renesas Electronics Corporation 7133LA25PFI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2K x 16 bits. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 64-TQFP package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration without clock synchronization
• CMOS technology ensuring low power consumption during standby and active modes

Applications

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

Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm pinout compatibility and RoHS status. Confirm lead times and moisture sensitivity levels prior to ordering. Ensure design-in reviews address the 64-TQFP thermal requirements and verify that the 4.5V to 5.5V supply range aligns with target system power rails.

Selection Notes

Select this component when dual-port functionality is required for 16-bit wide data paths. Compare against the 7133LA20 variant if faster 20 ns access is needed, or the 7133SA series for alternative packaging options. Ensure the 64-TQFP footprint fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the Renesas 7133LA family of high-performance dual-port SRAMs. These devices are designed for applications requiring fast, non-blocking data exchange between two masters. The LA series typically denotes extended industrial temperature ranges compared to commercial variants.
