7133LA15PFI

Overview

The Renesas 7133LA15PFI is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 32 kbit, organized as 2K x 16 bits. It features an asynchronous parallel interface and supports a maximum access time of 15 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 280 mA. It is housed in a 68-pin PLCC package and is designed for surface mount installation. The component supports single data rate (SDR) storage type and is rated for commercial temperature operation from 0°C to +70°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access
• Supports high-speed asynchronous parallel data transfer
• Utilizes CMOS technology for low power consumption

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial control applications needing reliable volatile memory
• Telecommunications equipment utilizing parallel SRAM interfaces

Procurement Notes

Verify the specific suffix requirements for your design, as packaging and lead frame materials may vary. Confirm RoHS compliance status for your region before ordering. Check for obsolescence notices or lifecycle changes, as this part number may be discontinued. Ensure your bill of materials accounts for moisture sensitivity levels during assembly. Validate that the 68-PLCC package fits your PCB footprint constraints.

Selection Notes

Select this component when a 15 ns access time is required for 2K x 16 bit dual-port memory. Compare against the 7133LA20 series if slower speeds are acceptable for cost reduction. Consider the 7133SA series if industrial temperature ranges (-55°C to +125°C) are necessary instead of commercial grades. Evaluate package availability, as PLCC options may differ from TQFP alternatives in the same family.

Part Context

This device belongs to the Renesas 7133LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7133LA20 and 7133LA25, differing primarily in access speed and operating temperature ratings. The LA designation typically indicates commercial temperature range and specific packaging variants compared to the SA series.

Replacement Considerations

The 7133LA20PFG8 is listed as a similar replacement option by distributors. Verify pin compatibility and electrical specifications before substitution. Other potential substitutes include parts from the IDT 7133 family due to historical lineage.
