7130SA55PFI

Memory IC Overview

The Renesas Electronics Corporation 7130SA55PFI is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kbit, organized as 1K x 8 bits. The device features parallel interface access with a maximum access time of 55 ns. It operates on a single power supply voltage ranging from 4.5 V to 5.5 V. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It supports surface-mount installation and functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access by two processors
• Asynchronous operation allowing flexible timing control for both ports
• CMOS technology ensuring low power consumption during active and standby modes

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Communication protocol conversion interfaces requiring temporary storage
• Embedded systems needing independent processor access to shared memory

Memory IC Procurement Notes

Verify the specific package variant, as the PFI suffix denotes a 64-TQFP form factor. Confirm RoHS compliance status, as older manufacturing runs may not meet current environmental directives. Check for end-of-life notifications or discontinuance notices from Renesas, as this part number may be obsolete. Ensure the supplier provides valid traceability documentation for critical applications.

Memory IC Selection Notes

Select this component when dual-port functionality is required for 8K-bit memory configurations. Compare against the 7132 series if 16K-bit capacity is needed instead. Consider the 71V30 series for 3.3V logic compatibility if lower voltage operation is necessary. Verify that the 55 ns access speed meets the system timing requirements for both read and write cycles.

Memory IC Part Context

This device belongs to the Renesas 7130SA/LA family of high-speed dual-port SRAMs. These components are designed for applications requiring concurrent access from multiple masters without external arbitration hardware. The 7130SA variant specifically targets commercial temperature ranges and standard voltage levels, distinguishing it from industrial grade or low-voltage alternatives within the broader product line.

Memory IC Replacement Considerations

The 7130LA25PFGI is listed as an upgrade alternative offering faster performance. Verify pinout compatibility and electrical specifications before substitution. Other family members like the 7130SA55J8 offer different packaging options such as PLCC.
