7130SA35PF

Memory IC Overview

The Renesas Electronics Corporation 7130SA35PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The component features a parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The device is designed for standalone 8-bit applications or as a master unit in larger systems.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct processors
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Integrated interrupt logic to facilitate efficient interprocessor communication and status signaling

Memory IC Applications

• Interprocessor communication links in multi-core embedded systems
• High-speed data buffering between microprocessors and peripheral devices
• Master dual-port RAM configuration in 16-bit or wider word width systems

Memory IC Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check current lifecycle status, as this part may be discontinued or subject to limited availability. Ensure ECAD models match the exact physical dimensions of the TQFP-64 package for accurate PCB layout integration.

Memory IC Selection Notes

Select this component when a system requires non-blocking concurrent access to shared memory resources. The 35 ns speed suits moderate-frequency digital signal processing tasks. Verify that the 64-pin TQFP footprint aligns with existing board designs. Consider power consumption limits under the specified 4.5V to 5.5V operating range during active read/write cycles.

Memory IC Part Context

This device belongs to the Renesas 7130 series of dual-port SRAMs. It serves as an 8-bit standalone solution or pairs with 16-bit slave counterparts like the 7140 series. The technology utilizes CMOS processes to balance high-speed performance with manageable power dissipation for industrial and commercial environments.

Memory IC Replacement Considerations

Official substitutes include the 7130LA35PF for extended temperature ranges. Cross-vendor equivalents require careful verification of pin compatibility and electrical characteristics to ensure functional parity.
