7130SA35J

Memory IC Overview

The Renesas Electronics Corporation 7130SA35JI is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a junction temperature range from -40°C to +85°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports without bus contention or wait states.
• Utilizes CMOS technology to provide high-speed asynchronous data transfer capabilities.
• Features a compact surface-mount package suitable for dense printed circuit board layouts.

Memory IC Applications

• High-performance digital signal processing systems requiring low-latency data buffering.
• Telecommunications equipment utilizing fast cache memory structures.
• Industrial control systems needing reliable volatile data storage.

Memory IC Procurement Notes

Verify the exact suffix designation, as the manufacturer identifier includes 'I' (7130SA35JI), indicating specific commercial temperature grading and packaging variations. Confirm RoHS compliance status, as older production runs may not meet current environmental directives. Check for End-of-Life notifications or Product Change Notices that may affect long-term availability and assembly site consistency before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a system requires true simultaneous bidirectional data access through separate address and data buses. Ensure the design accommodates the 5.0V nominal supply voltage requirements and the physical dimensions of the 52-PLCC footprint. Consider thermal management strategies if operating near the upper temperature limits, as performance specifications are guaranteed only within the defined industrial temperature range.

Memory IC Part Context

This part belongs to the IDT 7130SA family of dual-port SRAMs, originally developed by Integrated Device Technology and later acquired by Renesas Electronics. These devices were engineered to replace single-port memories in applications demanding higher throughput. The 7130SA series established a standard for small-footprint, high-speed memory solutions in embedded computing architectures during its active production lifecycle.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with potential cross-brand alternatives by matching the 1Kx8 organization, 35ns speed grade, and 52-PLCC package dimensions.
