7005S35JG8

Overview

The Renesas Electronics Corporation 7005S35JG8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 64 kbit. It features an 8K x 8 organization and supports parallel interface communication. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 250 mA. It offers a typical access time of 35 ns and functions reliably across an operating temperature range from 0°C to +70°C. The component is housed in a surface-mount TQFP-64 package.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two distinct ports without conflict.
• Integrated on-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between master and slave configurations.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption during inactive periods.

Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Master/slave dual-port RAM configurations in 16-bit or wider word systems for efficient data transfer.
• Industrial control systems operating within standard commercial temperature ranges.

Procurement Notes

Verify the specific suffix JG8 against official Renesas documentation to confirm the TQFP-64 package type and lead-free status. Confirm RoHS compliance details as historical data may vary. Check current lifecycle status, as this part number may be discontinued or subject to last-time buy restrictions. Ensure moisture sensitivity level (MSL 3) handling procedures are followed during assembly.

Selection Notes

Select this component when true dual-port functionality with hardware arbitration is required for 8-bit wide data buses. Compare access times and package options against other variants in the 7005S series if higher speeds or different form factors are needed. Verify that the 5V TTL-compatible I/O levels match the system logic requirements. Consider thermal management capabilities within the specified commercial temperature range.

Part Context

The 7005S35JG8 belongs to the Renesas 7005 family of high-speed dual-port SRAMs. This family provides flexible memory solutions for applications needing concurrent access from multiple processors or controllers. The 7005 series is known for its robust arbitration logic and low-power modes, making it suitable for complex embedded systems requiring reliable shared memory resources.
