7164S35DB

Overview

The Renesas Electronics Corporation 7164S35DB is a static random access memory (SRAM) device belonging to the 7164S35 series. It features a storage capacity of 64K bits, organized as 8K by 8 bits. The component utilizes BICMOS technology and operates with a parallel interface. It supports a supply voltage range of 4.5V to 5.5V and functions within an ambient temperature range of 0°C to 70°C. The device is housed in a CDIP-28 package.

Feature Summary

• Utilizes BICMOS technology for high-speed asynchronous operation without requiring clocks or refresh cycles.
• Provides low-power standby mode to reduce system-level power consumption and cooling requirements.
• Features battery backup capability allowing data retention during power loss.

Applications

• High-speed address and chip select applications
• Battery-backed memory systems
• TTL-compatible input and output circuits

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as indicated specifications may vary. Validate package integrity for CDIP-28 housing before installation. Review discontinuation notifications for long-term supply chain implications.

Selection Notes

Select this component for designs requiring fast asynchronous SRAM with TTL compatibility. Ensure voltage levels match the 4.5V to 5.5V operating range. Consider thermal management for industrial environments if temperatures approach upper limits. Verify pinout compatibility with existing PCB layouts using the CDIP-28 footprint.
