7005L12PFI8

Overview

The Renesas Electronics Corporation 7005L12PFI8 is an asynchronous dual-port static random access memory (SRAM) device. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The component supports parallel interface communication with a maximum access time of 12 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 280 mA. The device is designed for surface mount installation in a TQFP-64 package. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access by two masters
• Supports asynchronous operation for flexible system integration
• Utilizes standard parallel interface for straightforward connectivity

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the exact suffix PFI8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records may vary. Check for obsolescence notices or last-time buy dates before finalizing procurement plans due to potential discontinuation risks associated with legacy SRAM lines.

Selection Notes

Select this component when dual-master access is required without external arbitration logic. Ensure the design accommodates the 5V logic levels and 280 mA current draw. Verify that the TQFP-64 footprint matches the PCB layout constraints. Consider thermal management requirements given the power dissipation characteristics at maximum operating temperatures.
