7005S35PFG8

Overview

The Renesas Electronics Corporation 7005S35PFG8 is a static random access memory component with a storage capacity of 64 kbit, organized as 8 k x 8. It features an asynchronous parallel interface and a maximum access time of 35 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power current of 250 mA. It supports single data rate (SDR) storage type and functions in temperatures from 0°C to +70°C. The component is housed in a TQFP-64 surface-mount package and supplied in reel packaging.

Feature Summary

• Dual-port architecture enabling simultaneous independent access by two masters
• Integrated hardware semaphore mechanism for bus arbitration between ports
• Asynchronous operation without reliance on external clock signals

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications requiring dual-master access

Procurement Notes

Verify the specific suffix PFG8 to confirm the TQFP-64 package and reel packaging configuration. Ensure compatibility with 5V logic levels and check RoHS status requirements against project specifications. Confirm that the 35 ns access time meets system timing constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual-port SRAM with 8-bit width and 35 ns speed is required. The TQFP-64 package suits surface-mount assembly processes. Consider the 5V operating voltage and industrial temperature range suitability for the target environment compared to lower voltage or wider temperature alternatives.

Part Context

This part belongs to the Renesas 7005S series of dual-port RAMs. It shares architectural similarities with other variants like the 7005S25 but offers a 35 ns access time. The series provides hardware-based arbitration, distinguishing it from standard single-port memories used in general-purpose computing tasks.

Replacement Considerations

Public documentation identifies the 7005L15PFG8 as an upgrade replacement for this discontinued component.
