7005L25PFI8

Overview

The 7005L25PFI8 is a dual-port static random access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The device supports parallel asynchronous interfaces with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power current of 280 mA. The component is designed for surface mount installation in a TQFP-64 package, suitable for commercial temperature ranges.

Feature Summary

• Provides independent read/write access to two ports simultaneously for high-throughput data handling
• Utilizes asynchronous parallel interface architecture for flexible system integration
• Employs single data rate (SDR) storage technology for standard memory operations

Applications

• Buffering applications requiring simultaneous host and peripheral access
• Data logging systems needing fast write speeds
• Communication equipment utilizing FIFO-like buffering capabilities

Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or environmental ratings. Confirm RoHS compliance status directly with the manufacturer, as legacy parts may have varying regulatory statuses. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a 64 kbit dual-port SRAM with 25 ns access speed is required. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and the TQFP-64 footprint. Consider the 280 mA maximum current consumption for power budget calculations. Verify that the parallel interface signals match the target controller's capabilities.

Part Context

This part belongs to the Renesas 7005L series of dual-port SRAMs. The series offers various access times and packaging options to suit different performance and space constraints. The 7005L25 variant specifically targets applications requiring moderate speed with a 25 ns access time, balancing performance and power consumption for general-purpose memory tasks.

Replacement Considerations

Check for direct replacements such as IDT7005L25PFI8, which shares identical specifications. Verify compatibility with other 7005L series variants if pinouts differ. Consult Renesas for any updated components replacing the 7005L family.
