70V05S25PF8

Memory IC Overview

The 70V05S25PF8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 25 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 millimeters. It supports surface mount installation and functions across a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports independent simultaneous read and write operations at both Port A and Port B without bus contention.
• Utilizes high-speed CMOS technology to ensure low power consumption during active and standby modes.
• Features dedicated chip select inputs for each port to enable flexible system integration and power management.

Memory IC Applications

• High-performance digital signal processing systems requiring concurrent data access
• Network communication equipment utilizing packet buffering and switching
• Industrial control systems needing reliable volatile data storage

Memory IC Procurement Notes

Verify the specific suffix PF8 to confirm the 64-TQFP package and tape-and-reel carrier type. Confirm RoHS compliance status, as this specific part number may not meet current environmental directives. Check for obsolescence notices or end-of-life declarations from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 64-kilobit dual-port SRAM with 25-nanosecond speed is required. Ensure the design accommodates the 3.0V to 3.6V operating voltage range. Verify that the 64-pin TQFP footprint matches the printed circuit board layout constraints.

Memory IC Part Context

This part belongs to the 70V05S series of asynchronous dual-port SRAMs. It shares architectural similarities with other members like the 70V05L15PFG but differs in speed grade and voltage specifications. The series is designed for applications demanding independent port access and moderate data throughput.
