70V05S55PF8

Memory IC Overview

The 70V05S55PF8 is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device operates with an access time and write cycle time of 55 nanoseconds. It supports parallel interface communication and requires a supply voltage between 3 volts and 3.6 volts. The component is housed in a 64-pin Thin Quad Flat Package measuring 14x14 millimeters. It functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two distinct ports without external arbitration logic.

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications requiring concurrent port access

Memory IC Procurement Notes

Verify the specific suffix PF8 to confirm the 64-TQFP package configuration and lead-free status. Confirm RoHS compliance requirements against the manufacturer's current documentation, as this part may be subject to discontinuation notices. Ensure the design accommodates the specified 3V to 3.6V operating voltage range for reliable asynchronous operation.

Memory IC Selection Notes

Select this component when a 64Kb dual-port SRAM with 55ns speed is required in a compact surface-mount package. It is suitable for designs needing independent port access without complex external control logic. Consider the 3.3V power supply requirement and commercial temperature limits during system architecture planning.

Memory IC Part Context

This part belongs to the 70V05S family of dual-port SRAMs from Renesas. These devices are designed for applications requiring high-speed data exchange between two processors or systems. The 70V05S series offers various speed grades and packaging options to fit different board space and performance constraints.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the 70V05S series that match the 55ns access time and 64-TQFP package. Verify if newer revisions of the same part number are available due to potential manufacturing updates or end-of-life notifications.
