70V05S15PF

Memory IC Overview

The 70V05S15PF is a 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 asynchronous parallel interface operation with a maximum access time of 15 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package. The component is designed for industrial temperature ranges spanning from 0°C to 70°C.

Memory IC Feature Summary

• Supports independent simultaneous read and write operations on both ports without bus conflicts
• Provides high-speed asynchronous data transfer with fast access times
• Operates on a single low-voltage power supply compatible with standard logic levels

Memory IC Applications

• High-performance embedded systems requiring concurrent data access
• Network communication equipment buffer memory
• Industrial control system data logging

Memory IC Procurement Notes

Verify the specific suffix requirements for package type and temperature grade before ordering. Confirm RoHS compliance status as older batches may not meet current environmental regulations. Check for obsolescence notices or end-of-life declarations from the manufacturer. Ensure compatibility with existing PCB footprints for the PLCC-68 package. Validate supply chain authenticity through authorized distributors.

Memory IC Selection Notes

Select this component when dual-port functionality is required for separate master devices accessing shared memory. Compare access speeds against other SRAM families if higher throughput is needed. Consider pin count and package dimensions relative to board space constraints. Evaluate power consumption differences between 3.3V and 5V variants if system voltage changes occur.

Memory IC Part Context

This part belongs to the 70V05 series of dual-port SRAMs from Renesas. The series offers various speed grades and packaging options to suit different design requirements. The 70V05S15PF specifically targets applications needing moderate speed with a compact leadless package format. It serves as a legacy option for designs originally specified with IDT branding under similar part numbers.

Memory IC Replacement Considerations

Direct replacements include the 70V05L15PFG in a TQFP package or the 70V05S15J8 in tape-and-reel PLCC packaging. Verify pinout compatibility and electrical specifications before substituting. Review datasheet revisions for any functional changes in newer generations.
