70V05S12PFI8

Memory IC Overview

The 70V05S12PFI8 is a dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 64 Kbit, organized as 8K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 12 ns. It operates within a supply voltage range of 3 V to 3.6 V and supports surface-mount installation in a 64-TQFP package measuring 14x14 mm. The component is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent access to two ports for concurrent read/write operations
• Asynchronous operation eliminates the need for external clock synchronization
• Parallel interface architecture enables direct connection to standard microprocessors

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates potential variations across manufacturing lots or specific suffixes. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure the supplier provides valid traceability documents matching the Renesas manufacturer part number. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Memory IC Selection Notes

Select this component when asynchronous dual-port functionality is required for 8-bit wide data paths. The 12 ns speed class suits moderate-frequency bus architectures. Compare against synchronous alternatives if deterministic timing is critical. Verify that the 64-TQFP footprint fits the available PCB real estate constraints.

Memory IC Part Context

This part belongs to the 70V05 series of dual-port SRAMs. It shares architectural similarities with the 70V05L15PFG8 but offers faster access speeds. The 'S' suffix typically denotes specific performance or packaging variants within the family. It serves as a legacy component often replaced by newer high-density equivalents in modern designs.
