70V05L35PFI

Memory IC Overview

The Renesas Electronics Corporation 70V05L35PFI is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The component features a parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The device is designed for applications requiring simultaneous independent access from two ports.

Memory IC Feature Summary

• Supports true dual-port architecture allowing simultaneous read and write operations from either port without conflict.
• Features fully asynchronous operation from both ports, eliminating the need for clock synchronization between systems.
• Includes on-chip hardware support for semaphore signaling and interrupt flags to facilitate data exchange between ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging and temporary storage in industrial control units

Memory IC Procurement Notes

Verify the specific suffix 'I' against official Renesas documentation to confirm if it denotes an extended industrial temperature range or specific packaging variant, as standard listings often reference the 'PF' suffix. Confirm RoHS compliance status and end-of-life notifications directly with the manufacturer or authorized distributors before procurement planning.

Memory IC Selection Notes

Select this component when a system requires independent, simultaneous access to shared memory resources without external arbitration logic. Ensure the design accommodates the 3.3V power supply requirements and the physical dimensions of the 64-TQFP package. Verify that the 35 ns access speed meets the timing constraints of the connected processors.
