70V05S25J8

Memory IC Overview

The 70V05S25J8 is an asynchronous dual-port static random access memory (SRAM) manufactured by Renesas Electronics. It provides a storage capacity of 64 kbit, organized as 8K words by 8 bits. The device operates with a maximum access time of 25 ns and supports parallel interface communication. It functions within a supply voltage range of 3 V to 3.6 V, with a maximum power consumption of 190 mA. The component is housed in a 68-PLCC package suitable for surface mount technology and operates reliably between 0°C and +70°C.

Memory IC Feature Summary

• Supports independent simultaneous read/write operations at both Port A and Port B without conflict.
• Features asynchronous operation allowing flexible timing control for data transfers.
• Includes dedicated chip select inputs to enable low-power standby modes.

Memory IC Applications

• High-speed data buffering in telecommunications equipment.
• Cache memory implementation in embedded processing systems.
• Data logging applications requiring rapid write cycles.

Memory IC Procurement Notes

Verify the specific suffix J8 to confirm the lead-free status and packaging type, as variations exist within the series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as some listings indicate non-compliance. Check for moisture sensitivity level requirements during handling and storage to prevent damage before soldering.

Memory IC Selection Notes

Select this component when a dual-port architecture is required for concurrent data access from two different masters. Ensure the system voltage aligns with the 3.3 V nominal requirement. Consider the 68-pin PLCC footprint for PCB layout compatibility. Evaluate if the 25 ns speed meets the system timing constraints compared to faster alternatives.

Memory IC Part Context

This part belongs to the 70V05S25 family of dual-port SRAMs. It shares architectural similarities with other members like the 70V05L25J8 but differs in pin count and organization. The series is designed for applications needing high-speed independent port access. Note that this specific model is listed as discontinued in several distributor databases.

Memory IC Replacement Considerations

IDT70V05S25J8 is a documented alias for this component. Verify pinout and electrical specifications match exactly before substitution. Other family members may require adapter solutions due to package differences.
