70V05L20J8

Memory IC Overview

The Renesas Electronics Corporation 70V05L20J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device operates asynchronously with parallel interfaces for both read and write operations. Key electrical parameters include an access time of 20 nanoseconds and a supply voltage range of 3 volts to 3.6 volts. Maximum power consumption is specified at 190 milliamperes. The component supports single data rate transfers and functions within an ambient temperature range of 0°C to 70°C. It is housed in a 68-lead Plastic Leadless Chip Carrier package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access via separate clocks and control signals
• Asynchronous operation allowing flexible integration into systems without strict clock synchronization
• Single data rate transfer mechanism for standard parallel data input and output

Memory IC Applications

• High-speed buffering in telecommunications equipment
• Data caching in industrial automation controllers
• Temporary storage in embedded network processing units

Memory IC Procurement Notes

Verify the specific suffix J8 against official manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as historical records indicate non-compliance for this variant. Check for End-of-Life notices or obsolescence declarations from Renesas before finalizing procurement plans. Ensure voltage levels match the 3V to 3.6V specification to prevent device damage.

Memory IC Selection Notes

Select this component when a system requires independent read and write ports for concurrent data handling. The 20ns access time suits moderate-speed asynchronous applications. Verify that the 68-pin PLCC footprint fits the target PCB layout. Consider the 3.3V operating voltage requirement for power supply design. Evaluate thermal dissipation capabilities given the maximum current draw specifications.

Memory IC Part Context

This part belongs to the Renesas 70V05 series of dual-port SRAMs. The series offers various access speeds and package options to support different performance requirements. The 70V05L20J8 specifically targets applications needing reliable, fast, asynchronous memory with dual-port capabilities in a standard surface-mount package.

Memory IC Replacement Considerations

Officially documented substitutes include the 70V05L15JG. Verify functional equivalence and pin compatibility before substitution.
