70V05L25J

Memory IC Overview

The 70V05L25J is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The device supports parallel interface operations with a maximum access time of 25 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum power consumption of 190 mA. The component is housed in a 68-PLCC package and is designed for surface-mount installation. It functions reliably across an operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring a system clock signal
• Parallel data bus interface for standard digital connectivity

Memory IC Applications

• Data buffering in high-speed communication systems
• Cache memory implementation in embedded processors
• Temporary storage in industrial control logic

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance. Confirm moisture sensitivity level requirements before handling. Check for specific discontinuation notices or production change notifications that may affect long-term availability. Ensure the supplier provides valid traceability documents for this legacy component.

Memory IC Selection Notes

Select this part when dual-port functionality is required for 8-bit wide data paths. Compare against single-port alternatives if simultaneous access is unnecessary. Verify that the 68-pin PLCC package fits the target PCB layout constraints. Ensure the 3V to 3.6V voltage range matches the system power rails.

Memory IC Part Context

This component belongs to the 70V05 series of asynchronous SRAMs. It shares architectural similarities with other parts in the family but differs in pin count and organization. The 70V05 series is widely used in applications requiring fast, independent read/write cycles on two separate ports.

Memory IC Replacement Considerations

Direct substitutes include IDT70V05S25J8 and IDT70V05L25J8. These parts offer equivalent electrical specifications and pin compatibility. Verify package variations and suffix codes to ensure mechanical fit.
