70V05S20J

Memory IC Overview

The Renesas Electronics Corporation 70V05S20J 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 features an asynchronous parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package. The component is designed for commercial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations on separate ports.

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications requiring concurrent data handling

Memory IC Procurement Notes

Verify the specific suffix J against official manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as legacy components may vary. Check current lifecycle status, as this part may be discontinued or subject to last-time buy restrictions. Validate moisture sensitivity levels before reflow soldering processes.

Memory IC Selection Notes

Select this component when a design requires independent dual-port access to shared memory without external arbitration logic. Ensure the system power supply strictly adheres to the 3.0V to 3.6V operating range. Verify that the 68-PLCC footprint matches the printed circuit board layout constraints. Consider thermal dissipation requirements within the specified commercial temperature limits.

Memory IC Part Context

This device belongs to the IDT 70V05 series of dual-port SRAMs, originally developed by Integrated Device Technology and later acquired by Renesas Electronics. The series is characterized by low-power CMOS technology and asynchronous operation. These components are widely used in telecommunications and industrial automation where reliable, fast, and independent memory access is critical for system performance.

Memory IC Replacement Considerations

Officially documented substitutes include the 70V05L15JG. Verify electrical specifications and pin compatibility before substitution.
