S3R6416R1M-XI70T

Memory IC Overview

The Netsol S3R6416R1M-XI70T is a 64Mb Parallel Peripheral Interface (PPI) MRAM utilizing Spin-Transfer-Torque technology. It operates on a single 1.8V supply (1.71V to 1.98V) and features an x16 I/O organization within a 48FBGA package. The device supports asynchronous page mode, providing a 70ns interpage read cycle time and a 15ns intrapage read cycle time. It offers unlimited read endurance and 10^14 write cycles with data retention of 10 years at 85°C. Designed for industrial applications, it functions reliably across a temperature range of -40°C to 85°C.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required voltage and package configuration. Confirm the component meets the intended industrial temperature requirements. Ensure the design accounts for the recommended pull-up resistor on the chip select pin during power transitions. Review the datasheet for absolute maximum ratings to prevent damage during soldering or operation.

Memory IC Selection Notes

Select this model when a non-volatile memory solution requires high endurance and fast random access speeds. The 1.8V operating voltage makes it suitable for low-power embedded systems. Consider the 48FBGA package dimensions for PCB layout constraints. Evaluate the page mode capabilities if sequential data access patterns are common in the application.

Memory IC Part Context

This component belongs to the S3R6416x1M series of 64Mb PPI MRAMs from Netsol. It is designed as a drop-in replacement for traditional FRAM, low-power SRAM, or nvSRAM devices. The series includes variants for different voltage levels and interfaces, offering flexibility for various industrial and automotive-grade memory applications.

Memory IC Replacement Considerations

Check pin compatibility with existing SRAM or FRAM footprints. Verify that the system's power supply can support the 1.8V requirement. Ensure the control logic aligns with the asynchronous page mode timing specifications.

Memory IC FAQ

Does the S3R6416R1M-XI70T require an external battery for data retention?

No, the device uses non-volatile STT-MRAM technology, which retains data without power and does not require a backup battery.

What is the page size for the x16 I/O mode?

In x16 I/O mode, the page size is 8 words, which corresponds to 16 bytes.

How does the device handle power loss?

Data is preserved automatically due to its non-volatile nature. However, the datasheet recommends using a pull-up resistor on the CS pin to prevent abnormal write operations during power-up or power-down sequences.
