S3R1616R1M-XI70T

Memory IC Overview

The Netsol S3R1616R1M-XI70T is a 16Mb Parallel Peripheral Interface (PPI) MRAM utilizing STT-MRAM technology. It operates on a single 1.71V to 1.98V supply and supports x16 or x8 I/O modes with asynchronous page mode access. The device features a 70ns interpage read cycle time, 15ns intrapage read/write cycle time, and 240ns interpage write cycle time. It offers unlimited read endurance, 10^14 write cycles, and 10-year data retention at 85°C. Operating temperature range is -40°C to 85°C.

Memory IC Feature Summary

• Non-volatile memory architecture based on Spin-Transfer-Torque Magnetoresistive Random Access Memory (STT-MRAM).
• Supports parallel asynchronous interface with dedicated page mode functions for enhanced read and write performance.
• Provides flexible I/O configurations including x16 mode with independent lower and upper byte control signals.
• Eliminates the need for external error correction codes due to inherent data integrity capabilities.

Memory IC Applications

• Industrial code storage applications requiring high reliability.
• Real-time data logging systems in industrial environments.
• Backup memory solutions for embedded designs.
• Working memory replacements for low-power SRAM or nvSRAM.

Memory IC Procurement Notes

Verify that the specific suffix XI70T corresponds to the intended package type and density variant within the S3R16(80)xxR1M family. Confirm compatibility with existing PCB layouts by checking pin assignments against the datasheet's x16 or x8 I/O mode diagrams. Ensure power supply rails strictly adhere to the 1.71V to 1.98V operating range to maintain specified timing parameters and data retention characteristics.

Memory IC Selection Notes

Select this component when replacing volatile memories like FRAM, low-power SRAM, or nvSRAM in systems demanding non-volatility without backup batteries. Choose the x16 I/O mode if byte-level data control is required; otherwise, utilize the x8 mode for simpler interfaces. Consider the 48FBGA, 44TSOP2, or 54TSOP2 packages based on available board space and thermal constraints within the industrial temperature range.

Memory IC Part Context

This part belongs to the Netsol S3R16(80)xxR1M series of 16Mb and 8Mb PPI MRAM devices. The series is designed to simplify system design by offering direct replacement capabilities for traditional volatile and non-volatile storage technologies. It is manufactured using STT-MRAM cells, providing high endurance and fast random access speeds suitable for demanding industrial and automotive-grade applications.

Memory IC Replacement Considerations

Datasheet lists S3R8008R1M, S3R1608R1M, S3R8016R1M, and S3R1616R1M as compatible variants within the same family. Verify pinout compatibility when substituting between densities or I/O modes. Ensure that the target application does not require voltage levels outside the 1.71V to 1.98V specification.
