S3R3216R1M-XI70T

Memory IC Overview

The Netsol S3R3216R1M-XI70T is a 32Mb Parallel Peripheral Interface MRAM utilizing STT-MRAM technology. It operates on a single 1.8V supply (1.71V to 1.98V) and supports x16 I/O mode with independent lower and upper byte control via LB and UB pins. The device features 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 per page, with data retention of 10 years at 85°C. Available in industrial temperature range (-40°C to 85°C), it comes in 48FBGA and 54TSOP2 packages.

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 asynchronous page mode for enhanced read performance.
• Enables independent access to lower and upper bytes through specific data byte control signals.
• Designed for high reliability with virtually unlimited read endurance and extended data retention capabilities.

Memory IC Applications

• Industrial code storage applications requiring non-volatile retention.
• Real-time data logging systems needing high write endurance.
• Backup memory solutions replacing traditional FRAM or nvSRAM.
• Working memory in industrial designs where power loss protection is critical.

Memory IC Procurement Notes

Verify the specific voltage variant required, as the R suffix denotes the 1.8V version while V denotes 3.3V. Confirm package selection between 48FBGA and 54TSOP2 matches the target PCB layout. Ensure power sequencing adheres to datasheet recommendations, specifically maintaining Chip Select high during power-up to prevent abnormal writes. Check RoHS compliance status for the specific manufacturing batch.

Memory IC Selection Notes

Select this component when system design requires non-volatile memory with SRAM-like speed and FRAM-like endurance. The 1.8V operating voltage makes it suitable for low-power embedded systems. Consider the x16 interface width and page mode capabilities if high-throughput sequential data access is needed. Verify that the industrial temperature range meets environmental requirements for the deployment location.
