S3A1604R0M-JI1AT

Memory IC Overview

The Netsol S3A1604R0M-JI1AT is a 16Mb SPI MRAM device utilizing STT-MRAM technology. It operates on a single 1.8V supply (1.71V to 1.98V) and supports Single, Dual, and Quad SPI interfaces with Mode 0 and Mode 3. The component achieves up to 108MHz in SDR mode and 54MHz in DDR mode. It provides unlimited read endurance and 10^14 write cycles with data retention exceeding 10 years at 85°C. The chip includes an augmented 256-byte nonvolatile area, hardware write protection, block lock features, and a unique 64-bit ID.

Memory IC Feature Summary

• Supports XIP for both read and write operations
• Features fast write time allowing single byte writable capability
• Includes augmented 256-byte nonvolatile area with user protection
• Provides deep power down mode for low-power consumption

Memory IC Applications

• Industrial control systems requiring high endurance
• Smart devices needing fast cache storage
• Applications replacing traditional flash or EEPROM
• Equipment requiring reliable non-volatile data logging

Memory IC Procurement Notes

Verify the specific suffix 'JI1AT' against official ordering tables to confirm package type and temperature grade. Ensure the design accommodates the 1.8V operating voltage range of 1.71V to 1.98V. Confirm interface compatibility with the host controller's SPI modes. Check for RoHS compliance requirements relative to the selected package.

Memory IC Selection Notes

Select this model when 16Mb density and 1.8V logic levels are required. Choose over V0M variants if lower voltage operation is necessary. Consider the WSON or SOIC packages based on board space constraints. Verify that the host system supports the required SPI clock frequencies and modes for optimal performance.

Memory IC Part Context

This part belongs to the S3Axx04x0M family of SPI MRAM devices from Netsol Corporation. It shares architectural similarities with other densities in the series, such as 1Mb to 8Mb options. The R0M designation indicates the 1.8V voltage variant, distinguishing it from the 3.3V V0M versions within the same product line.

Memory IC Replacement Considerations

Direct substitutes include other Netsol S3A1604R0M variants with compatible suffixes. Cross-brand replacements require verifying pinout compatibility and SPI command set alignment. Ensure replacement parts match the 1.8V supply requirement and industrial temperature range specifications.
