S3A4004R0M-JI1ATD0

Memory IC Overview

The S3A4004R0M-JI1ATD0 is a 4Mb SPI MRAM device utilizing STT-MRAM technology. It operates on a single 1.8V supply (1.71V to 1.98V) and supports SDR frequencies up to 108MHz and DDR up to 54MHz. The component features XIP, deep power down current of 25µA, and unlimited read endurance with 10^14 write cycles. It includes a 64-bit unique ID, user-writable serial number, and an augmented 256-byte protected area.

Memory IC Feature Summary

• Supports Single, Dual, and Quad SPI interface modes including XIP for read and write operations
• Features hardware data protection via WP pin and block lock mechanisms alongside nonvolatile configuration registers
• Provides identification capabilities through a 64-bit unique ID and a user-writable 64-bit serial number register

Memory IC Applications

• Industrial control systems requiring high endurance and low voltage operation
• Embedded applications needing fast single-byte write capabilities
• Systems utilizing execute-in-place (XIP) functionality for code execution

Memory IC Procurement Notes

Verify the specific suffix codes against the official Netsol ordering table to confirm package type and temperature grade. Ensure the design accommodates the 1.8V operating range and SPI timing requirements. Confirm RoHS compliance status for the selected package variant before finalizing procurement specifications.

Memory IC Selection Notes

Select this component for designs requiring non-volatile memory with high write endurance and low power consumption. The 1.8V version is suitable for low-voltage logic interfaces. Consider the available packages such as WSON or SOIC based on board space constraints and thermal management needs.

Memory IC Part Context

This part belongs to the S3Axx04x0M family of 1Mb to 16Mb SPI MRAM devices from Netsol Corporation. The family offers density options ranging from 1Mb to 16Mb with both 3.3V and 1.8V variants. The S3A4004R0M specifically denotes the 4Mb density with 1.8V operation.

Memory IC Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other STT-MRAM SPI devices from different manufacturers that match the 4Mb density, 1.8V supply, and 108MHz SDR speed requirements.
