S3A4004R0M-AI1AT

Memory IC Overview

The Netsol S3A4004R0M-AI1AT is a 4Mb SPI MRAM component utilizing STT-MRAM technology. It operates on a single 1.8V supply (1.71V–1.98V) and supports Single Data Rate (SDR) frequencies up to 108MHz and Double Data Rate (DDR) up to 54MHz. The device features Quad SPI (4-4-4) interface modes, Execute In Place (XIP), and deep power down current of 25µA. It offers unlimited read endurance, 10^14 write cycles, and 10-year data retention at 85°C. Available in 8-pad WSON (5.0mm x 6.0mm) and 8-pin SOIC packages.

Memory IC Feature Summary

• Supports Single, Dual, and Quad SPI interface modes with XIP capability for efficient code execution.
• Features nonvolatile status registers, block lock protection, and a unique 64-bit identification system.
• Includes an augmented 256-byte nonvolatile area with user-protection capabilities.
• Provides fast single-byte writable operations without requiring external error correction codes.

Memory IC Applications
