FEMDRW032G-88A19

Memory IC Overview

The FEMDRW032G-88A19 is an industrial-grade embedded multimedia card (eMMC) manufactured by Longsys under the FORESEE brand. It complies with JEDEC eMMC 5.1 specifications and integrates NAND flash memory with a dedicated controller for wear-leveling, bad block management, and ECC. The device features a 153-ball FBGA package measuring 11.5 x 13.0 x 1.0 mm. It supports data bus widths of 1, 4, or 8 bits with transfer rates up to 400 MB/s in HS400 mode at 200 MHz. Operating voltage ranges from 2.7V to 3.6V for VCC and 1.7V to 1.95V or 2.7V to 3.6V for VCCQ. The operational temperature range is -40°C to +85°C.

Memory IC Feature Summary

• Complies with JEDEC eMMC 5.1 specification with backward compatibility to earlier versions.
• Integrates hardware ECC engine and global wear-leveling algorithms for data integrity and endurance.
• Supports sudden power-loss safeguard mechanisms to prevent data corruption during unexpected power failures.
• Includes boot partitions, RPMB support, and Field Firmware Update (FFU) capabilities.

Memory IC Applications

• Industrial control systems requiring reliable storage in harsh environments
• Automotive infotainment and telematics units
• Embedded computing platforms needing high-performance non-volatile storage

Memory IC Procurement Notes

Verify the specific part number suffix against official Longsys documentation to confirm package dimensions and electrical characteristics. Ensure that the ordering information matches the exact capacity and interface requirements. Confirm compliance with RoHS directives and check for any recent revisions to the datasheet that may affect pin configurations or firmware updates.

Memory IC Selection Notes

Select this component when an embedded solution compatible with eMMC 5.1 is required for industrial applications. Consider the 153-ball FBGA package size for PCB layout constraints. Evaluate the need for HS400 high-speed modes and verify that the host controller supports the necessary voltage levels for VCC and VCCQ. Assess thermal management requirements given the wide operating temperature range.

Memory IC Part Context

This component belongs to the FORESEE Industrial eMMC series, which includes variants with different capacities such as 64GB and 128GB models sharing similar form factors and interface standards. These devices are designed to provide robust storage solutions for demanding environments where reliability and performance consistency are critical. The series emphasizes long service life and resistance to environmental stressors.

Memory IC Replacement Considerations

Direct substitutes include other FORESEE eMMC models within the same product line, such as FEMDRW064G-88A19 or FEMDRW128G-88A19, provided capacity differences are acceptable. Cross-brand replacements must be evaluated carefully to ensure compatibility with eMMC 5.1 specifications and physical package dimensions.
