JSMC08AUM1ASAEA-H5-SU

Memory IC Overview

The JSMC08AUM1ASAEA-H5-SU is an 8GB embedded MultiMediaCard (eMMC) device compliant with the JEDEC eMMC 5.1 standard, backward compatible with versions 4.5 and 5.0. It integrates NAND flash and a controller within a 11.5 x 13.0 x 1.0 mm 153-ball BGA package. The device utilizes a single 3V supply for the NAND area via VCC and supports dual 1.8V or 3V supplies for the controller via VCCQ. Key specifications include HS400 interface support at 200MHz clock frequency with an 8-bit bus width, achieving up to 400 MB/s bus speed. Sustained sequential read performance reaches 140 MB/s, while write performance reaches 80 MB/s under specific test conditions.

Memory IC Feature Summary

• Supports HS400 DDR interface timing mode for high-speed data transfer
• Includes Flash Translation Layer (FTL) for wear leveling and bad block management
• Features programmable bus widths of 1-bit, 4-bit, and 8-bit
• Provides secure delete capabilities including Sanitize, Secure Erase, and Secure Trim

Memory IC Applications

• Embedded NAND flash applications requiring high reliability
• Systems utilizing Field Firmware Upgrade (FFU) mechanisms
• Devices requiring partition management with Boot and RPMB areas
• Applications needing auto power saving modes for efficiency

Memory IC Procurement Notes

Verify that the host system supports the required voltage levels for VCCQ, specifically 1.70V to 1.95V for HS400 mode operation. Confirm compatibility with eMMC 5.1 standards and ensure the host controller can handle the specified bus frequencies. Check for any specific ordering suffix requirements if industrial temperature ranges are needed, as this part is designated for commercial use.

Memory IC Selection Notes

Select this component when an 8GB capacity is required in a compact 153-ball BGA form factor. Ensure the application environment operates within the commercial temperature range of -25°C to 85°C. Consider the need for HS400 interface support and verify that the host system can manage the dual supply voltage configuration for optimal performance and power consumption.

Memory IC Part Context

This device belongs to the JSC embedded flash product line, designed for applications demanding high performance and reliability. It incorporates advanced flash management software to ensure data integrity through strong ECC and wear leveling. The product architecture separates memory power from controller power, allowing for flexible power management strategies in embedded systems.

Memory IC Replacement Considerations

The datasheet lists the JSMC08AUM1ASAEA-H5I-SU as a similar level part with the same pinout and package, differing primarily in the operating temperature range which extends to -40°C for industrial applications.
