JSMC04AUM1ASAED-H5

The JSMC04AUM1ASAED-H5 is a 32 Gbit (4GB) embedded MultiMediaCard (eMMC) storage device from Jeju Semiconductor. It implements NAND (MLC) flash in an eMMC 5.1 interface and is offered as a surface-mount 153-FBGA package (supplier package: 153-BGA, 8.0 × 10.0 mm).

Designed for embedded solid-state storage, this commercial-grade eMMC supports features documented for the series such as HS400 signaling, partition management and secure operation. Key value comes from its standard eMMC 5.1 interface, compact package, and support for common storage management and security functions published in the product series datasheet.

Key Features

• Memory Core  32 Gbit (4GB) non-volatile NAND flash (MLC) providing embedded solid-state storage capacity.
• Standard Interface  eMMC 5.1 interface for host integration; the series datasheet includes HS400 interface support for high-speed modes.
• Clocking  200 MHz clock frequency specified for device operation.
• Power  3.3 V supply voltage as specified for device operation.
• Package & Mounting  Surface-mount 153-FBGA package (supplier device package: 153-BGA, 8.0 × 10.0 mm) for compact board-level integration.
• Temperature & Grade  Commercial grade operation with an operating temperature range of -25 °C to 85 °C.
• Storage Management & Security  Series technical documentation includes partition management (boot area and RPMB), secure delete support (sanitize, secure erase, secure trim), packed commands, and device health reporting.
• Field & Performance Features  Series-level features documented include Field Firmware Upgrade (FFU), cache management, high-priority interrupt (HPI), auto power saving modes, and extended CSD register support for device configuration and performance tuning.
• Compliance  RoHS compliant.

Typical Applications

• Embedded storage systems  Use as onboard non-volatile flash storage where eMMC 5.1 compatibility is required.
• Compact electronic modules  Low-profile 153-FBGA package fits space-constrained board designs that require surface-mount flash memory.
• Commercial-grade equipment  Suitable for systems that operate within the -25 °C to 85 °C range and require standard eMMC storage management features.

Unique Advantages

• Standardized eMMC 5.1 interface  Simplifies host integration with a widely adopted storage interface and documented HS400 support for high-speed modes.
• Embedded NAND MLC capacity  32 Gbit (4GB) MLC NAND provides a balance of density and endurance characteristics suitable for many embedded applications.
• Compact, surface-mount package  153-FBGA (153-BGA, 8.0 × 10.0 mm) enables compact board layouts and straightforward assembly.
• Operational robustness  Commercial-grade temperature range and RoHS compliance help meet regulatory and thermal requirements for mainstream embedded products.
• Series-level management and security features  Partition management, secure delete options, device health reporting, and field firmware upgrade capabilities support maintainability and secure operation.
