• 200 MHz Clock Frequency - Supports data transfer rates up to 200 MHz, enabling efficient read and write operations for applications requiring responsive storage access.
• Industrial Temperature Range - Qualified for operation from -40°C to 85°C, ensuring reliable performance in harsh environmental conditions typical of industrial, automotive, and outdoor applications.
• Compact 153-VFBGA Package - Housed in a space-efficient 11.5mm x 13mm very fine-pitch ball grid array package, minimizing board space requirements in size-constrained embedded designs.
• Wide Voltage Operation - Functions across a 2.7V to 3.6V supply range, providing compatibility with various system power architectures and supporting low-power design strategies.

Typical Applications

• Industrial Control Systems - This eMMC module provides reliable program storage and data logging for PLCs, industrial PCs, and HMI systems where the pSLC technology ensures extended write endurance for frequent configuration updates and operational data recording.
• Automotive Infotainment and Telematics - The industrial temperature rating and managed NAND architecture make this device suitable for in-vehicle systems that require persistent storage for maps, media content, and vehicle diagnostics in environments subject to wide temperature variations.
• Medical Devices - Embedded medical equipment benefits from the integrated wear leveling and error correction capabilities, ensuring data integrity for patient records and device configurations while the compact package fits space-constrained portable and bedside instruments.
• Network Infrastructure Equipment - Routers, switches, and wireless access points utilize this eMMC for boot code, configuration storage, and firmware updates where the managed interface reduces software complexity and the industrial temperature range supports equipment deployed in uncontrolled environments.
• Smart Metering and IoT Gateways - The combination of moderate capacity, low power operation, and extended temperature tolerance makes this memory suitable for utility meters and IoT edge devices that must operate reliably for years in outdoor installations while logging consumption data.

Unique Advantages

• Simplified Integration with Managed NAND: The integrated eMMC controller eliminates the need for external NAND management software, reducing development time and minimizing the risk of data corruption from improper wear leveling or bad block handling.
• Enhanced Endurance Through pSLC Technology: Pseudo-single-level cell flash architecture provides significantly higher program/erase cycle endurance compared to MLC or TLC alternatives, extending product lifespan in write-intensive applications and reducing warranty costs.
• Reduced BOM and PCB Complexity: The single-chip solution with integrated controller and flash reduces component count, simplifies board layout, and minimizes the PCB footprint compared to discrete NAND flash implementations requiring external controllers.
• Industrial-Grade Reliability: The extended -40°C to 85°C operating temperature range ensures consistent performance in demanding environments without requiring additional thermal management, lowering system cost and complexity.
• Standards-Based Compatibility: eMMC 5.1 compliance ensures interoperability with a broad range of host processors and established software drivers, facilitating design reuse and providing flexibility for future platform migrations.
• Efficient Power Management: The wide 2.7V to 3.6V operating range supports diverse power supply architectures and enables dynamic voltage scaling strategies to optimize power consumption in battery-powered or energy-sensitive applications.
