Biwin Storage Embedded Storage

eMMC and UFS are embedded storage standards with different performance characteristics: (1) Interface - eMMC uses parallel interface, UFS uses high-speed serial M-PHY

(2) Speed - UFS 3.1 reaches 2100MB/s vs eMMC 5.1's 400MB/s

(3) Architecture - UFS uses full-duplex command queue, eMMC is half-duplex

(4) Power - UFS is more power efficient per MB transferred

(5) Cost - eMMC is more cost-effective for budget applications

(6) Use case - eMMC for IoT and entry-level mobile, UFS for flagship smartphones and automotive. UFS is the successor to eMMC and is becoming standard in high-performance embedded applications.

Choose UFS for high-performance applications. eMMC is cost-effective for IoT and entry-level devices.

Biwin embedded storage comes in various package options: (1) BGA-153 (11.5x13mm) - Standard eMMC package, widely used

(2) BGA-169 (12x16mm) - Larger eMMC with more balls for enhanced routing

(3) BGA-153 (11x10mm) - Compact eMMC for space-constrained designs

(4) BGA-153 (9x7.5mm) - Smallest eMMC for wearables

(5) BGA-153 UFS - Standard UFS package

(6) BGA-95 UFS - Compact UFS option. Package selection depends on PCB space, routing complexity, and thermal considerations. All packages are surface-mount and require proper PCB layout for signal integrity.

Select package based on PCB space and routing requirements. Contact FAE for layout guidance.

Biwin provides long-term supply commitment for embedded storage products: (1) Standard commitment - 3-5 years for most industrial products

(2) Extended commitment - 5-10 years available for automotive and medical applications

(3) Last-time buy notification - 6-12 months notice before discontinuation

(4) Form-fit-function replacements - compatible alternatives when needed

(5) Revision control - notification of any firmware or hardware changes

(6) PCN process - formal process for product change notifications. Long-term supply agreements (LTSA) can be negotiated for high-volume applications. This commitment is crucial for industrial, automotive, and medical devices with long product lifecycles.

Contact LiTong to discuss LTSA for long-term supply requirements.

Biwin embedded storage supports various temperature ranges: (1) Consumer grade - 0°C to +70°C for mobile and consumer devices

(2) Industrial grade - -40°C to +85°C for industrial IoT and automotive

(3) Automotive grade - -40°C to +105°C for automotive infotainment

(4) Extended range - Custom ranges available for specific applications. Temperature affects performance and endurance - higher temperatures accelerate wear. Industrial and automotive products use qualified components and undergo extended temperature cycling testing. For outdoor or harsh environment applications, industrial grade is recommended. Contact LiTong FAE for specific temperature qualification requirements.

Choose temperature grade based on operating environment. Industrial grade for harsh conditions.

Integrating Biwin embedded storage requires attention to: (1) PCB layout - follow manufacturer guidelines for BGA routing and via placement

(2) Decoupling - place capacitors close to power pins

(3) Signal integrity - match trace lengths for high-speed signals

(4) Thermal management - consider thermal vias for heat dissipation

(5) Manufacturing - use proper reflow profile for BGA packages

(6) Testing - implement boundary scan for production testing

(7) Firmware - integrate host driver for eMMC/UFS protocol. Biwin provides reference designs and layout guidelines. LiTong FAE offers design review services to ensure successful integration and optimal performance.
