MB86E50
Targets: Computers & Peripherals
The Fujitsu MB86E50 targets external USB 3.0 dual-port RAID and non-RAID configurations. It supports RAID 0 (striping), RAID 1 (mirroring), JBOD ("just a bunch of disks"), and Dual LUN configurations. It also includes a high-speed encryption hardware engine.
The MB86E50 supports transfer speeds up to 5 Gbps. The device supports hot plugging of devices, and the USB attached SCSI (UAS) and Bulk-only Transport (BOT) protocols. The controller incorporates a high-performance 32-bit RISC microprocessor and an embedded SSCG to optimize SuperSpeed performance while reducing EMI. The MB86E50 includes full legacy support for high-speed USB (480Mbps) and full-speed USB (12Mbps) devices, and supports SATA Gen2i (3Gbps) and Gen1i (1.5Gbps), ATA, and ATAPI drives.
The MB86E50 is fabricated using the Fujitsu 65nm CMOS technology, offering low-power consumption and expandability. The bridge controller supports GPIOs including pulse width modulation, provides native command queuing (NCQ) functionality, and includes a serial peripheral interface (SPI) for serial Flash ROM and multiple SPI devices. The MB86E50 features a lead (Pb)-free (RoHS) design, customizable product and version identifiers, and a compact 68-pin QFN (0.4mm pitch, 8mm x 8mm) package for greater flexibility. Only one external crystal (25MHz) is required to use this device.
