W-USB-IDE USB to IDE External Case

W-USB-IDE USB to IDE External Case
Features:
	Up to 16 bit Programmable Bi-directional Data I/O or DMA port, including Memory port is used as the main IDE port. Data is moved in PIO mode either in 8 or 16 bit mode
	SL11- R can use 12 MHz external crystal or clock. Other clocks such as 48 MHz are generated by built-in DPLL ( Digital PLL )
	Max disk operating throughput rate is up to 1Mbytes/sec, includes USB overhead
	Up to 24 bit General Purpose I/O (GPIO) channels
	Suspend, Resume and Low Power modes.
	3Kx16 internal Mask BIOS ROM, supports USB to ATAPI/IDE macros, USB functions, serial EEPROM programmability, DRAM, UART, and other func-tions. Executable code can run from either internal RAM, ROM, or external ROM. Also, available ex-tended external SRAM or DRAM to store disk cash data
	3Kx8 internal general purpose SRAM buffer. Mem-ory buffer can be configured as “Double port buffer” multiple sector data buffer, 512 bytes or 1024 bytes simultaneously transferred from Disk to USB port and via versa
	Support for variety of DISK specific functions or pro-tocol is available by downloading specific related code via the USB port for it to be automatically pro-grammed into external serial flash EEPROM, by the BIOS ROM
	USB Port (12Mbits/sec) including built-in USB transceiver. All USB standard protocol modes are supported; Isochronous mode (up to 1024 packet size), Bulk, Interrupt and Control modes
	Four end points. Each endpoint utilizes a bi-directional DMA port to move data to/from the USB port to/from internal Memory buffer. Indepen-dently, data can be sent/received by external device
	Package: 100 LPQFP, 0.5 micron
	VDD : 3.3VDC
	Chips: Scanlogic
