The KL5KUSB110from Kawasaki , is a low cost, high speed Universal Serial Bus (USB) to ATAPI/IDE Controller. It's 16 bit RISC processor and built in BIOS ROM translates USB ATAPI host commands to a wide variety IDE storage devices such as, HDD, FD, CD-ROM, CD-WR, ZIP Drives LS120 drives. The KL5KUSB110's unique interface architecture to external serial flash EEPROM allows flexibility to upgrade and support a variety of IDE/ATAPI based disk drives, without changing peripheral hardware. This is accomplished when new functions are uploaded into the Serial EEPROM from the USB Host PC. The KL5KUSB110's Memory/GPIO bi-directional Port supports both 8 and 16 bit PIO modes. The USB port supports up to the maximum 12 Mbits/sec USB transfer rate. All USB protocol modes are supported; Isochronous ( up to 1024 bytes ), Bulk, Interrupt and Control. The KL5KUSB110 uses IDE as a physical interface, but commands to the external disk can be either IDE or ATAPI commands. ATA-1,2&3 based disk drives are also supported. The KL5KUSB110 device supports a wide variety of Disk drive solutions due to it's Maximum Disk drive throughput rate up to 1Mbytes/sec and comprehensive PnP USB/ATAPI drivers.
