The OTi-2118 presents a cost-effective device which complies with Universal Serial Bus specification rev.2.0 and ATA / ATAPI-6 specification rev 1.0. With OTi�s SOC design expertise, OTi-2118 is a single-chip solution providing the bridge function between the USB bus and IDE bus.
This controller can support various types of ATA/ATAPI devices, such as hard disk and compact flash device.
The OTi-2118 uses 12MHz crystal and slew-rate controlled pads to alleviate the EMI problem. By integrating PLL control circuit, RISC CPU, DMA controller, and USB interface controller, this device can certainly grant you optimal data throughput between the USB and IDE interfaces at a very low cost.
Features:
Complies with High-Speed USB 2.0 with built-in high/full-speed transceiver and SIE
Complies with ATA/ATAPI-6 specification rev 1.0
Complies with USB Storage Class specification ver.1.0. (Bulk only protocol)
Supports 4 endpoints: Control (0) / Bulk Read (1) / Bulk Write (2) / Interrupt (3).
64 / 512 bytes Data Payload for full / high speed Bulk Endpoint
Supports power down mode and USB suspend with wakeup capability
Supports 16-bit standard PIO mode interface
Supports 16-bit Multiword DMA mode and Ultra DMA mode interface (Ultra 33 / 66 / 100)
Configurable Vendor ID / Product ID (VID/PID)
ROM size: 12k words; RAM size: 256 bytes
12MHz external clock to provide better EMI 3.3V power input
64-pin and 100-pin of LQFP and TQFP package are available
