DATA SHEET O K I A S I C P R O D U C T S Z0122 (2-port) and Z0100 (4-port) USB 1.1 Host Controllers Virtual Component Soft IPs December 2001 PLAT-7C ARM7TDMI“ -Based Integration Platform Oki Semiconductor Oki Semiconductor Z0122 (2-port) and Z0100 (4-port) USB 1.1 Host Controllers (Virtual Component Soft IPs) FUNCTIONAL DESCRIPTION Oki Semiconductor’s Z0122 and Z0100 USB 1.1 Host Controllers (2-port and 4-port respectively) are designed to manage the control and data flow between the host and the USB device, and collect the status / activity statistics. There are five major blocks in the Z0122 and Z0100 USB 1.1 Host Controllers: • • • • • The HCI Master block handles all the read / writes initiated by the Host Controller to the system memory. The HCI Slave block is the interface between the OHCI operational registers and the application. The List Processor block has multiple state machines to implement List Service Flow, List Priority, USB – states, ED, TD services, Status write Back, TD retirement etc. as per the OHCI specification. The Root Hub acts as wrapper around HSIE and interfaces with Host Controller’s List Processor block, FIFO and OHCI Registers. The Root Hub Port Configuration block implements the part of the OHCI Registers that are specific to the Root Hub and a state machine for every Down Stream Port to control the port functional states. FEARURES • Open HCI Rev 1.0 compliant • USB Rev 1.1 compliant. • Root Hub is user configurable (e.g. number of Down Stream Ports, Power Switching Options, etc) • Support low (1.5Mhz) and high (12Mhz) speed USB devices • No bi-directional or tri-state buses • No level sensitive latches • User friendly application bus interface • Hooks for legacy device support, with the Support of SMI (System Management Interrupt) pin. APPLICATION • For all USB application such as printers, digital cameras, external cable modems, game controllers, keyboards, etc SYSTEM BLOCK DIAGRAM App_sadr 6 Rcfg_regdata 32 HCI SLAVE BLOCK App_sdata 32 control Hci_data 32 H C I control control USB STATE CONTROL ROOT HUB & HOST SIE Cntl OHCI REGS control LIST PROCES SOR BLOCK TxEnl PORT S/M TxDpls PORT S/M TxDmns ctrl Ed/Td_status 32 ED & TD REGS Hcm_adr/data 32 control Hc data 8 Df_data 8 Ext.FIFO Status Rcvdata ctrl HSIE S/M HCI MASTER BLOCK status 64x8 FIFO CNTL Hcf_data 8 x v r 1 USB ROOT HUB CONFIG BLOCK Rcvdpls Rcvdmns Rh_data 8 USB DPLL PORT S/M Df_data 8 FIFO_data 8 FIFO 64x8 Clock MUX 12/1_5 USB x v r 2 Ed/Td_data 32 App_mdata 32 B U S OHCI ROOT HUB REGS x v r 15 CHARACTERISTIC Operating Conditions Parameter 0.25 µm 0.16 µm Units Min Typ Max Min Typ Max Power supply voltage 2.25 2.5 2.75 1.65 1.8 1.95 V Junction temperature (Tj) - 40 25 125 - 40 25 125 °C - - - - - - mA / MHz 48 MHz AC power consumption Clock frequency 48 Estimated Gate Count Parameter Gate count Logic pin count 0.25 µm 0.16 µm NDP = 2 NDP = 4 47.204 54.321 196 220 Units KG Note: 1.
