| MOTOROLA Freescale Semiconductor, Inc. Order this document by MC141556 SEMICONDUCTOR TECHICAL DATA Product Preview USB Hub Controller CMOS This device is a self-contained USB Hub which complies with USB Hub spec Rev 1.0. This device is used to expand the USB ports of your PC system while needed. Because of its self-contained and bus-powered/self-powered capability, it can hide the complexity from the user and be flexibly placed anywhere, such as monitor, keyboard, motherboard, hub-box, etc. The MC141556 consists of Serial Interface Engine(SIE), Hub Repeater, and Hub Controller, supporting one upstream port and up to five downstream ports. It also provides optional IIC(M_BUS) programmable Vendor ID and Product ID. Both Low speed mode (1.5 Mbps) and Full speed mode (12 Mbps) are supported by automatically detecting which data line (D+ or D-) is pulled high whenever downstream devices are connected to the bus or at power-up. MC141556 can be self-powered or bus-powered. When self-powered, MC141556 is powered by external 5 volt supply and capable of delivering 500mA current to each downstream port. Power management for all downstream ports supports power-switching and overcurrent detection with Individual or Ganged control; a self-powered MC141556 supports Individual control only, but bus-powered MC141556 supports either Individual or Ganged control. When Ganged control, PWRSW1 and OVR1 are dedicated for power management. IIC(M_BUS) interface is provided to set up customized Vendor ID, Product ID, Power Mode, Power Management Mode, Number of Downstream Ports and Overcurrent Debounce Setting.

PIN DESCRIPTION VDD (Pin 1) This is the +5V power pin of the chip. OSC1 (Pin 2), OSC2 (Pin 3) The OSC1 and OSC2 pins are the connections for the onchip oscillator. The crystal frequency is 24MHz . OSC1 may be driven by an external oscillator if an external crystal circuit is not used. VSS (Pin 4) This is the ground pin of the chip. IICEN (Pin 5) This is an input pin which requires the default input state to determine the IIC Mode of Hub controller. During PowerOn Reset, pulling IICEN high configures MC141556 as a IIC slave to allow customized parameters programmable. Pulling this pin low disables IIC Mode and adopts default parameters. See Table1 Configuration selection for detail. DP0 (Pin 6) This is the upstream differential data plus I/O pin of the Hub. DM0 (Pin 7) This is the upstream differential data minus I/O pin of the Hub. VDD 3CAP (Pin 8) This pin must connect an external capacitor for the internal 3.3V regulator which supply transceivers of all USB ports. OVR1 (Pin 9) This is the over-current detection pin of the downstream port 1. Active low is to indicate overcurrent condition occurs. In GANG mode, OVR1 is the common detection pin for all the four downstream ports. PWRSW1 (Pin 10) This is an output pin which can be used to switch on/off the external power regulator for the downstream port 1. Active high is to switch on the power. In GANG mode, PWRSW1 is the common output pin for all the four downstream ports. DP1 (Pin 11) This is the differential data plus I/O pin of the downstream port 1. DM1 (Pin 12) This is the differential data minus I/O pin of the downstream port 1. OVR2 (Pin 13) This is the over-current detection pin of the downstream port 2. Active low is to indicate overcurrent condition occurs. PWRSW2 (Pin 14) This is an output pin which can be used to switch on/off the external power regulator for the downstream port 2. Active high is to switch on the power. DP2 (Pin 15) This is the differential data plus I/O pin of the downstream port 2. DM2 (Pin 16) This is the differential data minus I/O pin of the downstream port 2. OVR3 (Pin 17) This is the over-current detection pin of the downstream port 3. Active low is to indicate overcurrent condition occurs. PWRSW3 (Pin 18) This is an output pin which can be used to switch on/off the external power regulator for the downstream port 3. Active high is to switch on the power. DP3 (Pin 19) This is the differential data plus I/O pin of the downstream port 3. DM3 (Pin 20) This is the differential data minus I/O pin of the downstream port 3. OVR4 (Pin 21) This is the over-current detection pin of the downstream port 4. Active low is to indicate overcurrent condition occurs. PWRSW4 (Pin 22) This is an output pin which can be used to switch on/off the external power regulator for the downstream port 4. Active high is to switch on the power. DP4 (Pin 23) This is the differential data plus I/O pin of the downstream port 4. DM4 (Pin 24) This is the differential data minus I/O pin of the downstream port 4. OVR5/GANG/SCL (Pin 25) When IIC Mode: this input pin acts as SCL, which is the synchronizing clock input from the transmitter for IIC protocol. (Detailed description of the programming protocol will be discussed in the IIC Communication section). When non-IIC Mode: if self-powered, this input pin acts as OVR5, which is overcurrent detection of downstream port 5; active low is to indicate overcurrent occurs. If bus-powered, this input pin acts as GANG to determine Power Control Mode; pulling this pin low configures the Hub as Ganged control, and pulling it high as Individual control. PWRSW5/SDA (Pin 26) When IIC Mode: this pin acts as SDA, which is a unidirectional data line for IIC protocol. (Detailed description of the programming protocol will be discussed in the IIC Communication section). When non-IIC Mode: if self-powered, this output pin is to switch on/off the external power regulator for downstream port 5; active high is to switch on the power. Freescale Semiconductor, Inc... MC141556 6 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. DP5/SEL1 (Pin 27) When IIC Mode: this pin acts as differential data plus I/O pin of downstream port 5 for internal use; that is, there are no PWRSW5 and OVR5 for downstream port 5. When non IIC Mode: in Initialization, this pin, along with SEL0 and OVR5, determines Power Mode and Power Control Mode. (refer to Table1 for detail) After Initialization, if self-powered, this pin is differential data plus I/O pin of downstream port 5. DM5/SEL0 (Pin 28) When IIC Mode: this pin acts as differential data minus I/ O pin of downstream port 5 for internal use; that is, there are no PWRSW5 and OVR5 for downstream port 5. When non-IIC Mode: in initialization, this pin, along with SEL1 and OVR5, determines Power Mode and Power Control Mode. (refer to Table1 for detail) After initialization, if self-powered, this pin is differential data minus I/O pin of downstream port 5; if bus-powered, pull this pin high. If MC141556 is programmed as a five-downstream-port hub, DP5/SEL1 acts as the differential data plus I/O pin of downstream port 5, and DM5/SEL0 as the differential data minus I/O pin. OVR5/GANG/SCL acts as the SCL line for IIC communication, and PWRSW5/SDA acts as SDA line for IIC communication. If MC141556 is programmed as a four-downstream-port hub, DP5/SEL1 and DM5/SEL0 have no further usage. OVR5/GANG/SCL and PWRSW5/SDA are dedicated to IIC communication. Freescale Semiconductor, Inc... (b) Self-powered Mode with Individual control (Monitor Application) During Power-On Reset, pull IICEN, DP5/SEL1 and DM5/ SEL0 low to select this mode. Meanwhile, MC141556 is configured to be self-powered with 5 downstream ports whose power management is in Individual control; that is, after Power-On Reset, DP5/SEL1 acts as DP5, DM5/SEL0 acts as DM5, OVR5/GANG/SCL acts as OVR5 and PWRSW5/ SDA acts as PWRSW5. (c) Bus-powered Mode with Individual control SYSTEM DESCRIPTION MC141556 is booted up from the Power-On Reset which will initialize all the internal hardware circuitry and reset the program counter of the internal processor. During Power-On Reset, MC141556 must be set to the desired configuration by the input states of the pins IICEN, OVR5/GANG/SCL, PWRSW5/SDA, DP5/SEL1 and DM5/SEL0. See Table1 Configuration Selection for detail. After Power-On, the Hub Repeater will handle the connectivity in per packet basis, and all downstream ports transition to the powered off state. After all initialization, the Hub Controller takes over the responsibility for receiving Host' s commands, Downstream Power Management and to report status in per port basis while Repeater is detecting the connectivity of each downstream port. MC141556 accepts the Host Reset request to generate a per port reset and receives reset signalling from root port to complete its own reset sequence. During Power-On Reset, pull IICEN and DP5/SEL1 low, pull OVR5/GANG/SCL and DM5/SEL0 high to select this mode. Meanwhile, MC141556 is configured to be bus-powered with 4 downstream ports whose power management is in Individual control; that is, after Power-On Reset, DP5/ SEL1, DM5/SEL0, OVR5/GANG/SCL and PWRSW5/SDA have no further usage. (d) Bus-powered Mode with Ganged control During Power-On Reset, pull IICEN, DP5/SEL1 and OVR5/GANG/SCL low, pull DM5/SEL0 high to select this mode. Meanwhile, MC141556 is configured to be bus- powered with 4 downstream ports whose power management is in Ganged control. In this mode, only PWRSW1 and OVR1 are dedicated to power management for all the 4 downstream ports. All the four operating modes, with pin input states during Power-On Reset, are summarized in Table1 . HUB CONFIGURATION MC141556 can be configured as one of the four operating modes: IIC Mode, Self Power Mode with Individual Control, Bus Power Mode with Individual Control, Bus Power Mode with Ganged Control. (a) IIC Mode During Power-On Reset, pull IICEN pin high to select this mode. OVR5/GANG/SCL acts as SCL which is the synchronizing clock input from the transmitter for IIC protocol. PWRSW5/SDA acts as SDA which is the uni-directional data line for IIC protocol. In this mode, Vendor ID, Product ID, Powered Mode, Number of Downstream Ports, Power Management Mode and Debounce Setting are programmable by an external MCU. Table 1.

COMMUNICATION PROTOCOL CHIP ADDRESS DATA BYTES ACK IIC Communication Protocol This is a two-wire serial communication link that is fully compatible with the IIC bus system. It consists of SDA bidirectional data line and SCL clock input line. Data is sent from a transmitter (master), to a receiver (slave) via the SDA line, and is synchronized with a transmitter clock on the SCL line at the receiving end. The maximum data rate is limited to 400kbps. The default chip address is $70. Please refer to the IIC-Bus specification for the detail timing requirement. Operating Procedure FIGURE 7. shows the IIC transmission format. The master initiates a transmission routine by generating a START condition, followed by a slave address byte. Once the address is properly identified, the slave will respond with an ACKNOWLEDGE signal by pulling the SDA line LOW during the ninth SCL clock. Each data byte which then follows must be eight bits long, plus the ACKNOWLEDGE bit, to make up nine bits together. Appropriate hub setting information can be downloaded sequentially. See Data Transmission Format for details. In the cases of no ACKNOWLEDGE or completion of data transfer, the master will generate a STOP condition to terminate the transmission routine. SDA ACK SCL 1 2-7 8 9 START CONDITION STOP CONDITION Figure 7. IIC FORMAT DATA TRANSMISSION FORMAT After the proper identification by the receiving device, Master is now ready to program MC141556 by transmitting the configuration data. The configuration data is shown in Table2 Programmable Configuration Data. To complete the programming sequence, all six bytes of data are needed to be transmitted. The transmission sequence is defined in Table2 . An ACKNOWLEDGE bit must be inserted between each byte of data as shown in FIGURE 8. Freescale Semiconductor, Inc... Table 2.
