It supports all USB2.0 data rates (High-Speed 480Mbps, Full-Speed 12 Mbps and Low-Speed 1.5Mbps) in both Host and Peripheral modes. It additionally supports a UART mode and legacy ULPI serial modes. TUSB1211 also supports USB Battery Charging Specification Ver1.1. integrating a charger detection module for sensing and control on DP/DM lines, and ACA (Accessory Charger Adapter) detection and control on ID line. ACA allows simultaneous connection of a USB Charger or Charging Downstream Port and an Accessory to a portable OTG device. Configuration bits allow an ACA-agnostic legacy link to correctly communicate with the connected accessory Port through the ACA. TUSB1211 also supports the OTG (Ver1.3) optional addendum to the USB2.0 specification, including Host Negotiation Protocol (HNP) and Session Request Protocol (SRP). TUSB1211 is optimized to be interfaced through a 12-pin SDR UTMI Low Pin Interface (ULPI), supporting both input clock and output clock modes, with 1.8 V interface supply voltage. TUSB1211 integrates a 3.3 V LDO, which makes it flexible to work with either battery operated systems or pure 3.3 V supplied systems. Both the main supply and the 3.3 V power domain can be supplied through an external switched-mode converter for optimized power efficiency. TUSB1211 includes a POR circuit to detect supply presence on VBAT and VDDIO pins. TUSB1211 can be disabled or configured in low power mode for energy saving. TUSB1211 is protected against accidental shorts to 5 V or ground on its exposed interface (DP/DM/ID). It is also protected against up to 20 V surges on VBUS. TUSB1211 integrates a high-performance low-jitter 480 MHz PLL and supports two clock configurations. Depending on the required link configuration, TUSB1211 supports both ULPI input and output clock mode : input clock mode, in which case a square-wave 60 MHz clock is provided to TUSB1211 at the ULPI interface CLOCK pin; and output clock mode in which case TUSB1211 can accept a square-wave reference clock at REFCLK of either 19.2 MHz, 26 MHz. Frequency is indicated to TUSB1211 via the configuration pin CFG. This can be useful if a reference clock is already available in the system.

Depending on the clock configuration, this reference clock can be provided either at REFCLK pin or at CLOCK pin. By default CLOCK pin is configured as an input. Two clock configurations are possible: • Input clock configuration (see Section 5.1.1) • Output clock configuration (see Section 5.1.1) 5.1.1 ULPI Input Clock Configuration In this mode REFCLK must be externally tied to GND. CLOCK remains configured as an input. When the ULPI interface is used in “input clock configuration”, i.e., the 60 MHz ULPI clock is provided to TUSB1211 on CLOCK pin, then this is used as the reference clock for the 480 MHz USB PLL block.

When an input clock is detected on REFCLK pin then CLOCK will automatically change to an output, i.e., 60 MHz ULPI clock is output by TUSB1211 on CLOCK pin. Two reference clock input frequencies are supported. REFCLK input frequency is communicated to TUSB1211 via a configuration pin, CFG, see FREFCLK in Table 5-2 for frequency correspondence. TUSB1211 supports square-wave reference clock input only. Table 5-2.

See 9.3.3.1 Standard Power-up Timing Power resources will be configured sequentially until the device reaches the power state. USBON . At this time internal power-on-reset signal PORZ will be released and USB PLL will start up. Once PLL is locked, the DIR output pin will be deasserted allowing TUSB1211 to be configured by the USB Link Controller via the ULPI interface. Note that by default TUSB1211 will be configured as a Host not providing VBUS as required by register map in ULPI specification Rev1.1. This is the case because OTG_CONTROL register bits DRVVBUS and DRVVBUSEXTERNAL bits are 0 by default, and DPPULLDOWN, DMPULLDOWN bits are 1 by default such that the 15 kΩ pulldown resistors at DP/DM pins are enabled by default. It is the responsibility of the link to enable external VBUS supply if required in Host mode, or to reconfigure the PHY if required in Device mode. • Hardware charger detection power-up When the chip is not selected (CS=0 or CS_N=1), but VBUS is present and CHRG_EN_N pin is at GND, and VBAT > VBAT_MNTR then TUSB1211 will power-up in Hardware Charger Detection Mode. Power resources will be configured sequentially until the device reaches the power state USBON . However since chip is not selected, internal power-on-reset signal PORZ will be not be released and USB PLL will not start up. Instead the device will enter USB Battery charger finite state machine (FSM) 14 Power Management Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TUSB1211 TUSB1211 www.ti.com SLLSE80 – MARCH 2011 .

Table 7-1. Interface Target Frequencies IO INTERFACE INTERFACE DESIGNATION High speed USB 7.1 Universal serial bus TARGET FREQUENCY 480 Mbits/s Full speed 12 Mbits/s Low speed 1.5 Mbits/s PHY Overview The PHY is the physical signaling layer of the USB 2.0. It essentially contains all the drivers and receivers required for physical data and protocol signaling on the DP and DM lines. The PHY interfaces to the USB controller through a standard 12-pin digital interface called UTMI+ low pin interface (ULPI). The transmitters and receivers inside the PHY are classified into two main classes. • The full-speed (FS) and low-speed (LS) transceivers. These are the legacy USB1.x transceivers. • The HS (HS) transceivers In order to bias the transistors and run the logic, the PHY also contains reference generation circuitry which consists of: • A PLL which does a frequency multiplication to achieve the 480-MHz low-jitter clock necessary for USB and also the clock required for the switched capacitor resistance block. • Internal biasing circuitry Built-in pullup and pulldown resistors are used as part of the protocol signaling. Apart from this, the PHY also contains circuitry which protects it from accidental short on the DP and DM lines to 5 V or GND. 16 USB Transceiver (PHY) Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TUSB1211 TUSB1211 www.ti.com 8 SLLSE80 – MARCH 2011 UART Transceiver By setting CARKITMODE bit in IFC_CTRL register TUSB1211 will enter UART mode.

This feature includes: • Battery charger detection sensing and control on DP/DM lines • ACA (Accessory Charger Adapter) detection and control on ID line The detection mechanism aims at distinguishing several types of power sources that can be connected on VBUS line: • Dedicated Charging Port • Standard Downstream Port • Charging Downstream Port Hardware includes: • a dedicated voltage referenced pullup on DP line • a dedicated current controlled pulldown on DM line • a detection comparator on DM line - a control/detection finite state machine (FSM) including timers • a charger detection output pin (CHRG_DET) for external charger control • detection comparators on ID line ID pin status detection (as defined per OTG v1.3 standard as well as ACA resistor types as described in BCS v1.1) and DP/DM Single-Ended receivers (as defined per USB v2.0 standard) are also used to determine the type of device plugged on USB connector.

Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
