USB82513
1.1 OEM Selectable Features
A default configuration is available in the USB82513 following a reset. This configuration may be sufficient for some
applications. Strapping option pins make it possible to modify a limited sub-set of the configuration options.
The USB82513 may also be configured by an external EEPROM or a microcontroller. When using the microcontroller
interface, the hub appears as an SMBus slave device. If the hub is pin-strapped for external EEPROM configuration but
no external EEPROM is present, then a value of ‘0’ will be written to all configuration data bit fields (the hub will attach
to the host with all ‘0’ values).
The USB82513 supports several OEM selectable features:
• Optional OEM configuration via I2C EEPROM or via the industry standard SMBus interface from an external
SMBus host or microcontroller, see Table 7-1, "Hub Configuration Options" to configure the serial port interface
behavior via the CFG_SEL1 and CFG_SEL0 pins.
• Compound device support (port is permanently hardwired to a downstream USB peripheral device), on a port-by-
port basis, see "Register 07h: Configuration Data Byte 2", bit COMPOUND.
• Select Single-Transaction Translator (STT) or Multi-Transaction Translator (MTT), see "Register 06h: Configura-
tion Data Byte 1", bit MTT_ENABLE.
• Select over-current sensing and port power control on an individual (port-by-port) or ganged (all ports together)
basis to match the OEM’s choice of circuit board component selection, see "Register 06h: Configuration Data Byte
1", bits CURRENT_SNS and PORT_PWR.
• Customize vendor ID, product ID, and device ID, see "Register 00h: Vendor ID (LSB)", "Register 01h: Vendor ID
(MSB)", "Register 02h: Product ID (LSB)", "Register 03h: Product ID (MSB)", "Register 04h: Device ID (LSB)" and
"Register 05h: Device ID (MSB)".
• Easily configure as a 2 or 3-Port Hub in common PCB layout, see "Register 0Ah: Port Disable for Self-Powered
Operation" and "Register 0Bh: Port Disable for Bus-Powered Operation".
• PortMap: Flexible port mapping and disable sequence. Ports can be disabled/reordered in any sequence to sup-
port multiple platforms with a single design. The hub will automatically reorder the remaining ports to match the
host controller's numbering scheme, see "Register FBh: PortMap 12" and "Register FCh: PortMap 34".
• PortSwap: Programmable USB differential-pair pin location.
- Eases PCB layout by aligning USB signal lines directly to connectors, see "Register FAh: PortSwap".
• PhyBoost: Programmable USB signal drive strength. Recover USB signal integrity due to compromised system
environments using 4 levels of signal drive strength, see "Register F6h: Boost_Up" and "Register F8h: Boost_4:0".
• Configure the delay time for filtering the over-current sense inputs, see "Register 07h: Configuration Data Byte 2",
bit OC_TIMER.
• Configure the downstream port power-on time reported to the host, see "Register 10h: Power-On Time".
• Indicate the maximum current that the 3-port hub consumes from the USB upstream port, see "Register 0Eh: Hub
Controller Max Current for Self-Powered Operation" and "Register 0Fh: Hub Controller Max Current for Bus-Pow-
ered Operation".
• Indicate the maximum current required for the hub controller, see "Register 0Ch: Max Power for Self-Powered
Operation" and "Register 0Dh: Max Power for Bus-Powered Operation".
• Support custom string descriptor up to 31 characters in length for:
- Manufacturer string, see "Register 16h-53h: Manufacturer String".
- Product string, see "Register 54h-91h: Product String".
- Serial number string, see "Register 92h-CFh: Serial String".
• Pin selectable options for default configuration:
- Downstream ports as non-removable ports, see "Register 09h: Non-Removable Device".
- Downstream ports as disabled ports, see "Register 0Ah: Port Disable for Self-Powered Operation" and "Reg-
ister 0Bh: Port Disable for Bus-Powered Operation".

NON_REM1
NON_REM1: Non-removable port strap option.
If this strap is enabled by package and configuration settings (see
Table 7-1, "Hub Configuration Options"), this pin will be sampled (in
conjunction with SUSP_IND/LOCAL_PWR/NON_REM0) at RESET_N
negation to determine if ports [3:1] contain permanently attached (non-
removable) devices:
NON_REM[1:0] = ‘00’, All ports are removable,
NON_REM[1:0] = ‘01’, Port 1 is non-removable,

NON_REM[1:0] = ‘10’, Ports 1 & 2 are non-removable

Configuration Select_SEL0: The logic state of this multifunction pin is
internally latched on the rising edge of RESET_N (RESET_N negation)
and will determine the hub configuration method as described in
Table 7-1, "Hub Configuration Options".
