USB84604

1.0

GENERAL DESCRIPTION

The Microchip USB84604 is a low-power, OEM configurable, MTT (Multi-Transaction Translator) USB 2.0 controller hub

with 4 downstream ports and advanced features for embedded USB applications. The USB84604 is fully compliant with

the USB 2.0 Specification

[

2],

USB 2.0 Link Power Management Addendum, High-Speed Inter-Chip (HSIC) USB Elec-

trical Specification Revision 1.0

[

4],

and will attach to an upstream port as a Full-Speed hub or as a Full-/Hi-Speed hub.

The 4-port hub supports Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed hub) downstream devices

on all of the enabled downstream (non-HSIC) ports. HSIC ports support only Hi-Speed operation.

The USB84604 has been specifically optimized for embedded systems where high performance and minimal BOM

costs are critical design requirements. Standby mode power has been minimized and reference clock inputs can be

aligned to the customer’s specific application. Flexible power rail options ease integration into energy efficient designs

by allowing the USB84604 to be powered in a single-source (VBUS, VBAT, 3.3 V) or a dual-source (VBAT + 1.8, 3.3 V

+ 1.8) configuration. Additionally, all required resistors on the USB ports are integrated into the hub, including all series

termination and pull-up/pull-down resistors on the D+ and D- pins.

The USB84604 supports downstream battery charging. The USB84604 includes embedded USB device/slave function-

ality which is dedicated for use as a USB to I

C/SPI interface, allowing external circuits or devices to be monitored, con-

trolled, or configured via the USB interface. Additionally, the USB84604 includes many powerful and unique features

such as:

FlexConnect,

which provides flexible connectivity options. The USB84604’s downstream port 1 can be swapped with

the upstream port, allowing master capable devices to control other devices on the hub.

MultiTRAK

Technology,

which utilizes a dedicated Transaction Translator (TT) per port to maintain consistent full-

speed data throughput regardless of the number of active downstream connections. MultiTRAK

outperforms conven-

tional USB 2.0 hubs with a single TT in USB full-speed data transfers.

PortMap,

which provides flexible port mapping and disable sequences. The downstream ports of a USB84604 hub can

be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any port that is

disabled, the USB84604 Hub Controller automatically reorders the remaining ports to match the USB host controller’s

port numbering scheme.

PortSwap,

which adds per-port programmability to USB differential-pair pin locations. PortSwap allows direct alignment

of USB signals (D+/D-) to connectors to avoid uneven trace length or crossing of the USB differential signals on the

PCB.

PHYBoost,

which provides programmable levels of Hi-Speed USB signal drive

strength in the downstream port transceivers. PHYBoost can restore USB signal

integrity in a compromised system environment. The graphic on the right shows an

example of Hi-Speed USB eye diagrams before and after PHYBoost signal integrity

restoration.

VariSense,

which controls the USB receiver sensitivity enabling programmable lev-

els of USB signal receive sensitivity. This capability allows operation in a sub-optimal

system environment, such as when a captive USB cable is used.

The USB84604 is available for the automotive temperature range (-40 ºC to 85 ºC).

Available firmware revisions are shown in the

Product Identification System on page 60:

‘001080’ and ‘001070’. The

‘001080’ version enables the internal Hub Feature Controller, while the ‘001070’ version disables it. There are no addi-

tional differences between these two versions.
