 2004 - 2016 Microchip Technology Inc.

1.0

INTRODUCTION

The USB2601/USB2602 is an Integrated “combo” High-Speed USB hub and Flash Media Controller. The Flash media
controller permanently resides on Port 1 of the Integrated USB hub.

1.1

High-Speed Hub

The integrated Microchip Hub is fully compliant with the USB 2.0 Specification and will attach to a USB host as a Full-
Speed Hub or as a Full-/High-Speed Hub. The Hub supports Low-Speed, Full-Speed, and High-Speed (if operating as
a High-Speed Hub) downstream devices on all of the enabled downstream ports.

A dedicated Transaction Translator (TT) is available for each downstream facing port. This architecture ensures maxi-
mum USB throughput for each connected device when operating with mixed-speed peripherals. 

The Hub works with an external USB power distribution switch device to control V

BUS

 switching to downstream ports,

and to limit current and sense over-current conditions. 

All required resistors on the USB ports are integrated into the Hub. This includes all series termination resistors on D+
and D– pins and all required pull-down and pull-up resistors on D+ and D– pins. The over-current sense inputs for the
downstream facing ports have internal pull-up resistors.

Throughout this document the upstream facing port of the hub will be referred to as the upstream port, and the down-
stream facing ports will be called the downstream ports.

Three externally available ports are available for general USB device connectivity.

1.2

Flash Media Controller

The Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF and CF Ultra I/II)
in True IDE Mode only, SmartMedia (SM) and xD cards, Memory Stick (MS), Memory Stick DUO (MSDUO) and Memory
Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard (MMC) flash memory devices. It provides a single chip
solution for the most popular flash memory cards in the market.

The device consists of buffers, Fast 8051 microprocessor with expanded scratchpad, and program SRAM, and CF, MS,
SM and SD controllers. The SD controller supports both SD and MMC devices. SM controller supports both SM and xD
cards.

12K bytes of scratchpad SRAM and 768 Bytes of program SRAM are also provided.

Eleven GPIO pins are provided for indicators, external serial EEPROM for OEM ID and system configuration informa-
tion, and other special functions.

Internal power FETs are provided to directly supply power to the xD/SM, MMC/SD and MS/MSPro cards.

The internal ROM program is capable of implementing any combination of single or multi-LUN CF/SD/MMC/SM/MS
reader functions with individual card power control and activity indication. Microchip also provides licenses** for Win98
and Win2K drivers and setup utilities. Note: Please check with Microchip for precise features and capabilities for the
current ROM code release.

Note 1: RBIAS is connected to the Analog Ground plane VSS via a resistor.

2: When the internal 1.8V regulators are enabled, VDD18 (Pin 86) & VDD18PLL (Pin 124), MUST have a 10uf

+/- 20%, (equivalent series resistance (ESR) <0.1ohm) bypass capacitor to VSS. These capacitors must be

 2004 - 2016 Microchip Technology Inc.

1.0

INTRODUCTION

The USB2601/USB2602 is an Integrated “combo” High-Speed USB hub and Flash Media Controller. The Flash media
controller permanently resides on Port 1 of the Integrated USB hub.

1.1

High-Speed Hub

The integrated Microchip Hub is fully compliant with the USB 2.0 Specification and will attach to a USB host as a Full-
Speed Hub or as a Full-/High-Speed Hub. The Hub supports Low-Speed, Full-Speed, and High-Speed (if operating as
a High-Speed Hub) downstream devices on all of the enabled downstream ports.

A dedicated Transaction Translator (TT) is available for each downstream facing port. This architecture ensures maxi-
mum USB throughput for each connected device when operating with mixed-speed peripherals. 

The Hub works with an external USB power distribution switch device to control V

BUS

 switching to downstream ports,

and to limit current and sense over-current conditions. 

All required resistors on the USB ports are integrated into the Hub. This includes all series termination resistors on D+
and D– pins and all required pull-down and pull-up resistors on D+ and D– pins. The over-current sense inputs for the
downstream facing ports have internal pull-up resistors.

Throughout this document the upstream facing port of the hub will be referred to as the upstream port, and the down-
stream facing ports will be called the downstream ports.

Three externally available ports are available for general USB device connectivity.

1.2

Flash Media Controller

The Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF and CF Ultra I/II)
in True IDE Mode only, SmartMedia (SM) and xD cards, Memory Stick (MS), Memory Stick DUO (MSDUO) and Memory
Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard (MMC) flash memory devices. It provides a single chip
solution for the most popular flash memory cards in the market.

The device consists of buffers, Fast 8051 microprocessor with expanded scratchpad, and program SRAM, and CF, MS,
SM and SD controllers. The SD controller supports both SD and MMC devices. SM controller supports both SM and xD
cards.

12K bytes of scratchpad SRAM and 768 Bytes of program SRAM are also provided.

Eleven GPIO pins are provided for indicators, external serial EEPROM for OEM ID and system configuration informa-
tion, and other special functions.

Internal power FETs are provided to directly supply power to the xD/SM, MMC/SD and MS/MSPro cards.

The internal ROM program is capable of implementing any combination of single or multi-LUN CF/SD/MMC/SM/MS
reader functions with individual card power control and activity indication. Microchip also provides licenses** for Win98
and Win2K drivers and setup utilities. Note: Please check with Microchip for precise features and capabilities for the
current ROM code release.

 2004 - 2016 Microchip Technology Inc.

1.0

INTRODUCTION

The USB2601/USB2602 is an Integrated “combo” High-Speed USB hub and Flash Media Controller. The Flash media
controller permanently resides on Port 1 of the Integrated USB hub.

1.1

High-Speed Hub

The integrated Microchip Hub is fully compliant with the USB 2.0 Specification and will attach to a USB host as a Full-
Speed Hub or as a Full-/High-Speed Hub. The Hub supports Low-Speed, Full-Speed, and High-Speed (if operating as
a High-Speed Hub) downstream devices on all of the enabled downstream ports.

A dedicated Transaction Translator (TT) is available for each downstream facing port. This architecture ensures maxi-
mum USB throughput for each connected device when operating with mixed-speed peripherals. 

The Hub works with an external USB power distribution switch device to control V

BUS

 switching to downstream ports,

and to limit current and sense over-current conditions. 

All required resistors on the USB ports are integrated into the Hub. This includes all series termination resistors on D+
and D– pins and all required pull-down and pull-up resistors on D+ and D– pins. The over-current sense inputs for the
downstream facing ports have internal pull-up resistors.

Throughout this document the upstream facing port of the hub will be referred to as the upstream port, and the down-
stream facing ports will be called the downstream ports.

Three externally available ports are available for general USB device connectivity.

1.2

Flash Media Controller

The Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF and CF Ultra I/II)
in True IDE Mode only, SmartMedia (SM) and xD cards, Memory Stick (MS), Memory Stick DUO (MSDUO) and Memory
Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard (MMC) flash memory devices. It provides a single chip
solution for the most popular flash memory cards in the market.

The device consists of buffers, Fast 8051 microprocessor with expanded scratchpad, and program SRAM, and CF, MS,
SM and SD controllers. The SD controller supports both SD and MMC devices. SM controller supports both SM and xD
cards.

12K bytes of scratchpad SRAM and 768 Bytes of program SRAM are also provided.

Eleven GPIO pins are provided for indicators, external serial EEPROM for OEM ID and system configuration informa-
tion, and other special functions.

Internal power FETs are provided to directly supply power to the xD/SM, MMC/SD and MS/MSPro cards.

The internal ROM program is capable of implementing any combination of single or multi-LUN CF/SD/MMC/SM/MS
reader functions with individual card power control and activity indication. Microchip also provides licenses** for Win98
and Win2K drivers and setup utilities. Note: Please check with Microchip for precise features and capabilities for the
current ROM code release.

as close to the pins as possible.
