PIN DESCRIPTIONS
This section provides a detailed description of each signal. The signals are arranged in functional groups according to
their associated interface. The pin descriptions are applied when using the internal default firmware and can be refer-
enced in Section 7.0, "Configuration Options," on page 21. Please reference Section 1.1, "Acronyms," on page 5 for a
list of the acronyms used.
The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage
level. When “n” is not present in the signal name, the signal is asserted at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of
“active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of
whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inac-
tive.

When RESET_N is negated, the value on these
pins will be latched internally and these pins will
revert to MA[1:0] functionality; the internal pull-
downs will be disabled.

If the latched value is '1', the corresponding MA
pin is tri-stated when the chip is in power down
state.
If the latched value is '0', the corresponding MA
pin will function identically to MA[15:3] pins at all
times (other than during RESET_N assertion).

CONFIGURATION OPTIONS
Card Reader
The Microchip USB2250/50i/51/51i is fully compliant with the following flash media card reader specifications:
• Compact Flash 4.1
- CF UDMA Modes 0-4
- CF PIO Modes 0-6
• Secure Digital 2.0
- HS-SD and HC-SD
- TransFlash™ and reduced form factor media
• MultiMediaCard 4.2
- 1/4/8 bit MMC
• Memory Stick 1.43
• Memory Stick Pro Format 1.02
• Memory Stick Pro-HG Duo Format 1.01
- Memory Stick, MS Duo, HS-MS, MS Pro-HG, MS Pro
• Memory Stick Duo 1.10
• Smart Media 1.3
• xD-Picture Card 1.2
7.1.1
VBUS DETECT
According to Section 7.2.1 of the USB 2.0 Specification, a device cannot provide power to its D+ or D- pull-up resistors
unless the upstream port’s VBUS is in the asserted (powered) state. The VBUS_DET pin on the device monitors the
state of the upstream VBUS signal and will not pull-up the D+ resistor if VBUS is not active. If VBUS goes from an active
to an inactive state (not powered), the device will remove power from the D+ pull-up resistor within 10 seconds.
7.2
System Configurations
7.2.1
EEPROM
The USB2250/50i/51/51i can be configured via a 2-wire (I2C) EEPROM (512x8) flash device containing the options for
the USB2250/50i/51/51i. If an external configuration device does not exist the internal default values will be used. If one
of the external devices is used for configuration, the OEM can update the values through the USB interface. The device
will then “attach” to the upstream USB host.
The USBDM tool set is available in the USB225x Card Reader software release package. To download the software
package from Microchip's website, please visit:
http://www.microchip.com/SWLibraryWeb/producttc.aspx?product=OBJ%20files%20for%20USB2250
to go to the OBJ Card Reader Software Download Agreement. Review the license, and if you agree, check the "I agree"
box and then select “Confirm”. You will then be able to download the USB225x Card reader combo release package zip
files containing the USBDM tool set. Please note that the following applies to the system values and descriptions when
used:
• N/A = Not applicable to this part
• Reserved = For internal use

Self- or Bus-Power: Selects between self- and bus-powered operation.
The hub is either self-powered (draws less than 2 mA) or bus-powered (limited
to 100 mA maximum power prior to being configured by the host controller).
When configured as a bus-powered device, the Microchip device consumes
less than 100 mA of current prior to being configured. After configuration, the
bus-powered Microchip device (along with all associated device circuitry, any
embedded devices if part of a compound device, and 100 mA per externally
available downstream port) must consume no more than 500 mA of current.
The current consumption is system dependent, and the OEM must ensure that
the USB 2.0 Specification is not violated.
When configured as a self-powered device, <1 mA of current is consumed and
all ports are available, with each port being capable of sourcing 500 mA of
current.

A0H-A7H: DEVICE POWER CONFIGURATION
The USB2250/50i/51/51i has four internal FETs which can be utilized for card power. This section describes the default
internal configuration. The settings are stored in NVSTORE and provide the following features:
1. A card can be powered by an external FET or by an internal FET.
2. The power limit can be set to 100 mA or 200 mA (Default) for the internal FET.
Each media uses two bytes to store its device power configuration. Bit 3 selects between internal or external card power
FET options. For internal FET card power control, bits 0 through 2 are used to set the power limit. The “Device Power
Configuration” bits are ignored unless the “Enable Device Power Configuration” bit is set. See Section 7.2.3.19, "9Ch-

DYN_NUM_LUN
These bytes are used to specify the number of LUNs the device exposes to
the host. These bytes are also used for icon sharing by assigning more than
one LUN to a single icon. This is used in applications where the device utilizes
a combo socket and the OEM wishes to have only a single icon displayed for
one or more interfaces.
If this field is set to "FF", the program assumes that you are using the default
value and icons will be configured per the default configuration.
7.2.5.8
D4h-D7h: Device to LUN Mapping
Byte
Name
Description
3:0
DEV_LUN_MAP
These registers map a device controller (SD/MMC, SM, and MS) to a Logical
Unit Number (LUN). The device reports the mapped LUNs to the USB host in
the USB descriptor during enumeration. The icon installer associates custom
icons with the LUNs specified in these fields.
Setting a register to "FF" indicates that the device is not mapped. Setting all
of the DEV_LUN_MAP registers for all devices to "FF" forces the use of the
default mapping configuration. Not all configurations are valid. Valid
configurations depend on the hardware, packaging, and OEM board layout.
The number of unique LUNs mapped must match the value in the Section
7.2.5.7, "D3h: Dynamic Number of LUNs," on page 29.

Default Configuration Option
The Microchip device can be configured via its internal default configuration. Please see Section 7.2.2, "EEPROM Data
Descriptor" for specific details on how to enable default configuration. Please refer to Table 7-1 for the internal default
values that are loaded when this option is selected.
7.3.1
EXTERNAL HARDWARE NRESET
A valid hardware reset is defined as assertion of nRESET for a minimum of 1 s after all power supplies are within oper-
ating range. While reset is asserted, the device (and its associated external circuitry) consumes less than 500 A of
current.
Assertion of nRESET (external pin) causes the following:
1. The PHY is disabled and the differential pair will be in a high-impedance state.
2. All transactions immediately terminate; no states are saved.
3. All internal registers return to the default state.
4. The external crystal oscillator is halted.
5. The PLL is halted.
6. The processor is reset.
7. All media interfaces are reset.

C0 is usually included (subtracted by the crystal manufacturer) in the specification for CL and should
be set to ‘0’ for use in the calculation of the capacitance formulas in Figure 8-2, "Capacitance
Formulas". However, the OEM PCB itself may present a parasitic capacitance between XTAL1 and
XTAL2. For an accurate calculation of C1 and C2, take the parasitic capacitance between traces
XTAL1 and XTAL2 into account.
Each of these capacitance values is typically approximately 18 pF.

Note 9-2
When powering this device from laboratory or system power supplies, it is important that the absolute
maximum ratings not be exceeded or device failure can result. Some power supplies exhibit voltage
spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on
the AC power line may appear on the DC output. When this possibility exists, it is suggested that a
clamp circuit be used.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
