1.1
Supported Operating Systems
Windows XP (SP2 and later), Windows Vista, Windows
7, Windows 8, Windows 8.1 and Windows 10 operating
systems are supported.
1.1.1
ENUMERATION
The MCP2200 will enumerate as a USB device after
Power-on Reset (POR). The device enumerates as
both a Human Interface Device (HID) for I/O control,
and a Virtual Com Port (VCP).
1.1.1.1
Human Interface Device (HID)
The MCP2200 enumerates as an HID, so the device
can be configured and the I/O can be controlled. A DLL
that facilitates I/O control through a custom interface is
supplied by Microchip.
1.1.1.2
Virtual Com Port (VCP)
The VCP enumeration implements the USB-to-UART
data translation.
1.2
Control Module
The control module is the heart of the MCP2200. All
other modules are tied together and controlled via the
control module. The control module manages the data
transfers between the USB and the UART, as well as
the command requests generated by the USB host
controller and the commands for controlling the
function of the UART and I/O.
1.2.1
SERIAL INTERFACE
The control module interfaces to the UART and USB
modules.
1.2.2
INITIAL CONFIGURATION
The default UART configuration is 19200, 8, N, 1. The
default start-up baud rate can be changed using the
Microchip-supplied configuration PC tool.
Alternatively, a custom configuration tool can be
created using the Microchip-supplied DLL to set the
baud rate as well as other parameters. See Section 2.0
“Configuration” for details.
TABLE 1-2:
UART CONFIGURATIONS
Parameter
UART Interface
The MCP2200 UART interface consists of the Tx and
Rx data signals and the RTS/CTS flow control pins.
The UART is configurable for several baud rates. The
available baud rates are listed in Table 1-3.

1.3.2
GET/SET LINE CODING
The GET_LINE_CODING and SET_LINE_CODING
commands are used to read and set the UART
parameters while in operation. For example,
HyperTerminal sends the SET_LINE_COMMAND when
connecting to the port. The MCP2200 responds by
setting the baud rate only. The other parameters (data
bits, parity, stop bits) remain unchanged.
1.3.2.1
Rounding Errors
The primary baud rate setting (with the rounding errors)
is shown in Table 1-3. If baud rates other than the ones
shown in the table are used, the error percentage can
be calculated using Equation 1-1 to find the actual
baud rate.
TABLE 1-3:
INTERFACING TO THE DEVICE
The MCP2200 can be accessed for reading and writing
via USB host commands. The device cannot be
accessed and controlled via the UART interface.

1.3.4
HARDWARE FLOW CONTROL
1.4
USB Protocol Controller
The USB controller in the MCP2200 is full-speed USB
2.0 compliant.
• Composite device (CDC + HID):
- CDC: USB-to-UART communications
- HID: I/O control, EEPROM access and initial
configuration
• 128-byte buffer to handle data throughput at any
UART baud rate:
- 64-byte transmit
- 64-byte receive
• Fully configurable VID and PID assignments and
descriptors (stored on-chip)
• Bus-powered or self-powered
Hardware flow control uses the RTS and CTS pins as
a handshake between two devices. The RTS pin of
one device is typically connected to the CTS of the
other device.
1.4.1
RTS is an active-low output that notifies the other
device when it is ready to receive data by driving the pin
low. The MCP2200 trip point for deasserting RTS (high)
is 63 characters. This is one character short of “buffer
full”.
1.4.2
CTS is an active-low input that notifies the MCP2200
when it is ready to send data. The MCP2200 will check
CTS just before loading and sending UART data. If the
pin is asserted during a transfer, the transfer will
continue. Refer to Figure 1-1.
The MCP2200 exits Suspend mode when any of the
following events occur:

MCP2200
During configuration, the supplied PC interface stores
the descriptors in the MCP2200.
Flow Control Disabled
The buffer pointer does not increment (or reset to
zero) if the buffer is full. Therefore, if hardware flow
control is not enabled and an overflow occurs (i.e.,
65 unprocessed characters received), the new data
overwrites the last position in the buffer.
 2011-2015 Microchip Technology Inc.
SUSPEND AND RESUME
The USB Suspend and Resume signals are supported
for power management of the MCP2200. The device
enters Suspend mode when “suspend signaling” is
detected on the bus.

1.5
USB Transceiver
The MCP2200 has a built-in, full-speed USB 2.0
transceiver internally connected to the USB module.
The USB transceiver obtains power from the VUSB pin,
which is internally connected to the 3.3V regulator. The
best electrical signal quality is obtained when VUSB is
locally bypassed with a high-quality ceramic capacitor.
1.5.1
INTERNAL PULL-UP RESISTORS
The MCP2200 devices have built-in pull-up resistors
designed to meet the requirements for full-speed USB.

• 3.3V Self-Powered
DS20002228C-page 5
MCP2200
1.5.2.1
Internal Power Supply Details
MCP2200 offers various options for power supply. To
meet the required USB signaling levels, the MCP2200
device incorporates an internal LDO used solely by the
USB transceiver in order to present the correct D+/Dvoltage levels.
Figure 1-2 shows the internal connections of the USB
transceiver LDO in relation to the VDD power supply
rail. The output of the USB transceiver LDO is tied to
the VUSB line. A capacitor connected to the VUSB pin is
required if the USB transceiver LDO provides the 3.3V
supply to the transceiver.

MCP2200 INTERNAL
POWER SUPPLY DETAILS
1.5.2.2
USB Bus-Powered (5V)
In Bus Power Only mode, all power for the application
is drawn from the USB (Figure 1-3). This is effectively
the simplest power method for the device.

USB
Transceiver
In order to meet the inrush current requirements of the
USB 2.0 specifications, the total effective capacitance
appearing across VBUS and ground must be no more
than 10 µF. If it is not more than 10 µF, some kind of
inrush current limiting is required. For more details on
inrush current limiting, consider the latest version of the
“Universal Serial Bus Specification”.
According to the USB 2.0 specification, all USB devices
must also support a low-power Suspend mode. In the
USB Suspend mode, devices must consume no more
than 500 µA (or 2.5 mA for high-powered devices that
are remote wake-up capable) from the 5V VBUS line of
the USB cable.
The host signals the USB device to enter Suspend
mode by stopping all USB traffic to that device for more
than 3 ms.
The provided VDD voltage has a direct influence on the
voltage levels present on the GPIO pins (Rx/Tx and
RTS/CTS). When VDD is 5V, all of these pins will have
a logical ‘1’ around 5V with the variations specified in
Section 3.1 “DC Characteristics”.
For applications that require a 3.3V logical ‘1’ level,
VDD must be connected to a power supply providing
3.3V voltage. In this case, the internal USB transceiver
LDO cannot provide the required 3.3V of power. It is
necessary to also connect the VUSB pin to the 3.3V
power supply rail. This way, the USB transceiver is
powered-up directly from the 3.3V power supply.
DS20002228C-page 6
The USB bus provides a 5V voltage. However, the USB
transceiver requires 3.3V for the signaling (on the D+
and D- lines).
During USB Suspend mode, the D+ or D- pull-up
resistor must remain active, which will consume some
of the allowed suspended current budget (500 µA/
2.5 mA). The VUSB pin is required to have an external
bypass capacitor. It is recommended that the capacitor
be a ceramic capacitor between 0.22 µF. and 0.47 µF.
Figure 1-4 shows a circuit where MCP2200’s internal
LDO is used to provide 3.3V to the USB transceiver.
The voltage on the VDD affects the voltage levels onto
the GPIO pins (Rx/Tx and RTS/CTS). With VDD at 5V,
these pins will have a logic ‘1’ of 5V with the variations
specified in Section 3.1 “DC Characteristics”.

3.3V Self-Powered
Typically, many embedded applications are using 3.3V
power supplies. When such an option is available in the
target system, MCP2200 can be powered up from the
existing 3.3V power supply rail. The typical connections
for the MCP2200 are shown in Figure 1-5.
In this example, the MCP2200 has both VDD and VUSB
lines tied to the 3.3V rail. These tied connections
disable the internal USB transceiver LDO of the
MCP2200 to regulate the power supply on VUSB pin.
Another consequence is that the ‘1’ logical level on the
GPIO pins will be at the 3.3V level, in accordance with
the variations specified in Section 3.1 “DC
Characteristics”.

GPIO Module
The GPIO Module is a standard 8-bit I/O port.
1.6.1
CONFIGURABLE PIN FUNCTIONS
The pins can be configured as:
• GPIO – individually configurable general purpose
input or output
• SSPND – USB Suspend state
• USBCFG – indicates USB configuration status
• RxLED – indicates USB receive traffic
• TxLED – indicates USB transmit traffic
1.6.1.1
SSPND Pin Function
The SSPND pin (if enabled) reflects the USB state
(Suspend/Resume). The pin is active-low when the
Suspend state has been issued by the USB host.
Likewise, the pin drives ‘high’ after the Resume state is
achieved.
This pin allows the application to go into low power
mode when USB communication is suspended, and
switches to a full active state when USB activity is
resumed.
1.6.1.2
USBCFG Pin Function
The USBCFG pin (if enabled) starts out ‘low’ during
power-up or after Reset, and goes ‘high’ after the
device successfully configures to the USB. The pin will
go ‘low’ when in Suspend mode and ‘high’ when the
USB resumes.

DS20002228C-page 7
MCP2200
1.6.1.3
RxLED Pin Function (IN Message)
The ‘Rx’ in the pin name is in respect to the USB host.
The RxLED pin is an indicator for USB ‘IN’ messages.
This pin will either pulse low for a period of time
(configurable for ~100 ms or ~200 ms), or toggle to the
opposite state for every message received
(IN message) by the USB host. This allows the
application to count messages or provide a visual
indication of USB traffic.
1.6.1.4
TxLED Pin Function (OUT Message)
The ‘Tx’ in the pin name is in respect to the USB host.
The TxLED pin is an indicator for USB ‘OUT’
messages.
When the device starts normal operation (i.e., exits the
Reset condition), device operating parameters
(voltage, frequency, temperature, etc.) must be met to
ensure operation. If these conditions are not achieved,
the device must be held in Reset until the operating
conditions are met.
1.9
Oscillator
The input clock must be 12 MHz to provide the proper
frequency for the USB module.
USB full speed is defined as 12 Mb/s. The clock input
accuracy is ±0.25% (2,500 ppm maximum).
FIGURE 1-6:
This pin will either pulse low for a period of time
(configurable for ~100 ms or ~200 ms), or toggle to the
opposite state for every message transmitted (OUT
message) by the USB host. This allows the application
to count messages or provide a visual indication of
USB traffic.

The EEPROM module is a 256-byte array of nonvolatile memory. The memory locations are accessed for
read/write operations via USB host commands. Refer
to Section 2.0 “Configuration” for details on accessing
the EEPROM. The memory cells for data EEPROM are
rated to endure thousands of erase/write cycles, up to
100K for EEPROM.

2 M to 10 M..
1.8
1.8.1
RESET/POR
RESET PIN
The RST pin provides a method for triggering an
external Reset of the device. A Reset is generated by
holding the pin low. These devices have a noise filter in
the Reset path which detects and ignores small pulses.

OSC1
A POR pulse is generated on-chip whenever VDD rises
above a certain threshold. This allows the device to
start in the initialized state when VDD is adequate for
operation.
To take advantage of the POR circuitry, tie the RST pin
through a resistor (1 kΩ to 10 kΩ) to VDD. This will
eliminate external RC components usually needed to
create a POR delay.

bool SimpleIOClass::WritePort(unsigned int portValue)
Summary:
Writes a value to the GPIO port.
Description:
Writes the GPIO port. This provides a means to write all pins simultaneously, instead of one-by-one.
Precondition:
Must be previously configured as an output via a ConfigureIO call. VID and PID must be previously
set via a call to InitMCP2200(VID, PID).
Parameters:
portValue - byte value to set on the port.
Returns:
This function returns True if the transmission is successful and returns False if the transmission fails.
Remarks:
None.
EXAMPLE 2-25:
if (SimpleIOClass::WritePort (0x5A))
{
lblStatusBar->Text = “Success”;
}
else
lblStatusBar->Text = “Invalid command ” +

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.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
