1.1
Supported Operating Systems
Microsoft Windows XP(SP2 and
operating systems are supported.
1.1.1
later)/Vista/7
ENUMERATION
The MCP2200 will enumerate as a USB device after
POR. The device enumerates as both a Human
Interface Device (HID) for I/O control, and a VCP.
1.1.1.1
HID
The MCP2200 enumerates as a HID so the device can
be configured and the I/O can be controlled. A DLL is
supplied by Microchip that allows I/O control using a
custom interface.
1.1.1.2
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
command requests generated by the USB host
controller, and 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
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
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 data formats and baud rates are listed in
Table 1-3.
1.3.1
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. The primary
baud rates are shown in Table 1-3.
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.
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)
are 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.

1.3.3
CUSTOM BAUD RATES
Custom baud rates are configured by sending the
SET_LINE_CODING USB command, or by using the
DLL. See Section 2.0 “Configuration” for more
information.

MCP2200
1.3.4
HARDWARE FLOW CONTROL
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.
RTS is an active low output which notifies the other
device when it can receive data by driving the pin low.
The MCP2200 trip point for de-asserting RTS (high) is
63 characters. This is one character short of “buffer
full”.
CTS is an active low input which is used to notify the
MCP2200 when it can 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.
1.3.4.1
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.

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
1.4.1
DESCRIPTORS
The descriptors are stored in the MCP2200 during
configuration using the supplied PC interface.
1.4.2
SUSPEND AND RESUME
The USB Suspend and Resume signals are supported
for power management of the MCP2200. The device
will enter Suspend mode when suspend signaling is
detected on the bus.
The MCP2200 exits the Suspend mode when any of
the following occur:
1.
2.
3.

Resume signaling is detected or generated
A USB Reset signal is detected
A device Reset occurs
DS22228A-page 5
MCP2200
1.5
USB Transceiver
1.6
The MCP2200 has a built-in, USB 2.0, full-speed
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.
1.5.1.1
Bus Power Only
In Bus Power Only mode, all power for the application
is drawn from the USB (Figure 1-2). This is effectively
the simplest power method for the device.
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 not, some kind of inrush limiting is
required. For more details, see Section 7.2.4 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.
During USB Suspend mode, the D+ or D- pull-up
resistor must remain active, which will consume some
of the allowed suspend current budget (500 µA/
2.5 mA).

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.
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.
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.

EEPROM Module
1.9
Oscillator
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 input clock must be 12 MHz to provide the proper
frequency for the USB module.
The host should wait for the write cycle to complete and
then verify the write by reading the byte(s).

accuracy is ±0.25% (2,500 ppm maximum).
QUARTZ CRYSTAL
OPERATION
RESET/POR
MCP2200
OSC1
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.
1.8.2
POR
A Power-on Reset 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 kOhm to 10 kOhm) to VDD. This
will eliminate external RC components usually needed
to create a Power-on Reset delay.
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.

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.
