—
P
Ground reference for logic and I/O pins.
EN

7
I
TTL
Device enable.
1
= Device is enabled.
0
= Device is disabled (low power). MCP2150 only monitors
this pin when in the NDM state.
TX

I
TTL
Asynchronous receive; from Host Controller UART.
RX

O
—
Asynchronous transmit; to Host Controller UART.
RI
9
10
—
Ring Indicator. The value on this pin is driven high.
DSR
10
11
O
—
Data Set Ready. Indicates that the MCP2150 has completed
reset.
1
= MCP2150 is initialized.
0
= MCP2150 is not initialized.
DTR
11
12
I
TTL
Data Terminal Ready. The value of this pin is ignored once
the MCP2150 is initialized. It is recommended that this pin be
connected so that the voltage level is either VSS or VCC. At
device power up, this signal is used with the RTS signal to
enter device ID programming.
1
= Enter Device ID programming mode (if RTS is cleared).
0
= Do not enter Device ID programming mode.
CTS
12
13
O
—
Clear to Send. Indicates that the MCP2150 is ready to
receive data from the Host Controller.
1
= Host Controller should not send data.
0
= Host Controller may send data.
RTS
13
14
I
TTL
Request to Send. Indicates that a Host Controller is ready to
receive data from the MCP2150. The MCP2150 prepares to
send data, if available.
1
= Host Controller not ready to receive data.
0
= Host Controller ready to receive data.
At device power up, this signal is used with the DTR signal to
enter device ID programming.
1
= Do not enter Device ID programming mode.
0
= Enter Device ID programming mode (if DTR is set).
VDD
14
15, 16
—
P
Positive supply for logic and I/O pins.
OSC2
15

O
—
Oscillator crystal output.
OSC1/CLKIN
16
18
I
CMOS Oscillator crystal input/external clock source input.
CD
17
19
O
—
Carrier Detect. Indicates that the MCP2150 has established a
valid link with a Primary Device.
1
= An IR link has not been established (No IR Link).
0
= An IR link has been established (IR Link).
BAUD1

I
ST
BAUD1:BAUD0 specify the baud rate of the device.
