DEVICE OPERATION
The MCP2150 is a cost effective, low pin count (18-
pin), easy to use device for implementing IrDA stan-
dard wireless connectivity. The MCP2150 provides
support for the IrDA standard protocol “stack” plus bit
encoding/decoding. The Serial interface and IR baud
rates are independantly selectable.
2.1
Power Up
Any time the device is powered up (parameter D003),
the Power Up Timer delay (parameter 33) occurs, fol-
lowed by an Oscillator Start-up Timer (OST) delay
(parameter 32). Once these delays complete, commu-
nication with the device may be initiated. This commu-
nication is from both the infrared transceiver’s side as
well as the controller’s UART interface.
2.2
Device Reset
The MCP2150 is forced into the reset state when the
RESET pin is in the low state. Once the RESET pin is
brought to a high state, the Device Reset sequence
occurs. Once the sequence completes, functional
operation begins.
2.3
Clock Source
The MCP2150 requires a clock source to operate. The
frequency of this clock is 11.0592 MHz (electrical spec-
ification parameter 1A). This clock can be supplied by
either a crystal/resonator or as an external clock input.
2.3.1
CRYSTAL OSCILLATOR / CERAMIC
RESONATORS
A crystal or ceramic resonator can be connected to the
OSC1 and OSC2 pins to establish oscillation
(Figure 2-1). The MCP2150 oscillator design requires
the use of a parallel cut crystal. Use of a series cut crys-
tal may give a frequency outside of the crystal
manufacturers specifications.

EXTERNAL CLOCK IN
For applications where a clock is already available
elsewhere, users may directly drive the MCP2150 pro-
vided that this external clock source meets the AC/DC
timing requirements listed in Section 4.3. Figure 2-2
shows how an external clock circuit should be
configured.

Higher capacitance increases the stability of the oscil-
lator but also increases the start-up time. These val-
ues are for design guidance only. Since each
resonator has its own characteristics, the user should
consult the resonator manufacturer for appropriate
values of external components.

Higher capacitance increases the stability of the oscil-

ues are for design guidance only. RS may be required
to avoid overdriving crystals with low drive level spec-
ification.
