The MC13192 is a short range, low power, 2.4 GHz
Industrial, Scientific, and Medical (ISM) band
transceivers. The MC13192 contains a complete
802.15.4 physical layer (PHY) modem designed for the
IEEE 802.15.4 Standard which supports peer-to-peer,
star, and mesh networking.
®
The MC13192 includes the 802.15.4 PHY/MAC for use
with the HCS08 Family of MCUs. The MC13192 can be
used with Freescale’s IEEE 802.15.4 MAC and
BeeStack, which is Freescale’s ZigBee 2006 compliant
protocol stack.
When combined with an appropriate microcontroller
(MCU), the MC13192 provide a cost-effective solution
for short-range data links and networks. Interface with
the MCU is accomplished using a four wire serial
peripheral interface (SPI) connection and an interrupt
request output which allows for the use of a variety of
processors. The software and processor can be scaled to
fit applications ranging from simple point-to-point
systems, through complete ZigBee™ networking.
Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its
products.

Figure 2 shows the basic system block diagram for the MC13192 in an application. Interface with the
transceiver is accomplished through a 4-wire SPI port and interrupt request line. The media access control
(MAC), drivers, and network and application software (as required) reside on the host processor. The host
can vary from a simple 8-bit device up to a sophisticated 32-bit processor depending on application
requirements.

Data Transfer Modes
4 Data Transfer Modes
The MC13192 has two data transfer modes:
1. Packet Mode — Data is buffered in on-chip RAM
2. Streaming Mode — Data is processed word-by-word
The Freescale 802.15.4 MAC software only supports the streaming mode of data transfer. For proprietary
applications, packet mode can be used to conserve MCU resources.
4.1
Packet Structure
Figure 3 shows the packet structure of the MC13192. Payloads of up to 125 bytes are supported. The
MC13192 adds a four-byte preamble, a one-byte Start of Frame Delimiter (SFD), and a one-byte Frame
Length Indicator (FLI) before the data. A two-byte Frame Check Sequence (FCS) is calculated and
appended to the end of the data.

Receive Path Description
In the receive signal path, the RF input is converted to low IF In-phase and Quadrature (I & Q) signals
through two down-conversion stages. A Clear Channel Assessment (CCA) can be performed based upon
the baseband energy integrated over a specific time interval. The digital back end performs Differential
Chip Detection (DCD), the correlator “de-spreads” the Direct Sequence Spread Spectrum (DSSS) Offset
QPSK (O-QPSK) signal, determines the symbols and packets, and detects the data.
The preamble, SFD, and FLI are parsed and used to detect the payload data and FCS which are stored in
RAM. A two-byte FCS is calculated on the received data and compared to the FCS value appended to the
transmitted data, which generates a Cyclical Redundancy Check (CRC) result. Link Quality is measured
over a 64 µs period after the packet preamble and stored in RAM.
If the MC13192 is in packet mode, the data is processed as an entire packet. The MCU is notified that an
entire packet has been received via an interrupt.
If the MC13192 is in streaming mode, the MCU is notified by an interrupt on a word-by-word basis.
Figure 4 shows CCA reported power level versus input power. Note that CCA reported power saturates at
about -57 dBm input power which is well above 802.15.4 Standard requirements.

Transmit Path Description
For the transmit path, the TX data that was previously stored in RAM is retrieved (packet mode) or the TX
data is clocked in via the SPI (stream mode), formed into packets per the 802.15.4 PHY, spread, and then
up-converted to the transmit frequency.
If the MC13192 is in packet mode, data is processed as an entire packet. The data is first loaded into the
TX buffer. The MCU then requests that the MC13192 transmit the data. The MCU is notified via an
interrupt when the whole packet has successfully been transmitted.
In streaming mode, the data is fed to the MC13192 on a word-by-word basis with an interrupt serving as
a notification that the MC13192 is ready for more data. This continues until the whole packet is
transmitted.

6.1
MC13192 Operational Modes
The MC13192 has a number of operational modes that allow for low-current operation. Transition from
the Off to Idle mode occurs when RST is negated. Once in Idle, the SPI is active and is used to control the
IC. Transition to Hibernate and Doze modes is enabled via the SPI. These modes are summarized, along
with the transition times, in Table 7. Current drain in the various modes is listed in Table 3, DC Electrical
Characteristics.

Serial Peripheral Interface (SPI)
The host microcontroller directs the MC13192, checks its status, and reads/writes data to the device
through the 4-wire SPI port. The transceiver operates as a SPI slave device only. A transaction between
the host and the MC13192 occurs as multiple 8-bit bursts on the SPI. The SPI signals are:
1. Chip Enable (CE) - A transaction on the SPI port is framed by the active low CE input signal. A
transaction is a minimum of 3 SPI bursts and can extend to a greater number of bursts.
2. SPI Clock (SPICLK) - The host drives the SPICLK input to the MC13192. Data is clocked into the
master or slave on the leading (rising) edge of the return-to-zero SPICLK and data out changes
state on the trailing (falling) edge of SPICLK.
NOTE
For Freescale microcontrollers, the SPI clock format is the clock phase
control bit CPHA = 0 and the clock polarity control bit CPOL = 0.
3. Master Out/Slave In (MOSI) - Incoming data from the host is presented on the MOSI input.
4. Master In/Slave Out (MISO) - The MC13192 presents data to the master on the MISO output.
A typical interconnection to a microcontroller is shown in Figure 7.

Although the SPI port is fully static, internal memory, timer and interrupt arbiters require an internal clock

core
registers and memory.
6.2.1
SPI Burst Operation
The SPI port of an MCU transfers data in bursts of 8 bits with most significant bit (MSB) first. The master
(MCU) can send a byte to the slave (transceiver) on the MOSI line and the slave can send a byte to the
master on the MISO line. Although an MC13192 transaction is three or more SPI bursts long, the timing
of a single SPI burst is shown in Figure 8.

6.2.2
SPI Transaction Operation
Although the SPI port of an MCU transfers data in bursts of 8 bits, the MC13192 requires that a complete
SPI transaction be framed by CE, and there will be three (3) or more bursts per transaction. The assertion
of CE to low signals the start of a transaction. The first SPI burst is a write of an 8-bit header to the
transceiver (MOSI is valid) that defines a 6-bit address of the internal resource being accessed and
identifies the access as being a read or write operation. In this context, a write is data written to the
MC13192 and a read is data written to the SPI master. The following SPI bursts will be either the write
data (MOSI is valid) to the transceiver or read data from the transceiver (MISO is valid).
Although the SPI bus is capable of sending data simultaneously between master and slave, the MC13192
never uses this mode. The number of data bytes (payload) will be a minimum of 2 bytes and can extend to
a larger number depending on the type of access. After the final SPI burst, CE is negated to high to signal
the end of the transaction. Refer to the MC13192 Reference Manual, (MC13192RM) for more details on
SPI registers and transaction types.
An example SPI read transaction with a 2-byte payload is shown in Figure 9.

Applications Information
8 Applications Information
This section provides application specific information regarding crystal oscillator reference frequency, a
basic design example for interfacing the MC13192 to an MCU and recommended crystal usage.
8.1
Crystal Oscillator Reference Frequency
The 802.15.4 Standard requires that several frequency tolerances be kept within ± 40 ppm accuracy. This
means that a total offset up to 80 ppm between transmitter and receiver will still result in acceptable
performance. The MC13192 transceiver provides onboard crystal trim capacitors to assist in meeting this
performance.
The primary determining factor in meeting this specification is the tolerance of the crystal oscillator
reference frequency. A number of factors can contribute to this tolerance and a crystal specification will
quantify each of them:
1. The initial (or make) tolerance of the crystal resonant frequency itself.
2. The variation of the crystal resonant frequency with temperature.
3. The variation of the crystal resonant frequency with time, also commonly known as aging.
4. The variation of the crystal resonant frequency with load capacitance, also commonly known as
pulling. This is affected by:
a) The external load capacitor values - initial tolerance and variation with temperature.
b) The internal trim capacitor values - initial tolerance and variation with temperature.
c) Stray capacitance on the crystal pin nodes - including stray on-chip capacitance, stray package
capacitance and stray board capacitance; and its initial tolerance and variation with
temperature.
Freescale requires the use of a 16 MHz crystal with a <9 pF load capacitance. The MC13192 does not
contain a reference divider, so 16 MHz is the only frequency that can be used. A crystal requiring higher
load capacitance is prohibited because a higher load on the amplifier circuit may compromise its
performance. The crystal manufacturer defines the load capacitance as that total external capacitance seen
across the two terminals of the crystal. The oscillator amplifier configuration used in the MC13192
requires two balanced load capacitors from each terminal of the crystal to ground. As such, the capacitors
are seen to be in series by the crystal, so each must be <18 pF for proper loading.
In the reference schematic, the external load capacitors are shown as 6.8 pF each, used in conjunction with
a crystal that requires an 8 pF load capacitance. The default internal trim capacitor value (2.4 pF) and stray
capacitance total value (6.8 pF) sum up to 9.2 pF giving a total of 16 pF. The value for the stray capacitance
was determined empirically assuming the default internal trim capacitor value and for a specific board
layout. A different board layout may require a different external load capacitor value. The on-chip trim
capability may be used to determine the closest standard value by adjusting the trim value via the SPI and
observing the frequency at CLKO. Each internal trim load capacitor has a trim range of approximately
5 pF in 20 fF steps.
Initial tolerance for the internal trim capacitance is approximately ±15%.
MC13192 Technical Data, Rev. 3.3
Freescale Semiconductor
17
Applications Information
Since the MC13192 contains an on-chip reference frequency trim capability, it is possible to trim out
virtually all of the initial tolerance factors and put the frequency within 0.12 ppm on a board-by-board
basis.
A tolerance analysis budget may be created using all the previously stated factors. It is an engineering
judgment whether the worst case tolerance will assume that all factors will vary in the same direction or if
the various factors can be statistically rationalized using RSS (Root-Sum-Square) analysis. The aging
factor is usually specified in ppm/year and the product designer can determine how many years are to be
assumed for the product lifetime. Taking all of the factors into account, the product designer can determine
the needed specifications for the crystal and external load capacitors to meet the 802.15.4 Standard.
8.2
Design Example
Figure 11 shows a basic application schematic for interfacing the MC13192 with an MCU. Table 9 lists
the Bill of Materials (BOM).
The MC13192 has differential RF inputs and outputs that are well suited to balanced printed wire antenna
structures. Alternatively, as in the application circuit, a printed wire antenna, a chip antenna, or other
single-ended structures can be used with commercially available chip baluns or microstrip equivalents.
PAO+ and PAO- require a DC connection to VDDA (the analog regulator output) through AC blocking
elements. This is accomplished through the baluns in the referenced design.
The 16 MHz crystal should be mounted close to the MC13192 because the crystal trim default assumes
that the listed KDS Daishinku crystal (see Table 10) and the 6.8 pF load capacitors shown are used. If a
different crystal is used, it should have a specified load capacitance (stray capacitance, etc.) of
9 pF or less. Other crystals are listed in Section 8.3, “Crystal Requirements.
VDDA is an analog regulator output used to supply only the onboard PA (PAO+ and PAO-) and VDDLO1
and VDDLO2 pins. VDDA should not be used to power devices external to the transceiver chip. Bypassing
capacitors are critical and should be placed close to the device. Unused pins should be grounded as shown.
The SPI connections to the MCU include CE, MOSI, MISO, and SPICLK. The SPI can run at a frequency
of 8 MHz or less. Optionally, CLKO can provide a clock to the MCU. The CLKO frequency is
programmable via the SPI and has a default of 32.786+ kHz (16 MHz / 488). The ATTN line can be driven
by a GPIO from the MCU (as shown) or can also be controlled by a switch or other hardware. The latter
approach allows the MCU to be put into a sleep mode and then awakened by CLKO when the ATTN line
wakes up the MC13192. RXTXEN is used to initiate receive, transmit or CCA/ED sequences under MCU
control. RXTXEN must be controlled by an MCU GPIO with the connection shown. Device reset (RST)
is controlled through a connection to an MCU GPIO.
When the MC13192 is used in Stream Mode, as with 802.15.4 MAC/PHY software, the MC13192 GPIO1
functions as an “Out of Idle” indicator and GPIO2 functions as a “CRC Valid” / Clear Channel Assessment
(CCA) result indicator and are not available for general purpose use.

User must be sure manufacturer specifications apply to the desired package.
A wider frequency tolerance may acceptable if application uses trimming at production final test.
A wider frequency stability may be acceptable if application uses trimming at production final test.
A wider aging tolerance may be acceptable if application uses trimming at production final test.
Higher ESR may be acceptable with lower load capacitance.
Lower load capacitance can allow higher ESR and is better for low temperature operation in Doze mode.
8.4
Low Power Considerations
•
Program and use the modem IO pins properly for low power operation
— All unused modem GPIOx signals must be used one of 2 ways:
– If the Off mode is to be used as a long term low power mode, unused GPIO should be tied
to ground. The default GPIO mode is an input and there will be no conflict.
– If only Hibernate and/or Doze modes are used as long term low power modes, the GPIO
should programmed as outputs in the low state.
— When modem GPIO are used as outputs:
– Pullup resistors should be provided (can be provided by the MCU IO pin if tied to the MCU)
if the modem Off condition is to be used as a long term low power mode.
– During Hibernate and/or Doze modes, the GPIO will retain its programmed output state.
— If the modem GPIO is used as an input, the GPIO should be driven by its source during all low
power modes or a pullup resistor should be provided.
— Digital outputs IRQ, MISO, and CLKO:
– MISO - is always an output. During Hibernate, Doze, and active modes, the default
condition is for the MISO output to go to tristate when CE is de-asserted, and this can cause
a problem with the MCU because one of its inputs can float. Program Control_B Register
07, Bit 11, miso_hiz_en = 0 so that MISO is driven low when CE is de-asserted. As a result,
MISO will not float when Doze or Hibernate Mode is enabled.
– IRQ - is an open drain output (OD) and should always have a pullup resistor (typically
provided by the MCU IO). IRQ acts as the interrupt request output.
NOTE
It is good practice to have the IRQ interrupt input to the MCU disabled
during the hardware reset to the modem. After releasing the modem
hardware reset, the interrupt request input to the MCU can then be enabled
to await the IRQ that signifies the modem is ready and in Idle mode; this can
prevent a possible extraneous false interrupt request.
– CLKO - is always an output. During Hibernate CLKO retains its output state, but does not
toggle. During Doze, CLKO may toggle depending on whether it is being used.

Applications Information
•
If the MCU is also going to be used in low power modes, be sure that all unused IO are programmed
properly for low power operation (typically best case is as outputs in the low state). The MC13192
is commonly used with the Freescale MC9S08GT/GB 8-bit devices. For these MCUs:
— Use only STOP2 and STOP3 modes (not STOP1) with these devices where the GPIO states are
retained. The MCU must retain control of the MC13192 IO during low power operation.
— As stated above all unused GPIO should be programmed as outputs low for lowest power and
no floating inputs.
— MC9S08GT devices have IO signals that are not pinned-out on the package. These signals must
also be initialized (even though they cannot be used) to prevent floating inputs.
