1 Introduction
The MC13191 is a short range, low power, 2.4 GHz
www.DataSheet4U.com
Industrial, Scientific, and Medical (ISM) band
transceivers. The MC13191 contains a complete packet
data modem which is compliant with the IEEE®
802.15.4 Standard PHY (Physical) layer. This allows the
development of proprietary point-to-point and star
networks based on the 802.15.4 packet structure and
modulation format. For full 802.15.4 compliance, the
MC13192 and Freescale's 802.15.4 MAC software are
required.
When combined with an appropriate microcontroller
(MCU), the MC13191 provides 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 to star
networks.

Features
For more detailed information about MC13191 operation, refer to the MC13191 Reference Manual, part
number MC13191RM.
Applications include, but are not limited to, the following:
• Remote control and wire replacement in industrial systems such as wireless sensor networks
• Factory automation and motor control
• Energy Management (lighting, HVAC, etc.)
• Asset tracking and monitoring
Potential consumer applications include:
• Home automation and control (lighting, thermostats, etc.)
• Human interface devices (keyboard, mice, etc.)
• Remote entertainment control
• Wireless toys
The transceiver includes a low noise amplifier, 1.0 mW power amplifier (PA), voltage controlled oscillator
(VCO), on-board power supply regulation, and full spread-spectrum encoding and decoding. The device
supports 250 kbps Offset-Quadrature Phase Shift Keying (O-QPSK) data in 2.0 MHz channels with
5.0 MHz channel spacing. The SPI port and interrupt request output are used for receive (RX) and transmit
(TX) data transfer and control.
2 Features
• IEEE 802.15.4 PHY Compliant
— 16 Channels
— Supports 250 kbps O-QPSK data in 5.0 MHz channels and full spread-spectrum encode/decode
— RX sensitivity of -91 dBm (typical) at 1.0% packet error rate
• Recommended power supply range: 2.0 to 3.4 V
• 0 dBm nominal, programmable from -27 dBm to 4 dBm typical maximum output power
• Buffered transmit and receive data packets for simplified use with low cost MCUs
• Three power down modes for power conservation:
— < 1.0 µA Off current
— 2.3 µA Typical Hibernate current
— 35 µA Typical Doze current (no CLKO)
• Two internal timer comparators available to reduce MCU resource requirements
• Programmable frequency clock output for use by MCU
• Onboard trim capability for 16 MHz crystal reference oscillator eliminates the need for external
variable capacitors and allows for automated production frequency calibration.
• Seven general purpose input/output (GPIO) signals
• Operating temperature range: -40 °C to 85 °C
• Small form factor QFN-32 Package
