Data Transfer Modes
The 802.15.4 modem 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.

Packet Structure
Figure 7
shows the packet structure of the 802.15.4 modem. Payloads of up to 125 bytes are supported.
The 802.15.4 modem 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 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 in Packet Mode). 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. A
parameter of received energy during the reception called the Link Quality Indicator is measured over a 64
μ
s period after the packet preamble and stored in an SPI register.
If the 802.15.4 modem is in Packet Mode, the data is stored in RAM and processed as an entire packet.
The MCU is notified that an entire packet has been received via an interrupt.
If the 802.15.4 modem is in streaming mode, the MCU is notified by a recurring interrupt on a
word-by-word basis.
Figure 8
shows CCA reported power level versus input power. Note that CCA reported power saturates at
about -57 dBm input power which is well above IEEE 802.15.4 Standard requirements.
Figure 9
shows
energy detection/LQI reported level versus input power.
