AWAC24U
Data Sheet
Functional Overview
The AWAC24U Module provides a complete USB to RF antenna wireless MODEM. The module is designed to implement wireless
device links operating in the worldwide 2.4-GHz ISM frequency band. It is intended for systems compliant with world-wide
regulations covered by ETSI EN 301 489-1 V1.41, ETSI EN 300 328-1 V1.3.1 (Europe), FCC CFR 47 Part 15 (USA and Industry
Canada) and TELEC ARIB(Japan).
The module contains a 2.4-GHz 1-Mbps GFSK radio transceiver, packet data buffering, packet framer, DSSS baseband controller,
Received Signal Strength Indication (RSSI), and SPI interface for data transfer and device configuration.
The radio supports 98 discrete 1-MHz channels (regulations limit the use of some of these channels in certain jurisdictions, contact
Artaflex for more details). In DSSS modes the baseband performs DSSS spreading/de-spreading, while in GFSK Mode (1 Mb/s GFSK) the baseband performs Start of Frame (SOF), End of Frame (EOF) detection and CRC16 generation and checking. The
baseband may also be configured to automatically transmit Acknowledge (ACK) handshake packets whenever a valid packet is
received.
When in receive mode, with packet framing enabled, the device is always ready to receive data transmitted at any of the supported
bit rates, except SDR, enabling the implementation of mixed-rate systems in which different devices use different data rates. This
also enables the implementation of dynamic data rate systems, which use high data rates at shorter distances and/or in a lowmoderate interference environment, and change to lower data rates at longer distances and/or in high interference environments.
4.1
Link Layer Modes
The AWAC24U module supports the following data packet framing features:
SOP – Packets begin with a 2-symbol Start of Packet (SOP) marker. This is required in GFSK and 8DR modes, but is optional in
DDR mode and is not supported in SDR mode; if framing is disabled then an SOP event is inferred whenever two successive
correlations are detected. The SOP_CODE_ADR code used for the SOP is different from that used for the “body” of the packet and
if desired may be a different length. SOP must be configured to be the same length on both sides of the link.
EOP – There are two options for detecting the end of a packet. If SOP is enabled, then a packet length field may be enabled.
GFSK and 8DR must enable the length field. This is the first 8-bits after the SOP symbol, and is transmitted at the payload data
rate. If the length field is enabled, an End of Packet (EOP) condition is inferred after reception of the number of bytes defined in the
length field, plus two bytes for the CRC16 (if enabled—see below). The alternative to using the length field is to infer an EOP
condition from a configurable number of successive non-correlations; this option is not available in GFSK mode and is only
recommended to enable when using SDR mode.
CRC16 – The device may be configured to append a 16-bit CRC16 to each packet. The CRC16 uses the USB CRC polynomial
with the added programmability of the seed. If enabled, the receiver will verify the calculated CRC16 for the payload data against
the received value in the CRC16 field. The starting value for the CRC16 calculation is configurable, and the CRC16 transmitted
may be calculated using either the loaded seed value or a zero seed; the received data CRC16 will be checked against both the
configured and zero CRC16 seeds.
CRC16 detects the following errors:
• Any one bit in error
• Any two bits in error (no matter how far apart, which column, and so on)
• Any odd number of bits in error (no matter where they are)
• An error burst as wide as the checksum itself
4.2
Packet Buffers
All data transmission and reception utilizes the 16-byte packet buffers—one for transmission and one for reception.
The transmit buffer allows a complete packet of up to 16-bytes of payload data to be loaded in one burst SPI transaction, and then
transmitted with no further micro controller intervention. Similarly, the receive buffer allows an entire packet of payload data up to
16 bytes to be received with no firmware intervention required until packet reception is complete.
The AWAC24U module supports packet length of up to 40 bytes; interrupts are provided to allow a micro controller to use the
transmit and receive buffers as FIFOs. When transmitting a packet longer than 16 bytes, the micro controller can load 16-bytes
initially, and add further bytes to the transmit buffer as transmission of data creates space in the buffer. Similarly, when receiving
packets longer than 16 bytes, the micro controller must fetch received data from the FIFO periodically during packet reception to
prevent it from overflowing.

4.3
AWAC24U
Data Sheet
Auto Transaction Sequencer (ATS)
The AWAC24U module provides automated support for transmission and reception of acknowledged data packets.
When transmitting a data packet, the device automatically starts the crystal and synthesizer, enters transmit mode, transmits the
packet in the transmit buffer, and then automatically switches to receive mode and waits for a handshake packet and then
automatically reverts to sleep mode or idle mode when either an ACK packet is received, or a timeout period expires.
Similarly, when receiving in transaction mode, the device waits in receive mode for a valid packet to be received, and then
automatically transitions to transmit mode, transmits an ACK packet, and then switches back to receive mode to await the next
packet. The contents of the packet buffers are not affected by the transmission or reception of ACK packets.
In each case, the entire packet transaction takes place without any need for micro controller firmware action; to transmit data the
micro controller simply needs to load the data packet to be transmitted, set the length, and set the TX GO bit. Similarly, when
receiving packets in transaction mode, firmware simply needs to retrieve the fully received packet in response to an interrupt
request indicating reception of a packet.

Notes
[1]. Typically data modes with high chip encoding which provides a higher process gain and lower data rates provide longer range and / or a more
robust wireless link.
[2]. This mode is compatible with Cypress Generation 1 RF WirelessUSB transceiver devices, CYWUSB6934 and CYWUSB6935.
[3]. It is permissible to connect voltages above VIO to inputs through a series resistor limiting input current to 1 mA. AC timing not guaranteed.
[4]. Human Body Model (HBM).

FCC Operating Requirements in North America
Customer should make sure that maximum power setting i.e PA7 is only used between CH06-65. For Channels
outside CH No. 06-65 i.e CH No. 01-04 and 66-79 the maximum power level allowed is PA3. Any configuration other
than what’s mentioned above will violate the FCC grant issued for this hardware.
8.2
ETSI Operating Requirements for EU
Device can operate between CH No. 01-79 only with Power setting equal or below PA3. Using any setting above PA3
will violate the ETSI regulations for max output power.
9
RF Exposure Requirements
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer
than this distance is not recommended.
The antenna is integrated in the module and has been qualified and approved for use under the Approval certification. This antenna
may not be modified or altered in any way from the original design as represented by Artaflex Inc.
The integrated antenna has been specifically tested with the AWAC24U, and certified through the regulatory agencies in the US,
Canada, and European Union for authorized use. Use of an altered antenna in the AWAC24U will void certification. Changes or
