Introduction
The Alpha Modules are extremely cost effective but high performance radio modules. Supplied in a
miniature Surface mount package this Transceiver module can Transmit/Receive at up to 115Kbps at a
maximum of 300m.
Operating at 2.2-3.6V, the module monitors its battery voltage and can sleep with very low standby
current. The module can wake intermittently and provide direct control outputs to a microcontroller
making it ideally suited to battery applications.
These Modules will suit one to one multi-node wireless links in applications including car and building
security, POS and inventory tracking, remote process monitoring.

ALPHA RF Transceiver
Programming Guide
Brief Description
ALPHA-TRX supports a command interface to setup frequency, deviation, output power and
also data rate. There is no need to change any hardware when using frequency-hopping
applications.
Commands to the transmitter are sent serially. Data bits on pin SDI are shifted into the
device upon the rising edge of the clock on pin SCK whenever the chip select pin nSEL is low.
When the nSEL signal is high, it initializes the serial interface. All commands consist of a
command code, followed by a varying number of parameter or data bits. All data are sent MSB
first (e.g. bit 15 for a 16- bit command). Bits having no influence (don’t care) are indicated
with X. Special care must be taken when the microcontroller’s builtin hardware serial port is
used. If the port cannot be switched to 16-bit mode then a separate I/O line should be used to
control the nSEL pin to ensure the low level during the whole duration of the command or a
software serial control interface should be implemented. The Power-On Reset (POR) circuit
sets default values in all control and command registers. The receiver will generate an
interrupt request (IT) for the microcontroller - by pulling the nIRQ pin low - on the following
events:
•
The TX register is ready to receive the next byte (RGIT)
•
The RX FIFO has received the pre-programmed amount of bits (FFIT)
•
Power-on reset (POR)
•
RX FIFO overflow (FFOV) / TX register underrun (RGUR)
•
Wake-up timer timeout (WKUP)
•
Negative pulse on the interrupt input pin nINT (EXT)
•
Supply voltage below the pre-programmed value is detected (LBD)
