MRF89XAM8A

DEVICE OVERVIEW
1.1
Interface description
The MRF89XAM8A is an ultra-low power sub-GHz
surface mount transceiver module with integrated
crystal, internal voltage regulator, matching circuitry
and PCB antenna. The MRF89XAM8A module
operates in the European 863–870 MHz frequency
band and is ETSI compliant. The integrated module
design frees the integrator from the extensive RF and
antenna design, and regulatory compliance testing,
allowing quicker time to market.
The MRF89XAM8A module is compatible with
Microchip’s MiWi? Development Environment
software stacks. The software stacks are available as a
free download, including source code, from the
Microchip’s web site
http://www.microchip.com/wireless .
The MRF89XAM8A module has been tested and
conforms to EN 300 220-2 V2.3.1 (2001–02) and EN
301 489-3 V1.4.1 (2002–08) European Standards. The
module tests can be applied toward final product
certification and Declaration of Conformity (DoC). To
maintain conformance, refer to module settings in
Section 1.3, Operation . Additional testing may be
required depending on the end application.
The simplified block diagram of the MRF89XAM8A
module is illustrated in Figure 1-1 . The module is based
on the Microchip Technology MRF89XA ultra-low
power sub-GHz transceiver Integrated Circuit (IC). The
module interfaces to many popular Microchip PIC ?
microcontrollers through a 3-wire serial SPI interface,
two chip selects (configuration and data), two interrupts
Interrupt Request 0 (IRQ0) and Interrupt Request 1
(IRQ1), Reset, power and ground as illustrated in
Figure 1-2 . Table 1-1 provides the related pin
descriptions.
Serial communication and module configuration are
documented in the “ MRF89XA Ultra-Low Power,
Integrated Sub-GHz Transceiver ” (DS70622) Data
Sheet. Refer to the “ MRF89XA Data Sheet” for specific
serial interface protocol and general register
definitions. Also, see Section 1.3, Operation for
specific register settings that are unique to the
MRF89XAM8A module operation to maintain
regulatory compliance.
