1.7.1 Transceiver overview
The transceiver (see Figure 1-1 ) is a single-chip integrated circuit ideally suited for today's high
performance ISM band RF applications. Its advanced features set, including state of the art packet engine,
greatly simplifies system design while the high level of integration reduces the external RF component bill
of material (BOM) to a handful of passive de-coupling and matching components. It is intended for use as
a high-performance, low-cost FSK and OOK RF transceiver for robust, frequency agile, half-duplex
bidirectional RF links.
The MKW01 is intended for applications over a wide frequency range, including the 433 MHz and
868 MHz European and the 902–928 MHz North American and Japan ISM bands. Coupled with a link
budget in excess of 135 dB, the transceiver advanced system features include a 66 byte TX/RX FIFO,
configurable automatic packet handler, listen mode, temperature sensor and configurable DIOs which
greatly enhance system flexibility while at the same time significantly reducing MCU requirements. The
transceiver complies with both ETSI and FCC regulatory requirements.
The major RF communication parameters of the MKW01 transceiver are programmable and most can be
dynamically set. This feature offers the unique advantage of programmable narrow-band and wide-band
communication modes without the need to modify external components. The transceiver is also optimized
for low power consumption while offering high RF output power and channelized operation.
The versatile RF Transceiver in the MKW01 can be configured to be compliant with the relevant sections
of numerous world-wide standards, including but not limited to: FCC Part 15.247 and Part 15.249, ETSI
EN 300 220, ARIB STD-T108, IC RSS 210.
1.7.2 MCU overview
The in-package Kinetis L series 48 MHz MCU features an ARM Cortex M0+, 16 KB Ram and 128 KB
flash. The RF transceiver is controlled through the MCU SPI port which is dedicated to the RF device
interface. Two of the transceiver status IO lines are also directly connected to the MCU GPIO to monitor
the transceiver operation. In addition, the transceiver reset and additional status can be connected to the
MCU through external connections.
