RF67 - Integrated Transmitter IC
Narrow/wideband 315 MHz, 434 MHz 868 MHz and 915 MHz band Transmitter
GENERAL DESCRIPTION
The RF67 is a fully integrated transmitter which can
operate in the 315, 434, 868 and 915 MHz licence free ISM
bands.
The transmitter has two modes of operation, a conventional
MCU controlled mode and a ‘stand-alonemode which
enables the RF67 to download configuration and
messages from an E2PROM in response to a user input.
Stand-alone mode makes the RF67 ideal for miniaturized or
low cost remote keyless entry (RKE) applications. It also
offers the unique advantage of narrow-band and wide-band
communication in a range of modulation formats.
The RF67 offers high RF output power and channelized
operation suited for the European (ETSI EN 300-220-1),
North American (FCC part 15.231, 15.247 and 15.249) and
Japanese (ARIB T-67) regulatory standards.

DATASHEET
The RF67 also includes two timing references; an RC oscillator, for sleep mode operation of the SPI interface (in MCU
mode), and a 32 MHz crystal oscillator, which serves as the low-noise frequency reference of the PLL. The references and
supply voltages are provided by the power distribution system which includes several regulators allowing true battery
powered operation.

4.2.2. MCU Mode
The RF67 is also capable of operating in a conventional MCU controlled mode. Figure 4 shows the RF67 operating in
MCU mode and connected to an external microcontroller. Note that CLKOUT provides the oscillator signal for the MCU,
thus negating the need for two crystal oscillators. The DCLK connection is also optional - only being required if the data
rate is to be determined by RF67 or transmit filtering is to be used.
