Atmel has released a new single RF data control transmitter family that is claimed to provide the industry's highest output power along with the lowest current consumption in a microcontroller-based RF transmitter. Alongside its other microcontroller products, Atmel also offers the advantages of embedded flash versions, which are easily and quickly reprogrammable. The family of ICs is provided with a broad range of design-in and support tools, which provides the design engineer with greater flexibility and helps to simplify the design-in process.
The ATAR862/T48C862 series has been developed especially for the demands of RF low-cost data transmission systems at data rates up to 32 kBaud. They can be used in both ASK (amplitude shift keying) and FSK (frequency shift keying) systems. The single transmitter ICs are well suited to be used along with Atmel's T574x and T576x PLL RF receivers. Due to their wide operating temperature ranges of -40 to +85°C/+125°C, the single RF transmitters can be used for a broad range of keyless-entry systems, consumer and industrial applications and TPM (tyre pressure monitoring) systems where +125°C is required.
The ATAR862/T48C862 feature integrated PLL loop filter, ESD protection and a single-ended antenna output. Atmel provides the single RF transmitter as well as Flash and ROM versions for the three standard carrier frequencies worldwide (315 MHz, 433 MHz and 868/915 MHz), providing an output power of maximum 8,0 dBm (868/915 MHz), maximum 10,0 dBm (433 MHz) and maximum 10,5 dBm (315 MHz), respectively.
