ATA8741
Microcontroller with UHF ASK/FSK Transmitter
DATASHEET
General Features
● Transmitter with microcontroller consisting of an AVR® microcontroller and RF transmitter PLL in a single QFN24 5mm × 5mm package (pitch 0.
65mm) ● f0 = 310MHz to 350MHz
● Temperature range –40°C to +85°C ● Supply
voltage 2.
0V to 4.
0V allowing usage of single li-cell power supply ● Low power consumption
● Active mode: typical 9.
8mA at 3.
0V and 4MHz microcontroller-clock ● Power-down mode: typical 200nA at 3.
0V ● Modulation scheme ASK/FSK ● Integrated PLL loop filter ● Output power of 8dBm at 315MHz ● Easy to design-in due to excellent isolation of the PLL from the PA and power supply ● Single-ended antenna outpu...
