ATA5771C Overview
The Atmel® ATA5771C/73C/74C is a highly flexible programmable transmitter containing the Atmel AVR® microcontroller Atmel ATtiny44V and the UHF PLL transmitters in a small QFN24 5mm × 5mm package. This device is a member of a transmitter family covering several operating frequency ranges, which has been specifically developed for the demands of RF low-cost data transmission systems with data rates up to 32kBit/s...
ATA5771C Key Features
- Atmel® AVR® microcontroller and RF transmitter PLL in a single QFN24 5mm × 5mm package (pitch 0.65mm)
- Temperature range -40°C to +85°C
- Supply voltage 2.0V to 3.6V 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 / 7.5dBm at 433.92MHz / 5.5dBm at 868.3MHz
- Easy to design-in due to excellent isolation of the PLL from the PA and power supply
