ATA8741
Microcontroller with UHF ASK/FSK Transmitter
DATASHEET
General Features
â Transmitter with microcontroller consisting of an AVR® microcontroller and RF
transmitter PLL in a single QFN24 5mm à 5mm package (pitch 0.65mm)
â f0 = 310MHz to 350MHz
â Temperature range â40°C to +85°C
â Supply voltage 2.0V to 4.0V allowing usage of single li-cell power supply
â Low power consumption
â Active mode: typical 9.8mA at 3.0V and 4MHz microcontroller-clock
â Power-down mode: typical 200nA at 3.0V
â Modulation scheme ASK/FSK
â Integrated PLL loop filter
â Output power of 8dBm at 315MHz
â Easy to design-in due to excellent isolation of the PLL from the PA and power
supply
â Single-ended antenna output with high efficient power amplifier
â Very robust ESD protection: HBM 2500V, MM100V, CDM 1000V
â High performance, low power AVR 8-bit microcontroller, similar to popular Atmel
ATtiny44
â Well known and market-accepted RISC architecture
â Non-volatile program and data memories
â 4Kbytes of in-system programmable program memory flash
â 256Bytes in-system programmable EEPROM
â 256Bytes internal SRAM
â Programming lock for self-programming flash program and EEPROM data security
â Peripheral features
â Two timer/counter, 8- and 16-bit counters with two PWM channels on both
â 10-bit ADC
â On-chip analog comparator
â Programmable watchdog timer with separate on-chip oscillator
â Universal serial interface (USI)
