ATA8742
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 = 429MHz to 439MHz
● 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 7.5dBm at 433.92MHz
● Easy to design-in due to excellent isolation of the PLL from the PA and power
supply
● Single-ended antenna output with high efficient power amplifier
● Very robust ESD protection: HBM 2500V, MM100V, CDM 1000V
● High performance, low power AVR 8-bit microcontroller, similar to popular Atmel^®
ATtiny44
● Well known and market-accepted RISC architecture
● Non-volatile program and data memories
● 4KBytes of in-system programmable program memory flash
● 256Bytes in-system programmable EEPROM
● 256Bytes internal SRAM
● Programming lock for self-programming flash program and EEPROM data security
● Peripheral features
● Two Timer/Counter, 8- and 16-bit counters with Two PWM channels on both
● 10-bit ADC
● On-chip analog comparator
● Programmable watchdog timer with separate on-chip oscillator
● Universal serial interface (USI)
