Description

The Atmel AT86RF401 Smart RF Microtransmitter is a highly integrated, low-cost RF transmitter, combined with an AVR RISC microcontroller. It requires only a crystal, a single LiMnO2 coin cell (CR2032 or similar), three capacitors, an inductor and a tunedloop antenna to implement a complete on-off keyed (OOK) wireless RF data transmitter.

In-system programmable, nonvolatile Flash program memory and EEPROM data storage make possible rapid time-to-market and lower inventory costs. Static current consumption is kept to a minimum with an ultra-low current shutdown mode. Normal operation resumes when a button is pressed. This activates the crystal oscillator circuit that serves as the clock for the AVR microcontroller. The RF carrier is synthesized utilizing an on-board Voltage Controlled Oscillator (VCO). Optimal tuning of the VCO is maintained over component tolerance through the use of a software-controlled switched capacitor array. Its accuracy is maintained with a PLL detector that compares the crystal oscillator to a frequency-scaled version (divided 24) of the RF carrier. The resulting error signal adjusts the VCO to produce a very stable RF carrier. An interrupt-based bit-timer structure, integral to the AVR microcontroller, simplifies the implementation of user-specific, data-bit encoding routines, such as PWM or Manchester, for modulating the RF carrier. Thirty-six of RF power output control is available to the user 1 dB steps and is addressable in software. The RF signal output is placed differentially on a tuned-loop antenna, which may be realized as a counterspread copper trace on a PCB. The AT86RF401 is fabricated in Atmel's 0.6 m Mixed Signal CMOS + EEPROM process, enabling true system-level integration (SLI). Figure 2. 20-lead TSSOP
