ATA8520D Single-Chip SIGFOX RF Transceiver DATASHEET Features Fully integrated, single-chip RF transceiver (SIGFOX compliant) System-on-chip solution including SIGFOX related protocol handling for modem operation AVR microcontroller core with embedded firmware, SIGFOX, protocol stack and ID/PAC Supports up- and downlink operation, i.e. transmit and receive of data telegrams with SIGFOX base stations Operating frequencies: for uplink 868.0 to 868.6MHz, for downlink 869.4 to 869.65MHz Low current consumption: 32.7mA during transmit and 10.4mA during receive operation Typical OFF mode current: 5nA (maximum 600nA at V = +3.6V and T = +85C) S Data rate: 100bit/s with DBPSK modulation for uplink and 600bit/s with GFSK modulation for downlink SPI interface for data access and transceiver configuration and control Event signal indicates the status of the IC to an external microcontroller Power-up (typical 10ms OFF mode -> IDLE mode) Supply voltage ranges 1.9V to 3.6V and 2.4V to 5.5V (SIGFOX compliant supply range 3V5% and 3.3V to 5.5V) Temperature range 40C to +85C ESD protection at all pins (4kV HBM, 200V MM, 750V FCDM) Small 5 5mm QFN32 package/pitch 0.5mm Applications SIGFOX compatible modem for long-range, low-power and low-cost applications using the SIGFOX network Home and building automation Alarm and security systems Smart environment and industrial Smart parking Tracking Metering 9390E-INDCO-11/151. General Description 1.1 Introduction The Atmel ATA8520D is a highly integrated, low-power RF transceiver with an integrated AVR microcontroller for applications using the wide area SIGFOX network The Atmel ATA8520D is partitioned into three sections: an RF front end, a digital baseband and the low-power 8-bit AVR microcontroller. The product is designed for the ISM frequency band in the range of 868.0MHz to 868.6MHz and 869.4 to 869.65MHz. The external part count is kept to a minimum due to the very high level of integration in this device. By combining outstanding RF performance with highly sophisticated baseband signal processing, robust wireless communication can be easily achieved. The transmit path uses a closed loop fractional-N modulator. The SPI interface enables external control and device configuration. 1.2 System Overview Figure 1-1. Circuit Overview AVCC VS DVCC Supply and Reset RF Frontend CPU RF IN Mixer ADC RX TX DSP RF OUT PLL DATA BUS XTO Port B Port C PB 7..0 PC 5..0 (SPI) XTAL Figure 1-1 shows an overview of the main functional blocks of the Atmel ATA8520D. External control of the Atmel ATA8520D is performed through the SPI pins SCK, MOSI, MISO, and NSS. The functionality of the device is defined by the internal firmware and processed by the AVR. SPI commands are used to control the device and to start the data telegram transmission. The end of the telegram transmission is signaled to an external microcontroller on pin 28 (PB6/EVENT). It is important to note that all PWRON and NPWRON pins (PC1..5, PB4, PB7) are active in OFF mode. This means that even if the Atmel ATA8520D is in OFF mode and the DVCC voltage is switched off, the power management circuitry within the Atmel ATA8520D biases these pins with VS. The AVR microcontroller ports can be used as button inputs, LED drivers, EVENT pin, general purpose digital inputs, or wake-up inputs, etc. Functionality of these ports is already implemented in the firmware. 2 ATA8520D DATASHEET 9390EINDCO11/15 Peripherals Firmware SIGFOX Protocol Stack ID and PAC
