Real-time execution is highly deterministic in thread mode, to and from sleep modes, and when handing events at configurable priority levels via the Nested Vectored Interrupt Controller(NVIC). The floating point unit (FPU) may generate exceptions when sed due to e.g. overflow or underflow. These exceptions will trigger the FPU interrupt. The 24-KB SRAMof 1024 byte page size and 192-KB flashof 8-KB block size memory are provided Power management DS-52810-03supporttwodifferentpowersupplyalternativesof Internal LDO mode and Low voltage mode. In internal LDO mode, the system power is generated directly from the supply voltage VDD. In low voltage mode, the system power is supplied by 1.8V. The module’s power management features are System OFF mode and System ON mode. In system OFF mode, the module is in deepest power saving mode. The system’s core functionality is powered down and all ongoing tasks are terminated. In system ON mode, the module is fully operational and CPU and selected peripherals can be brought into a state where they are functional and more or less responsive depending on the sub-power mode selected by Low power or Constant latency. Clock management The module has a 32MHz main crystal oscillator and 32.768kHz RTC crystal oscillator. Peripherals Page 6 of 15 DEASINO The general GPIO is organized as one port with up to 33 I/Os enabling access and control of up to 28 pins through one port. Each GPIO can be accessed individually with the following user configurable features. - Input/output direction - Output drive strength - Internal pull-up and pull-down resistors - Wake-up from high or low level triggers on all pins - Trigger interrupt on all pins - All pins can be used by the PPI task/event system. The maximum number of pins that canbe interfaced through the PPI at the same time is limited by the number of GPIOTEchannels - All pins can be individually configured to carry serial interface orquadrature demodulator signals. The transceiver receives and transmits data directly to and from system memory for flexible andefficient packet data management. The module's transceiver has the following features. - General modulation features .GFSK modulation .Data whitening .On-air data rates(250 kbps/1 Mbps/2 Mbps) - Transmitter with programmable output power of +4 dBm to-20 dBm, in 4 dB step - RSSI function(1 dB resolution) - Receiver with integrated channel filters achieving maximum sensitivity - Baseband controller .EasyDMA RX and TX packet transfer directly to and from RAM .Dynamic payload length .On-the-fly packet assembly/disassembly and AES CCM payload encryption . 8 bit, 16 bit and 24 bit CRC check The timer runs on the high-frequency clock source(HFCLK) and includes a four-bit (1/2X)prescaler that can divide the timer input clock from the HFCLK controller Clock source selectionbetween PCLK16M and PCLKlM is automatic according to timer base frequency set by the prescaler. The timer base frequency is always given as 16 MHz divided by the prescaler value. The PPI system allows a TIMER event to trigger a task of any other system peripheral ofdevice. The PPI system also enables the TIMER task/event features to generate periodic outputand PWM signals to any GPIO. The number of input/outputs used at the same time is limited bythe number of GPIOTE channels. Page 7 of 15 DEASINO The temperature sensor measures die temperature over the temperature range of the device with0. 25 degree resolution. The SPI is implemented with Easy DMA support for ultra low power serial communication from anexternal SPI master. Easy DMA in conjunction with hardware-based semaphore mechanismsremoves all real-time requirements associated with controlling the SPI slave from a low priority CPU execution context. The TWI slave with EasyDMA(TWIS) is compatible with I2C operating at 100 kHz and 400 kHz.The TWI transmitter and receiver implement Easy DMA. The Universal asynchronous receiver/transmitter with Easy DMA (UART) offers fast, full-duplex,asynchronous serial communication with built-in f…

EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION GFSK-1M Pt=-3.913dBm=0.41mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.41mW /5mm) .[√2.480(GHz)]= 0.13<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. GFSK-2M P t =-3.984dBm=0.40mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247.
