With integrated Cortex-M0, the chip can also transmit BLE beacons with only three external connections (power, ground, and antenna). The RF transmitter operates with >10% system efficiency at-10 dBm output power from a regulated supply. The entire chip, including the microprocessor, can operate below 1 mW peak power when transmitting. The analog receiver power consumption is 1.03 mW from a 1.5V battery. %G English %2 https://inria.hal.science/hal-02420868/document %2 https://inria.hal.science/hal-02420868/file/maksimovic19mrystal.pdf %L hal-02420868 %U https://inria.hal.science/hal-02420868 %~ INRIA %~ INRIA-ROCQ %~ TESTALAIN1 %~ INRIA-SILICONVALLEY %~ INRIA2 %~ INRIA-ETATSUNIS
