    ASR5601N-ML has an RF transceiver and modem featuring high performance and low power consumption. It delivers a maximum of +10 dBm output RF power and achieves -98 dBm sensitivity at BLE 1 Mbps mode without off-chip power amplifier (PA) and TX/RX switch (TRSW). Moreover, an AUDIO-IN path supports both audio-in signals from analog and digital microphones (AMIC/DMIC). The analog audio-in path includes audio PGA, sigma-delta ADC (SD-ADC) as well as MIC bias voltage generation circuits (MICVB). This audio-in path enables flexible configuration to acquire audio signals for speech recognition in voice controlling application. The battery voltage range is extended from 1.7 V to 3.6 V with a flexible power management unit (PMU). The DCDC in PMU boosts the power efficiency of the entire chip. The ARM® Cortex™ M0+ MCU processes BLE software stacks and user’s application software The Cortex™-M0+ core ensures high efficiency and low power. With RF and modem, this SoC supports BLE 125K/500K/1M/2M bps data rates.
    ASR5601N-ML is designed to meet various kinds of IoT applications such as the data transmission, the remote controller and the speech recognition. OTP is integrated in order to enhance the system's security. A true random number generator (TRNG) is also integrated. Encryption of flash image file with key generated by TRNG protects user's software from illegal copying and ensures the safety of this SoC for IoT applications.
