QN9030T

QN9090 QN9090(T)/QN9030(T) Bluetooth Low Energy 5.0 wireless MCU Rev. 1.2 — May 2021 Product data sheet 1. General description The QN9090 and QN9090T (called QN9090 throughout this document) are ultra-low power, high performance Arm® Cortex®-M4 based wireless microcontrollers supporting Bluetooth Low Energy 5.0 to facilitate the development of Bluetooth Low Energy applications. The QN9090, supporting eight simultaneous connections, includes a 2.4 GHz Bluetooth Low Energy 5 compliant transceiver and a comprehensive mix of analog and digital peripherals. Ultra-low current consumption in both radio receive and transmit modes and also in the power down modes allow use of coin cell batteries. The product has 640 KB embedded Flash, 152 KB RAM memory. The embedded flash can support Over The Air (OTA) code download to applications. The devices include 10-channel PWM, two timers, one RTC/alarm timer, a Windowed Watchdog Timer (WWDT), two USARTs, two SPI interfaces, two I2C interfaces, a DMIC subsystem with dual-channel PDM microphone interface with voice activity detector, one 12-bit ADC, temperature sensor and comparator. The QN9090T variant has an internal NFC tag with connections to the external NFC antenna. The QN9030 variant has the same functionality as the QN9090 except for reduced memory sizes of 320 KB embedded Flash, 88 KB RAM. The QN9030T variant has the functionality of the QN9030 with the addition of an embedded NFC tag. The Arm Cortex-M4 is a 32-bit core that offers s...
