Bluetooth v5.0 + NFC Wireless Microcontroller
Built around the QN9090 from NXP, the CBT250 combines an ARM® Cortex®-M4 microcontroller with a high-performance Bluetooth v5.0 radio to offer OEM developers the ultimate in design flexibility. With 640 kB of executable flash, and 152 kB RAM, the CMP53x can host the end-user application. An optional 1 MB of additional flash offers integrated OTA FW support. Offering a wide variety of peripherals, the CBT250 can function as the core of a product design or interface to a host processor via a serial interface. Integrated NFC tag functionality offers the easiest, and most secure, method for pairing Bluetooth devices.
