Overview:

CMT2380F64 integrates a 32-bit ARM Cortex®-M0 core with a super low power consumption RF transceiver. It is a high efficiency super-low power MCU, applying for wireless application of (G) FSK、(G) MSK  and OOK transceiver from 127 to 1020 MHz.CMT2380F64 is an ultra-low power, high performance, OOK (G) FSK RF transceiver suitable for a variety of 140 to 1020 MHz wireless applications. CMT2380F64 operates from 1.8 V to 3.6 V and supports up to +20 dBm TX power consumption and -121 dBm receiving sensitivity with the corresponding TX current and RX current of 72 mA and 8.5 mA.(MCU power consumption is not included). CMT2380F64 integrates a wealth of peripherals supports standard UART, I2C and SPI interface, with up to 23 general IO ( CMT2380F64-EQR40）/ 30 general IO（CMT2380F64-EQR48）, supports internal high speed /low speed low power consumption RC oscillator and 32.768 kHz external crystal oscillator, supports a variety of packet formats and encoding and decoding methods up to 64-byte Tx/Rx FIFO, supports featured rich RF GPIO, a variety of low power operation mode and fast startup mechanism, high precision RSSI, manual fast frequency hopping and 12 bit high speed ADCmulti-channel input,etc. CMT2380F64 has a small QFN package size of 5mmx5mm/6mmx6mm, which is ideal for small size and power consumption of Internet applications.
