1. Descriptions of RF Transceiver IC CMT2380F32W:

Employed a 32-bit Cortex-M0+ CPU core and an ultra-low power RF transceiver, the CMT2380F32W is a FSK, GFSK, MSK, GMSK and OOK wireless MCU with high performance and ultra-low power applying to 127 to 1020 MHz band wireless applications. Operating with 1.8 to 3.6 V supply voltage, the CMT2380F32W consumes only 72 mA current while delivering up to 20 dBm power. 

2. Features of RF Transceiver IC CMT2380F32W:

MCU Features

• 32 MHz Cortex-M0+ 32-bit CPU platform

• 32 kB Flash with erasing protection

• 4 kB RAM with parity to enhance system stability

• 16 general purpose I/O interfaces available

• Flexible power management system

* 0.5 uA @ 3 V(deep sleep mode): the power consumption when all clocks are off, power-on reset is active, I/O state is maintained, I/O interrupt is active and all registers, RAM, and

CPU stay in data storage status

* 0.8 uA @ 3 V (deep sleep mode): the power consumption when RTCs work

* 150 uA/MHz @3 V @16 MHz: the power consumption when CPU and peripheral modules

run with program Flash operating internally
