CC2500 processing chip is a low-power and low-cost wireless transceiver module released by TI (the original Chipcon was recycled by TI). Its carrier range is adjustable from 2.400GHz to 2.483GHz, mainly used to complete multi-channel communication. It supports a variety of modulation methods, including FSK, GFSK, OOK and MSK, and the maximum data transmission rate can reach 500kb/s. CC2500 also provides additional hardware configuration support for data packet solution, data information cache, single-pulse transmission, idle channel evaluation, connection quality identification and electromagnetic induction call. It has four main situations: RX, TX, IDLE and SLEEP
(1) 2400-2483.5MHz ISM and SRD frequency band
(2) The maximum working speed is 500kbps, supporting 2-FSK, GFSK and MSK modulation methods
(3) High sensitivity (- 101dBm at 10Kbps 1%)
(4) Embedded hardware configuration CRC error control and point-to-multipoint communication detailed address manipulation
(5) Relatively low current consumption (13.3mA in RX)
(6) Programmable power, up to 1dBm for each support frequency
(7) Support small power radio wave excitation
(8) Support automatic channel cleaning before transmission (CCA), i.e. carrier communication monitoring system software
(9) The appropriate frequency bounce system software brought by the mixer with rapid frequency change
(10) The detailed address of the control module can be set by the mobile software, and the program programming is very convenient
(11) Standardize DIP interval socket, which is conducive to embedded development
(12) Independent 64-byte RX and TX data information FIFO
