Product overview:

1. The Ci24R1 is a wireless transceiver chip that operates in the 2.4GHzISM band and is designed for low cost wireless applications with an embedded ARQ baseband protocol engine. The operating frequency range is 2400MHz-2525MHz, and there are 126 channels with 1MHz bandwidth.

2. The Ci24R1 uses GFSK/FSK digital modulation and demodulation technology. The data transmission rate and PA output power can be adjusted to support three data rates of 2Mbps,1Mbps, and 250Kbps. The high data rate allows the same data to be sent and received in less time and therefore can have lower power consumption.

3. Ci24R1 internal integration compatible with BLE4.2 standard PHY and MAC, can be very convenient to achieve data interaction with mobile phones.

4. The Ci24R1 operation mode is very convenient, and only requires the microcontroller (MCU) to configure a few registers on the chip through the second-line SPI interface, which can realize the data transceiver communication. The embedded ARQ baseband engine is based on the principle of packet communication, supports a variety of communication modes, and can be operated manually or fully automatic ARQ protocol. The internal integrated transceiver FIF0 can ensure continuous data transmission between the chip and MCU, and the enhanced ARQ baseband protocol engine can handle all high-speed operations, thus greatly reducing the MCU system consumption.

5. The Ci24R1 has a very low system application cost, and only requires an MCU and a few peripheral passive devices to form a wireless data transceiver system. Internal integration of high PSRR LDO power supply to ensure stable operation within a wide power supply range of 2.1-3.6V; Digital \/0 is compatible with 2.5V/3.3V/5V, etc

6. A variety of standard I/0 voltages, can be directly connected with various MCU ports, chip integrated crystal capacitor, can achieve crystal temperature compensation, to achieve a wide temperature range of work
