CYTR12 - CY

CYTR12-V2.0 is a small-sized, low-power, long-distance wireless transceiver module. Low-cost, highly-integrated 2.4GHz wireless transceiver chip with integrated transmitter, receiver, frequency synthesizer, and GFSK modem on-chip. The transmitter supports adjustable power, and the receiver uses digital extended communication mechanisms to achieve excellent transceiver performance under complex environments and strong interference conditions. The peripheral circuit is simple, just need to match the MCU and a few peripheral passive devices.

CYTR12-V2.0 transmits GFSK signals, and the maximum transmit power can reach + 6dBm. The receiver uses a low-IF structure, and the receiving sensitivity can reach -96dBm＠62.5Kbps. Digital channel energy detection can monitor channel quality at any time. The on-chip transmits and receives FIFO registers can communicate with the MCU, store data, and then transmit over the air. It has built-in CRC, FEC, auto-ack and retransmission mechanisms, which can greatly simplify system design and optimize performance. The digital baseband supports 4-wire SPI interface. In addition, there are 2 digital interfaces: Reset and Pkt flag. In order to improve battery life, the chip reduces power consumption in all aspects. The minimum working voltage of the chip can reach 2.2V, and the minimum current is 1uA under the condition of holding the register value.

CYTR12-V2.0 module integrates all RF-related functions and devices. Users only need to perform simple register configuration through the SPL interface, which can realize communication and shorten the user's wireless product development cycle.
