SI4455-C2A-GM

The SI4455-C2A-GM is an easy-to-use low-current OOK/(G) FSK Sub-GHz Transceiver combines plug-and-play simplicity with the flexibility needed to handle a wide variety of applications. The +13dBm output power and excellent sensitivity of -116dBm allows for a longer operating range, while the low current consumption of 18mA TX (at 10dBm), 10mA RX and 40nA standby, provides for superior battery life. By fully integrating all components from the antenna to the GPIO or SPI interface to the MCU, the Si4x55 makes it easy to realize this performance in an application. Design simplicity is further exemplified in the wireless development suite (WDS) user interface software. WDS provides simplified programming options for a broad range of applications in an easy-to-use format that result in faster and lower risk development. The Si4x55 is capable of supporting major worldwide regulatory standards, such as FCC, ETSI, ARIB and China regulatory standards.
