SI4355-C2A-GMR

SI4355-C2A-GMR is a Si4355 EZRadio receiver. It is a receiver-only device based on the Si4x55 architecture. The compact 3x3mm package size combined with a low external BOM count makes the Si4x55 both space-efficient and cost-effective. By fully integrating all components from the antenna to the GPIO or SPI interface to the MCU, 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 results 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. Typical applications are remote control, home security and alarm, telemetry, garage and gate openers, remote keyless entry, home automation, industrial control, sensor networks, health monitors.
