Description
Silicon Laboratories’ Si4355 is an easy to use, low current, sub-GHz
EZRadio^® receiver. Covering all major bands, it combines plug-and-play
simplicity with the flexibility needed to handle a wide variety of
applications. The compact 3x3 mm package size combined with a low
external BOM count makes the Si4355 both space efficient and cost
effective. Excellent sensitivity of 116 dBm allows for a longer operating
range, while the low current consumption of 10 mA active and 50 nA
standby, provides for superior battery life. By fully integrating all
components from the antenna to the GPIO or SPI interface to the MCU,
the Si4355 makes realizing this performance in an application easy.
Design simplicity is further exemplified in the Wireless Development Suite
(WDS) user interface module. This configuration module provides
simplified programming options for a broad range of applications in an
easy to use format that results in both a faster and lower risk
development. Like all Silicon Laboratories’ EZRadio devices, the Si4355
is fully compliant with all worldwide regulatory standards, such as FCC,
ETSI, and ARIB.
