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.
