Description

GND

10 11 GPIO1

Silicon Laboratories’ Si4455 is an easy-to-use, low current, sub-GHz

EZRadio^®transceiver. The Si4055 is a transmit-only device, and the Si4355

is a receiver-only device based on the Si4x55 architecture. This data sheet

covers all three products with the transmit descriptions being relevant for

Si4455 and Si4055 and the receive descriptions being relevant for Si4455

and Si4355. 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 Si4x55 both space efficient and cost effective. The +13 dBm

output power and excellent sensitivity of –116 dBm allows for a longer

operating range, while the low current consumption of 18 mA TX (at 10 dBm),

10 mA RX, and 40 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 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 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.
