Part No. W55RFS27R1B
Datasheet N/A
Description The Nuvoton W55RFS27R1B is a fully integrated, S-R (Super-regeneration) RF receiver with full-function baseband command decoder for R/C vehicles, toys, or wireless data communication applications. The W55RFS27R1B provides two input modes: uC-mode, for general-purpose, micro-controller interfaces to the RF transmitter (the decoder is disabled); and manual-mode, for a 6-function, baseband command decoder and RF receiver that works conveniently with the W55RFS27T1B to provide a simple remote control capability with low cost and high performance.
The W55RFS27R1B includes the Smart-DetectorWB function, which makes the W55RFS27R1B the most suitable receiver for mass-produced applications. Smart-DetectorWB overcomes the effects of component deviation and various kinds of environmental problems, such as temperature, moisture, or object-caused, antenna characteristic changes, to maintain maximum sensitivity.
The Super-Regenerative RF front-end architecture operates at 27 MHz, 35 MHz, 40 MHz, or 49MHz with a minimum number of external components. In addition, the W55RFS27R1B accommodates a wide range of operating voltages (2.1 V to 5.5 V) and supports 2- or 3-battery R/C applications.
