Nuvoton’s W55RFS27T3B is a fully integrated S-R (Super-regeneration) RF transmitter with full-function of baseband command encoder for application of R/C vehicle, toy, or wireless data communication. W55RFS27T3B provides both uC-mode for general purpose of micro-controller programming interface and manual-mode for RF transmitter as well as 6-function of baseband command encoder.

W55RFS27T3B cooperate with W55RFS27R3B is very easy and convenient to provide simple remote control function for multi-player in various application. Built-in Channel-Share algorithm allows maximum 3 players playing simultaneously by using T3/R3B. The transmitter provides the FCC/ETSI regulation provisions for 27M and 49MHz S-R (Super-regeneration) modulation. Wide range of operation voltage from 2.2V to 5.5V is suitable for 2-battery or 3-battery R/C toy application, and high efficient transmission output power.

W55RFS27T3B is compliant to FCC part 15 class B and 15.227 / ETSI 300 220-1, making it easier for wireless end products to get FCC and ETSI compliance approval. W55RFS27T3B can be easily controlled by Winbond W55RC168 Digital-proportional R/C toy controller or a general purpose micro-controller to support R/C toy or wireless data communication.
