W55RFS27T3 DataSheet
General Description
nuvoton W55RFS27T3 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. W55RFS27T3 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.
W55RFS27T3 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.
W55RFS27T3 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. W55RFS27T3 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.
