General Description

nuvoton W55RFS27T1B 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.

W55RFS27T1B 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.

W55RFS27T1B cooperate with

W55RFS27R1B is very easy and convenient to

provide simple remote control function with very

low production cost in various application. The

transmitter provides the FCC/ETSI regulation

provisions for 27M, 35M, 40M, 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.

W55RFS27T1B 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.
