Revision A1

general R/C-vehicle control and 2 other user-

defined functions F1 and F2.

It is very suitable for remote control

applications if W55RFS27T1B and its associated

receiver/decoder W55RFS27R1B are adopted. The

very pair provides extremely low-cost and high-

performance function for design of various remote-

control applications.

The uC-mode provides digital interface for

external micro-controller to control the transmitter

easily and efficiently. The micro-controller only

need two pins, TXD (S1) to send data and ENB (S2)

to enter power down mode, if needed.

The transmitter provides the FCC/ETSI

regulation provisions for 27M, 40MHz 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

15dBm high efficient transmission output power.

W55RFS27T1B Super-regeneration RF

transmitter 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.
