W55RFS27T1B Datasheet, PDF (7/15 Pages) Winbond – SUPER-REGENERATION RF TRANSMITTER

W55RFS27T1B DataSheet
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.
