W55RFS27T3B
1. GENERAL DESCRIPTION
The Winbond W55RFS27T3B is a fully-integrated, S-R (Super-regeneration) RF transmitter with full-
function baseband command encoder and a Winbond-patented, channel-sharing algorithm that
supports up to three players simultaneously. As such, the W55RFS27T3B is suitable for R/C vehicles,
toys, or wireless data communication applications.
The W55RFS27T3B provides two input modes: uC-mode, for general-purpose, micro-controller
interfaces with the RF transmitter; and manual-mode, for a 3-player, 6-function, baseband command
encoder and RF transmitter. In manual-mode, the W55RFS27T3B works conveniently with up to
three W55RFS27R3C chips to provide a simple, multi-player remote control capability with low cost
and high performance.
The S-R RF transmitter operates on 27 MHz, 35 MHz, 40 MHz, or 49 MHz with a default data rate of
2.5 KBPS, and it is compliant with FCC part 15 Subpart C 15.227(15.235) and ETSI 300 220-1,
making it easier for wireless end products to get FCC and ETSI compliance approval.
In addition, the W55RFS27T3B accommodates a wide range of operating voltages (2.2 V to 5.5 V),
supports 2- or 3-battery R/C toy applications, and generates highly-efficient transmissions.

W55RFS27T3B
2.2 W55RFS27T3B Functional Description
The W55RFS27T3B provides two operating modes, Manual-mode and uC-mode, for remote control
product development.
In Manual-mode, the W55RFS27T3B encodes one of up to six functions for one of up to three players,
modulates it with the on-chip RF power amplifier, and transmits it to the receiver(s) (e.g.,
W55RFS27R3C). This transmission occurs in the same frequency band for all players, as this
frequency band is divided using a Winbond-patented, channel-sharing algorithm. Manual-mode
supports up to six functions: Forward, Backward, Left-turn, Right-turn (for general R/C-vehicle control)
and two user-defined functions F1 and F2.
uC-mode provides a digital interface for any external micro-controller to control the S-R RF transmitter
easily and efficiently. This interface uses two W55RFS27T3B pins: TXD (S1), to send data; and ENB
(S2), to tell the W55RFS27T3B to enter and exit power-down mode, as needed.
The transmitter meets FCC/ETSI regulations for 27 MHz, 40 MHz and 49 MHz S-R (Super-
regeneration) modulation, and it is compliant with FCC part 15 Subpart C 15.227(15.235) and ETSI
300 220-1, making it easier for wireless end products to get FCC and ETSI compliance approval..
In addition, the W55RFS27T3B accommodates a wide range of operating voltages (2.2 V to 5.5 V),
supports 2- or 3-battery R/C toy applications, and transmits at 15 dBm very efficiently.
