W55RFS27T1B
1. GENERAL DESCRIPTION
The Winbond W55RFS27T1B is a fully integrated, S-R (Super-regeneration) RF transmitter with
full-function baseband command encoder for R/C vehicles, toys, or wireless data communication
applications.
The W55RFS27T1B provides two input modes: uC-mode, for general-purpose, micro-controller
interfaces to the RF transmitter; and manual-mode, for a 6-function, baseband command encoder and
RF transmitter that works conveniently with the W55RFS27R1B to provide a simple remote control
capability with low cost and high performance.
The S-R RF transmitter meets FCC/ETSI regulations for 27 MHz, 35 MHz, 40 MHz, and 49 MHz S-R
(Super-regeneration) modulation, and it is compliant with 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.
In addition, the W55RFS27T1B accommodates a wide range of operating voltages (2.2 V to 5.5 V),
supports 2-battery or 3-battery R/C applications, and transmits very efficiently.

W55RFS27T1B
2.2 W55RFS27T1B Functional Description
The W55RFS27T1B provides two operating modes, Manual-mode and uC-mode, for remote-control
product development.
In Manual-mode, the W55RFS27T1B encodes one of up to six functions, modulates it with the on-chip
RF power amplifier, and transmits it to the receiver (e.g., W55RFS27R1B). This 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. The micro-controller only uses two pins: TXD (S1), to send data; and ENB (S2), to
tell the W55RFS27T1B to enter and exit power-down mode, as needed.
The transmitter meets FCC/ETSI regulations for 27 MHz, 35 MHz, 40 MHz, and 49 MHz S-R
(Super-regeneration) modulation, and it is compliant with 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.
In addition, the W55RFS27T1B accommodates a wide range of operating voltages (2.2 V to 5.5 V),
supports 2-battery or 3-battery R/C applications, and transmits at 15 dBm very efficiently.
