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.

1.1 Features

•

Operating frequency: 27 MHz ~ 49 MHz

Wide operating voltage: 2.2 V ~ 5.5 V

Two input modes—uC-mode and manual-mode—for more flexibility

(uC-mode) Transmission data rate up to 10 Kbps for 30%-70% duty cycle signals

(manual-mode) Winbond-patented, channel-sharing algorithm that allows up to 3 players

simultaneously on the same frequency band

•

(manual-mode) R/C toy baseband control command encoder, supporting 4 or 6 functions: Forward,

Backward, Left-turn, Right-turn, and 2 user-defined functions F1 and F2 (user-defined functions

not available in 4-function mode)

•

15-dBm, high-efficiency transmissions (50 Ω) with minimum current consumption

Power-down current consumption less than 1 uA

Fewer external components required

Compliant with FCC part 15 Subpart C 15.227(15.235) / ETSI 300 220-1 low-power and short-

range device requirements

•

Operating temperature: 0°C ~ 70°C

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.
