Description

The Winbond W55RFS27R3C is a fully integrated, S-R (Super-regeneration) RF receiver with fullfunction baseband command decoder for R/C vehicles, toys, or wireless data communication applications.

The W55RFS27R3C provides two input modes: uC-mode, for general-purpose, micro-controller interfaces to the RF transmitter (the decoder is disabled); and manual-mode, for a 6-function, baseband command decoder and RF receiver. Manual-mode is also designed with the Winbondpatented ChannelSharedWB protocol for multi-player applications, and up to three players are allowed simultaneously in the same frequency band. As a result, the W55RFS27T3B / W55RFS27R3C provide a simple remote control capability for multiple players with low cost and high performance.

In addition, the W55RFS27R3C accommodates a wide range of operating voltages (2.2 ~ 5.5 V) and supports 2- or 3-battery applications.

The associated transmitter W55RFS27T3B meets FCC/ETSI regulations for 27 MHz, 40 MHz, and 49MHz S-R (Super-regeneration) demodulation.
