MFID & RF Family

Part No. W55RFS27R3C
Datasheet N/A
Description The Nuvoton W55RFS27R3C is a fully integrated, S-R (Super-regeneration) RF receiver with full-function 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 Nuvoton-patented 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 49 MHz S-R (Super-regeneration) demodulation.
Features
  • Nuvoton patented ChannelSharedWB protocol enables a maximum of three players simultaneously in one frequency band.
  • On-chip LNA provides better isolation so that receivers can work together without interference.
  • Enhanced receiver circuit provides higher sensitivity than traditional super-regenerative circuits.
  • Operating frequencies: 27 MHz to 49 MHz (depending on the oscillator frequency)
  • Operating voltages: 2.2 V ~ 5.5 V
  • (uC-mode) Receiving data rates up to 2.5 Kbps for 50% duty cycle signals
  • (manual-mode) R/C-toy baseband control command decoder, supporting 6 functions; Forward, Backward, Left-turn, Right-turn, and 2 user-defined functions F1 and F2
  • (manual-mode) Frequency hopping increases receiver sensitivity
  • Power-down current consumption less than 1 μA
  • Associated transmitter W55RFS27T3B is compliant with FCC part 15 Subpart C 15.227 / ETSI 300 220-1 low-power and short-range device requirements
  • Operating temperature: 0oC ~ 70oC
