W55RFS27R3C DataSheet
2.2 W55RFS27R3C Functional Description
ChannelShared Protocol Engine
W55RFS27R3C+W55RFS27T3B built-in
ChannelShared^WB protocol enables maximum 3
players in a frequency band. Switch channel is
simply switch an input state, instead of change
crystal such a high cost channel switching.
RF Receiver
W55RFS27R3C RF receiver has been enhanced
from "Super-Regeneration" architecture for R/C toy
application. The high sensitivity and high noise
immunity property is very suitable for getting
higher RF receiving performance in very high noise
level environment.
On-chip LNA provides isolation from receivers and
is very useful for multi-player application
Power Regulator
W55RFS27R3C build-in on-chip power regulator
provides a stable operating performance under
operating voltage from 2.2V ~ 5.5V, the very wide
range of operating voltage is specially designed for
mini R/C toy or R/C vehicle by 2-battery or 3-
battery operation.
Baseband Control Function Decoder
W55RFS27R3C build-in 6-function of general
baseband control function for R/C toy "Forward";
"Backward"; "Left-turn"; "Right-turn", and 2 more
reserved control functions of "F1"; "F2".
