| Description |
The Nuvoton 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. |
| Features |
