FSK (Frequency Shift Keying) modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make RF1212 modules easy to realize the robust and reliable wireless link. The module can be configured to work in different channels with 200 KHz space. It adopts high efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up to 3d B which keeps in advance in error correction and coding efficiency over normal FEC (Forward Error Correction) - 1 - 2011-10-12 RF1212 coding. Because of its high reliability in correction, modules can filter error and fake information automatically and realize truly transparent wireless link, which makes RF1212 very suitable in the rigid munication environment. RF1212 integrates two 256 bytes buffer. When the buffer is empty, users can transfer 256 bytes data per time and even limitless data transfer can be achieved as long as RF data rate (RF module to RF module) is configured to be faster than UART data rate (MCU to RF module). RF1212 provides standard UART/TTL interface for selection. Users can choose seven data rates and three parity checks which make RF1212 possibly tailor-made for different applications. RF1212 operates at 2.1~3.6V with extra low power consumption. The current in polling mode can be minimized to 20u A and the current in receive mode no more than 4m A makes modules very suitable for battery powered-up applications. Pin...
