DESCRIPTION
APC240 is a ultra low power sub-1 GHz transceiver module designed for operations in the
unlicensed ISM (Industrial Scientific Medical) and LPRD bands based on RFIC SX1212 from
SEMTECH. FSK (Frequency Shift Keying) modulation/demodulation, multi-channel operation,
high bandwidth efficiency and anti-blocking performance make APC240 modules easy to realize
the robust and reliable wireless link.
The module can be configured to work in different channels with 200KHz space. It adopts high
efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up
to 3dB which keeps in advance in error correction and coding efficiency over normal FEC
(Forward Error Correction) coding. Because of its high reliability in correction, modules can filter
error and fake information automatically and realize truly transparent wireless link, which makes
APC240 very suitable in the rigid communication environment.

APC240 integrates two 256 bytes buffer. When the buffer is empty, users can transfer nearly 217
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 fa ster than UART data rate (MCU to RF module).
APC240 provides standard UART/TTL interface. Users can choose seven data rates and three
parity checks which make APC240 possibly tailor-made for different applications. APC240
operates at 2.1~3.6V with extra low power consumption. The
