DRF7020D13 is a low-cost sub-1 GHz transceiver module designed for operations in the unlicensed ISM (Industrial Scientific Medical) and LPRD bands. GFSK (Frequency Shift Keying) modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make DRF7020D13 modules easy to realize the robust and reliable wireless link.
Features:
* GFSK transceiver Module
* 433Mhz ISM frequency band
* 19.2K bps FSK data rate
* Multiple channels
* 13dBm Max. output power
* Baud rate configurable
* 256 bytes data buffer
* Standby current < 5uA
* Supply voltage 3.4~5.5V
Application:
Home automation,
Security alarm,
Telemetry,
Automatic meter reading,
Contactless access,
Wireless data logger,
Remote motor control
The module can be configured to work in different channels with 200k Hz space. It adopts high efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up to 3dB which keeps in advance in EDAC and coding efficiency over normal FEC (Forward Error Correction). Because of its high reliability in correction, modules can filter error and fake information automatically and realize truly transparent wireless link, which makes DRF7020D13 very suitable in the rigid communication environment.
DRF7020D13 integrates 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). The module provides standard UART/TTL interface for selection. Users can choose seven data rates and three parity checks which make DRF7020D13 possibly tailor-made for different applications. DRF7020D13 operates at 3.3~5.5V with extra low standby current which makes it suitable for battery powered-up applications.
