EFR32 SOC Arm Cortex 4 & High Sensitivity DSSS Transceiver Module is coming soon

Dear customers:

In March 2021, NiceRF launched a new SOC Arm Cortex 4 & High Sensitivity DSSS Transceiver Module EFR32.

The EFR32 module is developed based on SILICON’s EFR32FG14 Flex Gecko chip. It uses DSSS modulation and high-efficiency receiving sensitivity, making its penetration capability and communication distance far beyond the current FSK and GFSK products. EFR32FG14 is a 32-bit ARM®Cortex®-M4 core chip with ultra-high-speed wake-up time, integrated scalable power amplifier and wireless transceiver, maximum operating frequency of 40MHz, 128 KB of flash memory and 16 KB of running memory.

The EFR32 module uses a wireless transceiver and MCU two-in-one chip, Silabs privde library for RF operation, which greatly accelerates the development progress. NiceRF provide the demo kit and demo code for this module.

• 2 watchdog timers
• 16 general-purpose I/O pins
• 128K bytes Flash memory
• 16K bytes RAM memory
• 2 UART standard communication interface
• 1 LPUART low-power communication interface
• Working temperature range: -40℃~+85℃
• 1.8V-3.8V power supply
• Integrated power amplifier, the highest transmit power is 22.9 dBm (Sub-GHz)
• Supports multiple transmission protocols such as DSSS, GFSK, OOK, MSK, etc.

Application：

• Home and building automation and security
