EFR32FG1V131F128GM32-C0R is a high-performance radio frequency (RF) transceiver IC designed to enable the rapid development of wireless products in the Sub-1GHz ISM/SRD frequency bands. It integrates the protocol stack functions into its onboard processor, and the configurable receiver block and transmitter are connected directly to the antenna, thus enabling the realization of a highly integrated RF sub-system in compact form factor.

The chip is designed to operate in the 30 MHz - 110 MHz frequency bands, and can transmit at up to 20 dBm RF output power. It also supports rate shifting and CRC for data management. Moreover, its low-power consumption and functional versatility makes it an ideal choice for several long-range applications, such as smart meters, automatic meter reading, industrial and gateway applications.

The EFR32FG1V131F128GM32-C0R is based on a 32-bit ARM Cortex-M4 processor core and is equipped with 128KB of embedded flash memory. The chip has a wide range of integrated peripherals, such as port timers, ADC, PPD module, encryption support, PWM, UARTs, SPI and I2C. It also has dedicated RAM and a dedicated register set, allowing users to develop their own firmware for the device.

The device has several peripheral functional blocks, such as the 12-bit ADC for measuring analog signals, two independent PPD controllers to manage external components, and the IRQ line to manage interrupts. The chip also supports two serial ports and a single-chip I2C interface for connecting with external peripherals, as well as an SPI slave and master interface.

The most important aspect of the EFR32FG1V131F128GM32-C0R is its highly efficient RF transceiver, which is based on an integrated low-power radio architecture. The transceiver supports both peak and average power measurement and is compliant with multiple standards, including the European Telecommunications Standards Institute (ETSI) 300-220 Tip 8, EN 300 320, EN 301 489-3, and many others. The stand-alone transceiver employs an easy-to-use interface and provides an optimal solution for wireless communications in the low-power bands.

The EFR32FG1V131F128GM32-C0R supports both frequency hopping and direct sequencing, thus enabling the long-range communication necessary for multiple applications. The integrated synthesizer supports a wide range of frequencies and can be tuned to match the exact frequency band needed for a given application. The receiver is able to detect narrowband and wideband signals, and the output of the receiver is adjustable to help reduce the receive sensitivity.

The EFR32FG1V131F128GM32-C0R is a versatile and powerful RF transceiver IC, with a wide range of applications. Its integrated radio architecture, low-power consumption, and flexible interface make it an ideal choice for smart meters, automatic meter reading, industrial and gateway applications, as well as other long-range wireless applications.
