EZR32HG220F64R67G-B0

RF Transceiver ICS Overview

The EZR32HG220F64R67G-B0 is an RF transceiver and microcontroller unit (MCU) from Silicon Labs' EZR32HG series. It integrates an ARM Cortex-M0+ core with 64 kB of flash memory and 8 kB of RAM, operating at a maximum clock frequency of 25 MHz. The device supports wireless communication protocols including IEEE 802.15.4 and proprietary EZRadio standards across a frequency range of 142 MHz to 1.05 GHz. It features a 12-bit ADC with six channels, multiple serial interfaces such as I2C, SPI, and UART, and offers up to 27 general-purpose input/output pins. Packaged in a 48-VFQFN exposed pad, it operates within a temperature range of -40°C to +85°C.

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'B0' against the manufacturer's current product status documentation, as component availability and lifecycle stages may vary. Confirm that the 48-VFQFN package dimensions and pinout align with your PCB layout requirements. Ensure compliance with RoHS directives and moisture sensitivity level (MSL) handling procedures during assembly. Cross-reference the datasheet revision history to confirm compatibility with existing firmware libraries and development tools.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF transceiver solution is required for sub-GHz applications. It is suitable for designs needing moderate processing power alongside wireless capabilities. Consider the 25 MHz clock speed and 64 kB memory limits for application complexity. Evaluate the 1.98 V to 3.8 V supply voltage range against system power constraints. Compare pin counts and peripheral availability against alternative models in the EZR32 family if more GPIOs or different radio features are needed.

RF Transceiver ICS Part Context
