Microcontrollers Procurement Notes

Verify the specific ordering code against the manufacturer's datasheet to ensure correct memory size and package configuration. Confirm that the component meets RoHS compliance requirements for your region. Check for any Not Recommended for New Design (NRND) status updates from Silicon Labs before finalizing procurement plans.

Microcontrollers Selection Notes

Select this model when a compact BGA48 footprint is required alongside 32 kB of program memory. It is suitable for applications needing high analog integration, such as capacitive sensing via LESENSE, or secure data transmission using hardware AES. Ensure design constraints accommodate the 1.98 V to 3.8 V supply range and industrial temperature specifications.

Microcontrollers Part Context

This component belongs to the EFM32TG Tiny Gecko series, designed for energy-sensitive embedded applications. It shares the ARM Cortex-M3 architecture with other Gecko families but offers lower memory capacities and smaller package options like QFN and BGA variants. The family emphasizes low-power performance and peripheral integration for battery-operated devices.

Microcontrollers Replacement Considerations

Consult the official ordering information table for direct pin-compatible alternatives within the EFM32TG family, such as EFM32TG225F16-D-BGA48 or EFM32TG225F8-D-BGA48, which share the same BGA48 package and feature set but differ in Flash and RAM sizes.

Microcontrollers FAQ

What is the sleep current consumption with RTC running?

The device consumes 1.0 μA in Deep Sleep Mode (EM2) with the Real-Time Counter (RTC) running, including RAM and CPU retention.

Does the EFM32TG225F32 support USB connectivity?

No, the EFM32TG Tiny Gecko family does not include USB peripherals. It supports USART, SPI, I2C, and Low Energy UART interfaces instead.

What is the resolution of the integrated ADC?

The Analog-to-Digital Converter (ADC) has a resolution of up to 12 bits and can achieve sampling rates up to 1 Msamples/s.
