EFM32PG23 Microcontroller for IoT applications

29 June 2022 DSP, Micros & Memory

Silicon Labs’ EFM32PG23 microcontroller is the ideal combination of security, precision analog capabilities, and excellent low-power performance. That collection of features makes it a great fit for many IoT applications, especially those powered by batteries. The EFM32PG23 comes in fine pitch QFN packages that make the 40-pin version the same size as standard 32-pin QFN at 5 x 5 mm.

The PG23 has an Arm Cortex-M33 that can run at a frequency up to 80 MHz with only 21 µA/MHz operating current. In sleep mode, the PG23 consumes as little as 1,03 µA. These efficiencies, combined with LESENSE, make the PG23 extremely well suited to battery-powered applications. The microcontroller has up to 512 kB of flash and up to 64 kB of RAM. In addition to the standard communication protocols, the PG23 has an LCD controller, a keypad scanner and a die temperature sensor. It has two analog comparators and an analog-to-digital converter with selectable resolution allowing 12-, 16-, or 20-bit conversion.

The small size and rich feature set make it an excellent fit for high-volume edge applications in industrial and consumer applications such as smart meters, solar inverters, smoke detectors, smart locks, lighting controls or any other application where precision monitoring is required.
