EFM32PG23 Microcontroller

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 (5 mm x 5 mm). The small size and rich features set make it an excellent fit for high volume edge applications in industrial and consumer applications. The EFM32PG23 has already been designed into applications as varied as smart meters, solar inverters, smoke detectors, smart locks, and lighting controls.

The PG23 has an Arm® Cortex®-M33 that can run up to 80 MHz with only 21 µA/MHz operating current. In sleep mode, the PG23 can get to just 1.03 µA. These efficiencies, combined with LESENSE, make the PG23 work extremely well in battery-powered applications. There is plenty of memory for most algorithms with up to 512 kB of Flash and up to 64 kB of RAM. In addition to a good collection of serial communication peripherals, the PG23 has an LCD controller, a keypad scanner, and a die temperature sensor. The PG23 has two analog comparators and an analog-to-digital converter (ADC) with flexible resolution allowing 12-bit, 16-bit, or 20-bit output to sense signals at the edge.
