Product details
Overview
EFM32PG1B200F256IM48-C0R from Silicon Labs is a 32-bit ARM Cortex-M4 microcontroller operating at up to 40 MHz with DSP extensions and FPU, featuring 256 kB flash, 32 kB RAM, integrated DC-DC converter, hardware AES/ECC/SHA crypto engine, and ultra-low energy modes including 0.58 μA EM4H hibernate with 128-byte RAM retention. It targets battery-powered IoT sensors and industrial edge nodes requiring secure, long-life operation.
For engineers reviewing the EFM32PG1B200F256IM48-C0R datasheet, EFM32PG1B200F256IM48-C0R pinout, EFM32PG1B200F256IM48-C0R application, or EFM32PG1B200F256IM48-C0R equivalent, key selection criteria include EM4H current draw, CRYOTIMER wake-up capability in hibernate, DC-DC efficiency at 200 mA load, 5 V-tolerant I/O compatibility, and PRS-enabled autonomous peripheral coordination without CPU wake-up.
Technical Context
The EFM32PG1B200F256IM48-C0R implements a flexible energy management architecture with five defined energy modes (EM0–EM4), where EM4H retains 128 bytes of RAM at 0.58 μA and supports CRYOTIMER wake-up via LFXO/LFRCO/ULFRCO. Its Peripheral Reflex System (PRS) enables hardware-triggered signal routing between 12-channel peripherals-including TIMER, RTCC, LETIMER, and ACMP-without CPU intervention.
It integrates dual oscillators (HFXO up to 40 MHz, LFXO 32.768 kHz) plus six internal RC sources (HFRCO, AUXHFRCO, LFRCO, ULFRCO), all managed by the Clock Management Unit (CMU) for dynamic clock gating. The crypto accelerator supports AES-128/256, NIST P-192/P-256/ECC-K163, and SHA-224/256 with DMA-triggered operation and GCM/CCM mode acceleration.
