Product details
Overview
EFM32PG28B210F1024IM68-AR from Silicon Labs is a 32-bit ARM Cortex-M33 microcontroller operating at up to 80 MHz, featuring 1024 kB flash, 256 kB RAM, Secure Vault High security, and 51 GPIO - optimized for battery-powered industrial automation and portable medical devices requiring ultra-low-power operation down to 1.1 µA in EM2 Deep Sleep mode.
For engineers reviewing the EFM32PG28B210F1024IM68-AR datasheet, EFM32PG28B210F1024IM68-AR pinout, EFM32PG28B210F1024IM68-AR application, or EFM32PG28B210F1024IM68-AR equivalent, this page delivers verified specifications, QFN68 package mapping, energy-mode current values, IADC resolution options (12/16/20-bit), and secure boot architecture details critical for low-energy embedded design validation.
Technical Context
The EFM32PG28B210F1024IM68-AR implements ARM TrustZone for hardware-isolated secure execution and integrates a dedicated Secure Engine with DPA countermeasures, TRNG, PUF-based key management, and ECDSA/ECDH support across NIST P-192/P-256/P-384/P-521 and Curve25519 curves. Its energy management unit supports five energy modes (EM0–EM4) with sub-µA retention in EM2 using LFRCO.
It features a 12-channel Peripheral Reflex System (PRS) enabling autonomous peripheral interaction without CPU wake-up, plus an AI/ML-capable Matrix Vector Processor (MVP) - though MVP is excluded in this variant ('f2=0' per ordering code key). The IADC supports Normal mode only (no High-Speed/High-Accuracy), and LCD controller is present but not enabled in this part number.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EFM32PG28B310F1024IM68-A | Includes IADC High-Speed/High-Accuracy modes and Matrix Vector Processor (MVP); same flash/RAM/security/package | Required for real-time audio preprocessing or high-speed sensor fusion where >1 Msps sampling or vector math acceleration is needed | Select when MVP or 2 Msps IADC is essential; otherwise EFM32PG28B210F1024IM68-AR offers identical security and power efficiency at lower cost |
| EFM32PG23B210F1024IM68-A | Same feature set but Series 2 PG23 family; lacks Secure Vault High (only Mid), no Curve25519/Ed25519, reduced crypto algorithm support | Suitable for cost-sensitive consumer IoT where NIST-only crypto and basic secure boot suffice | Choose only if Secure Vault High features (PUF, attestation, tamper detect) are unnecessary; EFM32PG28B210F1024IM68-AR provides full industrial-grade security |
Compared with EFM32PG28B310F1024IM68-A, the EFM32PG28B210F1024IM68-AR removes MVP and IADC advanced modes - reducing die size and cost while retaining identical Secure Vault High, memory, and ultra-low-power performance.
