Overview
Description
- Core: 170 MHz Cortex-M4 (with FPU)
- Memory: 512 KB Flash, 128 KB SRAM
- Peripherals: Rich set including 5x USARTs, 4x SPIs, 4x I²Cs, 3x ADCs (16-bit), 2x DACs, and 7x timers.
- Analog: High-resolution ADCs/DACs for precision applications.
- Connectivity: USB 2.0 FS/HS, CAN FD.
- Packaging: 64-pin LQFP.
Ideal for industrial control, IoT, and embedded systems requiring high-speed processing and analog precision. Low-power modes enhance energy efficiency.
Equivalent
- STM32G491CET6: Same core but in LQFP-48 package.
- STM32G491VET6: Larger flash (512KB) in LQFP-100.
- STM32G471RET6: Similar but with fewer peripherals.
- STM32F303RET6: Older F3 series, lacks some G4 features.
For pin-to-pin replacements, consider STM32G431RET6 (lower flash) or STM32G491REY6 (WLCSP package). Always verify specs for your application.
