Cortex-M4 vs. Cortex-M3: The N32G457RCL7 features an ARM Cortex-M4 core with FPU, enabling faster floating-point calculations and DSP operations compared to the older Cortex-M3 in STM32F107.
144 MHz vs. 72 MHz: Double the clock speed for real-time control and high-performance applications.
512 KB Flash vs. 128/256 KB: More code space for complex firmware.
144 KB SRAM vs. 64 KB: Better handling of large data buffers and multitasking.
Faster & More ADCs: 4* 12-bit ADCs (4.7 Msps) vs. two slower ADCs (1 Msps) in STM32F107.
Dual DAC Support: Unlike STM32F107 (no DAC), the N32G457RCL7 includes two 12-bit DACs for precision analog output.
Enhanced Timers: 17 timers (incl. 32-bit) vs. 10 timers (mostly 16-bit) in STM32F107, improving PWM and motor control capabilities.
Dual CAN 2.0B: Supports two CAN buses (vs. one in STM32F107), ideal for automotive and industrial networks.
USB OTG: Unlike STM32F107 (USB FS only), it supports USB OTG for host/device flexibility.
Integrated Ethernet MAC+PHY: Unlike STM32F107 (MAC only), it includes an on-chip PHY, reducing BOM cost.
Built-in cryptographic acceleration for secure communication, absent in STM32F107.
1.8V - 3.6V operation (vs. 2.0V min in STM32F107), improving battery efficiency.
Ultra-low-power modes extend battery life in portable applications.
The N32G457RCL7 is ideal for:
Industrial Automation (PLC, motor control)
Automotive Electronics (CAN networks, diagnostics)
IoT & Smart Devices (secure communication, sensor hubs)
Consumer Electronics (HMI, audio processing)
The N32G457RCL7 outperforms the STM32F107 series in processing power, memory, analog precision, connectivity, and security, while maintaining cost competitiveness(Cost savings 50–60% vs. STM32). Its Cortex-M4 core, dual CAN, USB OTG, Ethernet MAC+PHY, and hardware encryption make it a future-proof upgrade for embedded designs.
