Operating at frequencies up to 80 MHz, it provides 512 KB of Flash memory and 160 KB of SRAM. The device features an integrated USB Type-C and Power Delivery PHY, making it ideal for USB-C adapter and charger designs. With CAN-FD support, 12-bit 5 MSPS ADC, and hardware AES-256 encryption, it addresses the needs of secure IoT, industrial, and consumer applications.","working_principle":"The STM32L452RET6 is built on ST's ultra-low-power platform, featuring adaptive voltage scaling and multiple low-power modes including Sleep, Stop, Standby, and Shutdown. The Cortex-M4F core executes single-cycle DSP instructions and hardware floating-point operations for efficient signal processing. The integrated USB Type-C\/PD PHY handles CC line detection and BMC signaling for Power Delivery negotiations without external components. The CAN-FD controller supports flexible data-rate frames up to 8 MBd. The ADC employs a 12-bit SAR architecture with hardware oversampling up to 256x for enhanced resolution without CPU intervention.","pin_description":"\n
