What is the difference between HC32L and HC32F series?

HDSC HC32 series differentiation: (1) HC32L (Ultra-Low Power) - optimized for battery life with sub-μA standby, lower clock speeds (4-48MHz), rich analog peripherals, LCD drivers, best for IoT/wearables; (2) HC32F (General-Purpose) - optimized for performance with higher clock speeds (up to 240MHz), more processing power, advanced peripherals, best for industrial/complex applications; (3) Power - HC32L: 0.5μA standby, HC32F: 1-2μA standby; (4) Core - HC32L: Cortex-M0+, HC32F: Cortex-M0+ or M4; (5) Flash - HC32L: up to 128KB, HC32F: up to 512KB; (6) Price - HC32L lower cost, HC32F higher performance. Choose HC32L for battery life, HC32F for processing power.

Choose HC32L for battery-powered IoT. Choose HC32F for industrial/complex processing. Contact FAE for guidance.
