Overview
Description
Built on STM32L4+ architecture, it excels in power efficiency, supporting multiple low-power modes (down to 4 nA in shutdown). It includes hardware AES encryption and CRC for security.
Available in a 48-pin UFQFPN package, it’s ideal for battery-powered IoT, wearables, and embedded applications requiring performance and energy savings.
Key features:
- Core: Cortex-M4 (with FPU)
- Memory: 256 KB Flash, 64 KB SRAM
- Power: 1.71–3.6V, ultra-low-power modes
- Peripherals: USB, ADC, DAC, timers, AES
- Package: UFQFPN48 (7x7 mm)
Suitable for portable, low-power designs needing robust processing.
Equivalent
- STM32L432KCU6: Similar features, fewer GPIOs.
- STM32L443CCU6: Adds AES encryption.
- STM32L433CCU7: Same specs, different package.
- STM32L452CCU6: Higher performance, more peripherals.
- STM32L412KBU6: Lower cost, reduced memory.
