Frequently Asked Questions
What is the active and sleep current consumption of STM32L452CCU6TR at 48 MHz and how does it compare in Stop 2 mode?
At 48 MHz with all peripherals active the STM32L452 typically consumes around 3.4 mA from a 3.3 V supply, translating to roughly 71 µA per MHz. In Stop 2 ultra-low-power mode current drops to approximately 110 nA with RAM retention, extending coin-cell battery life to several years in periodic sensing applications.
Which cryptographic accelerators does STM32L452CCU6TR integrate and what key lengths are supported?
The STM32L452 integrates a hardware AES accelerator supporting 128-bit and 256-bit key lengths for CBC, ECB, CTR, and GCM modes. This hardware engine offloads encryption from the Cortex-M4 core, enabling AES-128 throughput of over 150 Mbps without impacting real-time control tasks running in parallel on the same device.
For a compact wearable sensor design, how many analog and digital peripherals does STM32L452CCU6TR provide?
The device provides a 12-bit ADC with up to 16 channels at 5.33 Msps, 1 DAC channel, 2 operational amplifiers, 3 UARTs, 3 SPI, 2 I2C, 1 USB 2.0 Full-Speed, and 12-channel DMA. This peripheral mix supports simultaneous analog sensor acquisition, digital communication, and USB data logging without any external interface ICs.
