Frequently Asked Questions
What is the maximum CPU frequency and power supply range for STM32L462CET6P?
The STM32L462CET6P runs its Arm Cortex-M4 core at up to 80 MHz and operates from a supply voltage of 1.71 V to 3.6 V, making it well suited for both battery-powered and regulated 3.3 V systems.
How much non-volatile storage does STM32L462CET6P provide, and does it include hardware encryption?
It integrates 512 KB of Flash memory and 160 KB of SRAM, plus a dedicated AES-256 hardware accelerator for on-chip encryption, removing the need for an external crypto IC in secure IoT designs.
Which low-power standby mode draws the least current on STM32L462CET6P?
In Stop 2 mode the STM32L462CET6P draws only about 2.3 µA with RAM retention active, extending coin-cell battery life to months or years in sensor nodes that wake briefly every few minutes.
For a USB-connected data logger design, what USB capability does STM32L462CET6P offer?
The device provides a full-speed USB 2.0 Device interface supporting up to 8 bidirectional endpoints, enabling CDC virtual-COM, HID, or mass-storage class implementation without an external USB bridge chip.
