Product Overview
The CIU32L051K8U6TR is a high-performance, ultra-low-power secure 32-bit microcontroller from Huada Electronics, featuring an ARM Cortex-M0+ core operating at up to 48MHz. Packaged in compact QFN32 with tape and reel packaging for automated SMT production, this MCU integrates segment LCD driver, hardware AES encryption and true random number generator (TRNG).
Optimized for long-life battery-powered devices, it supports a wide 1.8V–5.5V operating voltage and industrial-grade temperature tolerance. With rich peripheral interfaces and excellent power consumption control, it is a high-cost-performance replacement for imported low-power MCUs, widely used in smart metering, smart home, portable devices and low-power IoT terminals.
