STM32L4A6ZGT6 – TEXAS INSTRUMENTS

The STM32L4A6ZGT6 is a low-power ARM Cortex-M4F microcontroller from STMicroelectronics, featuring a 64MHz CPU with FPU and a 256KB Flash memory, 64KB SRAM. Crucially, it integrates a 12-bit ADC with 16 channels, crucial for high-resolution analog signal acquisition, and offers a wide range of communication interfaces including USB 2.0 Full-Speed, SPI, I2C, and UART. Operating from a 1.71V to 3.6V supply voltage, its ultra-low-power modes (down to 20µA in Stop mode) make it ideal for battery-powered applications. Packaged in a 64-pin LQFP, it’s physically compact, facilitating high-density board design. Its advanced security features, including a crypto accelerator and tamper detection, are particularly beneficial for IoT and security-sensitive applications. Common use cases include wearable devices requiring precise sensor data acquisition, smart home automation hubs demanding low-power consumption, and industrial control systems needing robust communication and processing capabilities. The STM32L4A6ZGT6’s balance of processing power, analog capabilities, low-power consumption, and security features makes it a strong contender where these aspects are critical design considerations.
