M482ZGCAE

The NuMicro® M482 USB FS OTG series is a high performance, low power microcontroller powered by the Arm® Cortex®-M4F core with DSP extension. Running up to 192 MHz with 130 µA/ MHz dynamic power consumption provides excellent energy efficiency. The 256 KB embedded Flash memory supports up to 4 configurable eXecute-Only-Memory regions, and the 128 KB embedded SRAM provides multi-level retention in standby power-down mode. The factory pre-loaded bootloader delivers Secure Boot functionality to check code integrity inside embedded Flash memory. One-Time Programmable ROM is also included for product life-cycle management.

The NuMicro® M482 USB OTG series supports operating voltage from 1.8V to 3.6V , and industrial operating temperature from - 40 ℃ to 105 ℃ . It is integrated with camera interface, 12-bit 5 MSPS ADC , USB full speed OTG with the crystal-less feature in device mode, and up to eight sets of high-speed UART interface. Package type includes QFN33, LQFP48, LQFP64, and LQFP128.
