DATADSHEET
The NuMicro® M483 CAN 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® M483 CAN series supports operating voltage from 1.8V to 3.6V, and industrial operating temperature from -40°C to 105°C. It is integrated with two or three sets of CAN 2.0B interface, dual 12-bit 5 MSPS ADC, camera interface, 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 LQFP64 and LQFP128.
Target Application:
Motor Control, Industrial Control, Battery Management System, EV Charging Pile, etc.
