Charakteristische Applikationen

The NuMicro® M484 USB HS OTG series is a high performance, low power microcontroller powered by the Arm® Cortex®-M4F core with DSP extension. It can run up to 192 MHz with 175 µA/MHz dynamic low power consumption. The 512/ 256 KB embedded dual bank Flash memory supports OTA (Over-The-Air) firmware upgrade, and the 160/ 96 KB embedded SRAM includes 32 KB cache to speed up external SPI Flash code execution. The factory pre-loaded bootloader delivers Secure Boot functionality to provide the code integrity check in embedded Flash memory. The built-in Secure Protection ROM provides a safe space for saving confidential program or data. One-Time Programmable ROM is also included for product life-cycle management.

The NuMicro® M484 USB HS OTG series supports operating voltage from 1.8V to 3.6V, and industrial operating temperature from -40°C to 105°C. It is integrated with 2 sets of USB 2.0 interface with op-chip full speed and high speed OTG PHY. Package type includes LQFP64 and LQFP128.

Target Application:
USB Adapter, USB Sensor Hub, etc.
