Nuvoton M485 NuMicro® Crypto Series Microcontrollers

Nuvoton M485 NuMicro® Crypto Series Microcontrollers (MCUs) are low-power MCUs powered by the Arm® Cortex®-M4F core with DSP extension. These MCUs are capable of running up to 192MHz with 175μA/MHz dynamic low power consumption. The M485 MCUs are embedded with a hardware cryptography engine and dual USB HS/FS OTG. These MCUs feature 512KB zero-wait state Flash memory and 160KB RAM, including 32KB external SPI Flash cache. The M485 MCUs include 80 bytes of battery-powered backup registers and a 16-channel peripheral DMA controller. These MCUs are available in LQFP48, LQFP64, and LQFP128 packages. The M485 MCUs are used in fingerprint modules, smart payments, secure IoT devices, and secure USB device applications.
