Image of Nuvoton NuMicro® M487 Series Microcontrollers Nuvoton’s NuMicro M487 Ethernet 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. Up to 2.5 MB Flash memory and up to 160 kB embedded SRAM include 32 kB cache to speed up external SPI Flash code execution. The factory preloaded 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 programs or data. One-time programmable ROM is also included for product life-cycle management.

The NuMicro M487 Ethernet series supports operating voltage from 1.8 V to 3.6 V and industrial operating temperature from -40°C to +105°C. It is equipped with 10/100 Mbps Ethernet MAC with RMII and a hardware cryptography engine. The package type includes LQFP64, LQFP128, and LQFP144.
