M487 Ethernet Series

M487 Ethernet Series

The 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 the up to 160 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® M487 Ethernet series supports operating voltage from 1.8V to 3.6V, and industrial operating temperature from - 40°C to 105°C. It is equipped with 10/100 Mbps Ethernet MAC with RMII and hardware cryptography engine. Package type includes LQFP64, LQFP128 and LQFP144.
