The M487JIDAE 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 KB embedded dual bank Flash memory supports OTA (Over-The-Air) firmware upgrade, and the 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 M487JIDAE 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 is LQFP144.
