The M484SIDAE 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 ?A/ 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 M484SIDAE supports operating voltage from 1.8V to 3.6V, and industrial operating temperature from - 40 ℃ to 105 ℃ . It is integrated with 2 sets of USB 2.0 interface with op-chip full speed and high speed OTG PHY. Package type is LQFP64.
