AK37E

The AK37E series processors are designed for applications such as building intercom indoor units, central control panels, and human-machine interaction (HMI) display devices. Based on the ARM926EJ-S core, the processors incorporate a DVP interface, video and audio codecs, and a display controller, facilitating efficient processing of multimedia data and enhancing the visual and interactive capabilities of the HMI. The processors also integrate a comprehensive set of peripheral interfaces, including TWI, UART, SPI, MMC/SD/SDIO, and USB 2.0, supporting flexible peripheral configuration and improving overall product scalability for diverse application needs.
