Description

Technical Field

[0001] This utility model relates to the field of MCU chip technology, specifically to a programming interface extension structure for MCU chips. Background Technology

[0002] MCUs achieve low power consumption through optimized design, making them particularly suitable for battery-powered edge devices such as smartwatches and wireless sensors. At the same time, they cover the intelligent needs of low computing power scenarios at a cost close to that of traditional MCUs. Compared with high-end MPUs or FPGAs, they can reduce costs by 5-10 times. After integrating AI algorithms, MCU chips can complete tasks such as image recognition and fault detection locally, with response speeds improved to millisecond levels. They can still work normally in offline environments. For example, smart home cameras can achieve real-time intrusion detection, and industrial sensors can complete real-time monitoring of arc signals. The programming interface of MCU chips usually refers to GPIO ports, which are the key channels for data exchange between the chip and external devices. They mainly realize functions such as input / output control, level conversion, and interrupt handling.

[0003] However, traditional MCU chips have the following drawbacks:
