8-bit MCU are widely used in various fields such as industrial control, intelligent interface, instrumentation, etc. due to their strong functions. 8-bit single-chip microcomputers still occupy the mainstream position in medium and small-scale applications. Plays an increasingly important role.
Cmsemicon has currently completed a chip development platform with MCU as the core, achieving structured and modular development of chips. It has 8-bit and 32-bit MCUs and can respond quickly to different sub fields. The 8-bit microcontroller platform of Zhongwei Semiconductor is based on the high-performance 8-bit reduced instruction set core and 8051 core. The product resources mainly involve AD, touch, operational amplifiers, LED/LCD, and provide optimized analog and digital peripherals, flexible pin mapping, and high system clock frequency.
