MA803 is a single-chip microprocessor based on 80C51 high-efficiency 1-T structure, each instruction requires 1~7 clock signals (6~7 times faster than standard 8051), and is compatible with 8051 instruction set. Therefore, with the same processing power as the standard 8051, the MA803 only needs to run at a very low speed, thereby reducing power consumption to a great extent.
MA803 has 15.5K bytes of built-in Flash memory for saving code and data. Flash memory can be programmed through in-system (ISP). At the same time, in-application programming (IAP) capabilities are also provided. ISP allows users to download new code without removing the microcontroller from the product; IAP means that the microcontroller can write non-volatile data in Flash while the application is running. These functions are provided by the built-in charge pump to provide high voltage for programming.
