MA803AS2 is a 80C51-based high-performance 1-T structure of single-chip microprocessors, each instruction requires 1 to 7 clock signals (8051 than the standard fast 6 to 7 times), compatible with the 8051 instruction set. So in the standard 8051 has the same processing capacity of the case, MA803 only need very low operating speed, and thus can greatly reduce the power consumption.
The MA803 has 15.5K bytes of built-in flash memory for code and data. Flash memory can be programmed in-system (ISP). At the same time, it also provides in-application programming (IAP) capabilities. 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 programmed by the built-in charge pump to provide high voltage.
Port 1 is an 8-bit bidirectional I/O port with internal pull-ups and can be used as inputs. Port 1 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 1 pins that are externally pulled low will source current because of the internal pull-ups. P1.0 is also used as one of event sources for timer2, or output carrier of timer2, alias T2. P1.1 is also used as one of interrupt-controlling sources for timer2, alias T2EX.
MA803AS2 retains the basic features of the standard 80C52: 512 bytes of random access memory, 23 I / O ports, two external interrupts, and two timer / counters. A PCA timer, an SPI interface, a one-time-enabled watchdog WDT, a 10-bit ADC, a low-level reconnaissance LVD, an enhanced multiprocessor communication and improved speed universal string Line port (EUART).
The MA803 has two power-saving modes to reduce power consumption. In Idle mode, the CPU is frozen and the peripheral module and interrupt system remain active. In Power-down mode, the contents of RAM and Special Function Registers (SFRs) are saved and all other functions are terminated. Most importantly, the microcontroller in power-down mode can be woken up by an external interrupt.
Port 3 is an 8-bit bidirectional I/O port with internal pull-ups and can be used as inputs. Port 3 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are externally pulled low will source current because of the internal pull-ups. Port3 also serves other special functions of this device. P3.0 and P3.1 act as receiver and transceiver of the data for UART function block, Alias RXD and TXD. P3.2 and P3.3 also act as external interrupt sources, alias INT0 and INT1. P3.4 and P3.5 also act as event sources for timer0 and timer1 individually, alias T0 and T1. P3.6 also acts as write signal while access to external memory, alias /WR. P3.7 also acts as read signal while access to external memory, alias /RD.
