Application field of MB91F267APMC-GE1

The MB91F267APMC-GE1 is commonly used in embedded applications due to its wide range of peripheral capabilities and its ability to interface with other devices. It is suitable for use in automotive, industrial, and consumer electronics, as well as in home appliances, point-of-sale systems, and medical equipment. Its low power consumption makes it a suitable choice for battery powered applications. The MB91F267APMC-GE1 is also used for applications such as motor control and display control.

Working principle of MB91F267APMC-GE1

The MB91F267APMC-GE1 operates on a modified Harvard architecture, which differs from the Von Neumann architecture in that it separates memory and the bus into two distinct paths. Similarly, the device is organized into functional blocks and memory mapped I/O locations. In the MB91F267APMC-GE1, the program memory space holds both the user program and preprogrammed resources such as MAC, EEPROM, Real-Time-Clock, and the LCD controller. Data memory space is divided into two sections: the general data memory and special function registers (SFR). The SFRs hold important control and status information such as I/O port configurations, interrupt enable, and flag status. The MB91F267APMC-GE1 supports a wide range of I/O peripherals, such as UART, USB, SSI, I2C, Serial Peripheral Interface (SPI), I/O ports, A/D converter and more.
