• 8-bit single-chip microcontroller architecture.
• 2kbytes of flash program memory, 128 bytes of RAM.
• 4-channel 10-bit A/D converter for analog-to-digital conversion.
• 64MHz instruction execution (using dedicated clocks).
• Programmable and configurable peripheral functions.
• Enhanced instruction set for addressing and manipulating program memory, data memory, and interrupt operation.
• Integrated monitor, watch dog timer and UART.
• On-chip real-time clock.

Application Fields

The MB90F020CPMT-GS-9071 is ideal for applications in automotive control systems, home appliance control, general-purpose control, remote control systems, and other industrial control systems. It is particularly popular for applications that require a low power consumption and are cost-sensitive. The wide range of peripheral functions included in the MCU makes it useful for a variety of tasks such as motion control, temperature control and other monitoring functions.

Working Principle

The MB90F020CPMT-GS-9071 works on the principle of executing instructions written in an embedded programming language that is stored in its internal program-memory (2kbytes). The instructions can either be written by a user or can be included in the MCU as pre-programmed instructions, as is the case with the Freescale Semiconductor MB90F family of microcontrollers. The main components of the microcontroller are a Central Processing Unit (CPU), an input/output (I/O) module, an internal bus system, and memories.The CPU is responsible for executing instructions, reading and writing data from and to the memories, and controlling and monitoring the operations of the other components of the microcontroller. The I/O module provides the interface for communication with external devices, as well as for reading and writing data. The internal bus connects the CPU and I/O module with the memories and external devices. The memories can be either ROM or RAM, and can be used to store program instructions (ROM) or data (RAM).The MB90F020CPMT-GS-9071 can be programmed using any of the common programming languages, such as C, assembly language or machine language. The programming of the controller is done through the use of a special programming environment that allows the user to write and debug programs. Once the program has been written and debugged, it is transferred to the memory of the controller and can then be used to control the operation of the device.
