Features and Specifications

The MB9AFA42NBBGL-GE1 is made with an 8-bit 70MHz CPU, which is fast enough for most small applications. It has enough flash memory to store up to 32KB of instructions and data. This microcontroller also has 2KB of RAM for data and instructions, along with 32 bytes of EEPROM for program storage. There are also 2 independent 16-bit channels for analog/digital conversion, and a 10-bit A/D converter for analog input.

Other features include 16-bit PWMs, 4-channel 16-bit timers, and 2 serial interfaces with full-duplex UARTs. On the housing, there are 12 input/output lines, as well as two external interrupt inputs. The microcontroller is powered by a 5V voltage source, with a wide operating temperature of up to 105-degrees celsius.

Working Principle

The MB9AFA42NBBGL-GE1 works in the same manner as most embedded microcontrollers. The core of the processor is composed of the CPU and a set of control registers. The CPU executes instructions and manipulates data under the control of the microprograms, and is responsible for storing data in and retrieving data from the registers. When a signal is sent to the microcontroller, it reads the register’s content and adjusts its behavior accordingly.

Each of the microcontroller’s components work together to make sure that the processor executes the instructions from the microprogram correctly. The flash memory is capable of storing the instructions, the RAM is responsible for storing data, and the EEPROM stores the microprograms. The A/D converter is used for analog data conversion and the 16-bit channels are used for digital data conversion. The PWM, timers, and UART are all used for different types of communication within the microcontroller.
