C8051F861-C-ISR

The C8051F861-C-ISR is a microcontroller with a built-in timer, a total of 3 serial ports and an interrupt controller. Its application field focuses on embedded microcontrollers where it works in sectors like automotive, industrial automation, consumer electronics, medical applications, security and much more. Its working principle involves the use of interrupt vectors and and a variety of interrupts.

The C8051F861-C-ISR microcontroller is capable of handling up to 25 interrupt sources and taking appropriate actions depending on the priority of the interrupt. It also has the capability of working with both level-sensitive interrupt requests as well as external interrupts which makes it ideal for use in embedded microcontrollers applications.

The interrupts are dispatched by the CPU to the interrupt controller, which then sets the priority levels for the individual interrupt sources. The CPU begins to prioritize the interrupts based on the level set by the interrupt controller and then passes the interrupt request to the appropriate device that is connected to the microcontroller.

The interrupt controller on the C8051F861-C-ISR microcontroller is capable of setting up to five different interrupt levels. It is also able to respond to the presence of an interrupt vector in the program memory, which allows the MCU to dispatch an interrupt request to a specific device. In this way, the C8051F861-C-ISR can simultaneously handle multiple peripheral devices and can be used in a variety of applications.

In short, the C8051F861-C-ISR is a reliable and powerful microcontroller with an impressive array of features. It can be used in various embedded applications due to its ability to handle high level interrupts, manage the priority levels of its associated peripheral devices, and respond to interrupt vectors. It is an ideal choice for use in automotive, industrial automation, consumer electronics, medical applications, security and much more.
