MKL36Z256VMC4 is an embedded microcontroller from NXP Semiconductors, previously known as Freescale Semiconductor. This energy-efficient and cost-effective device delivers high performance while providing an extensive set of features, optimum peripherals and flexible memory resources.

MKL36Z256VMC4 is based on the ARM Cortex-M0+ processor and utilizes a 16-bit wide bus architecture. It provides 48KB of programmable Flash memory, 4KB of SRAM, and 1024 bytes of EEPROM. Additionally, the MKL36Z256VMC4 contains several peripheral modules such as 3-axis digital accelerometer, real-time clock module, watch dog timer, debug logic, USB controller, DMA controller, and Ethernet controller.

The MKL36Z256VMC4 is suitable for a wide range of applications, such as consumer electronics, healthcare, industrial control systems, and transportation. It also finds applications in automotive applications, as well as in communication infrastructure and personal entertainment products.

The working principle of MKL36Z256VMC4 is relatively simple. Its core is a Cortex-M0+ processor that is used to execute instructions and both program and data memory for storing program data. The processor communicates with other peripherals, such as the memory, timers, I/O ports, and interrupts, over a bus. The processor can be dynamically reconfigured to change the clock speed and various other configurations through the Power Management Unit (PMU).

The Cortex-M0+ processor uses a three-stage pipeline to process instructions and data. The three stages are instruction fetch, instruction decode, and execution. The processor fetches instructions from the program memory and decodes them, then executes the instructions. The instructions are also processed in order, so instructions will be executed in the order they were fetched. The processor also uses a dedicated processor core, allowing for a wide range of instruction sizes and complexity.

Data is transferred between the processor and other peripherals over the bus. The bus is a shared communication system that is used to connect the processor to all other peripherals. The bus consists of an address bus for sending and receiving address information and a data bus for sending and receiving data. The bus is controlled by the processor core, which issues signals to tell the bus what it needs. The bus also has several control signals, such as selects and reads that tell the peripheral what is being requested and when to respond.

All peripherals are connected to the processor via an interrupt controller. The interrupt controller is responsible for managing interrupts from all peripherals and notifying the processor when an interrupt occurs. Each peripheral can be assigned a priority level, and the interrupt controller will prioritize and issue the appropriate signal to the processor when an interrupt occurs.

In addition to the processor core, the PMU is used to control the clock frequency and configure various power management settings. The PMU can be configured to change the clock frequency and other parameters, allowing the processor to operate at various levels of power efficiency. The PMU also monitors the peripherals, allowing the processor to transition to different power modes when a certain level of activity is detected.

MKL36Z256VMC4 is an embedded microcontroller that is suitable for a wide range of applications in consumer electronics, healthcare, industrial control systems, and transportation. It features a Cortex-M0+ processor, an extensive set of features and peripherals, as well as flexible memory resources. It communicates with other peripherals via a bus, with an interrupt controller to manage interrupts, and a PMU for power management. By utilizing these features, the MKL36Z256VMC4 can provide high performance at a low cost.
