Embedded - Microprocessors:

The MIMXRT1021CAF4A microprocessor is a 32-bit high performance, low-power ARM Cortex-M7-based device designed for embedded applications. It comes with 2MB of high-speed cache memory and a wide array of integrated peripherals for a range of applications including industrial automation, consumer, and medical sector.

The MIMXRT1021CAF4A is targeted at embedded designs such as digital signal processing, industrial control, factory automation, consumer electronics, smart home appliances, medical instruments, and HMI supplement. It offers a wide range of features such as a dual-core system, an advanced vector unit, on-chip functional safety, and a secure boot system.

As compared to its predecessors, the MIMXRT1021CAF4A is more energy efficient and offers advanced features such as a 32-bits high-performance CPU with an ARM v7 architecture and an ARM Cortex-M7 core frequency of 528 MHz. Its Floating Point Unit supports a combination of single and double-precision operations. The dual-core system supports both single-core and multi-core operation, including symmetric multiprocessing and Asymmetric Messaging Passing.

The MIMXRT1021CAF4A includes multiple peripheral functions, such as a USB 2.0 High Speed host controller, a CAN bus controller, UART, I2C, PWM, and GPIOs on the main chip. For developing applications, it provides a range of high-performance development tools, such as the NXP MCU Expandable Software Development Platform (ESDP), and Kinetis Design Studio (KDS) that can help jump start the platform setup, store, and debug processes.

Developers can take advantage of the advanced security features available on the MIMXRT1021CAF4A, such as a Secure Boot System that helps protect the integrity of the boot code from attacks and tampering launching from outside the device. Furthermore, it provides functional safety capabilities that helps embedded applications comply with safety standards such as MISRA, IEC61508, ISO26262 and SIL3.

At the heart of the MIMXRT1021CAF4A is its working principle, which is based on a hardware-based boot process sequence. This process includes the Power-On Reset (or POR) signal, which is generated when power is applied to the device, and Trigger signal sent to the microprocessor, which in turn executes the boot code written in the embedded flash, before the core is released to execute the application code.

Once the application code is executed, the microprocessor can perform several different tasks, including data processing, system monitoring, communication, and control. To allow multiple tasks to be executed in parallel, the microprocessor can have several interrupt lines connected to its interrupt controller. This allows the microprocessor to monitor the status of external devices without actively monitoring them.

The MIMXRT1021CAF4A is a highly efficient and versatile embedded processor that offers a host of advanced features for a range of embedded applications. With its low power consumption, wide array of features and secure boot and functional safety features, the MIMXRT1021CAF4A makes an ideal choice for embedded system designs.
