The CY8C4126LTI-M445 is a 64-pin 32-bit ARM Cortex-M4 microcontroller and is a member of Cypress Microcontroller Division’s PSoC 4 family. This microcontroller is specifically designed for applications requiring exceptional, low latency analog and digital signal processing performance. Applications of this device span automotive, medical, industrial, consumer, and wearables, just to name a few.

CY8C4126LTI-M445 has two main building blocks, an ARM Cortex-M4 processor and a multi-SLM peripheral controller. The Cortex-M4 processor is a 32-bit ARM® Cortex™ M4 MCU with an integrated floating-point unit, running up to 48 MHz, 32 Kbytes of SRAM, and 1 Mbyte of integrated Flash memory for code storage. The peripheral controller is a multi-SLM (System Level Memory) architecture module which tightly integrates resources such as Ports and DMA into the device. The module also has a highly configurable logic fabric which allows the device to be configured for various use cases.

The main purpose of the CY8C4126LTI-M445 is aside from its ability to provide a high-performance execution capacity, allowing it to be used in tasks such as motor control, image sensing, and analog signal processing, it is also able to efficiently handle system level tasks such as power management and connectivity. The device is able to achieve this thanks to its deep level of integration, and its ability to integrate multiple system resources on a single device, making it ideal for applications that require low latency, low cost, and/or a low footprint.

The main purpose of the Cortex-M4 processor is to provide high-performance computing. The processor features a high-speed dual-core architecture with two separate bus masters with shared and distinct queues, and a fast floating-point unit for efficient and powerful algebraic operations. The processor also contains an instruction cache, a data-side cache, and an instruction byte-code cache. The data-side cache provides fast access to instructions from memory and peripherals, reducing the number of instruction cache reads. The two bus masters are functionally divided into one for accessing memory, and one for handling peripheral operations.

The peripheral controller in the CY8C4126LTI-M445 is a multi-SLM peripheral controller. This is a highly integrated single-chip memory controller which provides support for a wide variety of peripherals, including UART, I2C, SPI, USB, CAN, and Ethernet. The peripheral controller supports multiple serial communication protocols, allowing the microcontroller to talk to a variety of different external devices. The peripheral controller also has a logic fabric which supports multiple simultaneous slave transactions and provides a low-latency, high-throughput interface for embedded applications.

The CY8C4126LTI-M445 also includes an integrated multipurpose timer, an analog-to-digital converter (ADC) for analog input, and a universal digital interface (UDI) for hooking up external hardware with ease. The ADC can be used for a variety of measurements, such as temperature, pressure, and force, and the UDI can be used to directly connect to external hardware, like sensors and actuators. The device also contains a low-power ULP (ultra-low power) co-processor which helps ensure safe operation in low-power applications.

Overall, the CY8C4126LTI-M445 is an excellent choice for applications which require low latency operation and very low power consumption. Its combination of high-performance processing and system resources allows it to be used in a variety of highly demanding use cases.
