CY8C20336A-24LQXI application field and working principle

Introduction

CY8C20336A-24LQXI is an application-specific microcontroller (MCU) for the embedded market. It is based on Cypress Semiconductor Corporation’s PSoC 5LP family of products, and is the smallest, lowest-cost, and highest-performance MCU in the family. This MCU combines a powerful all-digital PSoC 5LP architecture based on a Arm® Cortex™-M3 and digital peripherals, as well as full-speed USB 2.0 and CAN 2.0B protocol support. The purpose of this article is to discuss the application field and working principle of CY8C20336A-24LQXI.

Application Field

CY8C20336A-24LQXI is an ideal MCU for cost-sensitive industrial and consumer applications where real-time performance, small size, and low power consumption are key requirements. This MCU excels in functionality and cost, providing more functionality and features while carrying a very competitive price tag. The 32‑bit power of the Arm Cortex–M3 makes this a versatile and efficient platform for a wide range of embedded applications and systems. At the heart of this MCU lies a 32‑bit, 100‑MHz Arm Cortex–M3 CPU with 32-KB Flash memory, 4‑KB Battery RAM, and 248‑KB SRAM. This helps minimize cost and reduce system development times. CY8C20336A-24LQXI also supports up to three serial port channels, 50 programmable digital signal blocks, analog blocks, and more, providing a high degree of flexibility for embedded design.CY8C20336A-24LQXI is a reliable solution for applications such as human-machine interfaces, general-purpose logic controllers, lighting control, data link bridge, real-time displays, factory automation, industrial automation, and medical instrumentation.

Working Principle

The core of CY8C20336A-24LQXI is a 32‑bit Arm Cortex™-M3 processor. This processor is designed to allow the MCU to quickly and efficiently execute instructions, process data, and control peripherals. When the processor receives an instruction, it begins by breaking it down into smaller commands known as microinstructions. These microinstructions are the ones that are actually sent to the ALU, where they are divided into even smaller operations known as naninstructions, which the ALU can directly process.CY8C20336A-24LQXI\'s hardware peripherals are toggled on and off by the CPU over the control bus. The digital signal blocks also respond to commands from the CPU over the control bus. They can be configured for analog-to-digital and digital-to-analog conversions, pulse-width modulation outputs, pulse counter/timers, serial communications protocols such as SPI and UART, and other digital signal processing capabilities.In addition, CY8C20336A-24LQXI supports the USB 2.0 high-speed and the CAN 2.0B standards. With the USB 2.0 high-speed protocol, the MCU can support data transfer rates up to 480 Mbps. The CAN 2.0B protocol allows for data transfer rates up to 1 Mbps. Both protocols allow for efficient and reliable data communications.

Conclusion

CY8C20336A-24LQXI is a versatile and cost-effective MCU solution that is ideal for a wide range of industrial and consumer applications. It features a powerful 32‑bit Arm Cortex™-M3 processor and a variety of hardware peripherals and digital signal blocks for enhanced flexibility and performance. In addition, it supports the USB 2.0 high-speed and CAN 2.0B protocols for reliable and efficient data communications. With its compact size and low power consumption, CY8C20336A-24LQXI is the perfect solution for cost-sensitive and low-power applications.
