CY8C24423A-24PVXA Application Field and Working Principle

The CY8C24423A-24PVXA is a modern 8-bit microcontroller designed and manufactured by Cypress Semiconductor. It is part of the PSoC 4L family and is intended to be used in embedded applications specifically requiring low-cost, low-power operation and industry-leading design features. This device features an extensive selection of peripheral and system resources, including an LCD Controller. As an 8-bit device, it can be used in a variety of applications due to its multiplexing capabilities and advanced core features.

Application Fields

The CY8C24423A-24PVXA is ideal for applications that require direct interfacing with LCD modules as well as other features including pulse-width modulation (PWM) and bidirectional serial communication with other devices. It can also be used in applications such as automotive, lighting control, embedded gaming, Motor Control, and many others. The LCD Controller feature allows for easy interface with LCD displays, providing the ability to display up to 16 characters or graphics.

Power Modes

The CY8C24423A-24PVXA device has four different power modes: Sleep, On, Deep Sleep, and Low Power. The Sleep mode disables the clock source to the system and the device is put into a low power state. The On mode enables the system clock and allows for normal operation. Deep Sleep mode is the same as Sleep but allows for a complete power-off until it is woken up as well as saving more power than Sleep. Low Power mode turns off selected parts of the system to reduce power consumption.

Power Efficiency

The CY8C24423A-24PVXA is designed to operate with low power consumption. It offers a Cyclic Redundancy Check (CRC) feature for error checking, which can detect and recover from errors on the bus or in the system. The clock tree includes integrated pre-programmed options that can help achieve low power system performance. The chip also includes a 32kHz oscillator allowing for peripheral operation when the main clock is stopped.

Clock and Interrupts

The CY8C24423A-24PVXA includes an internal system clock. This clock can be configured to run between 100kHz and 8MHz, allowing hardware to operate at different speeds. The device features an interrupt controller that can detect an interrupt signal from a peripheral and signal the processor to take appropriate action. There are also eight interrupt pins that can be used to connect external circuitry.

Wrapping up

Overall, the CY8C24423A-24PVXA is a low cost, low power microcontroller that is designed for embedded applications. It has plenty of features and peripherals to interface with, including an LCD display controller and interrupt pins. The device has four different power modes and can handle a range of clock speeds from 100kHz to 8MHz. Its design allows for efficient power management with minimal power consumption and error checking features.
