CY8CTST200A-24LQXIT

Application Specific Microcontrollers Overview

The CY8CTST200A-24LQXIT is a TrueTouch single-touch touchscreen controller from the Cypress PSoC family. It integrates an M8C CPU core, TrueTouch sensing module, and system resources including I2C, SPI, and USB interfaces. The device operates within a voltage range of 1.71 V to 5.5 V and features 32 KB of Flash memory. It supports multiple oscillator sources such as IMO, ILO, and ECO, along with GPIO, comparators, and programmable timers for flexible peripheral configuration.

Application Specific Microcontrollers Feature Summary

• Integrated TrueTouch sensing module supporting positive charge integration, relaxation oscillator, successive approximation, negative charge integration, and sigma delta approaches.
• Built-in M8C CPU core with supervisory ROM (SROM) functions for block read, write, erase, and protection.
• Comprehensive communication interfaces including I2C Slave (EZI2C mode), SPI, and Full-Speed USB.
• Flexible clocking options with Internal Main Oscillator (IMO), Internal Low Speed Oscillator (ILO), and External Crystal Oscillator (ECO).

Application Specific Microcontrollers Applications

• Single-touch capacitive touchscreen applications in portable devices.
• Human-machine interface (HMI) controllers requiring low power consumption.
• Embedded systems utilizing integrated USB or I2C connectivity for sensor data acquisition.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '24LQXIT' against official Cypress documentation to confirm package type (QFN-24) and temperature grade. Ensure compatibility with existing firmware libraries designed for the CY8CTST200 series. Check for end-of-life status or alternative recommendations from Infineon Technologies, which acquired Cypress Semiconductor.

Application Specific Microcontrollers Selection Notes

Select this component when a dedicated single-touch controller with integrated processing capabilities is required. Compare pin counts and interface availability against other variants like CY8CTST200-16LGXI or CY8CTST200-32LQXI based on available GPIOs and communication needs. Consider the 1.71 V to 5.5 V operating range for power supply design flexibility.

Application Specific Microcontrollers Part Context

This part belongs to the PSoC CY8CTMG20x/CY8CTST200 family, documented in Technical Reference Manual 001-53603. The 'A' suffix typically denotes a revision or variant within the CY8CTST200 series. The device combines analog sensing front-end with digital processing, reducing external component count compared to discrete solutions.

Application Specific Microcontrollers Replacement Considerations

Check for direct substitutes within the CY8CTST200 family with different pin counts or packages. Verify if newer generations from Infineon offer pin-compatible or functionally equivalent alternatives with updated feature sets.
