CY8CTST200-32LQXI

Application Specific Microcontrollers Overview

The CY8CTST200-32LQXI is a TrueTouch single-touch touchscreen controller from the PSoC CY8CTMG20x and CY8CTST200 family. It integrates an M8C CPU core with supervisory ROM (SROM) for flash management functions such as block read, write, erase, and protection. The device includes a TrueTouch module supporting multiple sensing approaches including positive charge integration, relaxation oscillator, successive approximation, negative charge integration, and sigma delta. System resources include I2C slave, SPI, programmable timers, and full-speed USB interfaces.
