CY8CTMG100-32LKXI

Application Specific Microcontrollers Overview

The CY8CTMG100-32LKXI is a TrueTouch™ capacitive touchscreen controller designed for single-touch and multi-touch applications. It supports up to 25 X/Y sensor inputs and typical screen sizes of 4.7 inches or smaller, achieving fast scan rates of approximately 300 µs per sensor. The device integrates an M8C processor running at speeds up to 12 MHz with 8 KB Flash and 512 bytes SRAM. Operating on a 2.4V to 5.25V supply, it delivers low power consumption, averaging 1.9 mA at an 8 ms report rate. Communication is handled via I2C (1.8V support) and SPI interfaces within an industrial temperature range of –40°C to +85°C.
