CY8CTMG200A-16LGXI

Application Specific Microcontrollers Overview

The CY8CTMG200A-16LGXI is a PSoC 1 microcontroller from Cypress Semiconductor, featuring an M8C CPU core and TrueTouch capacitive sensing capabilities. It integrates 32 KB of Flash memory and operates within a voltage range of 1.71 V to 5.5 V. The device utilizes a 16-pin LQFP package (16LGXI suffix). Key system resources include a Full-Speed USB interface, I2C slave controller, SPI module, programmable timers, and GPIOs. The architecture supports sleep modes with watchdog functionality and includes internal oscillators (IMO, ILO) alongside external crystal support.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '16LGXI' corresponds to the 16-pin LQFP package variant. Confirm that the 'A' designation aligns with the intended temperature or revision requirements as specified in the official datasheet. Ensure compatibility with the PSoC Designer development environment for firmware implementation.

Application Specific Microcontrollers Selection Notes

Select this component when a combined MCU and capacitive touch controller are required in a single package. The 16-pin form factor suits space-constrained designs. Verify that the M8C instruction set and available peripherals (USB, I2C, SPI) meet the application's communication needs without requiring additional external chips.

Application Specific Microcontrollers Part Context

This part belongs to the PSoC 1 family, specifically the CY8CTMG20x series which combines general-purpose microcontroller functions with TrueTouch sensing. It shares architectural similarities with the CY8CTST200 series but is optimized for integrated touch solutions. The device is documented in Technical Reference Manual 001-53603.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same package may include other variants from the CY8CTMG20x or CY8CTST200 families, such as the CY8CTMG200-16LGXI or CY8CTST200-16LGXI, provided functional differences in Flash size or peripheral availability are acceptable.
