Product details
Overview
CY8CTMG200-16LGXI from Cypress Semiconductor is a programmable mixed-signal PSoC (Programmable System-on-Chip) device integrating an M8C 8-bit CPU core, TrueTouch capacitive sensing subsystem, I²C slave interface, full-speed USB 2.0 PHY, and configurable analog/digital peripherals. It features 16 KB flash, 2 KB SRAM, operates at up to 24 MHz, and supports capacitive touch button/slider/wheel interfaces in space-constrained consumer electronics.
For engineers reviewing the CY8CTMG200-16LGXI datasheet, CY8CTMG200-16LGXI pinout, CY8CTMG200-16LGXI application, or CY8CTMG200-16LGXI equivalent, this device is selected for embedded touch control where integrated USB connectivity, low-power sleep modes, and on-chip analog signal conditioning reduce BOM count and PCB footprint.
Technical Context
The CY8CTMG200-16LGXI implements a single-cycle M8C CPU core with Harvard architecture, 24 MHz internal main oscillator (IMO), and dual-clock domain operation supporting simultaneous USB (48 MHz) and system (24 MHz) timing. It integrates a dedicated TrueTouch sensing engine with hardware-accelerated baseline tracking and noise rejection.
Its analog subsystem includes a 12-bit SAR ADC, programmable gain amplifier (PGA), comparators, and an I/O analog multiplexer enabling flexible sensor front-end configuration. Digital resources include four 8-bit programmable timers, SPI/I²C/UART serial interfaces, and GPIOs with configurable drive strength and slew rate.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable touch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C20x34-16LQXI | Same M8C core, 8 KB flash, no USB PHY; uses external USB transceiver. | Lacks integrated USB-requires additional IC and layout area for USB connectivity. | Select when USB is not required or when legacy design reuse prioritizes cost over integration. |
| MTCH6302-I/ST | Dedicated capacitive touch controller (no CPU), I²C-only interface, 16-channel sensing. | No programmable logic or USB-relies entirely on host MCU for processing and communication. | Select when touch functionality is isolated and host MCU handles all protocol and UI logic. |
Compared with CY8C20x34-16LQXI and MTCH6302-I/ST, CY8CTMG200-16LGXI uniquely combines USB 2.0 PHY, TrueTouch engine, and user-programmable M8C core in a 16-pin QFN-enabling standalone HID device implementation without external components or host dependency.

FAQ
Does CY8CTMG200-16LGXI support USB device enumeration without external components?
Yes. The device integrates a full-speed USB 2.0 PHY with internal 1.5 kΩ pull-up resistor on USB_DP, enabling direct connection to a USB Type-A receptacle. No external transceiver, resistors, or crystals are required for basic HID enumeration and data transfer.
What is the maximum number of independent capacitive sensors supported?
The CY8CTMG200-16LGXI supports up to 16 capacitive sensing channels via its TrueTouch engine. All GPIO pins (P0[0]–P0[5]) can serve as sense electrodes, and additional channels may be enabled using shared analog routing-subject to layout and mutual capacitance constraints.
Can the M8C core execute code from RAM?
No. The M8C core executes instructions exclusively from flash memory. RAM is used for data storage only. Code execution from RAM is not supported due to Harvard architecture restrictions and lack of instruction fetch path from SRAM.
Is there hardware support for I²C master mode?
No. The I²C peripheral in CY8CTMG200-16LGXI operates in slave mode only. It cannot initiate transactions or act as a bus master. Host communication must be initiated by an external master device, such as a microcontroller or SoC.
