Product details
Overview
CY8CTST200-48LTXI 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, configurable analog and digital blocks, 16 KB flash, 2 KB SRAM, and 48-pin TQFP package. It supports I²C, SPI, USB 2.0 Full-Speed, and programmable timers for embedded human-interface applications.
For engineers reviewing the CY8CTST200-48LTXI datasheet, CY8CTST200-48LTXI pinout, CY8CTST200-48LTXI application, or CY8CTST200-48LTXI equivalent, this part is selected for touch-enabled industrial HMI, consumer control panels, and low-power embedded systems requiring integrated analog front-end and firmware-configurable logic.
Technical Context
The CY8CTST200-48LTXI implements a dedicated TrueTouch sensing engine with built-in capacitive sensing hardware, including analog multiplexers, comparators, and sigma-delta modulators optimized for mutual- and self-capacitance measurement. Its M8C CPU runs at up to 24 MHz with 24-bit instruction word width and Harvard architecture.
System-level resources include four programmable digital clock dividers, dual I²C slave interfaces (one supporting SMBus), full-speed USB PHY with endpoint buffers, and a 16-channel GPIO matrix supporting drive modes (CMOS, open-drain, high-Z, resistive pull-up/down) with individual slew-rate and current-drive control.

FAQ
What is the maximum operating temperature for CY8CTST200-48LTXI?
The CY8CTST200-48LTXI is rated for industrial temperature range: −40°C to +85°C. Its internal regulators, TrueTouch sensing circuitry, and flash memory are characterized and guaranteed across this range. The device meets JEDEC JESD22-A108F reliability testing for extended thermal cycling and storage life under these conditions.
Does CY8CTST200-48LTXI support USB device enumeration without external components?
Yes. The part integrates a full-speed USB 2.0 PHY with internal 1.5 kΩ pull-up resistor on D+, on-chip termination, and endpoint buffer memory. When configured as a USB device, it enumerates as HID, CDC, or vendor class using only the onboard crystal (ECO) and standard USB cable-no external transceiver, resistors, or magnetics required.
Can the TrueTouch subsystem operate independently of the M8C CPU?
Yes. The TrueTouch hardware engine runs autonomous scan sequences using its own sequencer and RAM buffers. The CPU can enter deep sleep while touch scanning continues, waking only on threshold breach or completion interrupt. Baseline tracking and noise filtering are handled in hardware, reducing CPU load by >70% versus software-only implementations.
Is flash programming supported in-system via SWD or JTAG?
No. CY8CTST200-48LTXI uses Cypress's proprietary ISSP (In-System Serial Programming) interface via P1[0]/P1[1] (USB_DP/USB_DM) or P2[4] (reset) and VDD/VSS. Debugging and programming require Cypress-provided MiniProg3 or KitProg programmers-not standard SWD/JTAG tools. Firmware updates can be delivered over USB or I²C using bootloader firmware.
