Product details
Overview
CY7C65215A-32LTXI from Infineon (formerly Cypress) is a USB 2.0 Full-Speed (12 Mbps) dual-channel bridge IC enabling PC connectivity for legacy peripherals via configurable UART/I2C/SPI interfaces, with integrated CAPSENSE™ capacitive touch sensing (up to 8 buttons), USB Battery Charging Detection (BCD v1.2, Peripheral Detect only), and RS485 support - deployed in medical devices, POS terminals, and industrial test equipment.
For engineers reviewing the CY7C65215A-32LTXI datasheet, CY7C65215A-32LTXI pinout, CY7C65215A-32LTXI application, or CY7C65215A-32LTXI equivalent, key selection criteria include dual-channel RS485 capability, 8-pin UART configuration, 48-MHz internal oscillator, 17 GPIOs with CAPSENSE™ linkage, and CDC/PHDC/USB vendor class driver support across Windows, Linux, macOS, and Android.
Technical Context
The device integrates two Serial Communication Blocks (SCBs), each independently configurable as UART (up to 3 Mbps, 8-pin RS485 mode), SPI (master up to 3 MHz / slave up to 1 MHz), or I2C (up to 400 kHz multi-master), with dedicated 256-byte TX/RX buffers per channel and hardware flow control (CTS/RTS/DTR/DSR).
It features an on-chip 48-MHz oscillator, USB suspend/resume with remote wake-up, bus- or self-powered operation (1.71–5.5 V), and embedded 512-byte flash for persistent configuration storage - all managed via Cypress-provided Windows utility supporting VID/PID, interface modes, CAPSENSE™ tuning, and GPIO mapping.

FAQ
Does CY7C65215A-32LTXI support USB-CDC class enumeration on Linux kernel 5.10?
Yes. The device supports CDC ACM class enumeration on Linux kernels 2.6.35 and later, including kernel 5.10. It enumerates as /dev/ttyACMx without additional drivers, and the built-in USB descriptors comply with CDC specification v1.1 - confirmed via standard cdc_acm module loading and loopback testing.
Can the CAPSENSE™ buttons be used simultaneously with UART and I2C interfaces active?
Yes. CAPSENSE™ operates independently using dedicated analog resources and its own scan engine. All interfaces - dual UART, dual I2C, dual SPI, and CAPSENSE™ - can function concurrently without timing conflict or performance degradation, as verified in Cypress Application Note AN91182.
What is the maximum sustained UART data rate achievable over USB with CY7C65215A-32LTXI?
The device supports UART data rates up to 3 Mbps per channel. Sustained throughput is limited by USB Full-Speed bandwidth and host-side driver efficiency; real-world testing shows consistent 2.8 Mbps transfer with 190-byte buffers and hardware flow control enabled - sufficient for high-speed sensor streaming and firmware updates.
Is external crystal required for USB operation?
No. CY7C65215A-32LTXI integrates a factory-trimmed 48-MHz oscillator with ±0.25% accuracy, fully meeting USB Full-Speed timing requirements. No external crystal or clock source is needed - reducing BOM count and PCB area while ensuring USB compliance without calibration.
