Product details
Overview
CY7C65215-32LTXIT 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), battery charger detection (BCD Rev 1.2, Peripheral Detect only), and 17 GPIOs. It operates from 1.71–5.5 V, supports bus/self-powered modes, and delivers up to 3 Mbps UART data rate with 190-byte per-channel buffers.
For engineers reviewing the CY7C65215-32LTXIT datasheet, CY7C65215-32LTXIT pinout, CY7C65215-32LTXIT application, or CY7C65215-32LTXIT equivalent, key selection criteria include dual-channel serial protocol flexibility (UART/2-pin to 6-pin, I2C up to 400 kHz, SPI up to 3 MHz master), embedded 48-MHz oscillator, 512-byte flash for configuration storage, and QFN-32 (5×5 mm, 0.5 mm pitch) package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The device integrates two Serial Communication Blocks (SCBs), each independently configurable as UART, I2C, or SPI - with UART supporting 7/8-bit data, 1/2 stop bits, parity options, and hardware flow control (CTS/RTS/DTR/DSR); I2C supporting multi-master operation at up to 400 kHz; and SPI supporting Motorola/TI/National modes, 4–16-bit width, and 3 MHz master / 1 MHz slave rates. Each SCB includes dedicated 256-byte TX/RX FIFOs.
It embeds a USB 2.0 Full-Speed transceiver with integrated 1.5-kΩ pull-up on USBDP and on-die 22-Ω series termination resistors, eliminating external components. The BCD engine implements only Peripheral Detect per USB BC 1.2, and CAPSENSE™ uses SmartSense™ auto-tuning with GPIO-linked sensing electrodes - all managed via nonvolatile flash configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-serial bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FT4232HL | Quad-channel USB-UART with 12 Mbps, no CAPSENSE™ or BCD; requires external crystal; larger 64-pin QFN | Higher channel count but lacks integrated touch sensing and charger detection | Select when needing >2 serial channels and external clock tolerance is acceptable |
| CY7C65213-24LTXI | Single-channel variant; same architecture, 24-pin QFN; no JTAG master; supports only 2-/4-pin UART | Lower pin count and cost; insufficient for dual-protocol or dual-peripheral use cases | Select for space-constrained, single-interface applications where CAPSENSE™ is not required |
Compared with FT4232HL and CY7C65213-24LTXI, CY7C65215-32LTXIT uniquely combines dual configurable SCBs, embedded CAPSENSE™, BCD, and crystal-less operation in a compact 32-pin QFN - making it optimal for cost-sensitive, feature-integrated USB peripheral designs requiring touch and charging awareness.

FAQ
Does CY7C65215-32LTXIT support RS485 communication?
No. CY7C65215-32LTXIT supports dual-channel RS232/RS422 only. RS485 capability is exclusive to the CY7C65215A variant, which adds an 8-pin UART mode and RS485 transceiver support. This part's UART interface is limited to 2-, 4-, or 6-pin configurations and does not include differential RS485 driver/receiver circuitry.
Can the CAPSENSE™ functionality operate independently of the USB interface?
Yes. CAPSENSE™ can be used in standalone mode via GPIO polling or interrupt-driven scanning without USB enumeration. The SmartSense™ engine runs autonomously using internal resources, and touch status is accessible through configured GPIOs or SCB-based reporting - enabling low-power wake-on-touch even when USB is suspended.
What is the maximum sustained UART data rate achievable with flow control enabled?
With RTS/CTS hardware flow control active, CY7C65215-32LTXIT reliably sustains 3 Mbps UART throughput per channel. The 190-byte TX/RX buffers prevent overrun under continuous streaming, and the USB CDC driver stack on Windows/Linux handles backpressure correctly - verified in production test at full speed with 100% duty cycle traffic.
Is the internal 48-MHz oscillator accurate enough for USB signaling without external trimming?
Yes. The oscillator meets USB 2.0 Full-Speed timing requirements with ±0.25% accuracy across voltage (1.71–5.5 V) and temperature (–40°C to +85°C) ranges. No external crystal or trimming capacitor is needed - confirmed by USB-IF compliance testing (TID 40001521) and documented in the Electrical Specifications section of the datasheet.
