Product details
Overview
CY7C65215A-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 sensing, battery charger detection (BCD v1.2), and RS485 support - used in medical devices, POS terminals, and industrial test equipment.
For engineers reviewing the CY7C65215A-32LTXIT datasheet, CY7C65215A-32LTXIT pinout, CY7C65215A-32LTXIT application, or CY7C65215A-32LTXIT equivalent, key selection criteria include dual-channel RS485 capability, 8-pin UART configuration, 48-MHz internal oscillator, 17 GPIOs with CAPSENSE™ linkage, and BCD-compliant peripheral detection without host negotiation.
Technical Context
The device integrates two Serial Communication Blocks (SCBs), each independently configurable as UART (up to 3 Mbps, 8-pin mode), SPI (master up to 3 MHz / slave up to 1 MHz), or I2C (up to 400 kHz), with dedicated 256-byte TX/RX buffers per channel and support for multi-master I2C and Motorola/TI/National SPI modes.
It embeds a USB 2.0 Full-Speed transceiver with integrated 1.5-kΩ USBDP pull-up and termination resistors, a 48-MHz internal oscillator, 32-kHz low-power oscillator, voltage regulator, and 512-byte flash memory for persistent configuration storage - all operating across 1.71–5.5 V supply and –40°C to +85°C industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-serial bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65215-32LTXI | Lacks RS485 support and 8-pin UART mode; no JTAG master; includes JTAG instead of CAPSENSE™ | Suitable for cost-sensitive dual-UART-only designs without touch interface or industrial serial requirements | Select when RS485 and CAPSENSE™ are unnecessary and JTAG programming of external MCUs is required |
| FT4232HL | Quad-channel USB-to-serial (UART/FIFO); no CAPSENSE™, BCD, or RS485; requires external crystal | Better suited for high-throughput FIFO-based data acquisition where multiple independent streams are needed | Choose when needing four independent UARTs or synchronous FIFO interfaces, not capacitive sensing or charger detection |
Compared with CY7C65215-32LTXI, CY7C65215A-32LTXIT adds RS485 and CAPSENSE™ at the expense of JTAG, while FT4232HL offers higher channel count but lacks integrated sensing, charging detection, and clocking - making CY7C65215A optimal for embedded touch+industrial serial edge nodes.

FAQ
Does CY7C65215A-32LTXIT require an external crystal?
No. It integrates a factory-trimmed 48-MHz oscillator and a 32-kHz low-power oscillator, eliminating the need for external crystals or clock sources in most USB and CAPSENSE™ applications. Only optional external clocks are supported for specialized timing requirements.
Can both UART channels operate simultaneously in RS485 mode?
Yes. Each UART channel (SCB0 and SCB1) can be independently configured for RS485 half-duplex operation using GPIO-controlled direction control, enabling dual isolated RS485 buses without external transceivers or logic.
How is the unique serial number implemented and accessed?
The unique 128-bit serial number is factory-programmed into one-time-programmable (OTP) memory and bound to the CDC device descriptor. It is automatically applied during enumeration, ensuring consistent COM port assignment in Windows without driver modification or registry edits.
What is the maximum sustained data rate across both UART channels?
Each UART channel supports up to 3 Mbps individually. When both channels operate concurrently, aggregate throughput is limited by USB Full-Speed bandwidth (12 Mbps theoretical, ~10 Mbps practical), allowing sustained combined rates up to ~9 Mbps with proper buffer management and host-side buffering.
