Product details
Overview
CY7C65213A-32LTXIT from Cypress Semiconductor is a USB 2.0 Full-Speed (12 Mbps) USB-to-UART bridge controller supporting RS232/RS422/RS485 interface translation, 3 Mbps UART data rate, 256-byte TX/RX buffers, and integrated 48-MHz oscillator - deployed in industrial test equipment, POS terminals, and battery-operated medical devices like blood glucose meters.
For engineers reviewing the CY7C65213A-32LTXIT datasheet, CY7C65213A-32LTXIT pinout, CY7C65213A-32LTXIT application, or CY7C65213A-32LTXIT equivalent, key selection criteria include RS485 support (vs. CY7C65213), BCD-compliant peripheral detection, GPIO-configurable LED signaling, VCCIO voltage flexibility (1.71–5.50 V), and flash-programmable VID/PID/serial number for COM port stability.
Technical Context
The device integrates a USB 2.0 Full-Speed Serial Interface Engine (SIE), single-channel UART with hardware flow control (RTS#/CTS#, DTR#/DSR#), and dual internal oscillators (48 MHz for USB/UART, 32 kHz for suspend timing). It implements CDC, PHDC, and vendor-class USB device enumeration without external crystal or termination resistors.
Its 512-byte flash stores immutable USB descriptors and GPIO configurations; the unique serial number feature ensures persistent COM port assignment across reconnections. UART supports 7/8-bit data, 1/2 stop bits, five parity modes, break detection, and error reporting (parity, framing, overrun) - all configurable via Windows utility or Linux libcyusbserial API.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-Speed (12 Mbps); certified per USB-IF TID 40860041 - ensures host interoperability without custom driver stack. |
| UART Max Data Rate | 3 Mbps; enables high-throughput legacy peripheral bridging (e.g., industrial PLCs, barcode scanners). |
| Buffer Size | 256 bytes TX + 256 bytes RX; prevents data loss during USB host latency spikes in embedded host polling. |
| Operating Voltage | 1.71–5.50 V VCCIO; supports direct interfacing to 1.8 V, 3.3 V, or 5 V logic without level shifters. |
| Temperature Range | –40 °C to +85 °C (industrial grade); validated for deployment in uncontrolled environments like factory floors. |
| ESD Protection | 2.2-kV HBM; meets IEC 61000-4-2 Level 2 for robustness in handheld and field-deployed devices. |
| Package | 32-pin QFN (5 × 5 × 1 mm, 0.5-mm pitch); enables compact PCB layout with thermal pad for sustained UART throughput. |
Pinout & Package
32-pin QFN package (5 × 5 × 1 mm, 0.5-mm pitch) with exposed thermal pad; RoHS-compliant, industrial-grade construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCIO | I/O Supply Voltage | Configurable logic-level reference (1.71–5.50 V) for UART/GPIO pins - sets interface voltage domain independently of USB core. |
| USBDP / USBDM | USB Differential Data | Integrated 1.5-kΩ pull-up on USBDP and on-chip 27-Ω series termination - eliminates external USB resistors. |
| TXD / RXD | UART Transmit/Receive | CMOS-level signals; require external transceiver (e.g., MAX3232, SP3485) for RS232/RS422/RS485 physical layer. |
| RTS# / CTS# | Hardware Flow Control | Active-low handshake pair; RTS# de-asserts at 93% RX buffer fill to prevent overflow - no firmware intervention needed. |
| GPIO0–GPIO7 | Configurable I/O | Programmable as drive-0/drive-1/tristate, or functional roles (TXLED#, SLEEP#, BCD0/BCD1) - enables status indication and charger type reporting. |
| RI# | Remote Wakeup Input | Configurable as wake source; asserts remote wakeup to host when USB bus is suspended - critical for battery-powered operation. |
Key Features
| Feature | Design Value |
|---|---|
| RS485 Support | Exclusive to CY7C65213A variant - enables half-duplex multi-drop industrial networks without discrete transceiver logic changes. |
| Unique Serial Number | Flash-stored per-device ID ensures fixed COM port assignment across OS reboots and USB replug events - eliminates driver re-enumeration issues. |
| Battery Charging Detection | BCD Rev. 1.2 compliant (peripheral detect only); identifies SDP/CDP/DCP ports to optimize charge current management in portable medical devices. |
| On-Chip Oscillators | 48-MHz (USB/UART clock) + 32-kHz (suspend timing); removes crystal, load capacitors, and associated board space - reduces BOM count by ≥3 components. |
| Flash Configuration | 512-byte user-programmable flash stores VID/PID, descriptors, and GPIO settings - allows field-updatable USB identity without firmware reflash. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-to-UART bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65213-32LTXI | Lacks RS485 support; identical pinout and firmware compatibility. | Restricted to RS232/RS422-only systems; unsuitable for Modbus RTU or multi-drop networks. | Select only if RS485 is not required - lower cost but no upgrade path. |
| FTDI FT232RL | No BCD detection; requires external 6-MHz crystal; no GPIO configurability beyond TXLED/RXLED. | Requires additional components for battery charging awareness and flexible I/O signaling. | Choose when legacy FTDI driver ecosystem is mandated - but expect higher BOM cost and reduced power efficiency. |
Compared with CY7C65213-32LTXI, CY7C65213A-32LTXIT adds RS485 capability without changing layout or firmware; versus FT232RL, it delivers integrated oscillators, BCD, and flash-programmable identity - reducing component count and enabling field-upgradable USB descriptors.

FAQ
Does CY7C65213A-32LTXIT require an external crystal?
No. It integrates a fully trimmed 48-MHz oscillator for USB and UART timing, plus a 32-kHz oscillator for suspend/resume operations. This eliminates the need for external crystals, load capacitors, or clock circuitry - reducing bill-of-materials count and PCB area.
Can the COM port number be locked to avoid reassignment after USB replug?
Yes. The device supports a unique serial number feature stored in its 512-byte flash memory. When enabled, this ensures the same COM port (e.g., COM7) is assigned consistently across reboots and replugs - essential for medical and industrial software that relies on static port binding.
What UART physical layers does CY7C65213A-32LTXIT directly support?
It provides CMOS-level UART signals (TXD/RXD/RTS#/CTS#) only. RS232, RS422, and RS485 physical layers require external transceivers (e.g., MAX3232 for RS232, SP3485 for RS485). The "A" suffix explicitly enables RS485-compatible signal routing in the silicon design.
Is Linux driver support included out-of-the-box?
Yes. The device is compatible with the standard Linux kernel CDC ACM driver (since v2.6.35) and ships with the open-source libcyusbserial.so library for advanced control (baud rate, GPIO, flash programming) via user-space applications - no proprietary kernel modules required.
