Product details
Overview
CY7C65213A-32LTXI from Cypress Semiconductor is a USB 2.0 Full-Speed (12 Mbps) USB-to-UART bridge controller supporting RS232/RS422/RS485 physical layer interfacing, 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-32LTXI datasheet, CY7C65213A-32LTXI pinout, CY7C65213A-32LTXI application, or CY7C65213A-32LTXI equivalent, key selection criteria include RS485 support (vs. CY7C65213), BCD 1.2 peripheral detection, GPIO-configurable LED signaling, VCCIO voltage range (1.71–5.50 V), and industrial temperature operation (–40 °C to +85 °C).
Technical Context
The device integrates a USB 2.0 Serial Interface Engine (SIE), single-channel UART with hardware flow control (RTS#/CTS#, DTR#/DSR#), and configurable GPIOs - all clocked by an internal 48-MHz oscillator eliminating external crystal requirements. It implements CDC, PHDC, and vendor-class USB device enumeration.
USB suspend/resume is managed via SLEEP# output and RI# remote wakeup capability; battery charging detection (BCD Rev. 1.2) supports SDP/CDP/DCP port identification using dedicated BCD0/BCD1 pins, while 512-byte flash stores VID/PID, serial number, and descriptors programmable in-system via Windows configuration utility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-Speed (12 Mbps); compliant with USB-IF TID 40860041 and USB 2.0/3.0 host controllers. |
| UART Data Rate | Up to 3 Mbps; supports non-standard baud rates via configuration utility - enables legacy MCU interface at high throughput. |
| Buffer Size | 256 bytes TX + 256 bytes RX; prevents overrun during burst transfers in embedded telemetry applications. |
| Operating Voltage | 1.71 V to 5.50 V VCCIO; allows direct interfacing with 1.8 V, 3.3 V, or 5 V logic without level shifters. |
| Temperature Range | –40 °C to +85 °C (industrial grade); validated for use in factory-floor T&M and outdoor POS enclosures. |
| ESD Protection | 2.2-kV HBM; meets IEC 61000-4-2 Level 2 for robustness in handheld medical and portable instrumentation. |
| Flash Memory | 512 bytes; stores immutable serial number, custom VID/PID, and manufacturer descriptors - fixes COM port assignment across reboots. |
Pinout & Package
Package: 32-pin QFN (5 × 5 × 1 mm, 0.5-mm pitch), RoHS-compliant, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCIO | I/O supply voltage input | Configures logic level for UART/GPIO pins (1.71–5.50 V); decoupling required per layout guidelines. |
| USBDP / USBDM | USB differential data pair | Integrated 1.5-kΩ pull-up on USBDP; internal 27-Ω series termination eliminates external resistors. |
| TXD / RXD | UART transmit/receive data | CMOS-level signals; require external transceiver (e.g., MAX3232, SP3485) for RS232/RS485 physical layer. |
| RTS# / CTS# | Hardware flow control pair | Active-low handshake; RTS# de-asserts at 93% RX buffer fill to prevent overflow in continuous streaming. |
| GPIO0–GPIO7 | Configurable general-purpose I/O | Programmable as drive-0/drive-1/tristate/SLEEP#/TXLED#/RXLED#/BCD0/BCD1/BUSDETECT - no external pull-ups needed. |
| RI# | Ring indicator / remote wakeup | Configurable as wakeup source; asserts remote wakeup only if enabled in USB descriptor and host permits. |
Key Features
| Feature | Design Value |
|---|---|
| RS485 Support | Exclusive to CY7C65213A variant - enables half-duplex multi-drop industrial bus connectivity without external protocol translation. |
| Unique Serial Number | Per-device immutable ID stored in flash - ensures consistent COM port assignment across OS reinstalls and USB hot-plug cycles. |
| Battery Charging Detection | BCD Rev. 1.2 peripheral-mode detection (SDP/CDP/DCP) - enables intelligent power management in portable medical and handheld devices. |
| GPIO-Driven LED Signaling | TXLED#/RXLED# pins drive LEDs at 8-mA strength - provides real-time visual status without external drivers or current-limiting resistors. |
| Bus-/Self-Powered Flexibility | Supports both configurations with internal regulator; VBUS sensing via BUSDETECT pin enables automatic mode switching. |

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 |
|---|---|---|---|
| Ftdi FT232RL | No integrated BCD; requires external 6-MHz crystal; 256-byte buffers; supports RS232 only (no RS485). | Lacks native RS485 and battery charge detection - unsuitable for medical or industrial multi-drop systems. | Select when cost sensitivity outweighs RS485 need and external crystal is acceptable. |
| Cypress CY7C65213-32LTXI | Same package and pinout but lacks RS485 support; identical UART, GPIO, and flash features. | Cannot interface directly to RS485 transceivers - limits use to RS232/RS422-only legacy upgrades. | Select only if RS485 is unnecessary and BOM must avoid over-specification. |
Compared with FT232RL and CY7C65213-32LTXI, CY7C65213A-32LTXI uniquely delivers RS485 compatibility, BCD 1.2 detection, and crystal-free operation - making it optimal for industrial and medical designs requiring robust physical-layer flexibility and power-aware USB connectivity.

FAQ
Does CY7C65213A-32LTXI require an external crystal?
No. The device integrates a precision 48-MHz oscillator and does not require an external crystal or resonator - reducing BOM count, PCB area, and startup time. This oscillator meets USB Full-Speed timing accuracy requirements without calibration.
Can CY7C65213A-32LTXI be used for RS485 communication?
Yes - CY7C65213A supports RS485 physical layer interfacing via its UART pins (TXD/RXD) connected to an external RS485 transceiver (e.g., SP3485). This capability distinguishes it from CY7C65213, which supports only RS232/RS422.
How is the unique serial number implemented?
A factory-programmed, immutable serial number is stored in the 512-byte internal flash. When configured via Cypress's Windows utility, it binds the device to a fixed COM port number across OS sessions and USB replugs - eliminating port enumeration instability in production systems.
What USB device classes does CY7C65213A-32LTXI support?
It supports USB Communication Device Class (CDC) for standard VCP operation, Personal Healthcare Device Class (PHDC) for medical interoperability, and vendor-specific class for custom host applications - all selectable via configuration utility without firmware changes.
