Product details
Overview
CY7C65213A-28PVXIT 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 such as blood glucose meters.
For engineers reviewing the CY7C65213A-28PVXIT datasheet, CY7C65213A-28PVXIT pinout, CY7C65213A-28PVXIT application, or CY7C65213A-28PVXIT equivalent, key selection criteria include RS485 interface support (vs. CY7C65213), BCD Rev. 1.2 peripheral detection, GPIO-configurable LED signaling, and 512-byte flash-based VID/PID/serial number persistence across COM port enumeration.
Technical Context
The device integrates a USB 2.0 Full-Speed Serial Interface Engine (SIE) with on-die 1.5-kΩ pull-up and termination resistors, eliminating external USB PHY components. Its UART subsystem implements full-duplex asynchronous communication with hardware flow control (RTS#/CTS#, DTR#/DSR#), break signal generation, and error detection for parity, framing, and overrun conditions.
Internal clocking relies solely on a factory-trimmed 48-MHz oscillator and auxiliary 32-kHz oscillator - no external crystal required. Power management includes USB suspend mode with SLEEP# assertion, bus-/self-powered operation (1.71–5.50 V), and BCD-compliant charger detection (SDP/CDP/DCP) for portable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-Speed (12 Mbps); certified per USB-IF TID 40860041 - ensures host compatibility without custom driver signing. |
| UART Max Data Rate | 3 Mbps; supports high-throughput legacy MCU telemetry and industrial sensor streaming without protocol translation. |
| TX/RX Buffer Size | 256 bytes each; enables robust burst handling during USB polling intervals and reduces host-side interrupt load. |
| Flash Memory | 512 bytes; stores persistent VID/PID, serial number, and descriptors - locks COM port assignment across reconnections. |
| Operating Voltage | 1.71 V to 5.50 V; allows direct interfacing with 1.8-V, 3.3-V, and 5-V logic domains without level shifters. |
| ESD Protection | 2.2-kV HBM; meets IEC 61000-4-2 Level 2 for front-panel USB ports in industrial enclosures. |
| Package | 28-pin SSOP (10 × 7.5 × 1.65 mm, 0.65-mm pitch); RoHS-compliant, surface-mount compatible with standard reflow profiles. |
Pinout & Package
Package: 28-pin SSOP (10 × 7.5 × 1.65 mm, 0.65-mm pitch), RoHS-compliant, lead-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCD | Digital core supply | 1.71–5.50 V input powering USB SIE, UART logic, and flash - decoupling required per layout guidelines. |
| VCCIO | I/O voltage reference | Configurable 1.71–5.50 V rail for UART/GPIO voltage level setting - independent of VCCD for mixed-voltage systems. |
| USBDP / USBDM | USB differential data pair | Integrated 1.5-kΩ pull-up on USBDP and on-die 27-Ω series termination - no external resistors needed. |
| TXD / RXD | UART transmit/receive | CMOS-level signals; require external transceiver (e.g., MAX3232, SP3485) for RS232/RS422/RS485 physical layer conversion. |
| RTS# / CTS# | Hardware flow control | Active-low handshake pair; RTS# de-asserts at 93% RX buffer fill to prevent overflow - no firmware intervention required. |
| GPIO0–GPIO7 | Configurable general-purpose I/O | Software-defined functions including TXLED#/RXLED#, SLEEP#, BCD0/1, BUSDETECT - configurable via USB utility. |
| RESET# | Active-low reset input | Asynchronous reset pin; pulls internal state machines to known default - used for system-level recovery sequences. |
Key Features
| Feature | Design Value |
|---|---|
| RS485 interface support | Enables half-duplex multi-drop communication over long cables (up to 1200 m) using external RS485 transceivers - not available in CY7C65213. |
| Unique serial number per device | Prevents COM port number drift across USB replug events - critical for field-deployed medical and industrial firmware updates. |
| Battery Charging Detection (BCD) | Identifies SDP/CDP/DCP ports per USB BC 1.2 spec - allows adaptive power draw (500 mA / 1.5 A) in portable diagnostic tools. |
| On-chip 48-MHz oscillator | Eliminates external crystal and associated load capacitors - reduces BOM count and PCB area in space-constrained designs. |
| GPIO-driven LED signaling | 8-mA drive strength on TXLED#/RXLED# pins enables direct connection to status LEDs - no current-limiting resistors required. |

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 | Requires external 6-MHz crystal; no BCD or RS485 support; 128-byte TX/RX buffers. | Lacks integrated charger detection and RS485 capability - unsuitable for battery-powered medical or multi-drop industrial use. | Select when legacy driver compatibility is mandatory and RS485/BCD are not required. |
| Cypress CY7C65211-28PVXI | Single-channel USB-UART with identical package but no RS485 support; lacks GPIO configurability for BCD/SLEEP#. | Targeted at cost-sensitive RS232-only applications; missing GPIO features needed for LED signaling and charger detection. | Choose only if RS485 and advanced GPIO control are unnecessary and BOM cost is primary constraint. |
Compared with FT232RL and CY7C65211, CY7C65213A-28PVXIT delivers differentiated value through integrated RS485 readiness, BCD Rev. 1.2 compliance, and field-programmable GPIOs - enabling single-design reuse across medical, industrial, and consumer portable platforms without hardware revision.

FAQ
Does CY7C65213A-28PVXIT require an external crystal?
No. The device integrates a factory-trimmed 48-MHz oscillator and auxiliary 32-kHz oscillator, eliminating all external timing components. This reduces bill-of-materials cost, PCB footprint, and design validation effort - confirmed in Section 5.2 "Clock System" of datasheet 001-81011 Rev. *O.
What UART physical layers does CY7C65213A-28PVXIT support?
CY7C65213A-28PVXIT supports RS232, RS422, and RS485 physical layers via external transceivers connected to its TXD/RXD/RTS#/CTS# pins. Unlike CY7C65213, it explicitly adds RS485 capability - verified in Table 1 "CY7C65213 and CY7C65213-A Features Comparison" on page 2 of the datasheet.
How is the unique serial number implemented and preserved?
A unique 128-bit serial number is factory-programmed into the 512-byte flash memory and persists across power cycles and USB replugs. It binds the device to a fixed COM port number in Windows/macOS/Linux - configured via Cypress's Windows-based USB-Serial Configuration Utility, as documented in Section 7 "Internal Flash Configuration".
Can CY7C65213A-28PVXIT operate in bus-powered mode with 3.3-V I/O?
Yes. VCCD accepts 1.71–5.50 V, and VCCIO is independently configurable within the same range. In bus-powered mode, VCCD is derived from USB VBUS (5 V), while VCCIO can be set to 3.3 V to interface directly with 3.3-V MCUs - detailed in Section 14 "USB Bus-Powered Configuration" and Table 9 "Operating Conditions".
