MPN: CY7C65213A-28PVXI ✓ AktifCY7C65213A-28PVXI Ringkasan
A USB-UART bridge controller is an interface IC that translates between the Universal Serial Bus protocol and a serial UART peripheral. It sits within a broader USB interface-controller and power-management hierarchy, allowing equipment with a legacy UART connector to adopt USB without requiring a complex host-side protocol implementation. The CY7C65213 family is particularly relevant to industrial control, data acquisition, configuration ports, and service equipment.
The main technical benefits include USB 2.0 full-speed operation, a 3 Mbps UART data rate, and RS485 capability. The integrated 512-byte flash supports device-specific configuration and control, while the internal regulator and oscillator reduce the number of external support components. A 28-pin SSOP package also allows reuse of compact, low-cost PCB layouts designed around the CY7C65213A family.
The device integrates several subsystems normally implemented separately in a USB-to-serial conversion. Its USB controller handles full-speed enumeration and data transfer, its UART transceiver communicates with the downstream equipment, and the internal flash stores configuration data. The RS485-oriented variant adds support for applications where longer, noise-prone industrial links require stronger interface characteristics than a conventional UART point-to-point connection.
Typical uses include USB-to-RS485 adapters, industrial serial gateways, programmable controller service interfaces, laboratory data-acquisition equipment, and legacy UART products that need a USB update path. Designers can use the bridge to reduce host-side software complexity while retaining access to established UART peripherals. Its internal regulator and oscillator are especially useful where minimizing external components and board area matters.
Layout and firmware remain important engineering considerations. USB differential traces require a controlled impedance PCB stack-up, short matched routing, and careful placement of the USB connector and decoupling. Firmware must configure the internal UART and RS485 functions correctly for the intended baud rate, electrical environment, and data direction. The pin-description table and recommended application circuit in the manufacturer datasheet should govern connector and external-component assignments.
This page combines the manufacturer’s core USB, UART, RS485, flash, package, and ordering information with a focused engineering analysis. It also documents data-availability limits, distinguishes the non-RS485 family member from the RS485-capable target, and provides application guidance that helps teams evaluate the bridge before committing a PCB layout or production design.

Aplikasi Biasa
CY7C65213A-28PVXI patut untuk 6 aplikasis: USB-to-RS485 Industrial Adapter, Legacy UART Equipment USB Upgrade, Industrial Data-Acquisition Gateway, Programmable Controller Service Port, Laboratory Instrument Communication, USB Configuration and Diagnostic Port.
USB-to-RS485 Industrial Adapter
The CY7C65213A-28PVXI fits a compact USB-to-RS485 adapter because it combines Full-Speed USB 2.0, a UART interface capable of 3 Mbps, and RS485 support in one 28-pin SSOP device. A host computer can then access an RS485-connected instrument through a USB port without implementing the USB protocol in the downstream controller. The bridge handles USB-to-serial translation while the board provides the appropriate external RS485 transceiver, bus protection, termination, connector, and isolation as required by the installation.

Legacy UART Equipment USB Upgrade
The CY7C65213A-28PVXI provides a practical path for adding USB to equipment built around a legacy UART peripheral. Its integrated USB controller, UART transceiver, regulator, oscillator, and 512-byte flash reduce the number of discrete components required for the interface. At the system level, the bridge allows the original UART-based operating logic to remain in place while a PC or service laptop communicates over USB. Firmware must handle enumeration, baud-rate configuration, data framing, and any RS485 direction-control behavior required by the product.

Industrial Data-Acquisition Gateway
The CY7C65213A-28PVXI can serve as the USB-facing serial engine in an industrial data-acquisition gateway. USB 2.0 Full-Speed provides a standard host connection, while the 3 Mbps UART rate supports acquisition peripherals that require more throughput than a low-speed serial link. Its internal regulator, oscillator, and 512-byte flash simplify the bridge section of the board. Designers should place the USB connector and differential traces carefully, isolate noisy motor or relay circuits, and provide appropriate protection at externally accessible connectors.
Disebarkan
Programmable Controller Service Port
The CY7C65213A-28PVXI is suitable for adding a service and configuration port to a programmable controller that already exposes a UART interface. USB Full-Speed connectivity simplifies field updates, diagnostics, and production programming, while the integrated 512-byte flash can retain configuration information associated with the bridge. The 28-pin SSOP format supports compact controller boards. Firmware should expose the same configuration functions available through the original UART path and should include timeout and recovery behavior for disconnected or misconfigured hosts.
Disebarkan
Laboratory Instrument Communication
The CY7C65213A-28PVXI can connect a laboratory instrument with a legacy serial interface to a modern USB-equipped computer. Full-Speed USB and a 3 Mbps UART rate support command traffic, measurement transfer, and firmware updates when paired with suitable host software. The integrated regulator and oscillator simplify analog or mixed-signal instrument boards that need a compact isolation boundary between USB and the instrument’s UART circuitry. Separate analog and digital grounding, ESD protection, and enclosure treatment remain essential for reliable measurement performance.
Disebarkan
USB Configuration and Diagnostic Port
The CY7C65213A-28PVXI is well suited to configuration and diagnostic ports because it adds a standard USB connection to a UART-based product without requiring a separate USB controller. Host software can issue configuration commands, retrieve status information, and perform diagnostics through the integrated bridge. The A variant’s RS485 capability is useful when the diagnostic port connects to distributed industrial nodes rather than a single local peripheral. Designers should define command framing and device enumeration carefully so multiple similarly named instruments can be identified without ambiguity.

Catatan Desain
Route the USB differential pair as a short, continuous, impedance-controlled pair using the PCB stack-up selected for the target connector and cable. Keep the USB connector, controller, and local decoupling in the same region, avoid stubs and test-point structures on the pair, and place the differential connection away from switching nodes and high-current return paths. Compliance should be checked against the USB Full-Speed requirements and the complete board stack-up.
Use the manufacturer pin-description table and reference circuit when placing decoupling, configuration components, and the external RS485 interface. Place input and output capacitors directly at their designated pins, connect the ground and supply return paths without long loops, and keep sensitive signal routing away from the USB connector and transceiver area. Confirm every no-connect position before fabrication and do not assign undocumented functions to unused pins.
Do not assume that the closely related CY7C65213-28PVXI is interchangeable with the A variant in an RS485 design. The target provides RS485 capability, while the related family member does not provide the same feature. Also verify whether the design expects the bridge to source an external transceiver supply or interface only with the UART signals; power architecture, transceiver direction control, and firmware configuration must be reviewed together.
