USB Connectivity for UART Devices

Single-Chip USB-to-UART Bridge Controller:

Easy-to-Design Solution Reduces Time-to-Market

001-78134 Rev *GPresentation: To provide an engineering overview to customers for a Cypress solution.Title slide: To define what the presentation will cover. The subtitle is a one-sentence statement of the key opportunity.


Upgrade Your UART Device to USB

The market demands USB connectivity for legacy UART DevicesNew PCs have USB ports, but no UART ports

The problem is simple, but the solution is not

Many UART devices still need to connect to PCs, including:Industrial devices, medical devices, meters, set-top boxes, and servers and POS devices, such as barcode readers and printers

Cypress USB-to-UART Bridge Controller is a simple, easy-to-design solutionIt solves a widespread problem without requiring any software driver development

Cypress USB-to-UART Bridge Controller enables seamless PC connectivity for legacy UART devices

Market Vision: To define the market opportunity. Presents compelling data and end product photos relevant to the local market.3

1. Legacy devices with a UART port cannot connect to new PCsThey require bridging hardware and a software driver to make the connection

2. Integrating USB connectivity into these devices is expensive, time-consuming and error-prone

3. You need a reliable supplier of USB-to-UART Bridge ControllersExisting suppliers have problems with unstable software drivers and VID/PID configurability

Cypress USB-to-UART Bridge Controller (CY7C65213) solves these problemsProvides seamless PC connectivity for UART devices

Retrofits existing systems with an easy-to-use Active Cable solution that requires no redesign of any kind

Provides a stable CDC software driver and a VID/PID Configuration Utility

Cypress USB-to-UART Bridge Controller is a plug-and-play solution from the USB market leader

Design Problems Engineers Face

Traditional Approach and Challenges: To present the traditional approach and the challenges engineers will face when using it to realize the Market Vision. Ends with a one-sentence segue clearly stating the benefit of the Cypress solution.
