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.
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
