Why is it necessary to upgrade the UART interface on a device? There is an absolute need to upgrade to USB connectivity because USB is ubiquitous. The latest PCs in the market have only USB ports and UART ports are disappearing. The problem is simple but the solution is not. In most cases it requires a change of design including hardware and software. However, there are many devices with UART interfaces that require connectivity to PCs - industrial devices, medical devices, meters, set-top boxes, servers, and point of sale systems such as barcode scanners and printers. Cypress’ USB to UART controller is a simple, easy-to-design solution that requires no firmware or software development. The Cypress bridge controller CY7C65213 enables seamless PC connectivity for UART devices.
