Description

The CY7C65620-56LTXC is a Network Interface Card (NIC) that provides a simple method to upgrade UART-based devices to USB with a minimal number of components. It includes an integrated USB 2.0 Full-Speed controller, a UART transceiver, an internal regulator, an internal oscillator, and a 512-byte flash in a 32-pin QFN and 28-pin SSOP package. The internal flash is used to store custom-specific USB descriptors and GPIO configuration.
