The new CY7C6521x family of of USB-Serial bridge controllers from Cypress Semiconductor provides dual-configurable serial channels for UART/SPI/I2C communication along with CapSense capacitive touch-sensing technology, enabling flexible design of human interface solutions. Proprietary drivers support multiple operating systems. The family integrates efficient battery-charge detection compliant to Version 1.2 of the USB-Implementers Forum (USB-IF) Battery Charging specification. Additionally, and boasts low power consumption of 5 uA (standby current).
The new family includes three devices, all of which are certified by the USB-IF. The CY7C65211 and CY7C65215 offer single- and dual-configurable serial channels, respectively, with each capable of UART, I2C, and SPI communication. The CY7C65213 provides a low power USB-to-UART bridge controller. The new controllers target a wide range of applications, including medical equipment, industrial equipment, point-of-sales terminals, USB-to-UART and RS232 cables, gaming systems, and test and measurement equipment.
Cypress provides a software configuration utility for Windows that enables customers to select from multiple serial interfaces and features to create customized designs. This utility also assists customers in modifying various parameters, such as vendor and product IDs, string descriptors, and GPIO configurations, via the USB interface. USB-Serial integrates programmable memory used to store these configuration details. The utility, drivers, and application programming interfaces (APIs) provided by Cypress makes it very easy for customers to develop complete solutions with shorter design cycles, resulting in quick time-to-market.
