USB-Serial (Dual Channel) Development Kit




The CYUSBS236 DVK is designed as an easy-to-use kit, showcasing the unique features of Cypress's CY7C65215 USB-Serial bridge controller. This device includes CapSense® , Cypress's leading capacitive touch-sensing technology, and the Battery Charger Detect ion (BCD) feature, which is compliant with the USB Implementers Forum (USB-IF) Battery Charging Specification. This kit includes four EEPROMs to demonstrate I2C and SPI, two RS-232 line-drivers for UART, two CapSense touch buttons, and a Lithium ion (Li ) battery charger circuit. The CY7C65215 device supports bus-powered and self-powered modes and enables efficient system power management with suspend and remote wake-up signals.
CY7C65215 is the first full-speed USB-Serial bridge controller that offers a dual-channel configurable serial interface (UART/I2C/SPI). The controller also features Battery Charging Detection (BCD) and capacitive touch sensing at low suspend-state currents of 5 uA. The controller is offered in a 5x5-mm, features up to 19 pins for GPIO and is available in 32-pin QFN package to meet the dimensional requirements of portable devices. The controller is USB-IF certified with TID# 40860041.
Key Applications: Portable medical devices (like blood-glucose meters), Point-of-sales terminals, Serial Cables (including USB-to-UART and RS232 cables) and many other applications requiring USB connectivity.
