USB 2.0 Interface ICs Feature Low Power, Charger Detection

The X-Chip series is provided with a feature-rich USB 2.0 interface solution made up of devices in 13 different package options. It complements the company’s existing FT-R and FT-H offerings. The series supports a broad selection of interface types, such as basic UART, full UART, FIFO and I2C, as well as FTDI’s proprietary FT1248 I/O (including provision for enhanced SPI). The X-Chip series addresses major board level concerns such as better space utilization and reduced power consumption. Devices in the series are capable of data rates of up to 3.4 Mbits/s, while maintaining low power consumption of <8mA (typical) when fully active and <125 µA (typical) while in the suspend mode. TheX-Chip has built-in functionality to detect a charging port and cause logic to switch from data transfer to charging mode.

Supported are Windows 7, Windows Vista, Windows XP, Windows XP Embedded, Windows CE, Mac OS-X, Linux 3.2 (and above), plus Android operating systems. An internal 2048-byte, multi-time programmable (MTP) memory enables storage and configuration of the necessary device descriptors.

Devices in the series are offered in compact SSOP, QFN and DFN packages. Each has an operational temperature range of -40°C to +85°C. Pricing starts at US $1.93 (for 10-49 pieces).
