Description
With diversity of IO ports and peripherals, it can easily interface with various external devices and applications such as motion sensor, modem, CMOS sensor, medical/healthcare, industrial, fingerprint, security, and others. Flexible endpoint configuration including its buffer partition allows users to easily establish control of isochronous in/out (ISO),
bulk-in/out or interrupt in/out (INT) pipes to communicate with USB host. In addition, it is possible to configure the chip as a composite or a compound device. The PL2551 is designed to be flexible, high performance and easy-to-use so that customers can easily implement into their products.
