The PL2551 is a single chip Hi-Speed USB 2.0 General-Purpose Microcontroller (MCU). It provides customer a cost-effective and time-to-market USB device controller solution.
PL2551 Hi-Speed USB General Purpose Device Controller
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.
