89C2051 datasheet

General Information

The 89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read-only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.

GL3522 Hub Controller

The texts in the PDF file :

GL3522 is a 4-port, low-power, and configurable hub controller. It is compliant with the USB 3.1 Gen 1 specification. GL3522 integrates Genesys Logic self-developed USB 3.1 Gen 1 Super Speed transmitter/receiver physical layer (PHY) and USB 2.0 High-Speed PHY. It supports Super Speed, Hi-Speed, and Full-Speed USB connections and is fully backward compatible to all USB 2.0 and USB 1.1 hosts. GL3522 also implements multiple TT* (Note1) architecture providing dedicated TT* to each downstream (DS) port, which guarantees Full-Speed(FS) data passing bandwidth when multiple FS devices perform heavy loading operations. Furthermore, GL3522 has built-in 5V to 3.3V and 5V to 1.2V regulators, which saves customers’ BOM cost, and eases for PCB design.  [ … ]
