PP5100 : USB Host Controller

General Description

The PP5100 single-chip controller is designed for USB 2.0 USB Full Speed and Low Speed USB Host Applications. Specifically Designed for Embedded Systems, Mobile Communications, and Consumer Products and especially optimized for USB Host MP3 Systems.

The PP5100 support one port USB Host Functions with USB Full Speed and Low Speed operations. When PP5100 meets USB Full Speed Device, it can support all type of USB Full Speed Transfers that is Interrupt /Control /Bulk/ Isochronous Transfers.

When PP5100 meets USB Low Speed Device, it can support all type of USB Low Speed Transfers that is Interrupt /Control Transfers.

Stop and Idle power-down(Suspend) modes were implemented to reduce power consumption. Using the PP5100 design approach, the following peripherals were integrated with the USB Root Hub core and USB 2.0 Full Speed and Low Speed Serial Interface Engine core and USB Host Controller core and Internal USB Bus Power Supply and Over Current Detection blocks.

• 8bit data bus and 8bit address bus for asynchronous memory bus and MCU interface
• 8bit GPIO Interface
• CS, INT, ALE pins and Active Level Options, PD pins for Direct Power Down
• 1 interrupt indicate pin
• USB Bus Power Supply over-current detect input & indicate output pin function
• Embedded 12Mhz to 48Mhz PLL for Low EMI radiation
• 48 TQFP Package
• VDD supply voltage is 4.75 ~ 5.25V, VIO supply voltage is 1.65 ~ VDD+0.3V
