USB Device Controller Features
- Fully compliant with USB 2.0 Full-speed specification.
- Supports 32 physical (16 logical) endpoints.
- Supports control, bulk, interrupt and isochronous endpoints.
- Scalable realization of endpoints at run time.
- Endpoint maximum packet size selection (up to USB maximum specification) by software at run time.
- RAM message buffer size based on endpoint realization and maximum packet size.
- Supports SoftConnect and GoodLink LED indicator. These two functions are sharing one pin.
- Supports bus-powered capability with low suspend current.
- Supports DMA transfer on all non-control endpoints (LPC2146/48 only).
- One duplex DMA channel serves all endpoints (LPC2146/48 only).
- Allows dynamic switching between CPU controlled and DMA modes (only in LPC2146/48).
- Double buffer implementation for bulk and isochronous endpoints.
