The Universal Serial Bus (USB) MCU device complies with the Universal Serial Bus (USB) 2.0
specification, but it does NOT feature Hi-Speed USB (480 Mbit/s).
Each pipe/endpoint can be configured in one of several transfer types. It can be associated with
one or more banks of a dual-port RAM (DPRAM) used to store the current data payload. If sev-
eral banks are used (“ping-pong” mode), then one DPRAM bank is read or written by the CPU or
the DMA while the other is read or written by the USBB core. This feature is mandatory for iso-
chronous pipes/endpoints.

The theoretical maximal pipe/endpoint configuration (1600) exceeds the real DPRAM size (960).
The user needs to be aware of this when configuring pipes/endpoints. To fully use the 960 of
DPRAM, the user could for example use the configuration described in
Table 22-2.
Compatible with the USB 2.0 specification
Supports Full (12Mbit/s) and Low (1.5 Mbit/s) speed Device and Embedded Host

960 of Embedded Dual-Port RAM (DPRAM) for Pipes/Endpoints
Up to 2 memory banks per Pipe/Endpoint (Not for Control Pipe/Endpoint)
