18.0
PIC24FJ256DA210 family devices contain a full-speed
and low-speed compatible, On-The-Go (OTG) USB
Serial Interface Engine (SIE). The OTG capability
allows the device to act either as a USB peripheral
device or as a USB embedded host with limited host
capabilities. The OTG capability allows the device to
dynamically switch from device to host operation using
OTG’s Host Negotiation Protocol (HNP).
For more details on OTG operation, refer to the
“On-The-Go Supplement to the USB 2.0 Specification”,
published by the USB-IF. For more details on USB oper-
ation, refer to the “Universal Serial Bus Specification”,
v2.0.
The USB OTG module offers these features:
• USB functionality in Device and Host modes, and
• Software-selectable module speeds of full speed
• Support for all four USB transfer types: control,
• 16 bidirectional endpoints for a total of 32 unique
• DMA interface for data RAM access
• Queues up to sixteen unique endpoint transfers
• Integrated, on-chip USB transceiver with support
• Integrated V
• Configurations for on-chip bus pull-up and
A simplified block diagram of the USB OTG module is
shown in Figure 18-1.

PIC24FJ256DA210 FAMILY
The USB OTG module can function as a USB peripheral
device or as a USB host, and may dynamically switch
between Device and Host modes under software
control. In either mode, the same data paths and Buffer
Descriptors (BDs) are used for the transmission and
reception of data.
In discussing USB operation, this section will use a
controller-centric nomenclature for describing the direc-
tion of the data transfer between the microcontroller and
the USB. RX (Receive) will be used to describe transfers
that move data from the USB to the microcontroller and
TX (Transmit) will be used to describe transfers that
move data from the microcontroller to the USB.
Table 18-1 shows the relationship between data
direction in this nomenclature and the USB tokens
exchanged.
TABLE 18-1:
This chapter presents the most basic operations
needed to implement USB OTG functionality in an
application. A complete and detailed discussion of the
USB protocol and its OTG supplement are beyond the
scope of this data sheet. It is assumed that the user
already has a basic understanding of USB architecture
and the latest version of the protocol.
Not all steps for proper USB operation (such as device
enumeration) are presented here. It is recommended
that application developers use an appropriate device
driver to implement all of the necessary features.
Microchip provides a number of application-specific
resources, such as USB firmware and driver support.
Refer to www.microchip.com/usb for the latest
firmware and driver support.
