The Universal Serial Bus (USB) module contains
analog and digital components to provide a USB 2.0
full-speed and low-speed embedded host, full-speed
device or OTG implementation with a minimum of
external components. This module in Host mode is
intended for use as an embedded host and therefore
does not implement a UHCI or OHCI controller.
The USB module consists of the clock generator, the
USB voltage comparators, the transceiver, the Serial
Interface Engine (SIE), a dedicated USB DMA control-
ler, pull-up and pull-down resistors, and the register
interface. A block diagram of the PIC32 USB OTG
module is presented in

The clock generator provides the 48 MHz clock
required for USB full-speed and low-speed communi-
cation. The voltage comparators monitor the voltage on
the V
transceiver provides the analog translation between
the USB bus and the digital logic. The SIE is a state
machine that transfers data to and from the endpoint
buffers and generates the hardware protocol for data
transfers. The USB DMA controller transfers data
between the data buffers in RAM and the SIE. The inte-
grated pull-up and pull-down resistors eliminate the
need for external signaling components. The register
interface
communicate with the module.
The PIC32 USB module includes the following
features:
• USB Full-speed support for host and device
• Low-speed host support
• USB OTG support
• Integrated signaling resistors
• Integrated analog comparators for V
• Integrated USB transceiver
• Transaction handshaking performed by hardware
• Endpoint buffering anywhere in system RAM
• Integrated DMA to access system RAM and Flash
