PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family
11.0 HI-SPEED USB WITH ON-
THE-GO (OTG)
The Universal Serial Bus (USB) module contains
analog and digital components to provide a USB 2.0
embedded host, device, or OTG implementation with a
minimum of external components.
The module supports Hi-Speed, Full-Speed, or Low-
Speed in any of the operating modes. 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 RAM controller,
packet encode/decode, UTM synchronization, end
-
point control, a dedicated USB DMA controller, pull-up
and pull-down resistors, and the register interface. A
block diagram of the PIC32 USB OTG module is
presented in
Figure 11-1.
The USB module includes the following features:
• USB Hi-Speed, Full-Speed, and Low-Speed
support for host and device
• USB OTG support with one or more Hi-Speed,
Full-Speed, or Low-Speed device
• Integrated signaling resistors
• Integrated analog comparators for VBUS
monitoring
• Integrated USB transceiver
• Transaction handshaking performed by hardware
• Integrated 8-channel DMA to access system RAM
and Flash
• Seven transmit endpoints and seven receive
endpoints, in addition to Endpoint 0
• Session Request Protocol (SRP) and Host
Negotiation Protocol (HNP) support
• Suspend and resume signaling support
• Dynamic FIFO sizing
• Integrated RAM for the FIFOs, eliminating the
need for system RAM for the FIFOs
• Link power management support

Note 1: The implementation and use of the USB
specifications, as well as other third party
specifications or technologies, may
require licensing; including, but not

(also referred to as USB-IF). The user is
fully responsible for investigating and
satisfying any applicable licensing
obligations.
2: If the USB module is used, the Primary
Oscillator (P
OSC) is limited to either
12
MHz or 24 MHz.
