Wired Connectivity

USB On-The-Go:

• PIC24FJ256GB110 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)
• Support for all four USB transfer types: control, interrupt, bulk and isochronous
• Integrated, on-chip USB transceiver, with support for off-chip transceivers via a digital interface
• Configurations for on-chip bus pull-up and pull-down resistors

Universal USB modules are shown below:

Application Examples are

ETHERNET CONTROLLER:

The Ethernet controller is a bus master module that interfaces with an off-chip Physical Layer (PHY) to implement a
complete Ethernet node in a system.

Following are some of the key features

• Supports 10/100 Mbps data transfer rates
• Supports full-duplex and half-duplex operation
• Supports RMII and MII PHY interface
• Supports MIIM PHY management interface
• Supports both manual and automatic flow control
• RAM descriptor-based DMA operation for both receive and transmit path
• Fully configurable interrupts
• Configurable receive packet filtering
  
  
  • CRC check
  • 64-byte pattern match
  • Broadcast, multicast and unicast packets
  • Magic Packet™
  • 64-bit hash table
  • Runt packet
  • Supports packet payload checksum calculation
    
    
• Supports various hardware statistics counters

Controller Area Network (CAN):

• Standards Compliance:
  
  
  • Full CAN 2.0B compliance
  • Programmable bit rate up to 1 Mbps
    
    
• Message Reception and Transmission:
  
  
  • 32 message FIFOs
  • Each FIFO can have up to 32 messages for a total of 1024 messages
  • FIFO can be a transmit message FIFO or a receive message FIFO
  • User-defined priority levels for message FIFOs used for transmission
  • 32 acceptance filters for message filtering
  • Four acceptance filter mask registers for message filtering
  • Automatic response to remote transmit request
  • DeviceNet™ addressing support
    
    
• Additional Features:
  
  
  • Loopback, Listen All Messages and Listen Only modes for self-test, system diagnostics and bus monitoring
  • Low-power operating modes
  • CAN module is a bus master on the PIC32MX system bus
  • Use of DMA is not required
  • Dedicated time-stamp timer
  • Dedicated DMA channels
  • Data-only Message Reception mode
