Product Description

This product is under current development. Please feel free to contact us for further information.

The JCOM.AUTONET embedded board provides a development platform for designing and programming small devices for automotive networks. It is based on the NXP LPC1768 microcontroller (the optional LPc1769 provides higher clock frequency, i.e. 120 MHz compared to 100 MHz for the LPC1768).

The LPC1768 by NXP is a Cortex-M3 microcontroller for embedded applications supporting an excellent level of integration and low power consumption at frequencies of 100 MHz. The LPC1768 comes with 512 KB of flash memory, 64 kB of data memory, an Ethernet MAC, USB Device/Host/OTG, four UARTs, two CAN interfaces, three SSP/SPI, three I2C, I2S, four general-purpose timers, ultra-low power Real-Time Clock with separate battery supply, and up to 70 general-purpose I/O (GPIO) pins.

Features

  • ARM Cortex-M3 Processor LPC1768
  • Clock Frequency up to 100 MHz
  • 512 KB Flash Memory
  • 64 KB SRAM
  • 2 x CAN Bus Interface
  • 1 or 2 CAN FD Interface
  • 2 x LIN BUS Ports
  • 1 x Ethernet (external module with SPI port, only with 1-CAN-FD option)
  • 16 x GPIO with pull-up resistor for writing LEDs, reading DIP switches, etc.
  • 16 MByte flash memory for setup parameters
  • Extended Temperature Range of -40C to +85C
  • Power Supply: 5 VDC
  • Additional 12 VDC required for LIN ports
  • Hardware features selectable per jumpers to save on power consumption
  • Environmentally friendly, RoHS compliant

Automotive Network Development System With CAN, CAN FD, LIN, Ethernet

We are using the available resources (in combination with our vast code library) to create automotive networking interfaces such as Controller Area Network (CAN BUS), CAN FD (CAN with Flexible Data Rate(), Local Interconnect Network (LIN BUS), and, after all, Ethernet.

A 16 MB flash memory (SST25VF016B – SST Serial Flash Memory) provides the means of storing application-specific setup parameters.

The onboard USB (using a CP2102 Single-Chip USB-to-UART Bridge) is used for loading firmware updates.

The standard 10-pin JTAG connector allows the effective programming and debugging of embedded applications.

A set of 16 GPIO (General purpose I/O) allows the reading and writing of digital signals such as LEDs, DIP switches, etc.

Ethernet

While the LPC1768 comes with an on-chip Ethernet MAC, the JCOM.AUTONET design will not use it due to a great impact on performance and memory resources. Instead, the board provides additional SPI and UART ports to communicate with external Ethernet modules, such as:

The separation of functionality results in a multi-processor system eliminating any performance issues. Also, the breakout boards as referenced are off-the shelf products and require no protocol (TCP/IP, TCP/UDB, etc.) programming.

Note: We are weighing further options that will eventually lead to the use of the BroadR Reach technology.
