Description

The CAN/CAN gateway CG-ARM7/D/E is designed for applications where there is a demand for higher flexibility. Both the supply voltage range and the operating temperature range are extended in a way that the use in automotive applications is possible. With the development kit and the ability to use its USB interface to configure the device, to download new firmware and to supply power, CG-ARM7/D/E performs as a versatile development platform for CAN/CAN gateway applications. Firmware, which has been developed on this device can also be run on CG-ARM7 and CG-ARM7/GTI.Among the available functions of the standard firmware are data rate adaption, message filtering as well as identifier conversion between the coupled busses. The restriction of the maximum data rate depending on cable length for single CAN segments can be abolished for the over-all system by use of CG-ARM7/D/E.CG-ARM7/D/E obtains its potential through the use of a 32 bit microcontroller with 48 MHz clock. High speed processing and low latencies allow the use with high data rates and busloads.CG-ARM7/D/E is available in versions HS/LS and LS/LS allowing the conversion of high speed to low speed and low speed to low speed CAN.

Technical Data

Layout and Connection

The connection of the CAN bus is done by a D-Sub9 male and female plug. These are also used as default power supply connection. An USB interface is provided for configuration, firmware download and optional power supply purposes.

Limiting Values

Parameter	Minimal	Maximal	Unit
Storage temperature	-40	+80	°C
Operating temperature	-40	+70	°C
Supply voltage	-40	+35	V
Voltage on bus connections	-30	+30	V
