The picture shows CAN GM2 that has the dimension of DIP28 integrated circuit. The CAN GM2 is equipped with Atmel T89C51CC02 microcontroller.

CAN GM2 possible applications

  • Integrated system that can be used directly on the board developed by the user a macro component.
  • Connection on CAN networks with your own protocols or with standard protocols type CANopen, DeviceNet, SDS, CAN Kingdom etc.
  • Smart intelligent nodes with local functionalities as PID algorithms for controlling temperatures, motors, valves, etc.
  • Teleacquisition and telecontrol on medium and low distances.
  • Converter CAN <-> asynchronous serial line.
  • Converter CAN <-> I2C BUS line.
  • Data acquisition (either digital or analog) via CAN line.
  • Home automation: lights turning ON/OFF, heating and cooling systems control, supervision of electric devices, security and acces control systems.
  • Car automation: lights turning ON/OFF, heating and cooling systems control, supervision of electric devices, anti-teft and acces control systems, functionality checks.
  • Add CAN line in an existing system already installed.
  • Didactics: CAN GM2 offers a very low cost to learn CAN, we have many starter kits options. For this purpose it is likewise interesting the CAN GMT support Mini Module.
  • Whenever there is a short time to market: the user can see a prototype or even a ready product in one week.
  • Decentralized systems as robots, automation of production line machines, big factory automations.
  • Monitor of CAN messages in an existing system for validation or test purpose.
 

F E A T U R E

  • Micro FLASH programming or deleting can be managed by using the FLIP program available from ATMEL.
  • Single power supply required +5Vdc 26mA (the current consumption can change according with module connections).
  • Availability of power saving setting as idle mode and power down mode.
  • Atmel T89C51CC02 microcontroller (8051 code compatibile) with 14,74 Mhz crystal.
  • The CAN GM2 can be programmed both through UART and through CAN line.
  • Programmable machine speed at 12 or 6 clock cycle.
  • 16K FLASH for code, 2K FLASH for boot loader, 256 bytes RAM for data, 256 bytes ERAM for data, 2K EEPROM for data.
  • 8 A/D converter channels with 10 bits resolution, 20 µsec conversion time.
  • A/D reference voltage available on connector.
  • 14 interrupt sources with 4 priority levels.
  • 3 Timers Counters up to 16 bits
  • 2 PCA channels up to 16 bits with PWM, compare, capture, etc. functionality.
  • 18 digital I/O lines available on connector. Some of these lines have multiple functions.
  • Hardware serial line with programmable Baud Rate up to 115200 Baud, RS 232 buffered or at TTL level.
  • Transceiver MAX202E, for RS 232 serial line, with ESD protection up to ±15KV.
  • High speed CAN communication line.
  • CAN controller compatible with 2.0 A and 2.0 B standards.
  • High speed transceiver 82C250 for CAN line up to 1 Mbit (ISO-11898).
  • Reset and power supply control circuit based on MAX825.
  • Software I2C BUS line, available on connector.
  • Real Time Clock capable to manage day, month, year, week day, hours, minutes, seconds and to generate periodic interrupts.
  • 240 bytes of SRAM for configuration parameters.
  • RTC and SRAM backed with on board Lithium battery and driven by software I2C BUS line.
  • 8 configuration dip switches.
  • 1 status LED that shows the RUN or DEBUG selection or managed by software through digital I/O line.
  • Internal FLASH and EEPROM can be managed through In System Programming, or when the module is already mounted, by using the serial communication line or the CAN line.
  • Freeware software for PC, that supports the ISP programmation to dowload the generated code, inside on board FLASH.
  • Wide range of development tools as: Assembler (MCA51); C compiler (µC/51, HTC51, SYS51CW, DDS Micro C51); BASIC compiler (BASCOM 8051); PASCAL compiler (SYS51PW); etc.
  • Posibilities to implement higher level protocols, such as CANopen, DeviceNet etc.
  • Long list of demo programs and use examples supplied under source form, duly remarked, for the available development tools.

PC-based
FLexible In-system Programmer

A POWERFUL AND USER FRIENDLY SOFTWARE
TOOL TO PROGRAM ATMEL C51 FLASH MCUS

FLIP is a free PC-based software tool that supports the "In-System Programming" (ISP) of Atmel's Flash C51 microcontrollers through various communication interfaces, including RS232, USB and CAN links, both in Windows® 9x/Me/2000/XP, Windows NT® and Linux® environments FLIP can be used through a Graphical User Interface or launched from a DOS command window.
FLIP is a powerful toolset which enables the user to easily embed Atmel's ISP function libraries (DLL) within their applications without having to know the details of Atmel's ISP protocols. FLIP adds flexibility, power and user-friendliness to Atmel Flash C51 devices In-System Programming.

Available Free on Atmel's Web Site!
