The picture shows CANPIC that has the dimension of DIP28 integrated circuit. The CANPIC is equipped with Microchip PIC18LF4680 microcontroller.

CANPIC 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: CANPIC 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.


  • Standard container with 28 pin male socket, dual in line, 100 mils pitch, 600 mils width.
  • Very small dimension: 25,5 x 42,7 x 14,3 mm.
  • Weight: 12 g.
  • 4 layers printed circuit to obtain best noisy resistance and best EMI performance.
  • No external programmer is needed as CANPIC is a grifo® ISP (In System Programming) Mini Module. FLASH of Micro is Programmable and Erasable by using ISP line only.
  • Single power supply voltage required in the wide range from 3,0 to 5 Vdc, 25mA max.
  • Availability of power saving setting as idle mode and power down mode.
  • Microchip PIC18LF4680 microcontroller (with 10,00 MHz crystal.
  • 64K FLASH, 4K RAM for data, 1K EEPROM for data.
  • Real Time Clock capable to manage day, month, year, week day, hours, minutes, seconds and to generate periodic interrupts.
  • Real Time Clock, Philips PCF 8583, with 240 bytes of internal SRAM.
  • RTC and SRAM backed with on board Lithium battery and driven by software I2C BUS line.
  • 10 A/D converter channels with 10 bits resolution.
  • Internal reference voltage available.
  • 3 Timers Counters
  • 1 CCP channel with PWM, compare, capture, etc. functionality.
  • Parallel Slave Port (PSP).
  • 23 digital I/O lines available on connector. Some of these lines have multiple functions.
  • I2C BUS controller, completely software configurable.
  • SPI interface programmable for syncronous, high speed communications.
  • Hardware serial line with programmable Baud Rate up to 115200 Baud, RS 232 buffered or at TTL level.
  • Transceiver MAX3222E, 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).
  • 8 configuration dip switches.
  • 2 status LED that shows the RUN or DEBUG selection or managed by software through digital I/O lines.
  • 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; Debugger (MicriCode Studio); C compiler (PICC); BASIC compiler (PicBasic, PicBasic Pro, mikroBASIC);PASCAL compiler (mikroPASCAL); etc.
  • Long list of demo programs and use examples supplied under source form, duly remarked, for the available development tools..

MicroCode Studio

MicroCode Studio

MicroCode Studio is a powerful, visual Integrated Development Environment (IDE) with In Circuit Debugging (ICD) capability designed specifically for PICBasic Pro compiler. The main editor provides full syntax highlighting of your code with context sensitive keyword help and syntax hints. The code explorer allows you to automatically jump to include files, defines, constants, variables, aliases and modifiers, symbols and labels, that are contained within your source code. Full cut, copy, paste and undo is provided, together with search and replace features.

PicBasic Compiler PLUS

The low-cost PicBasic Compiler PLUS (PBC) makes it easy to write programs for the fast Microchip PICmicro MCU. PBC converts these programs into hex or binary files that can be programmed directly into a PICmicro microcontroller. The easy-to-use BASIC language makes PICmicro MCU programming available to everyone with its English-like instruction set. No more scary assembly language!

PicBasic Pro Compiler

The PicBasic Pro Compiler is the easiest way for you to program the fast and powerful Microchip Technology PICmicro microcontrollers. PicBasic Pro converts your BASIC programs into files that can be programmed directly into a PICmicro MCU.

FlowCode V3

Flowcode 3 is one of the world's most advanced graphical programming languages for microcontrollers. The great advantage of Flowcode is that it allows those with little experience to create complex electronic and robotic systems. Flowcode is a powerful language that uses macros to facilitate the control of complex devices like 7-segment displays, motor controllers, and LCD displays.
