CAN MCU Tinier Than Ever

Feb. 3, 2005

Controller-area-network (CAN) microcontrollers (MCUs) continue to shrink, judging from the release of Microchip's 28-pin PIC18Fxx80 CAN MCU. It comes in a 6- by 6-mm QFN package. The family incorporates an ECAN controller to offload the 8-bit PIC processor. The processor has 16 to 32 kbytes of flash, 1.5 kbytes of RAM, and 256 bytes of EEPROM. The chip can use its internal 32-MHz clock or an external source. Peripherals include a 10-bit, 11-channel analog-to-digital converter (ADC), two analog comparators, and dual pulse-width-modulation timers that can be synchronized with the ADC. There also is an EUSART with local interconnect network (LIN) support. Extended temperature range and 80-pin versions are available. Pricing for the PIC18F4580 starts at $5.74, and the cost of the demonstration kit starts at $199.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
