Chandler, Ariz. Microchip Technology Inc.'s new four-member PIC18F4685 family of low-power 8-bit Controller Area Network (CAN) microcontrollers boasts 80 or 96 Kbytes of flash and integrated EEPROM memory to accommodate the growing complexity of CAN applications.
This is the largest amount of program memory available on any PIC18 microcontroller with an onboard ECAN module for CAN connectivity, according to Microchip. Additionally, automotive and industrial designers can benefit from the small 28- and 44-pin package sizes of this family for space-constrained applications.
Industry-standard CAN protocols are growing in size, often leaving little code space for the application program. The PIC18F4685 offers enough code space for both the CAN protocol and advanced applications. And, each microcontroller in this family features Microchip's ECAN module, an easy-to-use scalable CAN 2.0B solution with the ability to switch between standard CAN operations and FIFO mode.
"Low-power CAN applications are becoming increasingly complex, requiring much larger code space for advanced features," said Mitch Obolsky vice president of Microchip's Advanced Microcontroller Architecture Division. "The PIC18F4685 family accommodates these requirements by offering customers a migration path from Microchip's low-power 32 and 64 Kbyte CAN families to 80 and 96 Kbyte Flash memory."
A broad range of applications can take advantage of the reliable, highly noise immune CAN protocol via the PIC18F4685 family, including automotive (suspension, steering, airbags, climate control, collision avoidance/backup warning systems, infotainment, wireless receiver modules) and industrial (remote sensors and actuators).
All four Flash microcontrollers are supported by Microchip's development tools, including the MPLAB Integrated Development Environment (IDE) and MPLAB ICD2 In-Circuit Debugger. The PICDEM CAN-LIN 2 Demonstration Board (part# DM163011) shows the functionality of the integrated CAN module features on these devices, and is available now for $199.
The PIC18F4685/4682/2685/2682 microcontrollers are available now for general sampling at
