PIC18F258-I/SP 8-Bit Flash Microcontroller with CAN and NanoWatt Technology DIP-28 (PIC18F258-I/SP DIP IC)
The PIC18F258-I/SP is a high-performance, 8-bit Flash-based microcontroller from Microchip's advanced PIC18 family, specifically designed for applications requiring robust networking via an integrated CAN (Controller Area Network) module. Housed in a 28-pin Skinny DIP package, it features a powerful RISC architecture with 75 instructions and 32KB of Flash program memory. This IC is a specialized variant of the PIC18F252, adding a full CAN 2.0B Active controller, making it ideal for automotive and industrial environments. With 1536 bytes of RAM, 256 bytes of EEPROM, and a 5-channel 10-bit ADC, it provides a sophisticated platform for complex, networked control tasks that require deterministic communication.
This IC is primarily used in automotive control units, industrial automation nodes, and professional diagnostic tools. It is an essential component for Arduino and robotics projects in India for building DIY CAN bus interfaces, vehicle-to-everything (V2X) communication prototypes, and multi-node industrial monitoring systems that require high memory capacity and reliable networking in a 28-pin DIP footprint.
