PIC18F458-I/P 8-Bit Flash Microcontroller with Integrated CAN DIP-40 (PIC18F458-I/P DIP IC)
The PIC18F458-I/P is a high-performance, 8-bit Flash-based microcontroller from Microchip's advanced PIC18 family, specifically engineered for robust automotive and industrial networking. Housed in a standard 40-pin DIP package, it features an integrated CAN (Controller Area Network) 2.0B Active module, allowing it to communicate seamlessly in complex vehicle or factory environments. It utilizes a powerful RISC architecture with 75 instructions (including a single-cycle hardware multiplier) and provides 32KB of Flash program memory, 1536 bytes of RAM, and 256 bytes of high-endurance EEPROM. With its high I/O count, advanced networking capabilities, and computational throughput of 10 MIPS at 40MHz, it is a premier choice for sophisticated control applications requiring deterministic communication and high reliability.
This IC is a vital component for professional and engineering projects in India, particularly in building DIY vehicle diagnostic tools (OBD-II), industrial sensor networks, and advanced automation hubs. Its large pin count and built-in CAN controller make it a preferred alternative to the PIC18F258 for designs that require more analog inputs and digital I/O in a standard 40-pin DIP footprint.
