Frequently Asked Questions
What is the maximum clock frequency of PIC18F258-I/SO and how does it affect throughput?
PIC18F258-I/SO operates at up to 40 MHz, delivering up to 10 MIPS sustained throughput. Each instruction executes in a single cycle, so at 40 MHz the part handles 10 million single-cycle instructions per second, enabling responsive real-time control tasks in embedded applications.
Which communication interfaces does PIC18F258-I/SO support for connecting to CAN networks?
PIC18F258-I/SO includes an integrated CAN 2.0B active controller, plus SPI and I2C serial interfaces. The CAN module supports standard and extended frames at up to 1 Mbps, making it suitable for automotive and industrial networks requiring multi-node communication over a 2-wire differential bus.
How much non-volatile memory does PIC18F258-I/SO provide for firmware and data storage?
PIC18F258-I/SO provides 32 KB of self-write flash program memory, 1536 bytes of SRAM, and 256 bytes of data EEPROM. The EEPROM supports at least 1,000,000 erase/write cycles, making it reliable for storing configuration parameters or calibration data that must survive power cycles.
When is PIC18F258-I/SO a better fit than a 16-bit MCU for a compact motor-drive design?
For cost-sensitive 8-bit control loops running at 40 MHz in a 28-pin SOIC footprint, PIC18F258-I/SO avoids the higher unit cost and wider PCB footprint of typical 16-bit devices. Its 2V minimum supply and CAN 2.0B interface let designers share a single MCU for both motor-drive logic and network communication in a board area under 200 mm².
