Frequently Asked Questions
What maximum clock speed does PIC18F46K42-I/PT support and how does it benefit control loop performance?
The PIC18F46K42-I/PT operates at a maximum clock frequency of 64 MHz, enabling it to execute 16 million single-cycle instructions per second. This throughput is sufficient for real-time PID control loops at 1 kHz update rates in motor drives, thermostat controllers, and sensor data-logging applications, while still leaving processing headroom for communication stack tasks such as UART, SPI, or I2C transactions.
Does PIC18F46K42-I/PT include both ADC and DAC peripherals on-chip?
Yes. The PIC18F46K42-I/PT integrates both ADC and DAC channels on the same die, allowing it to digitize analogue sensor inputs and simultaneously generate analogue reference or control output voltages without external converter ICs. This dual analogue capability in a 44-pin TQFP package reduces BOM cost and PCB area in mixed-signal applications such as temperature controllers, audio pre-amplifiers, and industrial process monitors.
For a long-production-run industrial product, how does PIC18F46K42-I/PT's YTEOL of 18 years affect procurement risk?
A YTEOL (Years To End Of Life) of 18 years means the PIC18F46K42-I/PT is expected to remain in active production until approximately 2035, which substantially reduces long-term supply risk for industrial products with 10-15 year production runs. Designers can confidently design-in this 8-bit MCU knowing Microchip's lifecycle commitment covers the full product generation, avoiding costly re-qualification or re-spins that would be required if a shorter-lived MCU reached end-of-life mid-production.
