Frequently Asked Questions
How fast can the PIC16C73B-20/SO execute instructions and what clock source does it support?
The PIC16C73B-20/SO supports a maximum clock frequency of 20 MHz, executing most instructions in a single 200 ns instruction cycle. It accepts crystal, resonator, RC oscillator, and external clock inputs, giving designers flexibility in choosing the timing source for their embedded application.
What ADC resolution and channel count does the PIC16C73B-20/SO provide for analog signal measurement?
The PIC16C73B-20/SO integrates an 8-channel, 8-bit ADC, allowing it to sample up to 8 analog inputs simultaneously in a multiplexed fashion. This makes it well suited for sensor-based designs that need to monitor multiple analog voltages or current signals without external ADC components.
Is the PIC16C73B-20/SO suitable for applications in industrial temperature environments?
The PIC16C73B-20/SO is rated for a commercial temperature range of 0°C to 70°C. For industrial applications requiring operation down to -40°C, designers should consider the extended-temperature variants from the PIC16 family that cover the full -40°C to 85°C range.
What are the lead time and supply chain considerations for sourcing PIC16C73B-20/SO in volume?
Microchip's factory lead time for the PIC16C73B-20/SO is typically 5 weeks. Buyers procuring in volume should plan safety stock accordingly, as this is a mature part (introduced in 1990) and availability may vary. Authorized distributors typically stock the SOIC-28 package for standard-volume orders.
