Frequently Asked Questions
How many A/D input channels does PIC16C73B-20/SP provide and at what resolution?
The PIC16C73B-20/SP integrates an 8-channel A/D converter with 8-bit resolution, allowing direct analog measurement from up to 8 sensor inputs without external ADC ICs. This reduces BOM cost and PCB area in temperature sensing, light metering, or resistive sensor readout applications running at clock speeds up to 20 MHz.
For which legacy or through-hole prototyping scenarios is the 28-pin SPDIP package of PIC16C73B-20/SP the right choice?
The 28-pin SPDIP package is ideal for breadboard prototyping, hand-soldered prototype runs, and replacement of existing through-hole MCU designs where changing to SMT would require board re-spin. At 20 MHz and 5 V operation, it slots directly into existing DIP-28 sockets on legacy industrial control cards and educational evaluation boards.
When should an engineer prefer PIC16C73B-20/SP over a flash-based PIC16F part?
PIC16C73B-20/SP uses OTP (one-time programmable) memory, which suits high-volume production where code is locked at manufacture and cannot be altered in the field, reducing security and IP concerns. For designs locked at 20 MHz and 5 V with no requirement for field firmware updates, the OTP variant can be lower-cost per unit than a flash equivalent, though prototyping requires a separate flash-based evaluation device.
