Frequently Asked Questions
How does PIC16F18345-E/ML's dual ADC and DAC integration simplify closed-loop sensor control designs?
PIC16F18345-E/ML integrates both ADC inputs for sensing and DAC outputs for analog actuation on a single 8-bit chip, eliminating the need for external DAC ICs in applications like temperature-controlled heaters or analog LED dimming. Running at up to 32 MHz, the firmware can sample the ADC, compute a correction, and update the DAC output within microseconds, enabling simple proportional control loops without external analog circuitry and reducing BOM cost significantly.
What minimum supply voltage does PIC16F18345-E/ML support and how does this affect battery-powered designs?
PIC16F18345-E/ML operates from as low as 2.3V at 16 MHz, making it compatible with single-cell lithium-ion batteries discharging to near their 2.5V cutoff voltage or two-cell AA alkaline packs. This low-voltage operation extends battery runtime in IoT sensor nodes and wearable devices by allowing the firmware to continue functioning as the cell depletes, rather than shutting down early at higher voltage thresholds common with older PIC16 variants limited to 2.7V or higher.
What does the boundary scan feature of PIC16F18345-E/ML offer for manufacturing test on a 20-pin QFN board?
Boundary scan JTAG on PIC16F18345-E/ML allows automated test equipment to drive and sample all digital I/O pins through the JTAG chain, verifying PCB solder joint continuity and interconnect integrity without physical bed-of-nails probing. For the 20-pin QFN package with 0.5mm pitch pads, physical probe access is impractical, making JTAG boundary scan the preferred method for detecting open solder joints on high-density boards during incoming quality inspection and final functional test.
How does PIC16F18345-E/ML compare to PIC16F1788 for a compact sensor module design?
PIC16F18345-E/ML offers 14KB Flash and a 20-pin QFN package, making it smaller and lower cost than PIC16F1788 with its 28KB Flash and 28-pin VQFN. For sensor modules that do not require the larger memory or higher pin count, PIC16F18345-E/ML reduces PCB area and component cost while retaining the same PIC16 architecture with ADC, DAC, and 32 MHz maximum clock. Designers needing more than 14KB code space or additional I/O pins should step up to PIC16F1788.
