Frequently Asked Questions
At what minimum supply voltage can the PIC16F18325-I/ST operate, and does that limit its maximum clock speed?
The PIC16F18325-I/ST operates at a minimum of 2.3V supply, but at that voltage it is limited to 16 MHz maximum clock frequency. For the full 32 MHz operation, a higher supply voltage is required. This graduated voltage-frequency relationship lets designers optimize power consumption by lowering voltage and frequency together in battery-powered applications.
Which embedded designs benefit most from the PIC16F18325-I/ST's integrated DAC and ADC combination?
Designs that need to both read and generate analog signals — such as thermostat controllers, analog sensor calibration circuits, and audio tone generators — benefit most from having on-chip DAC and ADC channels. The PIC16F18325-I/ST eliminates the need for external converters, reducing BOM count and PCB area. Applications like 4–20 mA current loop transmitters or resistive sensor bridges are common use cases.
How many pins does the PIC16F18325-I/ST have, and what communication interfaces are available on those pins?
The PIC16F18325-I/ST is packaged in TSSOP-14 with 14 pins total. Despite the compact pin count, it exposes UART, SPI, and I2C serial interfaces through its peripheral pin select (PPS) feature, allowing flexible assignment of communication functions to available I/O pins. This flexibility is valuable in designs where board layout constrains signal routing.
When would a designer choose the PIC16F18325-I/ST over a larger PIC16 variant with more pins?
When the application requires fewer than 12 GPIO lines and benefits from the smallest possible PCB footprint, the 14-pin TSSOP PIC16F18325-I/ST is preferable to larger 28-pin or 40-pin variants. Cost savings are also significant in high-volume production; at 32 MHz core speed and with integrated ADC plus DAC, the device matches the capability of more expensive mid-range 8-bit MCUs for simple control tasks.
