Frequently Asked Questions
How much Flash and RAM does the PIC32MX170F256D-50I/PT have, and what clock speed does it support?
The PIC32MX170F256D-50I/PT includes 256 KB of program Flash memory, an additional 3 KB of boot Flash, and 64 KB of SRAM, operating at a maximum clock frequency of 50 MHz. This memory and speed profile is well suited for real-time embedded control applications requiring moderate code size and fast data processing.
Which ADC resolution does the PIC32MX170F256D-50I/PT provide, and how does that affect sensor interface design?
The PIC32MX170F256D-50I/PT features a built-in 10-bit ADC, which provides 1024 discrete voltage levels across the reference range. For a 3.3 V supply this yields approximately 3.2 mV resolution per LSB, adequate for temperature sensors, potentiometers, and light sensors commonly found in consumer and industrial embedded designs.
Is the PIC32MX170F256D-50I/PT appropriate for designs targeting industrial temperature environments?
Yes, the -50I suffix in PIC32MX170F256D-50I/PT indicates an industrial temperature grade, supporting operation across the -40°C to +85°C range. This makes the device suitable for factory automation controllers, outdoor instrumentation, and automotive-adjacent applications where ambient temperature can vary widely over the product lifetime.
How does the 44-pin TQFP package of the PIC32MX170F256D-50I/PT compare to other PIC32MX170 package options for board space?
The 44-pin TQFP (TQFP-44) is a compact quad flat package with fine-pitch leads on all four sides, offering more I/O pins in a smaller footprint compared to DIP alternatives while remaining hand-solderable for prototyping. Compared to the 44-pin QFN variant, the TQFP-44 is easier to inspect visually and rework, making it a practical choice for low-to-medium volume production of PIC32-based control boards.
