Frequently Asked Questions
What clock speed does PIC32MX320F032H-40I/MR achieve and how does that affect real-time control loop timing?
The PIC32MX320F032H-40I/MR runs its MIPS M4K core at up to 40 MHz, allowing a 25 ns instruction cycle. At that speed, a simple PID control loop can typically execute within 10 µs, making it practical for mid-speed motor control and sensor fusion tasks.
Which communication buses are available on PIC32MX320F032H-40I/MR for connecting peripherals in an industrial node?
The device includes USB 2.0 OTG, 2 CAN 2.0B modules, 2 SPI ports, 2 I2C ports, and 6 UART channels. This multi-bus support lets designers connect a CAN fieldbus, an RS-485 network, and an SPI display simultaneously from a single 64-pin device.
How does the QFN-64 package of PIC32MX320F032H-40I/MR compare to TQFP-64 for high-density PCB layouts?
The 9 mm × 9 mm QFN-64 body is smaller than a standard 10 mm × 10 mm TQFP-64 footprint, saving roughly 19% board area. The exposed thermal pad also improves thermal dissipation, which matters when the MCU runs sustained tasks at 40 MHz.
Is PIC32MX320F032H-40I/MR RoHS-compliant and lead-free for export to regulated markets?
Yes, the I/MR variant is fully RoHS-compliant and Pb-free. The -40°C to +85°C industrial temperature rating makes it suitable for CE-marked equipment sold in European markets without lead exemptions.
