Frequently Asked Questions
How does the PIC32MX440F128H-80I/PT handle USB connectivity, and what speeds does it support?
The PIC32MX440F128H-80I/PT integrates a full-speed USB 2.0 OTG controller supporting both host and device modes at 12 Mbit/s. This allows it to connect directly to USB peripherals such as flash drives and HID devices in host mode, or enumerate as a USB device to a PC, without needing an external USB bridge chip. The on-chip USB transceiver further reduces BOM cost.
For a CAN-based industrial sensor node, does the PIC32MX440F128H-80I/PT provide enough on-chip memory to run a CAN stack and application firmware?
Yes, the PIC32MX440F128H-80I/PT provides 128KB of Flash program memory and 32KB of RAM. A compact CANopen or NMEA 2000 stack typically occupies 20KB to 40KB of Flash, leaving 80KB or more for application logic, lookup tables, and firmware update images. The 32KB RAM is adequate for message buffers, OS task stacks, and sensor data queues in a typical node design.
What is the maximum CPU clock frequency of the PIC32MX440F128H-80I/PT, and how does that compare to similar 32-bit PIC devices?
The PIC32MX440F128H-80I/PT operates at up to 80MHz using its internal oscillator with PLL, delivering 80 DMIPS of sustained throughput with the 1.56 DMIPS/MHz rated MIPS M4K core. This places it above entry-level PIC32MX1xx/2xx devices clocked at 50MHz and on par with PIC32MX5xx/6xx/7xx families, while its smaller Flash and pin count keep unit cost lower for medium-complexity designs.
Is the 64-pin UQFN package of the PIC32MX440F128H-80I/PT suitable for high-density PCB layouts, and what pitch does it use?
The 64-pin UQFN package uses a 0.5mm pin pitch, enabling a very compact PCB footprint relative to a standard TQFP-64 package with 0.8mm pitch. The exposed thermal pad on the bottom also improves heat dissipation. This makes the PIC32MX440F128H-80I/PT well suited for multilayer boards in portable medical devices, wearables, and handheld industrial scanners where board real estate is limited.
