Frequently Asked Questions
How does the PIC32MX320F128H-80I/PT's 80 MHz MIPS core compare to 8-bit PIC MCUs for control loops?
The PIC32MX320F128H runs a 32-bit MIPS M4K core at up to 80 MHz, delivering significantly higher throughput than 8-bit PIC devices, which typically run at 4 MHz to 32 MHz. This enables faster PID control loops, more complex state machines, and richer communication stacks in the same physical footprint.
What memory is available on the PIC32MX320F128H-80I/PT for firmware and data buffers?
The device provides 128 KB of on-chip Flash for program storage and 16 KB of SRAM for runtime data, stack, and DMA buffers. This is sufficient for mid-complexity firmware including FreeRTOS, basic USB stacks, and multi-channel ADC data logging at 80 MHz.
Which communication interfaces does the TQFP-64 package expose for connecting sensors and peripherals?
In the 64-pin TQFP package, the PIC32MX320F128H exposes SPI, I2C, UART, and USB 2.0 FS interfaces, along with up to 5 GPIO ports. This variety supports concurrent sensor communication, display driving, and host USB connectivity in a single 64-pin device.
What temperature range does the -80I/PT suffix cover and is the device RoHS compliant?
The -80I/PT suffix designates the industrial temperature grade from -40°C to +85°C in a TQFP-64 package. The device is RoHS and lead-free compliant as indicated by the Pbfree code, meeting modern environmental directives for industrial and commercial deployments.
