Frequently Asked Questions
How does the USB 2.0 OTG capability of the PIC32MX420F032H-40I/PT simplify USB host and device designs?
The PIC32MX420F032H-40I/PT integrates a USB 2.0 Full-Speed OTG controller directly on the die, operating at 12 Mbps in both host and device roles without an external USB bridge IC. In device mode it enumerates as a CDC, HID, or mass-storage class device with no external USB transceiver beyond a 1.5kΩ pull-up resistor. In host mode it powers a downstream USB peripheral through VBUS, controlled by a GPIO pin, enabling data transfer from USB flash drives or keyboards in field data loggers.
What CAN network data rates and filtering does the PIC32MX420F032H-40I/PT support for automotive applications?
The PIC32MX420F032H-40I/PT CAN 2.0B module supports bit rates from 40 kbps up to 1 Mbps, configured by the baud-rate prescaler and time-quantum registers. It provides 8 programmable acceptance filter masks operating on 11-bit standard and 29-bit extended frame identifiers, allowing the 40 MHz CPU to wake only on frames relevant to the node while discarding the rest in hardware. Two dedicated receive buffers prevent message loss during back-to-back frame reception on a 500 kbps body CAN bus.
How much total Flash and RAM does the PIC32MX420F032H-40I/PT provide for firmware and runtime data storage?
The PIC32MX420F032H-40I/PT provides 32KB of program Flash plus 12KB of boot Flash for a total of 44KB of non-volatile code storage, alongside 8KB of data SRAM. The 12KB boot segment supports a secure bootloader that can update the main 32KB application Flash over USB or UART without erasing the bootloader itself. 8KB SRAM accommodates typical RTOS task stacks and sensor data buffers in compact 32-bit embedded applications running at 40 MHz.
When should a designer choose the PIC32MX420F032H-40I/PT over an 8-bit PIC18 device for an industrial panel controller?
The PIC32MX420F032H-40I/PT delivers 40 DMIPS from its 32-bit MIPS core compared to roughly 4 MIPS from a PIC18 at 64 MHz, a 10x throughput advantage that benefits applications running an RTOS, a USB stack, and a CAN protocol stack simultaneously. Its 32KB Flash supports larger firmware images with a full USB descriptor table and CAN middleware that would not fit in a PIC18's typical 16KB to 64KB Flash without significant optimization, while the 64-pin TQFP provides 5 more I/O pins than a PIC18F with the same package pitch.
