Equivalent
Direct equivalents outside Microchip don’t exist. The closest options are other variants of Microchip’s PIC32MX575F256L-80I family in different packages (same MCU, different packaging). For a pin-compatible cross or to find alternatives, use Microchip’s Product Selector/Cross Reference tool or contact a distributor. If none available, you may need a PCB redesign when switching vendors or packages.
