PIC32MX795F512L-80I/PT

The PIC32MX795F512L-80I/PT is a high-end member of Microchip’s PIC32MX5xx/6xx/7xx family, combining a 32-bit MIPS M4K core at 80MHz with 512KB Flash and 64KB SRAM. It is distinguished by its rich connectivity: an IEEE 802.3-compliant Ethernet MAC with dedicated DMA, dual CAN 2.0B controllers, and USB 2.0 full-speed OTG with integrated PHY. A hardware cryptographic engine supports AES-128/192/256, DES, and 3DES for secure data transmission. These features make it a compelling single-chip solution for networked embedded systems in industrial, medical, and building automation markets.

The PIC32MX795F512L operates on a MIPS32 M4K RISC core with a 5-stage pipeline achieving 1.56 DMIPS/MHz. The core accesses Flash and SRAM through a multi-layer bus matrix supporting concurrent DMA and CPU transactions. The Ethernet MAC implements the MAC sublayer with DMA for zero-CPU-overhead frame transfer. CAN controllers handle the complete CAN 2.0B protocol with hardware message filtering and priority scheduling. The USB OTG module integrates the PHY, SIE, and DPLL for full-speed host and device operation. The crypto engine processes block ciphers in hardware, offloading the CPU during secure communication sessions.
