Microchip Technology PIC32CX SG41/SG60/SG61 Advanced Security MCUs

Microchip Technology PIC32CX SG41/SG60/SG61 Advanced Security Microcontrollers (MCUs) are high-performance MCUs with a 32-bit Arm® Cortex®-M4 processor with Floating Point Unit (FPU). These devices run up to 120MHz, 1MB of Dual Panel Flash with ECC, and 256KB of SRAM with ECC. It also adds a 10/100 Ethernet MAC and 2 CAN-FD ports targeted for industrial automation, automotive applications, and general-purpose applications requiring wired connectivity. Flash has an OTP region that is used for developing immutable secure boot. It also offers secure debug, chip erase protection, IP Protection, and Boot Protect feature.

The Microchip Technology PIC32CX SG41/SG60/SG61 series MCUs offer excellent features with class-leading power performance and integrated hardware security.
