Microchip PIC32CX SG Microcontrollers (MCUs)
Secure and connected MCUs with optional hardware security modules (HSMs)
Microchip features their PIC32CX SG devices, which are mid-performance, 120 MHz microcontrollers (MCUs) that combine connectivity, performance, and industry-leading integrated security options to power industrial, IoT, automotive and other applications.
For design flexibility, the PIC32CX1025SG41080 family is available in an 80-pin Wafer Level Chip Scale Package (WLCSP).
Microchip also offers three AEC-Q100 Grade 1-qualified versions of the PIC32CX SG41, PIC32 SG60 and PIC32CS SG61 MCUs that are available in 100- and 128-pin packages and support extended temperature ranges.
The SG41 is a stand-alone MCU that offers excellent connectivity and security features including immutable secure boot, secure debug and code protection from chip erase.
