PIC32CX SG Family of Microcontrollers (MCUs)

Secure and Connected MCUs With Optional Hardware Security Modules (HSMs)

PIC32CX SG devices 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. Take advantage of the highest level of security in an MCU of its class.

These AEC-Q100 Grade 1-qualified MCUs come in three options, PIC32CX SG41, PIC32CX SG60 and PIC32CX SG61, with 100-pin and 128-pin packages in 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.
  • The SG61 adds a JIL High-certified secure Hardware Security Module (HSM) to the MCU. We offer it as a single in-line package, protecting your applications and secrets from physical attacks. We also provide custom provisioning options for the SG61.

Microchip Bootloaders

Bootloaders are used to upgrade firmware on a target device without using an external programmer or debugger. Commonly used with microcontrollers (MCUs), a bootloader contains code that loads and executes an application program. Bootloaders can also perform additional tasks such as validating the code integrity and authenticity.
