8-bit MCUs strengthen code protection
Microchip’s PIC18-Q24 MCUs employ a programming and debugging interface disable (PDID) function that enhances chip-level security. When enabled, this enhanced code protection feature disables the programming/debugging interface and blocks unauthorized attempts to read, modify, or erase firmware.
The PIC18-Q24 microcontroller family also provides a multi-voltage I/O (MVIO) interface. MVIO allows the MCU to interface with digital inputs or outputs at different operating voltages. This integrated level shifting not only eliminates the need for external level shifters, but also reduces both design area and BOM costs. MVIO pins support a voltage range of 1.62 V through 5.5 V.
With PDID and MVIO, PIC18-Q24 8-bit MCUs are particularly useful as system management processors, performing monitoring and telemetry for a larger processor. These routine tasks are typically most vulnerable to potential hackers as they attempt to gain access to embedded systems.
Other features of the PIC18-Q24 include a 10-bit ADC with computation capable of 300 ksamples/s and an 8-bit signal routing port to interconnect digital peripherals without using external pins. The PIC18-Q24 devices are available in a variety of packages with pins counts ranging from 28 to 48 pins.
