Frequently Asked Questions
How much flash and RAM does PIC32MX120F064H-I/MR provide, and is it sufficient for an RTOS?
The PIC32MX120F064H-I/MR includes 64KB of program flash and 8KB of SRAM, plus a 3KB boot flash region. This is adequate to run lightweight RTOS kernels such as FreeRTOS with a minimal task set, leaving approximately 40KB to 50KB for application code, which covers sensor polling, communication stacks, and simple UI logic.
Which audio designs benefit from the I2S peripheral on the PIC32MX120F064H-I/MR?
The I2S interface on the PIC32MX120F064H-I/MR connects directly to stereo DACs and audio codecs operating at standard sample rates such as 44.1kHz and 48kHz. This makes it suitable for portable MP3 players, voice-prompt modules, and industrial alarm annunciators where 16-bit or 24-bit audio output is required without an external audio processor.
How does the CTMU on PIC32MX120F064H-I/MR enable capacitive touch sensing without external ICs?
The Charge Time Measurement Unit (CTMU) on the PIC32MX120F064H-I/MR sources a precise current to charge a capacitive electrode and measures the resulting voltage with the on-chip ADC, detecting finger proximity changes as small as a few picofarads. This eliminates the need for a dedicated touch controller IC in designs with up to 16 capacitive buttons or sliders.
What debugging and programming options does the PIC32MX120F064H-I/MR QFN-64 support?
The PIC32MX120F064H-I/MR supports JTAG boundary scan and ICSP (In-Circuit Serial Programming) through a 2-wire interface, allowing programming and debug with the PICkit or ICD tools. The 3KB dedicated boot flash protects the bootloader from accidental overwrite during application updates, reducing field service risks in deployed products.
