Applications
The PIC32MX220F032B-I/ML suits USB-enabled embedded applications such as HID devices, virtual COM port adapters, and USB data loggers that need a 32-bit processor in a compact 28-pin QFN footprint. Its DMA engine and 40 MHz MIPS core make it effective for audio playback, sensor fusion, and communication gateway designs where simultaneous peripheral management and data processing are required. The device is also well-suited for portable instruments and IoT bridge nodes that benefit from USB connectivity combined with low pin count and 3.3 V operation.

Frequently Asked Questions
Does PIC32MX220F032B-I/ML include USB support, and what transfer speed does it achieve?
Yes, the PIC32MX220F032B-I/ML integrates a USB 2.0 full-speed transceiver supporting up to 12 Mbps data transfer for device and host operation. This on-chip USB peripheral eliminates the need for an external USB controller IC, reducing BOM cost and board space in USB HID, CDC virtual COM, or mass-storage applications built around the 28-pin QFN package.
How does the DMA controller on PIC32MX220F032B-I/ML improve real-time data-logging performance?
The DMA controller on PIC32MX220F032B-I/ML transfers data between peripherals and RAM without CPU intervention, allowing the 40 MHz MIPS core to continue executing application code while ADC samples, SPI frames, or UART bytes are moved automatically. In a data-logging scenario, this reduces interrupt latency overhead and allows sustained sample rates that would otherwise stall the CPU when buffering to an SPI Flash device.
When would PIC32MX220F032B-I/ML be chosen over a PIC24 device for the same 28-pin form factor?
PIC32MX220F032B-I/ML provides a 32-bit data path, on-chip USB 2.0 at 12 Mbps, and a DMA controller — none of which are available on the 16-bit PIC24F family in the same 28-pin QFN footprint. Designers choose the PIC32 variant when the application requires USB connectivity, faster 32-bit arithmetic for DSP or protocol parsing, or DMA-driven SPI or UART transfers that exceed what a 16-bit architecture can handle efficiently.
