What are the key features of PIC32MX220F032B-50I/ML?
- 50 MHz MIPS32 core with 32 KB Flash and 8 KB RAM delivers real-time control performance in a compact 28-pin VQFN-28 QFN footprint
- Integrated USB peripheral and JTAG boundary scan (IEEE 1149.1) streamline firmware debugging and USB HID/CDC application development
- 3 KB dedicated boot Flash enables secure field firmware updates via bootloader without overwriting application code in the main 32 KB program space
What is PIC32MX220F032B-50I/ML used for?
PIC32MX220F032B-50I/ML is used in USB HID peripherals, embedded human-machine interfaces, and IoT sensor gateways where a 32-bit MIPS core running at 50 MHz provides sufficient processing power for protocol parsing and real-time data logging. Its 28-pin VQFN-28 package suits space-constrained wearable monitors and handheld measurement instruments requiring USB connectivity without an external USB bridge chip. Industrial fieldbus adapters and motor parameter loggers also leverage its ADC inputs and JTAG debug port for rapid bringup and field calibration.

Frequently Asked Questions
What clock speed and memory does PIC32MX220F032B-50I/ML offer for real-time embedded tasks?
PIC32MX220F032B-50I/ML runs a 32-bit MIPS core at up to 50 MHz, backed by 32 KB of program Flash and 8 KB of data RAM. At 50 MHz the core executes most instructions in a single cycle, yielding approximately 50 DMIPS of throughput, which is adequate for real-time PID control loops, USB packet parsing, and concurrent ADC sampling at rates up to 1 Msps.
How does the 3 KB boot Flash in PIC32MX220F032B-50I/ML support field firmware updates?
The 3 KB boot Flash region is a dedicated, independently addressable memory space that can hold a persistent USB or UART bootloader separate from the 32 KB application Flash. Because the bootloader resides in a different physical memory area, a field firmware update can erase and reprogram the full 32 KB application region without risking corruption of the bootloader itself, enabling safe over-the-air or USB-connected updates in deployed equipment.
Which USB-based embedded applications can PIC32MX220F032B-50I/ML serve as a direct controller?
PIC32MX220F032B-50I/ML integrates a full-speed USB 2.0 peripheral supporting device, host, and OTG modes at 12 Mbps. This makes it suitable as a direct USB HID game controller, USB CDC virtual COM port adapter, or USB audio class device without a separate USB bridge IC. The 50 MHz MIPS core handles USB enumeration, HID report assembly, and application logic concurrently, which external USB-to-UART bridge chips operating at 12 MHz cannot match for response latency.
When is PIC32MX220F032B-50I/ML a cost-effective upgrade path from 8-bit PIC16 or PIC18 designs?
PIC32MX220F032B-50I/ML becomes cost-effective when the application outgrows 8-bit arithmetic, requires USB connectivity, or needs more than 8 KB of Flash. The 32-bit MIPS architecture computes 32-bit multiply in 1 clock versus 4–8 clocks on a PIC18, and the 32 KB Flash fits complete communication stacks like USB-CDC or Modbus RTU that would require external memory on a PIC18 with 16 KB Flash. The VQFN-28 package is also only marginally larger than a PIC18F24K22 in a 28-pin SOIC, keeping the board area impact minimal.
