What are the key features of PIC32MX220F032B-I/SP?

  • 40 MHz 32-bit MIPS M4K core delivering 50 DMIPS for computationally demanding embedded tasks
  • 35 KB Flash and 8 KB SRAM with DMA controller enabling efficient peripheral-to-memory data transfers
  • Full-speed USB 2.0 device/OTG controller integrated for direct USB connectivity without external silicon
  • 28-pin SPDIP through-hole package enabling breadboard prototyping and socketed board development

What is PIC32MX220F032B-I/SP used for?

The PIC32MX220F032B-I/SP suits USB-enabled data acquisition devices, HID peripherals, and low-cost industrial sensor nodes where a 32-bit MIPS core at 40 MHz delivers substantially more throughput than 8-bit alternatives without increasing BOM cost significantly. Its DMA controller offloads peripheral data movement from the CPU, making it effective for audio playback, SPI display driving, and continuous ADC sampling in portable instruments. Engineers appreciate the familiar 28-pin SPDIP form factor for rapid breadboard prototyping during early development before transitioning to surface-mount production layouts.

Frequently Asked Questions

How does the PIC32MX220F032B-I/SP's 32-bit MIPS core at 40 MHz compare to an 8-bit PIC18 at the same clock speed?

The 32-bit MIPS M4K core in the PIC32MX220 processes 32-bit data in a single instruction, delivering approximately 50 DMIPS at 40 MHz compared to roughly 10 MIPS on an 8-bit PIC18 at the same clock. This 5× effective throughput advantage is critical for tasks such as floating-point math, FFT computation, and USB protocol handling that would require dozens of 8-bit instructions per operation.

What USB capability does the PIC32MX220F032B-I/SP offer, and what device classes can it support?

The device integrates a full-speed USB 2.0 (12 Mbps) device and OTG controller with on-chip transceiver, eliminating the need for an external USB bridge chip. Using Microchip's Harmony middleware stack, it supports HID, CDC, MSD, and audio device classes, enabling USB keyboard emulators, virtual COM ports, mass storage interfaces, and simple audio devices within a single 28-pin chip.

For a 28-pin DIP prototype, what memory resources does the PIC32MX220F032B-I/SP provide compared to PIC18F in the same package?

The PIC32MX220 offers 32 KB program Flash, 3 KB boot Flash (35 KB total), and 8 KB SRAM in the same 28-pin footprint as a PIC18F2320 which has only 8 KB Flash and 512 bytes SRAM. The four-fold increase in program memory and sixteen-fold increase in SRAM allow significantly more complex firmware such as a RTOS kernel, a USB stack, and application logic to coexist in a single chip.

How does the integrated DMA controller in PIC32MX220F032B-I/SP benefit SPI peripheral interfacing?

The DMA controller can autonomously transfer data between the SPI transmit and receive buffers and SRAM at up to 40 million transfers per second, freeing the CPU from polling or interrupt-driven byte handling. For an SPI-driven LCD with a 240 × 320 pixel buffer, DMA-driven frame updates complete in approximately 2 ms at 40 MHz SPI clock while the CPU continues executing application logic uninterrupted.
