Frequently Asked Questions
How do the DMA channels on PIC32MX120F032B-I/SO improve data throughput in embedded applications?
The PIC32MX120F032B-I/SO includes DMA channels that allow peripherals such as UART, SPI, and ADC to transfer data directly to or from RAM without CPU involvement. This frees the 40 MHz PIC32 core to execute control algorithms or communication tasks while DMA handles burst data movement, enabling sustained ADC sampling at high rates alongside real-time serial communication — a capability particularly valuable in data logging, audio buffering, and sensor-fusion embedded designs.
For a 32-bit upgrade from an 8-bit PIC in a 28-pin SOIC design, how compatible is PIC32MX120F032B-I/SO?
The PIC32MX120F032B-I/SO is housed in a 28-pin SOIC package (17.9 mm x 7.5 mm, 1.27 mm pitch), which shares the standard SOIC-28 footprint used by many 8-bit PIC18 and AVR devices. Designers migrating from 8-bit MCUs can often reuse the same PCB land pattern while gaining a 32-bit MIPS core at 40 MHz, DMA support, and a larger address space — requiring only firmware updates rather than full board redesigns, which substantially reduces upgrade development cost.
Does PIC32MX120F032B-I/SO support JTAG boundary scan and how does it help in production testing?
Yes. The PIC32MX120F032B-I/SO supports JTAG boundary scan, allowing automated test equipment to drive and observe all I/O pins through the 4-wire JTAG interface during in-circuit test. Boundary scan vectors can verify solder joint continuity across all 28 pins without physical probing needles, shortening ICT fixture cost and test cycle time on PCBs with densely placed SMD components. This capability is especially beneficial in production environments where SOIC-28 PCB real estate is limited and probe access to individual pads is restricted.
