The LPC4322 has a built-in USB PHY, so the schematic is simple: USB D+ and D- lines go directly to the MCU with 22-ohm series resistors and pull-up/pull-down configuration for device detection.
The J-Link v9 hardware is a significant upgrade over the older v8, primarily moving to a faster and more stable 32-bit RISC CPU . jlink v9 schematic
Detailed PDFs and circuit diagrams can often be found on academic or document-sharing platforms: Course Hero hosts specific schematic files for the V9. The LPC4322 has a built-in USB PHY, so
Small 22-33 ohm resistors are placed on signal lines (TMS, TCK, TDO, TDI) to reduce ringing and signal reflection. Small 22-33 ohm resistors are placed on signal
The architecture is designed to provide high-speed debugging with speeds reaching up to and 15 MHz for SWD . Go to product viewer dialog for this item.
An external SPI flash chip might be present to store firmware, though the SAM3U often uses its internal flash.
