The power of the MiniProg3 lies in its hardware versatility, handling several distinct communication lines. SWD and JTAG Debugging
: Attaching the MiniProg3 to a running PSoC 3 or PSoC 5LP target via the 10-pin cable may cause the device to reset. psoc miniprog3
Operating natively as a USB Human Interface Device class tool, it eliminates the need for unstable custom kernel-level drivers across modern desktop operating systems. Hardware Interface Protocols The power of the MiniProg3 lies in its
For modern architectures like the PSoC 4 and PSoC 5LP, the MiniProg3 utilizes SWD. This protocol reduces the physical pin requirement down to two lines—Serial Wire Data (SWDIO) and Serial Wire Clock (SWDCLK)—while preserving full hardware execution control. For legacy PSoC 3 hardware or complex chain topologies, full JTAG implementations are actively supported via standard boundary scan techniques. I2C and SPI Bridging I2C and SPI Bridging : It can supply
: It can supply power to a target board at four selectable voltage levels: 1.8V, 2.5V, 3.3V, or 5V . Additionally, it can communicate with devices using I/O levels ranging from 1.5V to 5.5V. Technical Specifications & Hardware
