Northern Software’s NSDSP is a family of hardware programmers for PIC microcontrollers, positioned as fast and reliable PIC programming tools. It is intended not only for the development stage, but also for organized programming in production environments. The page states that it supports most PIC microcontrollers, although the captured text does not include a detailed device compatibility list.
NSDSP’s main strengths are its native, lightweight, and automation-friendly design. The accompanying free software provides native versions for Windows, Linux, and Mac, and the vendor specifically highlights that, unlike Java-based software, it does not introduce extra latency. The tools support both a graphical interface and a command-line interface: the former is suitable for day-to-day development and debugging, while the latter is better suited to scripted programming on production lines. All NSDSP programmers also include a UART interface, allowing communication between a PIC and a PC at up to 2 Mbaud.
The product provides free UART communication source code as well as a free interface library. The interface library covers programming, debugging, UART, SPI, bit banging, HEX file handling, and other capabilities, indicating that NSDSP is not merely a standalone programmer but can also be embedded into custom PC tools or automation workflows. Another useful design option is the ability to purchase a single NSDSP chip and install it directly on a production board, enabling in-field programming of the PIC without an additional dongle, while also serving as a low-cost USB-to-UART interface.
The text states that the software and interface library are free, and that NSDSP programmers and individual NSDSP chips are sold. Specific pricing details are not disclosed; it only mentions that the single-chip price is comparable to an FTDI chip. On the open-source side, the page only explicitly says that the UART communication source code is free. It does not state whether the full software, hardware design, or interface library is open source, so it should not be treated as a fully open-source solution.
The advantages include native cross-platform tools, support for both GUI and command-line operation, suitability for production automation, and relatively low-level interface library capabilities. NSDSP-3 uses a Spartan-7 FPGA, while NSDSP-1/2 use a PIC16F1454, reflecting a design philosophy that leans toward simplicity and efficiency. The main drawback is the lack of public information: pricing, documentation quality, support, the complete device compatibility list, and licensing boundaries are all unclear. It is best suited to PIC developers, embedded engineers, production programming teams, and manufacturers that want to integrate in-field programming capabilities directly into their product boards.
The captured text does not provide information on access from China, payment, or logistics, so availability can only be marked as unknown. If purchasing or payment is inconvenient, alternatives to consider include Microchip’s official PICkit/ICD series, as well as PIC programmers and production programming solutions available locally in China.
