Algocraft WriteNow! 2 (WN-PRG02A) is a 2-site in-system programmer that programs 2 devices in true parallel on the assembled board. Each site can run its own image, and variable data such as serial numbers and MAC addresses can be different on every site in every cycle. It fits inside a test fixture, is controlled by an ATE or a PC, or runs standalone from projects on its memory card. Pertech is an Algocraft distributor.
WriteNow! 2 highlights
- 2 programming sites, true parallel programming
- Each site can run its own image; per-site serial numbers, MAC addresses and production codes
- Microcontrollers, serial and parallel memories, CPLDs and other programmable devices
- JTAG, SWD, SPI/QSPI, I2C, UART, BDM, SWIM, ICSP, UPDI, SBW and many more protocols
- Programmable I/O voltage 1.6 to 5.5 V, high-speed I/O, EOS/ESD protection
- Isolated LAN, isolated RS-232, USB and an isolated low-level interface for ATE control
- Standalone operation from projects on the built-in memory card
- SDK/API for Visual C, Visual Basic, C# and LabVIEW, plus an ASCII command protocol
- Expands to more ISP channels with a demultiplexer module (up to 8)
Where the WriteNow! 2 fits
- In-circuit and functional test stations (Keysight, Teradyne, TRI, SPEA, SEICA)
- Panels of boards programmed in one cycle
- Automotive production with PSI5 and differential-bus adapters
- Lines that need serial numbers, MAC addresses or calibration data per board

Frequently asked questions
What is the WriteNow! 2 WN-PRG02A?
It is an Algocraft in-system programmer with 2 programming sites that work in true parallel, for programming devices on the assembled board in production.
Can each site program a different image?
Yes. A programming command runs a project on the sites you select, so different sites can run different projects, and variable data such as serial numbers can be different for each site. Over the low-level interface, PRJ_SEL lines select the project and START_ENA lines enable each site.
Can I add more channels?
Yes. Algocraft demultiplexer modules multiply the ISP lines: WN-DM2X2A (4 channels), WN-DM2X3A (6), WN-DM2X4A (8).
How is it controlled on the production line?
Standalone with the START line, from a PC with the Algocraft software, or from an ATE through isolated LAN, RS-232 or the low-level interface, using the ASCII command protocol or the SDK for Visual C, Visual Basic, C# and LabVIEW.
Which WriteNow! model do I need?
Pick the number of sites to match the boards you program per cycle: WriteNow! (1 site, relay barrier built in), WriteNow! 2, 4 or 8. All models share the same software and projects, and the single-site µISP is compatible with them for lab work.
