More about Dediprog Technology Co. Ltd

DediProg Technology Co. Ltd., founded in 2005 in Taiwan, is a leading manufacturer of IC programming devices. They specialize in automated and manual IC programmers, test sockets, and solutions for various types of memory chips and microcontrollers. With a global presence, DediProg serves customers worldwide, offering efficient and accurate chip programming solutions for technical users.

Dediprog: SPI flash programmers, emulators and gang programmers

Dediprog Technology builds SPI flash programmers, SPI flash emulators and universal gang programmers for firmware engineers. The SF series programs SPI NOR and SPI NAND flash either in-system on the target board or in a socket, the EM100Pro emulator replaces the flash chip so firmware and BIOS images can be changed in seconds, and the NuProg range programs UFS, eMMC and other devices on the bench or in production.

In-system and socket programming with the SF series

In-system programming (ISP) means updating the SPI flash while it stays soldered on the target board. The Dediprog SF600Plus-G2 and Dediprog SF100 connect to the PC over USB and to the board through an ISP cable, test clip or header. With a socket adaptor the same flash can be programmed off-board, and the SF600Plus-G2 can also run stand-alone from its own memory using a start button.

The same programmer family serves both routes: clip onto the board for ISP, or use a socket adaptor for off-board programming.

How flash emulation works

The EM100Pro-G3 SPI NOR flash emulator lets a target system boot from an image held in the emulator's DRAM instead of from a real flash chip. The emulator takes the place of the flash on the board, the target boots from the emulated image, and a new image is loaded from the PC without erasing or reprogramming a device. Dediprog quotes about 10 seconds for a 1 Gb image on the Dediprog EM100Pro-G3, against several minutes for conventional programming.

The emulator stands in for the flash chip, so each firmware change is a file load rather than an erase and program cycle.

Earlier emulators are also listed: the EM100Pro-G2 and the EM100Pro.

Specifications and supported interfaces

SPI modes: the SF600Plus-G2 supports single, dual, quad and octal I/O; the EM100Pro-G3 emulates single, dual and quad I/O at up to 50 MHz.
Voltage: the EM100Pro-G3 supports 1.8 V and 3.3 V; the SF600Plus-G2 supports 1.2 V low-voltage devices.
Protection: the SF100 and SF600Plus-G2 include signal conflict protection, which guards against contention when the target board drives the SPI lines.
Host connection: USB 2.0 for the SF600Plus-G2 and EM100Pro-G3; USB 3.0 for the NuProg engineering and gang programmers.
File formats (NuProg range): binary, Intel Hex and Motorola S-record.
UFS and eMMC (NuProg range): UFS LUN configuration, descriptors, attributes and flags; eMMC user area, boot partitions and Extended CSD.

Software and tools

The SF programmers share one software package, with three ways of working. Engineering mode is an interactive GUI with automatic chip detection, Production mode runs several programmers at once from stored project files, and the command-line tool DpCmd suits scripted and automated test stations.

DediProg Engineering: chip detection, read, erase, program and verify with real-time editing.
Production mode: multi-programmer control with project files (.sfprj); batch sequences run blank check, erase, program and verify.
DpCmd: command-line options include detect, read, program, smart update (sector-level comparison) and erase, with options for VCC and SPI clock.
EM100Pro software: image loading, SPI protocol analyzer and SPI HyperTerminal for the EM100Pro-G3.
DediWare: software for the NuProg engineering and gang programmers.

Typical applications

Updating or recovering BIOS and firmware flash on a populated board without desoldering
BIOS and bootloader development, where the EM100Pro-G3 removes the erase and program cycle between builds
Production-line programming with multiple SF programmers or a NuProgPlus gang programmer
Engineering and duplication work on UFS and eMMC storage (NuProgPlus-U16)

Frequently asked questions

What is the difference between ISP and socket programming?

In-system programming (ISP) updates the SPI flash while it is soldered on the board, using an ISP cable or test clip. Socket programming uses a socket adaptor, so the chip is programmed off the board. The SF600Plus-G2 supports both, and the SF100 is aimed at on-board programming.

Which Dediprog programmer should I choose?

Choose the SF600Plus-G2 if you need SPI NAND, octal I/O, 1.2 V devices or stand-alone operation. The SF100 suits SPI NOR in-system programming. For UFS, eMMC, MCUs and multi-site production use, look at the NuProg-E2, NuProgPlus-U8 and NuProgPlus-U16.

What does the EM100Pro-G3 do that a programmer does not?

The EM100Pro-G3 emulates the SPI flash from DRAM, so the target boots from the emulated image and a new image loads without erasing or programming a chip. It also includes an SPI protocol analyzer that logs the commands and data on the SPI bus.

Which flash sizes can the EM100Pro-G3 emulate?

The EM100Pro-G3 emulates SPI NOR flash from 512 Kbit to 4 Gbit at 1.8 V or 3.3 V, with single, dual and quad I/O at up to 50 MHz. Check the product page and your flash datasheet for adaptor requirements.

Which software do Dediprog programmers use?

The SF series uses DediProg software with Engineering mode, Production mode and the DpCmd command-line tool, the EM100Pro-G3 has its own EM100Pro software, and the NuProg range uses DediWare. Check the product page for the current version and licensing for your model.

Do I need an adaptor or cable?

Usually yes. ISP programming needs an ISP cable, header or test clip to match your board and package, and socket programming needs an adaptor for the chip package. Ask our engineers if you are unsure which cable or clip your board needs.
