SPI NOR Flash Emulator for Firmware Development
The EM100Pro-G3 is a device emulator, not a programmer. It connects in place of the SPI NOR flash and presents itself to the target as that flash, with the image held in the emulator's own DRAM. A code change is a download to the emulator, not an erase, program and verify cycle on a real chip.
Key Features
Fast image loading. Dediprog quotes 3 s to load a 256 Mb image, 5 s for 512 Mb, 10 s for 1 Gb and 20 s for 2 Gb.
SPI bus analyser. Records the SPI commands and data on the bus in an internal trace buffer, so you can see what the target reads at boot. At high bus throughput the buffer can overflow, so very busy traces may have gaps.
SPI HyperTerminal. A two-way channel over the SPI bus for debug messages between the target and the host PC.
Voltage and bus support. 1.8 V and 3.3 V devices; single, dual and quad I/O; SPI clock up to 50 MHz; device densities from 512 Kbit to 4 Gbit.
Device selection in software. Pick the SPI NOR part to emulate from the Dediprog software list, so code can be tried against different flash parts without changing hardware.
Connections. A 2x10 header carries the emulation signals and a 2x2 connector carries reset and trigger. Cables and adaptors connect it to the board; an Intel motherboard adaptor is available as an option.
Performance Comparison
| Density | Programmer | EM100Pro-G2 | EM100Pro-G3 |
|---|---|---|---|
| 256 Mb | 115 s | 5 s | 3 s |
| 512 Mb | 200 s | 10 s | 5 s |
| 1 Gb | N/A | 20 s | 10 s |
| 2 Gb | N/A | 40 s | 20 s |
Dediprog's figures. The programmer times are erase, program and verify on a real device with a conventional programmer; Dediprog does not name the model.
Applications
Firmware and BIOS development where the image changes many times a day, boot debugging where you need to see what the target reads from flash, and trying code against several SPI NOR parts without changing hardware. Production boards still need their flash programmed with a programmer.

Questions and Answers
-
What Connectivity Options and Mechanical Considerations Apply to PCB Integration?
The EM100Pro-G3 has two connectors: a 2x10 ISP header for emulation signals and a 2x2 connector for reset and trigger.
Both are standard 2.54mm pitch male connectors, so they suit common PCB layouts and connect directly to DediProg's ISP cables. Other cables and adaptors are available for different PCB configurations, plus optional Intel motherboard support through specific ISP-ADP-Intel-C adaptors.
The unit measures 137 x 78 x 16mm and weighs 125g.
-
Can the EM100Pro-G3 Replace Physical SPI Flash Devices During Prototype Development?
Yes. During prototyping and early development the EM100Pro-G3 can stand in for the SPI flash: the target sees it as an SPI NOR flash device.
You can change firmware and test code configurations without the delay and wear of programming a physical flash, and the built-in protocol analysis shows what the target does on the bus.
-
How Does the SPI HyperTerminal Interface Help Embedded System Debugging?
The EM100Pro-G3's SPI HyperTerminal interface creates a two-way channel between your embedded application and the host PC.
You can add debug messages to your firmware that send diagnostic information over the SPI bus to the HyperTerminal window, with no extra hardware interface. Messages follow Dediprog's defined format. Host PC applications can also send commands back to control the target firmware, all through the SPI interface.
-
What Software and Operating System Support Does the EM100Pro-G3 Have?
The EM100Pro-G3 runs on Windows. Dediprog supplies USB drivers for Windows XP and for Windows 8, 8.1 and 10.
DediProg supplies the EM100Pro-G3 Software, USB drivers and documentation. It loads binary images; the command-line tool can save read-back data as bin, hex or s19. It connects over USB 2.0.
-
In What Scenarios Does the EM100Pro-G3 Give the Most Development Value?
The EM100Pro-G3 gives most value where code changes often, such as debugging boot sequences, testing firmware configurations or validating SPI NOR Flash-based applications that need frequent changes.
It suits teams developing IoT devices, automotive embedded systems and industrial control applications with rapid prototyping cycles. It's also useful in education and research, giving hands-on SPI flash experience without the constraints and cost of traditional programming.
-
How Does Automatic Voltage Selection Help Development?
The EM100Pro-G3 sets its I/O level to 1.8 V or 3.3 V automatically from the flash model you select in the software, so no re-plugging is needed (the original EM100Pro needed manual selection). It also monitors the target's VCC and keeps its outputs off until the target has powered up.
-
Why Use the EM100Pro-G3 Instead of Reprogramming SPI NOR Flash?
The EM100Pro-G3 is a device emulator, not a programmer. It connects in place of the SPI NOR flash, and the target sees it as the real part, while the image sits in the emulator's DRAM. Changing the code means loading a new image into the emulator, so there's no chip to reprogram, pull or refit.
Dediprog quotes 3 s to load a 256 Mb image, 5 s for 512 Mb and 10 s for 1 Gb. For a conventional programmer to erase, program and verify a real device, it quotes 115 s at 256 Mb and 200 s at 512 Mb.
The built-in SPI bus analyser logs the commands and data on the bus, so you can see what the target reads at boot. Emulation runs at up to 50 MHz, so the target's SPI clock should not exceed that while emulating. Production boards still need their flash programmed, so the EM100Pro-G3 speeds up development work, not production.
-
What Debugging Capabilities Does the Integrated SPI Protocol Analyser Provide?
The EM100Pro-G3's built-in SPI Protocol Analyser captures SPI commands, data transfers and timing information in a dedicated 512MB high-speed internal buffer. This shows the communication between the host controller and the emulated flash device.
You can monitor SPI traffic in real time, find communication bottlenecks, validate command sequences and troubleshoot timing issues without an external protocol analyser. It supports both live monitoring during code execution and post-analysis of captured data.
-
Which Flash Memory Densities and Interface Types Does the EM100Pro-G3 Support?
The EM100Pro-G3 supports SPI NOR Flash densities from 512Kbit to 4Gbit.
- Single I/O, Dual I/O and Quad I/O modes, with clock frequencies up to 50MHz
- 1.8 V and 3.3 V operation, with the voltage set automatically from the selected flash model
- Standard SPI commands
- Next-generation flash specifications developed with leading SPI NOR Flash suppliers
