EM100Pro SPI Flash Emulator

Model Name : EM100Pro
Emulates ALL SPI NOR Flash in the market!

EM100Pro is DediProg Serial Flash Emulator based on RAM memory in order to offer the best update performances. This advanced tool has been designed in close cooperation with the Serial Flash suppliers to emulate the behaviors of all the market Serial Flash and also the next generation Serial Flash.

EM100pro emulator provides engineers with a flexible development and testing tool for any embedded project that uses an external SPI Flash. It provides quick, in-circuit firmware test cycles during development.

EM100pro increases productivity by downloading firmware code or data into the emulator in a few seconds for density as large as 512Mb. It further provides “SPI BUS Analyzer” feature by collecting all the SPI commands on the SPI bus in order to help for the debugging process.

EM100pro will speed up your firmware development and testing by eliminating the need to remove-erase-program and re-install SPI flash each time you test a code change.

If you want to stop the "program/insert/boot/remove/erase" cycle, then this is the tool for you.

The EM100Pro has two 2.54mm pitch males connectors of:

  • 2x2 for the Reset and Trig signals
  • 2x10 for the Emulation signals

EM100Pro is designed with ISP header, through an appropriate connector, users can connect the programmer and drive the SPI signals, supply the memory and control the controller or application status. Please refer to Table 1 for the EM100Pro 2x10 header pin out. 
DediProg also provides the EM100Pro ISP Cable which is used to connect the EM100Pro programmer to the 2X5 2.54mm ISP Pin Header on board, please refer to Table 2 for the EM100Pro ISP Cable 2x5 pin out.
