Prostoj spi flash programmator11/8/2022 ![]() This adapter is an external plug-in that can be purchased when needed. The only adapter needed is a footprint or rewiring adapter to go from 8 or 16-pin SPI Flash footprint to the 50-pin PROMJet header. This feature provides for better signal integrity and ease of use since the user does not have to worry about supplying the external SPI adapter with power or having the wrong setup to do SPI Flash emulation. Also there is no external adapter needed to translate the SPI signals into parallel Flash mode. A single PROMJet device can be set by the end user to run in parallel Flash or SPI Flash mode by simply choosing the appropriate bus format in the host software. Unlike other emulators that provide a translation adapter to plug into an existing Flash emulator, PROMJet SPI engine is built inside the unit by the optional SPI interface module (OPT-SPI). All address and data information is shifted serially into or out of the flash chip using these 2 signals. Unlike parallel Flash memory that uses address and date bus that must be modified when upgrading a Flash chip, SPI Flash memory uses only a Data-In and a Data-Out signals. ![]() #PROSTOJ SPI FLASH PROGRAMMATOR SERIAL#Since SPI Flash memory uses serial data to access Flash contents, it offers the user the ability to upgrade Flash features or Flash memory size to a higher memory capacity without changing the chip footprint on the board. ![]() It was the first Flash emulator to offer this feature. With the increasing popularity of SPI Flash memory, PROMJet added SPI Flash support in early 2004. ![]()
