DESCRIPTION
The Universal Serial Flash Development Kit (SFK-UNI) from NexFlash is a simple and cost effective solution for system designers interested in learning about and designing with NexFlash Serial Flash products. The SFK and associated accessories provide the basic hardware and software needed to develop with and program NexFlash 25Fxxx SPI and 26Fxxx NXS Serial Flash Memories and removable Serial Flash Modules (SFMs).
The SFK-UNI hardware includes an SFM-Port Adapter (that connects to the parallel port of a PC), a parallel port cable, batteries, and sample SFMs and SFM connectors. The SFM Port Adapter supports 3V and 5V, SPI and NXS Serial Flash Modules. Optional Socket Cards can be inserted into the SFM Port Adapter to support development and programming of alternate packages such as TSOPs, Smard Cards or custom modules. The Socket Card also provides convenient test points for probing signals during development. Using SFMs when prototyping, rather than surface mount packages, can greatly simplify the development process. SFMs can easily be moved between the prototype and the SFK for quick interrogation and modification.
