Can anyone help with that please? In the internet I found specs defining it as 8GB chip No further options offered in software. PC3K Flash shows right result. See this topic for details.

The device is offered in 3. Its NAND cell provides the most cost-effective solution for the solid state mass storage market. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. The device contains blocks, composed by 64 pages consisting in two NAND structures of 32 series connected Flash cells.
A program operation allows to write the byte page in typical us and an erase operation can be performed in typical 2ms on a K-byte X8 device block. Data in the page mode can be read out at 30ns cycle time per byte. This interface allows a reduced pin count and easy migration towards different densities, without any rearrangement of footprint.
The modifying can be locked using the WP input pin. The output pin RB open drain buffer signals the status of the device during each operation. In a system with multiple memories the RB pins can be connected all together to provide a global status signal. This option allows the direct download of the code from the NAND Flash memory device by a microcontroller, since the CE transitions do not stop the read operation. The copy back function allows the optimization of defective blocks management: when a page program operation fails the data can be directly programmed in another page inside the same array section without the time consuming serial data insertion phase.
The cache program feature allows the data insertion in the cache register while the data register is copied into the flash array. This pipelined program operation improves the program throughput when long files are written inside the memory. A cache read feature is also implemented. This feature allows to dramatically improve the read throughput when consecutive pages have to be streamed out.

This number indicates quantity of items that could be produced from components in stock. Reasonable quantity of this product can be available within 3 working days. In case of missed samples, we always asking the semiconductor manufacturer for samples, but if samples are not available - also in the package you're asking for the support - the solution from us will be delayed. The real chips are also necessary to have in the case of reproducing issues from the created support. Therefore we can return your samples only if we get chips from semiconductor manufacturer.
