10 ns access time — bus timing margin
The 10 ns access time and write cycle time allow back-to-back reads and writes at the same rate.
256K x 16 organization — word-wide bus fit
The 16-bit-wide data bus matches the native word width of 16-bit MCUs. The 4Mbit density (256K x 16) suits small-to-medium packet buffers or parameter storage.
Package and lifecycle reality
The part ships in a 44-pin SOJ package with a 0.400-inch body width. The lifecycle status is Active, meaning Infineon continues to manufacture this part.
