Notes:
2. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC (typ) and TA = 25°C.
3. Ball H1, G2, H6 are the address expansion pins for the 8-Mb, 16-Mb, and 32-Mb densities, respectively.
4. NC âno connectâânot connected internally to the die.
5. DNU (Do Not Use) pins have to be left floating or tied to VSS to ensure proper application.
