    Difference between CY7C1339G and CY7C1339S

    ShUc_4173626

      Hi,

      Would you please let me know what is difference between CY7C1339G-133AXC and CY7C1339S-133AXC ?

      Can I use CY7C1339"S" instead of CY7C1339"G" ?   Is there anything I need to take care of ?  

       

      Thanks,

          Hi,

          You can use CY7C1339S to replace CY7C1339G.

          I only check the functionality and the DC/AC electrical characteristics.

          These two devices have the same functionality and no other major points to be cared.

          The DC/AC electrical characteristics are shown in following tables.
