  • News - Dear ON Semiconductor | about 4 years ago

    When Motorola spun off their semiconductor business, Freescale got the LSI circuits while ON Semiconductor got the discrete devices and MSI circuits so this is not a processor. The large metal chunks (the white areas) on the chip are probably capacitors so this may be at least a semi-analog circuit, maybe a power management circuit or something similar.
    It is interesting there are 32 pins on the package but 33 bond pads on the chip. The extra pad is the one in the center on the right side and looks like the VSS pin since it is connected to the metal ring around the periphery of the chip to which all the ESD protections are connected. Have yo figured out where this pin goes?

No public wish lists :(
