The POR remains active during VCC power-up, typically until 100 µs after 2.8V is reached. The POR follows VCC while active. Recommended Chemicals for Cleaning and Degreasing    Alcohols: methyl, isopropyl, isobutyl Aliphatics: hexane, heptanes Other: soap solution, naphtha Do not use partially halogenated hydrocarbons, such as 1,1,1 trichloroethane, or ketones, such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, Broadcom does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.
