VCC must be applied before or at the same time as Vpp and removed after or at the same time as Vpp. The device must not be inserted intoor removed from the board when Vpp or VCC is applied.2. Vpp can be connected to VCC directly (except in the program model. VCC supply current in this case would be ICC + Ipp. During programming,Vpp must be maintained at 21 V (±0.5 VI.UNITTEXASINSTRUMENTSPOST OFFICE BOX 225012 • DALLAS. TEXAS 752656-49
