USER’S MANUAL
Use of an external circuit to condition VPP is recommended.
simple circuit that maintains required voltages and filters transients. VPP is pulled up
to VDDL via Schottky diode D2, protecting VDDL from excessive reverse current. D2
also protects the FLASH from damage should the programming voltage go to zero.
Programming power supply voltage must be adjusted to compensate for the forward-
