Probably you should use to PIC16C63JW power supply at range 4.0 - 6.0 v
JW device don't like power below 4.0v, IMHO (by practical experiments
with 63/65JW)

WBR Dmitry.
P.S. When I was start my experiments with JW devices PIC16C63JW/04 was
stable running
at power supply 4.0v . After ~200 cycles of erasing this device starting
to function
only at power supply 4.5v or higher ;(
