PROGRAMMING THE EPROM
The part must be running with a 4 MHz to 6 MHz
oscillator The address of an EPROM location to be
programmed is applied to address lines while the
code byte to be programmed in that location is ap-
plied to data lines Control and program signals must
be held at the levels indicated in Table 4 Normally
EA VPP is held at logic high until just before ALE
PROG is to be pulsed The EA VPP is raised to VPP
ALEPROG is pulsed low and then EA VPP is re-
turned to a high (also refer to timing diagrams)
NOTES
 Exceeding the VPP maximum for any amount of
time could damage the device permanently The
VPP source must be well regulated and free of
glitches
