Figure 3.2 Eprom Programming Timing
The operations above are managed by using the
internal 4-bit EPROM Control Register. The
reading phase is executed with VPP= 5V±5%, while
the
verify/Margin
Mode
phase
needs
VPP=
12V
±5%. The Blank Check must be a reading
operation with VPP= 5V±5%.
Table 3.2 illustrates EPROM Control Register
codes used to identify the operation running.
3.1 EPROM Programming Phase Procedure
The Programming mode is selected by applying
12V
±5% voltage or 5V±5% voltage to the VPP pin
and setting the control signal as following:
RESET =Vss
TEST =Vss
If the VPP voltage is 5V±5% only reading may be
performed.
RST_ADD, INC_ADD, RST_CONF, INC_CONF
and PHASE are the control signals used during the
Programming Mode.
PHASE, RST_CONF and RST_ADD signals are
active on level, the others are active on rising
edge.
