PROM Write Mode Timing (Byte Program Mode)
Cautions 1. V
DDP
must be applied before V
PP
, and must be cut after V
PP
.
2. V
PP
including overshoot must not exceed +13.5 V.
3. Plugging in or out the board with the V
PP
pin supplied with 12.5 V may adversely affect its
reliability.
PROM Read Mode Timing
Notes 1.
For reading within t
ACC
, the delay of the OE input from falling edge of CE must be within t
ACC
-t
OE
.
2.
t
DF
is the time measured from when either OE or CE reaches V
IH
, whichever is faster.
