P2.0-7
18-25
I
Address lines
P2.0-7 are used as multiplexed address input lines A0-A7 and
A8-A14. A8-A14 must be latched with PALE.
PSEN
26
I
Program store enable
This input must be at static “0“ level during the whole
programming mode.
PROG
27
I
Programming mode write strobe
This input is used in programming mode as a write strobe for
OTP memory program, and lock bit write operations During
basic programming mode selection a low level must be applied
to PROG.
EA/V
PP
29
External Access / Programming voltage
This pin must be at 11.5V (V
PP
) voltage level during
programming of an OTP memory byte or lock bit. During an
OTP memory read operation this pin must be at V
IH
high level.
This pin is also used for basic programming mode selection. At
basic programming mode selection a low level must be applied
to EA/V
PP
.
Data lines 0-7
During programming mode, data bytes are transferred via the
bidirectional port 0 data lines.
