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/VPP
29
External Access / Programming voltage
This pin must be at 11.5V (VPP) voltage level during
programming of an OTP memory byte or lock bit. During an
OTP memory read operation this pin must be at VIH 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/VPP.
D7-0
30-37
I/O
Data lines 0-7
During programming mode, data bytes are transferred via the
bidirectional port 0 data lines.
