Circuit ground potential
Must be applied in programming mode.
Power supply terminal
Must be applied in programming mode.
Address lines
Multiplexed address input lines A0-A7 and A8-A14. A8-A14
must be latched with PALE.
Program Store ENable
This input must be at static “0” level during the whole
programming mode.
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.
Programming voltage
This pin must be at 11.5 V (
programming of an OTP memory byte or lock-bit. During an
OTP memory read operation, this pin must be at
This pin is also used for basic programming mode selection. At
basic programming mode selection a low level must be applied
to EA/
Data lines 0-7
During programming mode, data bytes are transferred via the
bidirectional D7-D0 lines that are located at port 0 pins.
Not Connected
These pins should not be connected in programming mode.
