I
Address lines
P2.0-7 are used as multiplexed address input lines
A0-A7 and A8-A15. A8-A15 must be latched with PALE.
PSEN
47
I
Program store enable
This input must be at static “0” level during the whole
programming mode.
PROG
48
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
49
I
External Access / Programming voltage
This pin must be at 11.5 V (
VPP) voltage level during
programming of an OTP memory byte or lock bit. During
an OTP memory read operation this pin must be at high
level (
VIH). This pin is also used for basic programming
mode selection. At basic programming mode selection
a low level must be applied to EA/
VPP.
D0 - 7
52 - 58
I/O
Data lines 0-7
During programming mode, data bytes are read or
written from or to the C515C-8E via the bidirectional
D0-7 which are located at port 0.
VSS

Circuit ground potential
must be applied to these pins in programming mode.
VDD
14, 32, 33,

Not Connected
These pins should not be connected in programming
mode.
