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.

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.
