Figure11. WRITE Swquence with One Clock Glitch
The ST93C06C is an enhanced version of the
ST93C06Aand offersthe followingextra features:
– EnhancedESD voltage
– Functionalsecurity filtering glitches on the
clock input(C).
Refer to Table 2 (Absolute Maximum Ratings) for
more about ESD limits. The following description
will detail the Clockpulsescounter (available only
on the ST93C06C).
In anormal environment,theST93C06is expected
to receivethe exactamountof data on the D input,
that is the exact amount of clock pulses on the C
input.
In a noisy environment, the amount of pulses re-
ceived (on the clock input C) may be greater than
theclockpulsesdeliveredbythe Master(Microcon-
troller) driving the ST93C06C. In such a case, a
part of the instruction is delayed by one bit (see
Figure11), and itmay inducean erroneouswriteof
data at a wrong address.
The ST93C46C has an on-board counter which
counts the clock pulses from the Start bit until the
falling edge of the Chip Select signal. For the
WRITE instructions, the number of clock pulses
incoming to the counter must be exactly 18 (with
the Organisation by 8) from the Start bit to the
fallingedge ofChipSelect signal(1 Startbit+2bits
of Op-code+ 7 bits of Address + 8 bits of Data =
18): if so, the ST93C06C executes the WRITE
instruction; if the number of clock pulses is not
equal to 18, the instruction will not be executed
(and data will not be corrupted).
In the same way, when the Organisationby 16 is
selected, the number of clock pulses incoming to
the countermust be exactly 25 (1 Startbit + 2 bits
of Op-code+ 6 bits of Address + 16 bits of Data =
25) from the Start bit to the falling edge of Chip
Select signal: if so, the ST93C06C executes the
WRITE instruction;if thenumber of clockpulses is
not equalto 25, theinstruction will not be executed
(and data will not be corrupted). The clock pulse
counter is active only on ERASE and WRITE in-
structions(WRITE, ERASE, ERAL, WRALL).
