NOTES:
1.
All voltages are referenced to ground.
2.
Logic 1 voltages are specified at V
CC
=3.3V, V
OH
=V
CC
for capacitive loads. Excludes
RST
pin.
3.
Logic 0 voltages are specified at V
CC
=3.3V, V
OL
=GND for capacitive loads.
4.
I
CCA
is specified with outputs open, CS set to a logic 1, SCLK=500 kHz, oscillator enabled, and D/A
converter enabled.
5.
I
ADC
is specified with CS, V
CCO
open and I/O, SCLK at logic zero. A/D converter is enabled.
6.
I
CCS
is specified with CS, V
CCO
open and I/O, SCLK at logic zero. A/D converter is disabled.
7.
CS has a 40 k
pull-down resistor to ground.
8.
Measured at V
IH
=2.0V or V
IL
=0.8V and 10 ns maximum rise and fall time.
9.
Measured at V
OH
=2.4V or V
OL
=0.4V.
10.
Load capacitance = 50 pF.
11.
I
CCO
=100 mA, V
CC
> V
CCTP
.
12.
V
CCO
switchover from V
CC
to V
BAT
occurs when V
CC
drops below the lower of V
CCSW
and V
BAT
.
13.
Current from V
CC
input pin to V
CCO
output pin.
14.
Current from V
BAT
input pin to V
CCO
output pin.
15.
Time base is generated by very accurate crystal oscillator. Accuracy of this time period is based on
the crystal that is used. A typical crystal with a specified load capacitance of 6 pF will provide an
accuracy within ±100 ppm over the 0°C to 70°C temperature range.
16.
If the
EOSC
bit in the Control Register is set to a logic 1, t
RPU
is equal to 250 ms plus the start-up
time of the crystal oscillator.
