NOTES:
1. All voltages are referenced to ground.
2. Logic 1 voltages are specified at V
CC
= 3.0V, V
OH
= V
CC
for capacitive loads. Excludes
RST
pin
3. Logic 0 voltages are specified at V
CC
= 3.0V, V
OL
= GND for capacitive loads.
4. I
CCA
is specified with outputs open, CS set to a logic 1, SCLK = 500kHz, oscillator enabled, and
D/A converter enabled.
5. I
ADC
is specified with CS, V
CCO
open and I/O, SCLK at logic 0. ADC is enabled.
6. I
CCS
is specified with CS, V
CCO
open and I/O, SCLK at logic 0. ADC is disabled.
7. CS has a 40k pulldown resistor to ground.
8. Measured at V
IH
= 2.0V or V
IL
= 0.8V and 10ns maximum rise and fall time.
9. Measured at V
OH
= 2.4V or V
OL
= 0.4V.
10. Load capacitance = 25pF.
11. I
CCO
= 100mA, 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 6pF will provide an
accuracy within ±100ppm 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 250ms plus the startup
time of the crystal oscillator.
