DS2250(T) TYPICAL I
CC
VS. FREQUENCY
FREQUENCY OF OPERATION (MHz)
(V
CC
=+5V, t
A
=25
°
C)
Normal operation is measured using:
1)
External crystals on XTAL1 and 2
2)
All port pins disconnected
3)
RST=0 volts and EA=V
CC
4)
Part performing endless loop writing to internal memory
Idle mode operation is measured using:
1)
External clock source at XTAL1; XTAL2 floating
2)
All port pins disconnected
3)
RST=0 volts and EA=V
CC
4)
Part set in IDLE mode by software
NOTES:
1.
All voltages are referenced to ground.
2. Maximum operating I
CC
is measured with all output pins disconnected; XTAL1 driven with t
CLKR
,
t
CLKF
= 10 ns, V
IL
= 0.5V; XTAL2 disconnected;
EA
= RST = PORT0 = V
CC
.
3. Idle mode I
CC
is measured with all output pins disconnected; XTAL1 driven at 8 MHz with t
CLKR
,
t
CLKF
= 10 ns, V
IL
= 0.5V; XTAL2 disconnected;
EA
= PORT0 = V
CC
, RST = V
SS
.
4. Stop mode I
CC
is measured with all output pins disconnected;
EA
= PORT0 = V
CC
; XTAL2 not
connected; RST = V
SS
.
5. Crystal start-up time is the time required to get the mass of the crystal into vibrational motion from
the time that power is first applied to the circuit until the first clock pulse is produced by the on-chip
oscillator. The user should check with the crystal vendor for the worst case spec on this time.
