NOTES FOR DC ELECTRICAL CHARACTERISTICS:
All parameters apply to both commercial and industrial temperature operation unless otherwise noted.
1. All voltages are referenced to ground.
2. Active current is measured with a 33 MHz clock source driving XTAL1, V
CC
=RST=5.5V, all other pins discon-
nected.
3. Idle mode current is measured with a 33 MHz clock source driving XTAL1, V
CC
=5.5V, RST at ground, all other
pins disconnected.
4. Stop mode current measured with XTAL1 and RST grounded, V
CC
=5.5V, all other pins disconnected. This value
is not guaranteed. Users that are sensitive to this specification should contact Dallas Semiconductor for more
information.
5. When addressing external memory.
6. RST=V
CC
. This condition mimics operation of pins in I/O mode. Port 0 is tristated in reset and when at a logic
high state during I/O mode.
7. During a 0 to 1 transition, a one–shot drives the ports hard for two clock cycles. This measurement reflects port
in transition mode.
8. Ports 1, 2, and 3 source transition current when being pulled down externally. It reaches its maximum at approxi-
mately 2V.
9. 0.45<V
IN
<V
CC
. Not a high impedance input. This port is a weak address holding latch in Bus Mode. Peak current
occurs near the input transition point of the latch, approximately 2V.
10.0.45<V
IN
<V
CC
. RST=V
CC
. This condition mimics operation of pins in I/O mode.
11. V

=0V, V
BAT
=3.3V. 32.768 KHz crystal with 12.5 pF load capacitance between RTCX1 and RTCX2 pins. RTCE
