5. When addressing external memory.
6. RST= V
CC
. This condition mimics operation of pins in 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 approximately 2V.
9. V
IN
between ground and V
CC
- 0.3V. Not a high impedance input. This port is a weak address latch
because Port 0 is dedicated as an address bus on the DS80C323. Peak current occurs near the input
transition point of the latch, approximately 2V.
10. Over the industrial temperature range, this specification has a maximum value of 200 μA.
11. This is the current from an external circuit to hold a logic low level on an I/O pin while the
corresponding port latch bit is set to 1. This is only the current required to
hold
the low level;
transitions from 1 to 0 on an I/O pin will also have to overcome the transition current.
12. Device operating range is 2.7V to 5.5V, however device is tested to 2.5V to ensure proper operation
at minimum V
RST
