Note 1:
All parameters apply to both commercial and industrial temperature operation, unless otherwise noted.
Note 2:
All voltages are referenced to ground.
Note 3:
Active current measured with 33MHz clock source on XTAL1, VCC = RST = 5.5V, other pins disconnected.
Note 4:
Idle mode current measured with 33MHz clock source on XTAL1, VCC = 5.5V, RST at ground, other pins
disconnected.
Note 5:
Stop mode current measured with XTAL1 and RST grounded, VCC = 5.5V, all other pins disconnected.
Note 6:
When addressing external memory. This specification only applies to the first clock cycle following the transition.
Note 7:
RST = VCC. This condition mimics operation of pins in I/O mode. Port 0 is tri-stated in reset and when at a logic high
state during I/O mode.
Note 8:
During a 0-to-1 transition, a one-shot drives the ports hard for two clock cycles. This measurement reflects port in
transition mode.
Note 9:
Ports 1, 2, and 3 source transition current when being pulled down externally. It reaches its maximum at approximately
2V.
Note 10:
0.45 < VIN < VCC. 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.
Note 11:
0.45 < VIN < VCC. RST = VCC. This condition mimics operation of pins in I/O mode.
Note 12:
This is the current required 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.
