Table 92. External Program Memory AC Characteristics (with the 3V MCU Module)
Note: 1. Conditions (in addition to those in Table 87, V
CC
= 3.0 to 3.6V): V
SS
= 0V; C
L
for Port 0, ALE and PSEN output is 100pF, for 5V
devices, and 50pF for 3V devices; C
L
for other outputs is 80pF, for 5V devices, and 50pF for 3V devices)
2. Interfacing the μPSD321X Devices to devices with float times up to 35ns is permissible. This limited bus contention does not cause
any damage to Port 0 drivers.
Table 93. External Clock Drive (with the 5V MCU Module)
Note: 1. Conditions (in addition to those in Table 86, V
CC
= 4.5 to 5.5V): V
SS
= 0V; C
L
for Port 0, ALE and PSEN output is 100pF; C
L
for
other outputs is 80pF
