DRAFT(Thursday 20 June 2002, 13:15).
Table 116. External Program Memory AC Characteristics (with the 3V MCU Module)
Note: 1. Conditions (in addition to those in Table 109, V
CC
=3.0 to 3.6 V): V
SS
= 0 V; C
L
for Port 0, ALE and PSEN output is 100 pF, for 5V
devices, and 50 pF for 3V devices; C
L
for other outputs is 80 pF, for 5V devices, and 50 pF for 3V devices)
2. Interfacing the
μ
PSD3200 Family to devices with float times up to 35 ns is permissible. This limited bus contention does not cause
any damage to Port 0 drivers.
