Table 2. KIO Registers
The DC Characteristics and Capacitance sections below apply to the following standard
test conditions, unless otherwise noted. All voltages are referenced to GND (0V). Posi-
tive current flows into the referenced pin.
Available operating temperature ranges are:
•
•
Voltage Supply Range: +5.0V ± 10%
All AC parameters assume a load capacitance of 100 pF. Add 10 ns delay for each 50 pF
increase in load up to a maximum of 200 pF for the data bus and 100 pF for the address
and control lines. AC timing measurements are referenced to 1.5 volts (except for
CLOCK, which is referenced to the 10% and 90% points.
