Notes:
*1. Pins P1, P2 and P3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches
its maximum value when V
IN
is approximately 2V.
*2. RST pin has an internal pull-down resistor.
*3. P0, ALE, PSEN are in the external access memory mode.
*4. XTAL1 is a CMOS input and RST is a Schmitt trigger input.
AC CHARACTERISTICS
The AC specifications are a function of the particular process used to manufacture the part, the
ratings of the I/O buffers, the capacitive load, and the internal routing capacitance. Most of the
specifications can be expressed in terms of multiple input clock periods (T
CP
), and actual parts will
usually experience less than a
±
20 nS variation. The numbers below represent the performance
expected from a 0.6micron CMOS process when using 2 and 4 mA output buffers.
