Notes:
*1. RST pin is a Schmitt trigger input.
*2. P0, ALE and /PSEN are tested in the external access mode.
*3. XTAL1 is a CMOS input.
*4. Pins of P1, P2, P3, P4 can source a transition current when they are being externally driven from 1 to 0.
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.

Notes:
1. The clock may be stopped indefinitely in either state.
2. The T

specification is used as a reference in other specifications.
3. There are no duty cycle requirements on the XTAL1 input.
