M68000 USER’S MANUAL ADDENDUM
MOTOROLA
AC ELECTRICAL SPECIFICATIONS — READ AND WRITE CYCLES (Continued)
Applies to 3.3V and 5V.
NOTES: 1.
For a loading capacitance of less than or equal to 50 pF, subtract 5 ns from the value given in the maximum columns.
2.
Actual value depends on clock period.
3.
If #47 is satised for both DTACK and BERR, #48 may be ignored. In the absence of DTACK, BERR is an asynchronous input
using the asynchronous input setup time (#47).
4.
For power-up, the MC68SEC000 must be held in the reset state for 100 ms to allow stabilization of on-chip circuitry. After the
system is powered up, #56 refers to the minimum pulse width required to reset the controller.
5.
If the asynchronous input setup time (#47) requirement is satised for DTACK, the DTACK asserted to data setup time (#31)
requirement can be ignored. The data must only satisfy the data-in to clock low setup time (#27) for the following clock cycle.
6.
When AS and R/W are equally loaded (
±20%), subtract 5 ns from the values given in these columns.
7.
The minimum value must be met to guarantee proper operation. If the maximum value is exceeded, BG may be reasserted.
