The values from the table above are derived using 55 ns (25.8 MHz version) and 90 ns
(18.4 MHz version) memory access times. External capacitive loading can be improved
by 10 pF for commercial temperature ranges, but do not exceed 100 pF. See the AC timing
specifications in the Rabbit 2000 Microprocessor User’s Manual for more information.
Figure A-4 shows a typical timing diagram for the Rabbit 2000 microprocessor memory
read and write cycles.
Figure A-4. Memory Read and Write Cycles
Tadr is the time required for the address output to reach 0.8 V. This time depends on the
bus loading. A0 has a stronger driver and can handle larger capacitive loads than the other
address lines. Tsetup is the data setup time relative to the clock. Tsetup is specified from
30%/70% of the VDD voltage level. Add 1.5 ns to Tadr for each 10 pF of additional bus
loading above 70 pF.
