Table A-4 lists the delays in gross memory access time.
The measurements are taken at the 50% points under the following conditions.
• T = -40°C to 85°C, V = V
• Internal clock to nonloaded CLK pin delay ≤ 1 ns @ 85°C/3.0 V
The clock to address output delays are similar, and apply to the following delays.
• T

The data setup time delays are similar for both T
When the spectrum spreader and the clock doubler are both enabled, every other clock
cycle is shortened (sometimes lengthened) by a maximum amount given in Table A-4
above. The shortening takes place by shortening the high part of the clock. If the doubler
is not enabled, then every clock is shortened during the low part of the clock period. The
maximum shortening for a pair of clocks combined is shown in Table A-4.
Technical Note TN227, Interfacing External I/O with Rabbit 2000/3000 Designs, con-
tains suggestions for interfacing I/O devices to the Rabbit 3000 microprocessors.
