Targeted AC Specifications
All the non-analog input, output, and I/O pins on the processor can be divided into one of two
categories:
1. High Strength Input, Output, and I/O pins:
• nCS[5:1] (GP 33, 80, 79, 78, 15 respectively), nCS[0]
• MD[31:0], MA[25:0]
• DQM[3:0]
• nOE, nWE, nSDRAS, nSDCAS, nSDCS[3:0]
• SDCLK[2:0], SDCKE[1:0]
• RDnWR, RDY (GP[18])
• nPWE, nPOE pins (GP[49:48])
• MMCLK (GP[53]), MMCMD, MMDAT
• TDO
• nACRESET
2. Low Strength Input, Output, and I/O pins - all remaining non-supply pins
A pin’s AC characteristics include input and output capacitance, which determine loading for
external drivers or other load analysis. The AC characteristics also include a de-rating factor, which
indicates how much faster or slower the AC timings get with different loads. Table 12, “Standard
Input, Output, and I/O Pin AC Operating Conditions” shows the AC operating conditions for the
high- and low-strength input, output, and I/O pins. All AC specification values are valid for the
entire temperature range of the device.
