Electrical, Mechanical, and Thermal Specification
Intel PXA270 Processor
AC Timing Specifications
During writes, data pins are actively driven by the processor and are not three-stated, regardless of
the states of the individual DQM signals. For SRAM writes, the DQM signals are used as byte
enables.
Note: Table 6-19 lists programmable register items. See the “Memory Controller”chapter in the Intel
PXA27x Processor Family Developer’s Manual for register configurations for more information on
these items.

NOTES:
1. Numbers shown as integer multiples of the CLK_MEM period are ideal. Actual numbers vary with pin-to-pin differences in
loading and transition direction (rise or fall).
2. On the first data beat of burst transfer, the tsramASW is 3 CLK_MEM periods. On subsequent data beats, the tsramASW is 1
CLK_MEM period.
