Attention: Stresses above the max. values listed here may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability. Maximum ratings
are absolute ratings; exceeding only one of these values may cause irreversible damage to the integrated
circuit.

1) These values are guaranteed by design and are tested on a sample base only. V_DDQ = V_DD = 2.5 V ± 0.2 V, f = 100 MHz, T_A = 25 °C,
V_OUT(DC) = V_DDQ/2, V_OUT (Peak to Peak) 0.2 V. Unused pins are tied to ground.
2) DM inputs are grouped with I/O pins reflecting the fact that they are matched in loading to DQ and DQS to facilitate trace matching at the
board level.
