The automotive temperature (AT) option, if offered, has two simultaneous require-
ments: ambient temperature surrounding the device cannot be less than –40°C or
greater than +105°C, and the case temperature cannot be less than –40°C or greater
than +105°C. JEDEC specifications require the refresh rate to double when T
+85°C; this also requires use of the high-temperature self refresh option. Additionally,
ODT resistance and the input/output impedance must be derated when T
+85°C.

term is to be interpreted as any and all DQ collectively, unless specifically stated oth-
erwise. Additionally, the x16 is divided into 2 bytes: the lower byte and the upper byte.
For the lower byte (DQ0–DQ7), DM refers to LDM and DQS refers to LDQS. For the
upper byte (DQ8–DQ15), DM refers to UDM and DQS refers to UDQS.
