Module height: 17.9mm (0.705in)

Options Marking

• Parity P

• Operating temperature

– Commercial (0°C ≤ T

≤ +70°C) D

– Industrial (–40°C ≤ T

≤ +85°C)

• Package

– 240-pin DIMM (halogen-free) Z

• Frequency/CL

– 2.5ns @ CL = 5 (DDR2-800) -80E

– 2.5ns @ CL = 6 (DDR2-800) -800

– 3.0ns @ CL = 5 (DDR2-667) -667

Notes:

1. Contact Micron for industrial temperature

module offerings.

2. CL = CAS (READ) latency; registered mode

will add one clock cycle to CL.
