Features
• Temperature compensated self refresh (TCSR)
• Fully synchronous; all signals registered on positive
edge of system clock
• Internal pipelined operation; column address can
be changed every clock cycle
• Internal banks for hiding row access/precharge
• Programmable burst lengths: 1, 2, 4, 8, or full page
• Auto Precharge, includes concurrent auto
precharge, and auto refresh modes
• Self refresh mode; standard and low power
• 64ms, 4,096-cycle refresh
• LVTTL-compatible inputs and outputs
• Low voltage power supply
• Partial array self refresh power-saving mode
• Deep power-down mode
• Programmable output drive strength
• Operating temperature ranges:
Extended (-25°C to +85°C)
Industrial (-40°C to +85°C)

FBGA Part Number System
Due to space limitations, FBGA-packaged compo-
nents have an abbreviated part marking that is differ-
ent from the part number. For a quick conversion of an
FBGA code, see the FBGA Part Marking Decoder on the
Micron web site,
