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 (not
available on AT devices)
• Auto refresh
64ms, 4,096-cycle refresh (15.6µs/row)
(commercial and industrial)
16ms, 4,096-cycle refresh (3.9µs/row)
(automotive)
• LVTTL-compatible inputs and outputs
• Low voltage power supply
• Partial-array self refresh (PASR) power-saving mode
