Description of Change
** 2975554 RAME 07/09/2010 New Datasheet
*A 3056347 ADMU 10/28/2010 Updated “Selection Guide” on page 1:
For speed bin -25: Typical Operating current(mA) changed from 180 to 170, Typical
standby current for ISB1 (mA) changed from 45 to 40
For speed bin -55: Typical Operating current(mA) changed from 180 to 150, Typical
standby current for ISB1 (mA) changed from 45 to 20
Updated “Electrical Characteristics Over the Operating Range” on page 9:
The values for the speed bins -25 and -55 have been put into separate columns. The values
for Commercial parts have been modified for the following parameters: (no degradation of
spec)
Operating Current ICC: “180(typ) / 275(max)” changed to “170(typ) / 250(max) for speed
bin -25” and “150(typ) / 230(max) for speed bin -55”
Standby Current ISB1 (both ports TTL levels): “45(typ) / 65(max)” changed to
“40(typ) / 60(max) for speed bin -25”, and “20(typ) / 50(max) for speed bin -55”
Standby Current ISB2 (one port TTL level) : “110(typ) / 160(max)” changed to
“100(typ) / 150(max) for speed bin -25”, and “75(typ) / 135(max) for speed bin -55”
Standby Current ISB4 (both ports CMOS Levels) : “100(typ) / 140(max)” changed to
“90(typ) / 130(max) for speed bin -25”, and “70(typ) / 120(max) for speed bin -55”
Updated “Ordering Information (4K x 18 Dual-Port SRAM)” on page 19:
Removed part CY7C0241E - 55AXI from ordering information.
