This highly reliable process coupled with innovative circuit design techniques, yields higher performance and low power consumption devices. When CE1 is HIGH or CE2 is LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced by using CMOS input levels. Easy memory expansion is provided by using two Chip Enable inputs, CE1 and CE2. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IC62LV2568L and IC62LV2568LL are available in 32-pin 8*20mm TSOP-1, 8*13.4mm TSOP-1 and 48-pin 6*8mm T.BGA. .UNCTIONAL BLOCK DIAGRAM A0-A17 DECODER 2048 x 128 x 8 MEMORY ARRAY VCC GND I/O DATA CIRCUIT I/O0-I/O7 COLUMN I/O CE1 CE2 OE WE CONTROL CIRCUIT ICSI reserves the rig...
