Rev. 1.1
512K X 16 BITS LOW POWER PSEUDO SRAM
GENERAL DESCRIPTION
UT65L168(E)/UT65L168(I)
The UT65L168 is a 8,388,608-bit CMOS random access memory organized as 524,288 words by 16 bits. It is fabricated using PSEUDO SRAM techniques, yields high-density and low power consumption device. The UT65L168 is design for upper and low byte access by data byte control ( UB LB ).It has low power modes by using control pin ZZ .
FEATURES
Fast access time : 60/70ns (max.) Low operating power Operating current : 20mA (typ) Standby current : 50uA (typ) Power supply voltage : 2.5V~3.3V Operating temperature : Extended(E) : -20 ~ 80 Industrial(I) : -40 ~ 85 Low power modes Deep power Down : Isb < 10uA Three state output and TTL compatible Separated I/O power (Vccq) & Core Power (Vcc) Page mode operation by 8 words Data byte control : LB (I/O1~I/O8) UB (I/O9~I/O16) Package : 48-pin 6.0mm × 8.0mm TFBGA 48-pin 12mmX20mm TSOP-I
