UPD42S16800L

The UPD42S16800L is designed as 2097152 wirds by 8 bits dynamic CMOS RAM with refresh cycle of 4096 cycles/ 128ms.

UPD42S16800L has five features. (1)2097152 words by 8 bits organization. (2)Fast page mode. (3)SIngle 3.3V +/-0.3V power supply. (4)It can execute CAS before RAS self refresh. (5)Fast access and cycle time. That are all the main features.

Some absolute maximum ratings of UPD42S16800L have been concluded into several points as follow. (1)Its voltage on any pin relative to GND would be from -0.5V to +4.6V. (2)Its supply voltage would be from -0.5V to +4.6V. (3)Its output current would be 20mA. (4)Its power dissipation would be 1W. (5)Its operating temperature range would be from 0°C to +70°C. (6)Its storage temperature range would be from -55°C to +125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some DC characteristics of UPD42S16800L are concluded as follow. (1)Its operating current would be max 80mA at tRAC=60ns and max 70mA at tRAC=70ns and would be 60mA at tRAC=80ns. (2)Its standby current would be max 0.5mA at Vir(min)<=RAS, CAS and would be max 0.15mA at Vcc-0.2V <=RAS, CAS. (3)Its RAS only refresh current would be max 80mA at tRAC=60ns and max 70mA at tRAC=70ns and would be 60mA at tRAC=80ns. (4)Its operating current fast page mode would be max 70mA at tRAC=60ns and max 60mA at tRAC=70ns and would be 50mA at tRAC=80ns. (5)Its CAS before RAS would be max 80mA at tRAC=60ns and max 70mA at tRAC=70ns and would be 60mA at tRAC=80ns. (6)Its CAS before RAS long refresh current would be max 220uA. (7)Its self refresh current would be max 150uA. (8)Its input leakage current would be min -5uA and max +5uA. (9)Its output leakage current would be min -5uA and max +5uA. (10)Its high level output voltage would be min 2.4V. (11)Its low level output voltage would be max 0.4V. And so on.
