| G -LINK GLT6400L08 Ultra Low Power 512k x 8 CMOS SRAM Feb 2001(Rev. 1.1) Features : Low-power consumption. -active: 45mA at 85ns. -stand by : 20 A (CMOS input / output) 5 A (CMOS input / output, SL) Single +2.7 to 3.3V power supply. Description : The GLT6400L08 is a low power CMOS Static RAM organized as 524,288 x 8 bits. Easy memory expansion is provided by an active LOW CE1 an active LOW OE , and Tri-state I/O's. This device has an automatic power-down mode feature when deselected. Equal access and cycle time. Writing to the device is accomplished by taking 85 ns access time at 2.7V to 3.3V 70ns chip Enable 1 ( CE1 ) with Write Enable ( WE ) LOW. access time at 3V to 3.6V 1.0V data retention mode. TTL compatible, tri-state input/output. Automatic power-down when deselected. Industrial grade (-40C ~ 85C) available. Package available: sTSOP , SOP. Reading from the device is performed by taking Chip Enable 1 ( CE1 ) with Output Enable ( OE ) LOW while Write Enable ( WE ) and Chip Enable 2 (CE2) is HIGH. The I/O pins are placed in a high-impedance state when the device is deselected : the outputs are disabled during a write cycle. The GLT6400L08 comes with a 1V data retention feature and Lower Standby Power. The GLT6400L08 is available in a 32-pin sTSOP packages,and 32pin SOP package.
