CY62148B MoBL™  
512K x 8 Static RAM  
an automatic power-down feature that reduces power con-  
sumption by more than 99% when deselected.  
Features  
4.5V5.5V operation  
Low active power  
Writing to the device is accomplished by taking Chip Enable  
(CE) and Write Enable (WE) inputs LOW. Data on the eight I/O  
pins (I/O0 through I/O7) is then written into the location speci-  
fied on the address pins (A0 through A18).  
Typical active current: 2.5 mA @ f = 1 MHz  
Typical active current: 12.5 mA @ f = fmax  
Low standby current  
Automatic power-down when deselected  
TTL-compatible inputs and outputs  
Easy memory expansion with CE and OE features  
CMOS for optimum speed/power  
Reading from the device is accomplished by taking Chip En-  
able (CE) and Output Enable (OE) LOW while forcing Write  
Enable (WE) HIGH for read. Under these conditions, the con-  
tents of the memory location specified by the address pins will  
appear on the I/O pins.  
The eight input/output pins (I/O0 through I/O7) are placed in a  
high-impedance state when the device is deselected (CE  
HIGH), the outputs are disabled (OE HIGH), or during a write  
operation (CE LOW, and WE LOW).  
Functional Description  
The CY62148B is a high-performance CMOS static RAM or-  
ganized as 512K words by 8 bits. Easy memory expansion is  
provided by an active LOW Chip Enable (CE), an active LOW  
Output Enable (OE), and three-state drivers. This device has  
The CY62148B is available in a standard 32-pin 450-mil-wide  
body width SOIC, 32-pin TSOP II, and 32-pin Reverse TSOP  
II packages.
