CY62148BN MoBL®  
4-Mbit (512K x 8) Static RAM  
Functional Description  
Features  
• High Speed  
The CY62148BN is a high-performance CMOS static RAM  
organized 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 an automatic power-down feature that reduces power  
consumption by more than 99% when deselected.  
— 70 ns  
• 4.5V–5.5V operation  
• Low active power  
— Typical active current: 2.5 mA @ f = 1 MHz  
— Typical active current:12.5 mA @ f = fmax(70 ns)  
Low standby current  
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  
specified on the address pins (A0 through A18).  
• 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  
Enable (CE) and Output Enable (OE) LOW while forcing Write  
Enable (WE) HIGH for read. Under these conditions, the  
contents of the memory location specified by the address pins  
will appear on the I/O pins.  
• Available in standard lead-free and non-lead-free  
32-lead (450-mil) SOIC, 32-lead TSOP II and 32-lead  
Reverse TSOP II packages  
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).
