CY7C1046D  
4-Mbit (1 M × 4) Static RAM  
4-Mbit (1  
M × 4) Static RAM  
Features  
Functional Description  
Pin- and function-compatible with CY7C1046B  
The CY7C1046D[1] is a high-performance CMOS static RAM  
organized as 1M words by 4 bits. Easy memory expansion is  
provided by an active LOW Chip Enable (CE), an active LOW  
Output Enable (OE), and tri-state drivers. Writing to the device  
is accomplished by taking Chip Enable (CE) and Write Enable  
(WE) inputs LOW. Data on the four I/O pins (I/O0 through I/O3)  
is then written into the location specified on the address pins  
(A0 through A19).  
High speed  
tAA = 10 ns  
CMOS for optimum speed/power  
Low active power  
ICC = 90 mA @ 10 ns  
Reading from the device is accomplished by taking Chip  
Enable (CE) and Output Enable (OE) LOW while forcing Write  
Enable (WE) HIGH. Under these conditions, the contents of  
the memory location specified by the address pins will appear  
on the I/O pins.  
Low CMOS Standby Power  
ISB2 = 10 mA  
Data Retention at 2.0 V  
Automatic power-down when deselected  
TTL-compatible inputs and outputs  
The four input/output pins (I/O0 through I/O3) 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).  
Easy memory expansion with CE and OE features  
Available in lead-free 400-mil-wide 32-pin SOJ package  
The CY7C1046D is available in a standard 400-mil-wide  
32-pin SOJ package with center power and ground  
(revolutionary) pinout.
