PRELIMINARY  
CY7C199B  
32K x 8 Static RAM  
is provided by an active LOW Chip Enable (CE) and active  
LOW Output Enable (OE) and three-state drivers. This device  
has an automatic power-down feature, reducing the power  
consumption by 81% when deselected. The CY7C199B is in  
the standard 300-mil-wide DIP, SOJ, and LCC packages.  
Features  
• High speed  
— 10 ns  
• Fast t  
DOE  
An active LOW Write Enable signal (WE) controls the writ-  
ing/reading operation of the memory. When CE and WE inputs  
• CMOS for optimum speed/power  
• Low active power  
are both LOW, data on the eight data input/output pins (I/O  
0
— 495 mW (max, 10 ns “L” version)  
• Low standby power  
through I/O ) is written into the memory location addressed by  
7
the address present on the address pins (A through A ).

Reading the device is accomplished by selecting the device  
and enabling the outputs, CE and OE active LOW, while WE  
remains inactive or HIGH. Under these conditions, the con-  
tents of the location addressed by the information on address  
pins are present on the eight data input/output pins.  
— 0.275 mW (max, “L” version)  
• 2V data retention (“L” version only)  
• Easy memory expansion with CE and OE features  
• TTL-compatible inputs and outputs  
• Automatic power-down when deselected  
The input/output pins remain in a high-impedance state unless  
the chip is selected, outputs are enabled, and Write Enable  
(WE) is HIGH. A die coat is used to improve alpha immunity.  
Functional Description  
The CY7C199B is a high-performance CMOS static RAM or-  
ganized as 32,768 words by 8 bits. Easy memory expansion
