FUNCTIONAL DESCRIPTION  
The AS7C256 is a high performance CMOS 262,144-bit A write cycle is accomplished by asserting chip enable (CE)  
Static Random Access Memory (SRAM) organized as  
32,768 words × 8 bits. It is designed for memory applica-  
tions where fast data access, low power, and simple interfac-  
ing are desired.  
and write enable (WE) LOW. Data on the input pins  
I/O0-I/O7 is written on the rising edge of WE (write cycle 1)  
or CE (write cycle 2). To avoid bus contention, external  
devices should drive I/O pins only after outputs have been  
disabled with output enable (OE) or write enable (WE).  
Equal address access and cycle times (t , t , t ) of  
AA RC WC  
10/12/15/20/25/35 ns with output enable access times (t  
)
OE  
A read cycle is accomplished by asserting chip enable (CE)  
and output enable (OE) LOW, with write enable (WE)  
HIGH. The chip drives I/O pins with the data word refer-  
enced by the input address. When chip enable or output  
enable is HIGH, or write enable is LOW, output drivers stay  
in high-impedance mode.  
of 3/3/4/5/6/8 ns are ideal for high performance applica-  
tions. A chip enable (CE) input permits easy memory  
expansion with multiple-bank memory organizations.  
When CE is HIGH the device enters standby mode. The  
standard AS7C256 is guaranteed not to exceed 11 mW  
power consumption in standby mode; the L version is guar-  
anteed not to exceed 2.75 mW, and typically requires only  
500 µW. The L version also offers 2.0V data retention, with  
maximum power consumption in this mode of 300 µW.  
All chip inputs and outputs are TTL-compatible, and opera-  
tion is from a single 5V supply. The AS7C256 is packaged  
in all high volume industry standard packages.
