Functional description  
The AS7C1024 and AS7C31024 are high performance CMOS 1,048,576-bit Static Random Access Memory (SRAM) devices  
organized as 131,072 words × 8 bits. It is designed for memory applications where fast data access, low power, and simple  
interfacing are desired.  
Equal address access and cycle times (tAA, tRC, tWC) of 10/ 12/ 15/ 20 ns with output enable access times (tOE) of 5/ 6/ 8/ 10 ns  
are ideal for high performance applications. Active high and low chip enables (CE1, CE2) permit easy memory expansion with  
multiple-bank systems.  
When CE1 is high or CE2 is low the devices enter standby mode. If inputs are still toggling, the device will consume I power.  
SB  
If the bus is static, then full standby power is reached (ISB1 or ISB2). For example, the AS7C31024 is guaranteed not to exceed  
0.33mW under nominal full standby conditions. All devices in this family will retain data when VCC is reduced as low as 2.0V.  
A write cycle is accomplished by asserting write enable (WE) and both chip enables (CE1, CE2). Data on the input pins I/ O0-  
I/ O7 is written on the rising edge of WE (write cycle 1) or the active-to-inactive edge of CE1 or CE2 (write cycle 2). To avoid  
bus contention, external devices should drive I/ O pins only after outputshave been disabled with output enable ( OE) or write  
enable (WE).  
A read cycle is accomplished by asserting output enable (OE) and both chip enables (CE1, CE2), with write enable (WE) high.  
The chips drive I/ O pins with the data word referenced by the input address. When either chip enable is inactive, output  
enable is inactive, or write enable is active, output drivers stay in high-impedance mode.
