Description

The  AS7C1024A and AS7C31024A is a high performance CMOS 1,048,576-bit Static Random Access Memory (SRAM) device organized as 131,072 words x 8 bits. It is designed for memory applications where fast data access, low power, and simple interfacing are desired.


Equal address access of AS7C1024A-20STC and cycle times (tAA , t RC , tWC ) of 10/12/15/20 ns with output enable access times (tOE  ) of 5/6/7/8 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 the devices enter standby mode. If inputs are still toggling, the device will consume I  power. If the bus is SB static, then full standby power is reached (ISB1 ). For example, the  AS7C31024A is guaranteed not to exceed 55mW under nominal full standby  conditions.


A write cycle is accomplished by asserting write enable (WE ) and both chip enables (CE1 , CE2). Data on the input pins I/O0 through 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 outputs have 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.
