The AS7C164 is a high performance CMOS 65,536-bit Static Random Access Memory (SRAM) device organized as 8,192 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 (t
AA
, t
RC
, t
WC
) of 12/15/20 ns with output enable access times (t
OE
) of 3/4/5 ns are ideal for high
performance applications. Active high and low chip enables ( CE1, CE2) permit easy memory expansion with multiple-bank memory
systems.
When CE1 is High or CE2 is Low the device enters standby mode. The standard AS7C164 is guaranteed not to exceed 11.0 mW power
consumption in standby mode, and typically requires only 250 μW; it offers 2.0V data retention with maximum power of 120 μW.
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 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 chip
drives I/O pins with the data word referenced by the input address. When either chip enable or output enable is inactive, or write enable is
active, output drivers stay in high-impedance mode.
All chip inputs and outputs are TTL-compatible, and operation is from a single 5V supply. The AS7C164 is packaged in all high volume
industry standard packages.
