FUNCTIONAL DESCRIPTION
The AS7C256 is a high performance CMOS 262,144-bit
Static Random Access Memory (SRAM) organized as
32,768 words × 8 bits. It is designed for memory applications where fast data access, low power, and simple interfacing are desired.
A write cycle is accomplished by asserting chip enable (CE)
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 (tAA, tRC, tWC) of
10/12/15/20/25/35 ns with output enable access times (tOE)
of 3/3/4/5/6/8 ns are ideal for high performance applications. A chip enable (CE) input permits easy memory
expansion with multiple-bank memory organizations.
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 referenced by the input address. When chip enable or output
enable is HIGH, or write enable is LOW, output drivers stay
in high-impedance mode.
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 guaranteed 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 operation is from a single 5V supply. The AS7C256 is packaged
in all high volume industry standard packages.

During VCC power-up, a pull-up resistor to VCC on CE is required to meet ISB specification.
This parameter is sampled and not 100% tested.
For test conditions, see AC Test Conditions, Figures A, B, C.
tCLZ and tCHZ are specified with CL = 5pF as in Figure C. Transition is measured ±500mV from steady-state voltage.
This parameter is guaranteed but not tested.
WE is HIGH for read cycle.
CE and OE are LOW for read cycle.
Address valid prior to or coincident with CE transition LOW.
All read cycle timings are referenced from the last valid address to the first transitioning address.
CE or WE must be HIGH during address transitions.
All write cycle timings are referenced from the last valid address to the first transitioning address.
