Address Inputs used to select one of the 128K address lo-
cations. Sampled at the rising edge of the CLK. A
to the two-bit burst counter.
Byte Write Inputs, active LOW. Qualified with WE to conduct
writes to the SRAM. Sampled on the rising edge of CLK.
Write Enable Input, active LOW. Sampled on the rising edge
of CLK if CEN is active LOW. This signal must be asserted LOW
to initiate a write sequence.
Advance/Load Input. Used to advance the on-chip address
counter or load a new address. When HIGH (and CEN is as-
serted LOW) the internal burst counter is advanced. When
LOW, a new address can be loaded into the device for an ac-
cess. After being deselected, ADV/LD should be driven LOW in
order to load a new address.
Clock Input. Used to capture all synchronous inputs to the de-
vice. CLK is qualified with CEN. CLK is only recognized if CEN
is active LOW.
Chip Enable 1 Input, active LOW. Sampled on the rising edge
of CLK. Used in conjunction with CE
lect the device.
Chip Enable 2 Input, active HIGH. Sampled on the rising edge
of CLK. Used in conjunction with CE
the device.
