GW
Input-
Synchronous
Global Write: This active LOW input allows a full 18-bit Write
to occur independent of the BWE and WEn lines and must
meet the set-up and hold times around the rising edge of CLK.
4K
89
CLK
Input-
Synchronous
Clock: This signal registers the addresses, data, chip enables,
write control and burst control inputs on its rising edge. All
synchronous inputs must meet set-up and hold times around
the clock
’
s rising edge.
4E
98
CE
Input-
Synchronous
Chip Enable: This active LOW input is used to enable the
device and to gate ADSP
6B
92
CE2
Input-
Synchronous
Chip Enable: This active LOW input is used to enable the
device.
2B
97
CE2
input-
Synchronous
Chip enable: This active HIGH input is used to enable the
device.
4F
86
OE
Input
Output Enable: This active LOW asynchronous input enables
the data output drivers.
4G
83
ADV
Input-
Synchronous
Address Advance: This active LOW input is used to control the
internal burst counter. A HIGH on this pin generates wait cycle
(no address advance).
4A
84
ADSP
Input-
Synchronous
Address Status Processor: This active LOW input, along with
CE being LOW, causes a new external address to be registered
and a READ cycle is initiated using the new address.
4B
85
ADSC
Input-
Synchronous
Address Status Controller: This active LOW input causes de-
vice to be de-selected or selected along with new external ad-
dress to be registered. A Read or Write cycle is initiated de-
pending upon write control inputs.
3R
31
MODE
Input-
Static
Mode: This input selects the burst sequence. A LOW on this
pin selects Linear Burst. A NC or HIGH on this pin selects
Interleaved Burst.
