SIGNAL DEFINITIONS
A0-12
Address input pins which select a particular eight bit word within
the memory array.
D0-7
Bidirectional data pins which serve as data outputs during a read
operation and as data inputs during a write operation.
CS
Chip Select, which, at low level, activates a read or write
operation. When at a high level it defaults the SRAM to a
prechargencondition and holds the data output drivers in a high
impedance state.
WE
Write Enable which when at a low level enables a write and holds
data output drivers in a high impedance state. When at a high
level, it enables a read.
OE
Output Enable which when at a high level holds the data output
drivers in a high impedance state. When at a low level, data
output driver state is defined by
CS
,
WE
and CE. If this signal is
not used it must be connected to VSS.
CE
Chip Enable which when at a high level allows normal operation.
When at a low level it defaults the SRAM to a precharge
condition, disables the input circuits on all input pins and holds
the data output drivers in a high impedance state. If this signal
is not used it must be connected to VDD.
