MA9264
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.
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.
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.
