Type

Name and Function

A0–A16

INPUT

ADDRESS INPUTS for memory addresses. Addresses are internally

latched during a write cycle.

DQ0–DQ7

INPUT/OUTPUT

DATA INPUT/OUTPUT: Inputs data during memory write cycles; outputs

data during memory read cycles. The data pins are active high and float to

tri-state off when the chip is deselected or the outputs are disabled. Data is

internally latched during a write cycle

CE#

INPUT

CHIP ENABLE: Activates the device's control logic, input buffers, decoders

and sense amplifiers. CE# is active low; CE# high deselects the memory

device and reduces power consumption to standby levels.

OE#

INPUT

OUTPUT ENABLE: Gates the devices output through the data buffers

during a read cycle. OE# is active low.

WE#

INPUT

WRITE ENABLE: Controls writes to the control register and the array. Write

enable is active low. Addresses are latched on the falling edge and data is

latched on the rising edge of the WE# pulse.

Note: With VPP ≤ 6.5 V, memory contents cannot be altered.
