NAME AND FUNCTION
ADDRESS INPUTS: for memory addresses. Addresses are internally
latched during a write cycle.
LOW-BYTE DATA BUS: Input data and commands during Command Interface
Register(CIR) write cycles. Outputs array,status and identifier data in the
appropriate read mode. Floated when the chip is de-selected or the outputs
are disabled.
HIGH-BYTE DATA BUS: Inputs data during x 16 Data-Write operations.
Outputs array, identifier data in the appropriate read mode; not used for status
register reads. Floated when the chip is de-selected or the outputs are
disabled
Selects between high-byte data INPUT/OUTPUT(BYTE = HIGH) and LSB
ADDRESS(BYTE = LOW)
CHIP ENABLE INPUTS: Activate the device's control logic, Input buffers,
decoders and sense amplifiers. With CE high, the device is deselected and
power consumption reduces to Standby level upon completion of any current
program or erase operations. CE must be low to select the device.
OUTPUT ENABLES: Gates the device's data through the output buffers
during a read cycle OE is active low.
WRITE ENABLE: Controls writes to the Command Interface Register(CIR).
WE is active low.
WRITE PROTECT: Top or Bottom sector can be protected by writing a non-
volatile protect-bit for each sector. When WP is high, all sectors can be
programmed or erased regardless of the state of the protect-bits.
BYTE ENABLE: BYTE Low places device in x8 mode. All data is then input
or output on Q0-7 and Q8-14 float. AddressQ15/A-1 selects between the high
and low byte. BYTE high places the device in x16 mode, and turns off the Q15/
A-1 input buffer. Address A0, then becomes the lowest order address.
