Write Enable: Determines if a given cycle is a WRITE
cycle. If WE# is LOW, the cycle is either a WRITE to the
command execution logic (CEL) or to the memory array.
Addresses and data are latched on the rising edge of the
WE# pulse.
Chip Enable: Three CE pins enable the use of multiple
Flash devices in the system without requiring additional
logic. The device can be configured to use a single CE
signal by tying CE1 and CE2 to ground and then using
CE0 as CE. Device selection occurs with the first edge of
CE0, CE1, or CE2 (CEx) that enables the device. Device
deselection occurs with the first edge of CEx that
disables the device (see Table 1).
Reset/Power-Down: When LOW, RP# clears the status
register, sets the ISM to the array read mode, and places
the device in deep power-down mode. All inputs,
including CEx, are “Don’t Care,” and all outputs are
High-Z. RP# must be held at V
of operation.
Output Enables: Enables data ouput buffers when LOW.
When OE# is HIGH, the output buffers are disabled.
Address inputs during READ and WRITE operations. A0 is
only used in x8 mode. A22 (pin 1, ball A8) is only
available on the 64Mb and 128Mb devices. A23 (pin 30,
ball G1) is only available on the 128Mb device.
BYTE# LOW places the device in the x8 mode. BYTE#
HIGH places the device in the x16 mode and turns off
the A0 input buffer. Address A1 becomes the lowest
order address in x16 mode.
