• Description: 4-Megabit 2.7-volt Only Serial DataFlash
• Manufacturer: ATMEL [ATMEL Corporation]

RESET: A low state on the reset pin (RESET) will terminate
the operation in progress and reset the internal state
machine to an idle state. The device will remain in the reset
condition as long as a low level is present on the RESET
pin. Normal operation can resume once the RESET pin is
brought back to a high level.
The device also incorporates an internal power-on reset
circuit; therefore, there are no restrictions on the RESET
pin during power-on sequences.
READY/BUSY: This open drain output pin will be driven
low when the device is busy in an internally self-timed oper-
ation. This pin, which is normally in a high state (through an
external pull-up resistor), will be pulled low during program-

The busy status indicates that the Flash memory array and
one of the buffers cannot be accessed; read and write
operations to the other buffer can still be performed.
Power On/Reset State
When power is first applied to the device, or when recover-
ing from a reset condition, the device will default to SPI
mode 3. In addition, the SO pin will be in a high impedance
state, and a high to low transition on the CS pin will be
required to start a valid instruction. The SPI mode will be
automatically selected on every falling edge of CS by sam-
pling the inactive clock state.
