Flash Address inputs
Flash multiplexed Address and Data
Flash Chip-enable input. Asynchronous relative to CLK for Burst Mode
Flash Output Enable input. Asynchronous relative to CLK for Burst mode.
Flash Write Enable input
Flash device power supply (1.7 V to 1.95 V)
Flash Input/Output Buffer power supply
Flash Ground
Flash ready output. Indicates the status of the Burst read. V
= data valid.
Flash Clock. The first rising edge of CLK in conjunction with AVD# low latches the
address input and activates burst mode operation. After the initial word is output,
subsequent rising edges of CLK increment the internal address counter. CLK
should remain low during asynchronous access.
Flash Address Valid input. Indicates to device that the valid address is present on
the address inputs. V
mode, causes starting address to be latched on rising edge of CLK. V
ignores address inputs
Flash hardware reset input. V
Flash hardware write protect input. V
the four outermost sectors
Flash accelerated input. At V
device in unlock bypass mode. At V
Should be at V
