WRITE ALL (WRAL)

The Write All (WRAL) instruction will write the entire

memory array with the data specified in the command.

The self-timed auto-erase and programming cycle is

initiated by the rising edge of CLK on the last data bit.

Clocking of the CLK pin is not necessary after the

device has entered the WRAL cycle. The WRAL

command does include an automatic ERAL cycle for

the device. Therefore, the WRAL instruction does not

require an ERAL instruction but the chip must be in the

EWEN status.

The DO pin indicates the READY/BUSY status of the

device if CS is brought high after a minimum of 250 ns

low (TCSL).

Note:

Issuing a Start bit and then taking CS low

will clear the READY/BUSY status from

DO.

VCC must be

≥ 4.5V for proper operation of WRAL.
