NOTES:

1. Q7 : WRITE STATE MACHINE STATUS

1 = READY, 0 = BUSY

Q4 : PROGRAM FAIL STATUS

1 = FAIL IN PROGRAM, 0 = SUCCESSFUL PROGRAM

Q3=0 = RESERVED FOR FUTURE ENHANCEMENTS.

These bits are reserved for future use ; mask them out when polling the Status Register.

2. PROGRAM STATUS is for the status during Page Programming.

3. FAIL STATUS bit(Q4) is provied during Page Program mode.

STATUS REGISTER TABLE

LOW VCC WRITE INHIBIT

To avoid initiation of a write cycle during VCC power-up

and power-down, a write cycle is locked out for VCC

less than VLKO(= 3.2V , typically 3.5V). If VCC < VLKO,

the command register is disabled and all internal pro-

gram circuits are disabled. Under this condition the

device will reset to the read mode. Subsequent writes

will be ignored until the VCC level is greater than VLKO.

It is the user's responsibility to ensure that the control

pins are logically correct to prevent unintentional write

when VCC is above VLKO.

WRITE PULSE "GLITCH" PROTECTION

Noise pulses of less than 10ns (typical) on CE will not

initiate a write cycle.

LOGICAL INHIBIT

Writing is inhibited by holding any one of OE = VIL,CE =

VIH. To initiate a write cycle CE must be a logical zero

while OE is a logical one, and BYTE/VPP=10V.

NOTICE:

Stresses greater than those listed under ABSOLUTE MAXI-

vice. This is stress rating only and functional operational

sections of this specification is not implied. Exposure to ab-

solute maximum rating conditions for extended period may

affect reliability.
