*NOTICE: Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.

Notes: 1. The DATA FORMAT in each bus cycle is as follows:
I/O15 - I/O8 (Don’t Care); I/O7 - I/O0 (Hex)
2. The 8K word boot sector has the address range
00000H to 01FFFH.
3. Either one of the Product ID Exit commands
can be used.
4. SA = sector addresses:
SA = 03XXX for PARAMETER BLOCK 1
SA = 05XXX for PARAMETER BLOCK 2
SA = 1FXXX for MAIN MEMORY ARRAY
5. When the boot block programming lockout feature is not
enabled, the boot block and the main memory block will erase
sense: if V
CC
is below 1.8V (typical), the program function
is inhibited. (b) V
CC
power on delay: once V
CC
has
reached the V
CC
sense level, the device will automat-
ically time out 10 ms (typical) before programming. (c)
Program inhibit: holding any one of OE low, CE high or
WE high inhibits program cycles. (d) Noise filter: pulses of
less than 15 ns (typical) on the WE or CE inputs will not
initiate a program cycle.
INPUT LEVELS:
While operating with a 2.7V to 3.6V
power supply, the address inputs and control inputs (OE,
CE, and WE) may be driven from 0 to 5.5V without ad-
versely affecting the operation of the device. The I/O lines
can only be driven from 0 to V
CC
+ 0.6V.
