Note: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may
cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions
above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating condi-
tions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant qual-
ity documents.
2. Minimum Voltage may undershoot to –2V during transition and for less than 20ns during transitions.

The blocks in the memory are asymmetrically ar-
ranged, see Tables 3 and 4, Block Addresses. The
first or last 64 Kbytes have been divided into four
additional blocks. The 16 Kbyte Boot Block can be
used for small initialization code to start the micro-
processor, the two 8 Kbyte Parameter Blocks can
be used for parameter storage and the remaining
32K is a small Main Block where the application
may be stored.
Chip Enable, Output Enable and Write Enable sig-
nals control the bus operation of the memory.
They allow simple connection to most micropro-
cessors, often without additional logic.
The memory is offered in TSOP48 (12 x 20mm)
and SO44 packages and it is supplied with all the
bits erased (set to ’1’).
In order to meet environmental requirements, ST
offers the M29W200B in ECOPACK® packages.
ECOPACK packages are Lead-free. The category
of second Level Interconnect is marked on the
package and on the inner box label, in compliance
with JEDEC Standard JESD97. The maximum rat-
ings related to soldering conditions are also
marked on the inner box label.
ECOPACK is an ST trademark. ECOPACK speci-
fications are available at: www.st.com.
