8/90

The M29W640G has an extra block, the Extended Block, of 128 words in x16 mode or of

256 bytes in x8 mode that can be accessed using a dedicated command. The Extended

Block can be protected and so is useful for storing security information. However the

protection is not reversible, once protected the protection cannot be undone.

The M29W640GT, M29W640GB, M29W640GH and M29W640GL, are offered in TSOP48

(12x 20mm), TSOP56 (14x 20mm), TFBGA48 (6 x8mm, 0.8mm pitch), and TBGA64 (10x

13mm, 1mm pitch) packages.

In order to meet environmental requirements, Numonyx offers the M29W640GH,

M29W640GL, M29W640GT and M29W640GB 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 ratings related to soldering conditions are also marked on the inner box label.

The memory is delivered with all the bits erased (set to 1).
