... A12 DQ7 AI01378 DESCRIPTION The M29F040 is a non-volatile memory that may be erased electrically at the block level, and pro- grammed Byte-by-Byte. The interface is directly compatible with most mi- A11 32 croprocessors. PLCC32 and TSOP32 (8 x 20mm) A9 packages are available. Both normal and reverse A8 pin outs are available for the TSOP32 package ...

... M29F040 Memory Blocks The memory blocks of the M29F040 are shown in Figure 3. The memory array is divided in 8 uniform blocks of 64 Kbytes. Each block can be erased separately or any combination of blocks can be erased simultaneously. The Block Erase operation is managed automatically by the P/E.C. The opera- tion can be suspended in order to read from any other block, and then resumed ...

... Bit will stop toggling between 0.1 s and 15 s after the Erase Suspend (ES) command has been writ- ten. The M29F040 will then automatically set to Read Memory Array mode. When erase is suspended, Read from blocks being erased will output invalid data, Read from block not being erased is valid. ...
