DESCRIPTION  
RP  
The M29F400 is a non-volatile memory that may  
be erased electrically at the block or chip level and  
programmed in-system on a Byte-by-Byte or Word-  
by-Word basis using only a single 5V VCC supply.  
For Program and Erase operations the necessary  
high voltages are generated internally. The device  
can also be programmed in standard program-  
mers.

The array matrix organisation allows each block to  
be erased and reprogrammed without affecting  
other blocks. Blocks can be protected against pro-
