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-
croprocessors. PLCC32 and TSOP32 (8 x 20mm)
packages are available. Both normal and reverse
pin outs are available for the TSOP32 package.
Organisation
The Flash Memory organisation is 512K x8 bits with
Address lines A0-A18 and Data Inputs/Outputs
DQ0-DQ7. Memory control is provided by Chip
Enable, Output Enable and Write Enable Inputs.
Erase and Program are performed through the
internal Program/Erase Controller (P/E.C.).
Data Outputs bits DQ7 and DQ6 provide polling or
toggle signals during Automatic Program or Erase
to indicate the Ready/Busy state of the internal
Program/Erase Controller.
Memory Blocks
Erasure of the memory is in blocks. There are 8
uniform blocks of 64 Kbytes each in the memory
address space. Each block can be programmed
and erased over 100,000 cycles. Each uniform
block may separately be protected and unpro-
