M29W040
DESCRIPTION
The M29W040 is a non-volatile memory that may be erased electrically at the block level, and programmed Byte-by-Byte. The interface is directly patible with most microprocessors. PLCC32, TSOP32 (8 x 20mm)and TSOP32 (8 x 14mm) packages are available. Both normal and reverse pin outs are available for the TSOP32 (8 x 20mm) package. Organisation The Flash Memory organisationis 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...
