Description

The M29DW324DB is a 32 Mbit (4Mb x8 or 2Mbx16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. On power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or EPROM.

The M29DW324DB features an asymmetrical block architecture. The M29DW324D has an array of 8 parameter and 63 main blocks and is divided into two Banks, A and B, providing Dual Bank operations. While programming or erasing in Bank A, read operations are possible in Bank B and vice versa. Only one bank at a time is allowed to be in program or erase mode. The bank architecture is summarized in Table 2. M29DW324DT locates the Parameter Blocks at the top of the memory address space while the M29DW324DB locates the Parameter Blocks starting from the bottom.
