... SUMMARY DESCRIPTION The M58LW032D Mbit (4Mb 2Mb x16) non-volatile memory that can be read, erased and reprogrammed. These operations can be per- formed using a single low voltage (2.7V to 3.6V) core supply. The memory is divided into 32 blocks of 1Mbit that can be erased independently possible to preserve valid data while old data is erased ...

... M58LW032D BUS OPERATIONS There are five standard bus operations that control the memory. Each of these is described in this section, see Table 3., Bus Operations, for a sum- mary. On Power-up or after a Hardware Reset the mem- ory defaults to Read Array mode (Page Read). Typically glitches of less than 5ns on Chip Enable or Write Enable are ignored by the memory and do not affect bus operations ...
Page 13
... READ MODES Read operations in the M58LW032D are asyn- chronous. The device outputs the data corre- sponding to the address latched, that is the memory array, Status Register, Common Flash In- terface, Electronic Signature or Block Protection Status depending on the command issued. During read operations, if the bus is inactive for a ...
Page 14
... M58LW032D COMMAND INTERFACE All Bus Write operations to the memory are inter- preted by the Command Interface. Commands consist of one or more sequential Bus Write oper- ations. The Commands are summarized in 4., Commands. Refer to Table 4. with the text descriptions below. After power- Reset operation the memory enters Read mode ...
