SUMMARY DESCRIPTION

M58LW128 is a 128 Mbit (8Mb x16 or 4Mb x32) 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. On power-up the memory defaults to Read mode with an asynchronous bus where it can be read in the same way as a non-burst Flash memory.
