M58LW032A90N6T中文资料意法半导体数据手册PDF规格书

SUMMARY DESCRIPTION

The M58LW032 is a 32 Mbit (2Mb x16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed 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.
