A29DL323 Overview
The A29DL323 is a flash memory organized of 33,554,432 bits and 71 sectors. Sectors of this memory can be erased at a low voltage (2.7 to 3.6 V) supplied from a single power source, or the contents of the entire chip can be erased. Two modes of memory organization, BYTE mode (4,194,304 words × 8 bits) and WORD mode (2,097,152 words × 16 bits), are selectable so that the memory can be programmed in byte or word units.
