General Description

The A29DL324 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.

The A29DL324 can be read while its contents are being

erased or programmed. The memory cell is divided into two

banks. While sectors in one bank are being erased or

programmed, data can be read from the other bank thanks

to the simultaneous execution architecture. The banks are

8 Mbits and 24 Mbits.

Because the A29DL324 enables the boot sector to be

erased, it is ideal for storing a boot program. In addition,

program code that controls the flash memory can be also

stored, and the program code can be programmed or

erased without the need to load it into RAM. Eight small

sectors for storing parameters are provided, each of which

can be erased in 8 Kbytes units.

Once a program or erase command sequence has been

executed, an automatic program or automatic erase

function internally executes program or erase and

verification automatically.

Because the A29DL324 can be electrically erased or

programmed by writing an instruction, data can be

reprogrammed on-board after the flash memory has been

installed in a system, making it suitable for a wide range of

applications.

This flash memory comes in two types. The T type has a

boot sector located at the highest address (sector) and the

B type has a boot sector at the lowest address (sector).
