GENERAL PRODUCT DESCRIPTION The ES29DL320 is a 32 megabit, 3.0 volt-only flash memory device, organized as 4M x 8 bits (Byte mode) or 2M x 16 bits (Word mode) which is configurable by BYTE#. Eight boot sectors and sixty three main sectors with uniform size are provided : 8K bytes x 8 and 64K bytes x 63. The device is manufactured with ESI’s proprietary, high performance and highly reliable 0.18um CMOS flash technology. The device can be programmed or erased in-system with standard 3.0 Volt Vcc supply (2.7V-3.6V) and can also be programmed in standard EPROM programmers. The device offers minimum endurance of 100,000 program/erase cycles and more than 20 years of data retention. The ES29DL320 offers access time as fast as 70ns or 90ns, allowing operation of high-speed microprocessors without wait states. Three separate control pins are provided to eliminate bus contention : chip enable (CE#), write enable (WE#) and output enable (OE#). All program and erase operation are automatically and internally performed and controlled by embedded program/erase algorithms built in the device. The device automatically generates and times the necessary high-voltage pulses to be applied to the cells, performs the verification, and counts the number of sequences. Some status bits (DQ7, DQ6 and DQ5) read by data# polling or toggling between consecutive read cycles provide to the users the internal status of program/erase operation: whether it is successfully done or still being progressed. Therefore, this lock indicator bit (DQ7) can be properly used to avoid that any customer-lockable part is used to replace a factory-locked part. The extra security sector is an extra memory space for customers when it is used as a customer-lockable version. So, it can be read and written like any other sectors. But it should be noted that the number of E/ W(Erase and Write) cycles is limited to 300 times (maximum) only in the Security Sector. Special services such as ESN and factory-locked are available to customers ( ESI’s Special-Code service ) The ES29DL320 is completely compatible with the JEDEC standard command set of single power sup.
