GENERAL DESCRIPTION

The Pm39LV512/010/020/040 are 512 Kbit/1 Mbit/2 Mbit/4 Mbit 3.0 Volt-only Flash Memories. These devices are designed to use a single low voltage, range from 2.7 Volt to 3.6 Volt, power supply to perform read, erase and program operations. The 12.0 Volt VPP power supply for program and erase operations are not required. The devices can be programmed in standard EPROM programmers as well.

The memory array of Pm39LV512 is divided into uniform 4 Kbyte sectors for data or code storage. The memory arrays of Pm39LV010/020/040 are divided into uniform 4 Kbyte sectors or uniform 64 Kbyte blocks (sector group - consists of sixteen adjacent sectors). The sector or block erase feature allows users to flexibly erase a memory area as small as 4 Kbyte or as large as 64 Kbyte by one single erase operation without affecting the data in others. The chip erase feature allows the whole memory array to be erased in one single erase operation. The devices can be programmed on a byte-by-byte basis after performing the erase operation.
