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 V_PPpower 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.

The devices have a standard microprocessor interface as well as a JEDEC standard pin-out/command set. The

program operation is executed by issuing the program command code into command register. The internal control

logic automatically handles the programming voltage ramp-up and timing. The erase operation is executed by

issuing the chip erase, block, or sector erase command code into command register. The internal control logic

automatically handles the erase voltage ramp-up and timing. The preprogramming on the array which has not been

programmed is not required before an erase operation. The devices offer Data# Polling and Toggle Bit functions, the

progress or completion of program and erase operations can be detected by reading the Data# Polling on I/O7 or

the Toggle Bit on I/O6.

The Pm39LV512/010/020/040 are manufactured on PMC’s advanced nonvolatile CMOS technology, P-FLASH™.

The devices are offered in 32-pin VSOP and PLCC packages with access time of 55 and 70 ns.
