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
PP
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.
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 pFLASH™’s advanced nonvolatile CMOS technology. The de-
vices are offered in 32-pin VSOP and PLCC packages with 70 ns access time.

实验室仪器仪表使用静电仪器的一般常识
静电仪器通常是在高电压(104V数量级)、微电量(10-6库仑数量级)条件下工作,因此,对绝缘性能的要求很高。可以说,静电实验成败的关键是绝缘问题。绝缘的目的是尽量减少电荷的流散。   ......
