GENERAL DESCRIPTION
The Pm25LV512A/010A/020/040 are 512Kbit/1 Mbit/2 Mbit/4 Mbit 3.0 Volt-only Serial Peripheral Interface (SPI)
Flash memories. The devices are designed to support 33 MHz fastest clock rate in the industry in normal read
mode, 100 MHz in fast read mode and the bottom 4 Kbyte sector into four smaller 1 Kbyte sectors features(except
Pm25LV512A). The devices use a single low voltage, ranging from 2.7 Volt to 3.6 Volt, power supply to perform
read, erase and program operations. The devices can be programmed in standard EPROM programmers as well.
The Pm25LV512A/010A is backward compatible to their predecessors Pm25LV512/010.
The Pm25LV512A/010A/020/040 are accessed through a 4-wire SPI Interface consists of Serial Data Input (Sl),
Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. The devices support page program
mode, 1 to 256 bytes data can be programmed into the memory in one program operation. The memory of
Pm25LV512A/010A is divided into uniform 4 Kbyte sectors or uniform 32 Kbyte blocks (sector group - consists of
eight adjacent sectors) for data or code storage. The memory of Pm25LV020/040 are divided into uniform 4 Kbyte
sectors or uniform 64 Kbyte blocks (sector group - consists of sixteen adjacent sectors). The devices have an
innovative feature to configure the bottom 4 Kbyte sector into four smaller 1 Kbyte sectors for eliminating additional
serial EEPROM needed for storing data. This is a further cost reduction for overall system.
The Pm25LV512A/010A/020/040 are manufactured on pFLASH™’s advanced nonvolatile technology. The devices
are offered in 8-pin SOIC, 8-contact WSON and 8-pin PDIP (Pm25LV040) packages with operation frequency up to
100 MHz in fast read and 33 MHz in normal read mode.

DESCRIPTION
Chip Enable: CE# goes low activates the devices internal circuitries for
device operation. CE# goes high deselects the devices and switches into
standby mode to reduce the power consumption. When the devices are not
selected, data will not be accepted via the serial input pin (Sl), and the
serial output pin (SO) will remain in a high impedance state.

Device Power Supply
Write Protect: A hardware program/erase protection for all or partial of
memory array. When the WP# pin is pulled to low, whole or partial of
memory array is write protected depends on the setting of BP2, BP1 and
BP0 bits in the Status Register. When the WP# is pulled high, the devices
are not write protected.
Hold: Pause serial communication with the master device without resetting
the serial sequence.
