GENERAL DESCRIPTION

The Pm25LV010/020/040 are 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, 33 MHz in fast

read mode and the bottom 4 Kbyte sector into four smaller 1 Kbyte sectors features. 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 Pm25LV010-33 is backward compatible to their

predecessors Pm25LV010-25.

The Pm25LV010/020/040 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 Pm25LV010 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 Pm25LV010/020/040 are manufactured on PMC’s advanced nonvolatile CMOS technology, pFLASH™. The

devices are offered in 8-pin SOIC and 8-contact WSON packages with operation frequency up to 33 MHz in fast read

and 33 MHz in normal read mode.
