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.
