PM49FL004T Flash Memory


The Pm49FL002/ Pm49FL004 are 2 Mbit/4 Mbit 3.3 Volt-only Flash Memories used as BIOS in PCs and Notebooks. These devices are designed to use a single low voltage, ranging from 3.0 Volt to 3.6 Volt, power supply to perform insystem or off-system read, erase and program operations. The 12.0 Volt VPP power supply are not required for the program and erase operations of devices. The devices conform to Intel® Low Pin Count (LPC) Interface specification revision 1.1 and also read-compatible with Intel 82802 Firmware Hub (FWH) for most PC and Notebook applications.
