Product Summary
The PM49FL004T-33JCE is a 2 Mbit/4 Mbit 3.3 Volt-only Flash Memory used as BIOS in PCs and Notebooks. The PM49FL004T-33JCE is designed to use a single low voltage, ranging from 3.0 Volt to 3.6 Volt, power supply to perform in-system 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.
