Programmable Microelectronics PM49FL002T-33VC
The Pm49FL002/004 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.FEATURES
