The AT49LL080 is a Flash memory device designed to interface with the LPC bus for PC Applications. A feature of the AT49LL080 is the nonvolatile memory core. The high-performance memory is arranged in sixteen sectors (see page 11). The AT49LL080 supports two hardware interfaces: Low Pin Count (LPC) for in-system operation and Address/Address Multiplexed (A/A Mux) for programming during manufacturing. The IC (Interface Configuration) pin of the device provides the control between the interfaces. The interface mode needs to be selected prior to power-up or before return from reset (RST or INIT low to high transition).
