Description

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 manu-

facturing. 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).
