... Document #: 38-10001 Rev. *F Services at every layer of the OSI networking reference model are implemented in the LonTalk firmware based protocol stored in 10-KB ROM (CY7C53120E2), 12-KB ROM (CY7C53120E4), or off-chip memory (CY7C53150). The firmware also contains 34 preprogrammed I/O drivers, greatly simplifying application programming. The application program is stored in the Flash memory (CY7C53120) and/or off-chip memory (CY7C53150), and may be updated by downloading over the network ...
