Functional Description
The CY7C531x0 Neuron
錚?/div>
chip implements a node for
LonWorks
錚?/div>
distributed intelligent control networks. It incorpo-
rates, on a single chip, the necessary communication and
control functions, both in hardware and firmware, that facilitate
the design of a LonWorks node.
The CY7C531x0 contains a very flexible five-pin communi-
cation port that can be configured to interface with a wide
variety of media transceivers at a wide range of data rates. The
most common transceiver types are twisted-pair, powerline,
RF, IR, fiber-optics, and coaxial.
The CY7C531x0 is manufactured using state-of-the-art
0.35-碌m Flash technology, providing to designers the most
cost-effective Neuron chip solution.
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.
The CY7C53150 incorporates an external memory interface
that can address up to 64 KB with 6 KB of the address space
mapped internally. LonWorks nodes that require large appli-
cation programs can take advantage of this external memory
capability.
The CY7C53150 Neuron chip is an exact replacement for the
Motorola MC143150Bx and Toshiba TMPN3150B1 devices.
The CY7C53120E2 Neuron chip is an exact replacement for
the Motorola MC143120E2 device since it contains the same
firmware in ROM.
