Functional Description
The 3.3V Neuron
version of the 5V Neuron chip with a number of feature
enhancements. The CY7C53120L8/3150L Neuron chip imple-
ments a device for LonWorks
networks. It incorporates, on a single chip, the necessary
communication and control functions, both in hardware and
firmware, that facilitate the design of a LonWorks device.
The CY7C53120L8/3150L supports all the functionality of the
5V CY7C531x0 Neuron chip. Additionally it features 4KBytes
of RAM, 8KBytes of Flash memory (CY7C53120L8), and
hardware UART/SPI. The CY7C53120L8/3150L has an 11-pin
configurable I/O block. The I/Os are all 5V-tolerant to allow
interfacing to TTL Compatible 5V components and microcon-
The CY7C53120L8/3150L contains a very flexible five-pin
communication port that can be configured to interface with a
wide variety of media transceivers at a wide range of data
rates. The communication port can operate at either 3.3V or
5V. In 5V mode the communication port is completely
backward compatible with existing 5V transceivers. The most
common transceiver types are twisted-pair, powerline, RF, IR,
fiber-optics, and coaxial.
The CY7C53150L incorporates an external memory interface
that can address up to 56KBytes with 8KBytes of the address
space mapped internally. LonWorks devices that require large
application programs can take advantage of this external
memory capability.
Services at every layer of the OSI networking reference model
are implemented in the LonTalk firmware-based protocol
stored in 16KBytes ROM (CY7C53120L8), or off-chip memory
(CY7C53150L). The firmware also contains 38 prepro-
grammed I/O drivers, simplifying application programming.
The application program is stored in the Flash memory
(CY7C53120L8) and/or off-chip memory (CY7C53150L), and
may be updated by downloading over the network.
