Functional Description
The CY53150 is a Neuron Chip which implements a node for
the LonWorks distributed intelligent control networks. It in-
corporates, on a single chip, the necessary communication
and control functions, both in hardware and firmware, that fa-
cilitate the design of a LonWorks node.
The CY53150 is manufactured using the state-of-the-art
0.35-
μ
m Flash technology, providing to the designers the most
cost-effective Neuron Chip solution.
The CY53150 incorporates an external memory interface,
which can address up to 64 KB, with 6 KB of the address space
being mapped internally. LonWorks nodes that require large
application codes can take advantage of the external memory
capability. The LonTalk protocol firmware is also stored in the
external memory, requiring a space of 16 KB. The configura-
tion data are stored in the on-chip EEPROM memory.
The CY53150 contains a very flexible 5-pin communication
port, that can be configured to interface to 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 CY53150 Neuron Chip is a drop-in replacement for the
Motorola MC143150B2 device.
