CY7C53120L8 General Description

The 3.3V Neuron chip (CY7C53120L8/3150L) is a low-power version of the 5V Neuron chip with a number of feature enhancements. The CY7C53120L8/3150L Neuron chip implements a device for LonWorks distributed intelligent control 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 microcontrollers.

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 memo (CY7C53150L). The firmware also contains 38 preprogrammed 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.
