It incorporates, 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 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 CY7C531x0 is manufactured using the state-of-the-art 0.35-mm Flash technology, providing to the 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 the 10-KB 10-KB ROM (CY7C53120E2 CY7C53120E2), 12-KB 12-KB ROM (CY7C53120E4 CY7C53120E4), or off-chip memory (CY7C53150 CY7C53150). The firmware also contains 34 preprogrammed I/O drivers, greatly simplifying application programming. The application program is stored in the EEPROM memory (CY7C53120 CY7C53120), and/or off-chip memory (CY7C53150 CY7C53150), and may be updated by downloading over the network. The CY7C53150 CY7C53150 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 programs can take advantage of this external memory capability. The CY7C53150 CY7C53150 Neuron Chip is an exact replacement for the Motorola MC143150Bx and Toshiba TMPN3150B1 TMPN3150B1 devices. The CY7C53120E2 CY7C53120E2 Neuron Chip is an exact replacement for the Motorola MC143120E2 MC143120E2 device, since it contains the same firmware in ROM.

Memory Usage All Neuron Chips require system firmware to be present when they are powered up. In the case of the CY7C53120 CY7C53120 family, this firmware is pre-programmed in the factory in an on-board ROM. In the case of the CY7C53150 CY7C53150, the system firmware must be present in the first 16KB of an off-board non-volatile memory such as flash, EPROM, EEPROM, or NVRAM. These devices must be programmed in a device programmer before board assembly. Because the system firmware implements the network protocol, it cannot itself be downloaded over the network. EEPROM Retention and Endurance Data and code stored in EEPROM is guaranteed to be retained for at least 10 years after being written. If it is desired to extend the guaranteed retention time, EEPROM contents may be periodically refreshed. The system firmware supports EEPROM refreshing under software control and also by an external network management tool. EEPROM may be written up to 10,000 times with no data loss. An erase/write cycle takes 20 msec. The system firmware extends the effective endurance of EEPROM in two ways. If the data being written to a byte of EEPROM is the same as the data already present in that byte, the firmware does not perform the physical write. So for example, an application that sets its own address in EEPROM after every reset will not use up any write cycles if the address has not changed. In addition, system firmware version 12 or higher is able to aggregate writes to 8 successive address locations into a single write. So for example, if 4 KB of code is downloaded over the network, the firmware would execute only 512 writes rather than 4,096. For the CY7C53120 CY7C53120 family, the user application program is stored in on-board EEPROM memory. It may be programmed using a device programmer before board assembly, or may be downloaded and updated over the LonTalk network from an external network management tool. For the CY7C53150 CY7C53150, the user application program is stored in on-board EEPROM and also in off-chip memory. The user program may initially be programmed into the off-chip memory device using a device programmer. If the external memory device is writeable (e.g. flash), the user application program may 3 CY7C53150 CY7C53150 CY7C53120 CY7C53120 PRELIMINARY .
