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 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 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-µm 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 application 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.

In the case of the CY7C53120 family, this firmware is preprogrammed in the factory in an on-chip ROM. In the case of the CY7C53150, the system firmware must be present in the first 16 KB of an off-chip nonvolatile 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. For the CY7C53120 family, the user application program is stored in on-chip Flash memory. It may be programmed using a device programmer before board assembly, or may be Document #: 38-10001 Rev. *D Page 4 of 12 CY7C53150 CY7C53120 downloaded and updated over the LonTalk network from an external network management tool. For the CY7C53150, the user application program is stored in on-chip Flash Memory and also in off-chip memory. The user program may initially be programmed into the off-chip memory device using a device programmer. transceiver is responsible for encoding and decoding the data stream. In Differential Mode, pins CP0 and CP1 form a differential receiver with built-in programmable hysteresis and low-pass filtering. Pins CP2 and CP3 form a differential driver. Serial data is communicated using Differential Manchester encoding. The following tables describe the communications port when used in Differential Mode. Flash Memory Retention and Endurance Data and code stored in Flash Memory is guaranteed to be retained for at least 10 years for programming temperature range of –25°C to 85°C. The Flash Memory can typically be written 100,000 times without any data loss.[5] An erase/write cycle takes 20 ms. The system firmware extends the effective endurance of Flash memory in two ways. If the data being written to a byte of Flash memory 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 Flash memory after every reset will not use up any write cycles if the address has not changed. In addition, system firmware version 13.1 or higher is able to aggregate writes to eight successive address locations into a single write for CY7C53120E4 devices. For example, if 4 KB of code is downloaded over the network, the firmware would execute only 512 writes rather than 4,096. CP0 – CP1 ≥ Vhys + 200 mV CP0 VDD/2 CP1 ≤ 3 ns Figure 1.

It is important to note that external oscillators may typically take on the order of 5 ms to stabilize after power-up. The Neuron chip should be held in reset until the CLK1 input is stable. With some oscillators, this may require the use of a reset-stretching Low-Voltage Detection chip/circuit.

This feature prevents the corruption of nonvolatile memory during voltage drops. Communications Port The Neuron chip includes a versatile 5-pin communications port that can be configured in three different ways. In Single-Ended Mode, pin CP0 is used for receiving serial data, pin CP1 for transmitting serial data, and pin CP2 enables an external transceiver. Data is communicated using Differential Manchester encoding. In Special Purpose Mode, pin CP0 is used for receiving serial data, pin CP1 for transmitting serial data, pin CP2 transmits a bit clock, and pin CP4 transmits a frame clock for use by an external intelligent transceiver.
