HI-6010 January 2006 ARINC 429 TRANSMITTER/RECEIVER FOR 8 BIT BUS FEATURES ! ! ! ! ! ! ! ARINC 429 protocol controller with interface to an 8 bit bus Automatic label recognition option 8 bit or 32 bit buffering option Self test and parity options CMOS / TTL logic pins Plastic and ceramic package options - surface mount or DIP Military processing available GENERAL DESCRIPTION The HI-6010 is a CMOS integrated circuit designed to interface the avionics data bus standard ARINC 429 to an 8 bit port. It contains one receiver and one transmitter. They operate independently except for the self test option and the parity option. The receiver demands that the incoming data meet the standard protocol and the transmitter outputs a standard protocol stream. The HI-6010 provides flexible options for interfacing to the user system. The controlling processor can operate both the receiver and transmitter either by using hard wired flags and gates at the pins or by using software reads and writes of the Status Register and Control Register or a combination thereof. The chip is programmable to operate with single 8 bit bytes requiring "on the fly transmitter loading and receiver downloading" or to operate in 32 bit "extended buffer" mode. In addition there is an option to use automatic label recognition after loading 8 possible labels for comparison. Parity and self test are also software programmable. Master Reset is activated only by taking the MR pin high. Two clock inputs allow independent selection of the data rates of the transmitter and receiver. Each must be 4X the desired ARINC 429 frequency. Error flags are generated for transmitter underwrites and for receiver data framing miscues, parity errors, and buffer overwrites. The HI-6010 is a 5 volt chip that will require data translation from and to the ARINC bus. The HI-8482 and HI-8588 line receivers are available for the receiver side and the HI-318X and HI-858X line drivers are available for the transmitter side.

USING THE RECEIVER The receiver logic is independent of the transmitter except in the following ways: 1. Self Test 2. Parity Option In self test, the transmitter outputs route to the receiver inputs internally ignoring the external inputs. Also in self test, the external receiver clock is replaced with the transmitter clock. The parity option affects both the receiver and transmitter. Either both are operational or neither. goes high for any one of three receiver errors. The status register will show which of the three errors occurred: Status Register Bit SR3 SR4 SR5 Error Received a parity error Data Overwritten Receiving sequence error The possible Receiver sequence errors are: 1. RXD0 and RXD1 simultaneously a one. 2. Less than 32 bits before 3 nulls. 3. More than 32 bits. There are no errors flagged for labels received that don't match stored labels when in the label recognition mode. Errors are cleared by MR or by reading the Status Register. HARDWARE CONTROL OF THE RECEIVER PIN 2 - WEF WEF is an error indicator. It goes high for a transmitter "underwrite" (failure to keep up with byte loading) and pin 2 PIN 5 - HFS and the CONTROL REGISTER This pin, along with the control register, sets up the functioning (e.g. modes) of the chip. If HFS is low, the HOLT INTEGRATED CIRCUITS 2 HI-6010 USING THE RECEIVER (cont.) receiver is not programmable to the 32 bit "extended buffer" mode nor to the label recognition mode. Affecting the receiver: PIN 14 - RXD0 and PIN 16 - RXD1 These pins must be 5 volt logic levels. There must be a translator between the ARINC bus and these inputs. Typically a receiver chip, such as the HI-8482 or HI-8588 is inserted between the ARINC bus and the logic chips. RXD0 is looking for a high level for zero inputs and RXD1 is looking for a high level for one inputs. When both inputs are low this is referred to as the Null state. CONTROL PROGRAM PIN 5 BIT NAME VALUE VALUE OPERATION CR1 X 0 1 0 1 1 No action No action Next 8 data read cycles will read stored labels. One time only sequence on each transiton of CR1 to a 1. Receiver is disabled Receiver is enabled RXRDY goes high normally Blocks RXRDY for one ARINC word Self test disabled Self test enabled No parity errors enabled and 32nd bit is data Parity error flag enabled 32 bit "extended mode" enabled and parity enabled. 8 bit "one byte at a time" mode and parity enabled. Label recognition not programmable Label recognition disabled Label recognition enabled SOFTWARE CONTROL OF THE RECEIVER By writing to the Control Register and reading the Status Register the controlling processor can operate the receiver without hardware interrupts. The Control Register in combination with the wiring of pin 5 was explained above. The Status Register bits pertaining to the receiver are explained below: STATUS BIT VALUE MEANING CR2 CR3* CR4 CR5 0 1 0 1 0 1 0 1 0 1 X X X X X X 0 0 1 1 0 1 1 SR1 SR3 SR4 SR5 0 1 0 1 0 1 0 1 0 1 No receiver data Receiver data ready No parity error Parity error - Parity was even Receiver data not overwritten Receiver data was overwritten Receiver data received without framing error Framing error - Did not receive exactly 32 good bits Did not receive first byte Received first byte - Same flag as pin 13 CR7 X 0 1 SR6 * CR3 will be automatically reset to 0 after being programmed to a 1 at the completion of an ARINC word reception. This allows a software label recognition different from the automatic option available. COMMUNICATING WITH THE CONTROL AND STATUS REGISTERS Pin 27, C/D, must be high to read the status register or write the control register. Reading the status register resets errors. There is no provision to read the control register. PIN 6 - MR When MR is a 1, the control word is set to 0X10 0101 (CR7 CR0). For the receiver this sets up 8 bit mode with the receiver and parity enabled. MR also initializes the registers and logic. The first ARINC reception will only occur after a word gap. PIN 8 - RXRDY LABEL RECOGNITION OPTION Pin 5 must be high if label recognition is selected in either the 8 or 32 bit modes and all eight label buffers must be written using redundant labels, if necessary. The chip compares the incoming label to the stored labels. If a match is found, the data is processed. If a match is not found, no indicators of receiving ARINC data are presented. In 8 bit mode, this pin goes high whenever 8 bits are received without error. In 32 bit mode, this pin goes high after all 32 bits are received with no error. This flag may be inhibited for one ARINC word if CR3 is programmed to 1. This flag is also inhibited in label recognition if the incoming ARINC label does not match one of the stored 8 labels. LOADING LABELS After the write that changes CR7 from 0 to 1, the next 8 writes of data (C/D is a zero for data) will load the label registers. Labels must be loaded whenever pin 5 goes from low to high. PIN 12 - RXC This pin must have a clock applied that is 4X the desired receive frequency. PIN 13 - FCR In 8 bit mode, this pin flags the first character (byte) received. In 32 bit mode, this pin goes high for a valid 32 bit word. The pin is not affected by CR3 programming. READING LABELS After the write that changes CR1 from 0 to 1, the next 8 data reads are labels. HOLT INTEGRATED CIRCUITS 3 HI-6010 USING THE TRANSMITTER The transmitter logic is independent of the receiver except in the following ways: 1. Self Test 2. Parity Option In self test the transmitter outputs route to the receiver inputs internally and the TXD0 and TXD1 outputs are inhibited. When parity is enabled, both the receiver and transmitter are affected. Odd parity is automatically generated in the 32nd bit if this option is selected. PIN 7 - TXE Whenever a transmission begins, this pin goes low and returns high after the transmission is complete. PIN 9 - TXRDY Whenever TXRDY is a one, data may be written into the transmitter buffer. In 8 bit "one byte at a time" mode, this pin may be monitored to indicate when to write the next 8 bits. PIN 10 - TXD0 and PIN 11 - TXD1 TXD0 will go high during a transmission if the data is zero. TXD1 goes high if data is a one. When both pins are low this is referred to as the Null state. Typically an ARINC transmitter chip, such as the HI-3182, HI-3183, HI-8585 or HI-8586 is connected to these pins to translate the 5 volt levels to the proper ARINC bus levels. Data is not output when the HI-6010 is in self-test mode. HARDWARE CONTROL OF THE TRANSMITTER PIN 2 - WEF This output goes high for 1 transmitter error and 3 receiver errors. To determine which error is being flagged, read the Status Register. Reading the Status Register also clears the error flag. The transmitter will not function until the error is cleared. It can also be cleared by MR going high. The only possible transmitter error is generated when running in 8 bit mode. For the transmitter this means loading the last 3 bytes while the transmission is in progress. Failure to load a byte before the previous byte's 8th bit is transmitted will generate the error, indicated by status bit SR7 set to a 1. SOFTWARE CONTROL OF THE TRANSMITTER By writing into the Control Register and reading the Status Register, the controlling processor can operate the transmitter independent of the flags at the pins. Transmission can be initiated by changing CR0 from a 0 to a 1 after the transmitter buffer has been loaded. Then the Status Register may be monitored as follows: STATUS BIT SR0 SR2 SR7 VALUE 0 1 0 1 0 1 MEANING Do not load the transmitter buffer Ready to load the transmitter buffer Transmission in progress Transmitter is idle No transmission error 8 bit mode only error for underwriting data PIN 3 - CTS This pin is a hardware gate for transmissions. If the transmitter buffer is loaded and Control Register bit CR0 is a one, the only inhibit of the transmitter would be for CTS to be a one. When taken low, transmission of an ARINC word is enabled. It may be pulsed to release each transmitted word. PIN 4 - TXC The data rate of transmission is controlled by this pin. This clock must be 4X the desired date rate. PIN 5 - HFS and the CONTROL REGISTER This pin along with the Control Register sets the functioning of the chip. For the transmitter: CONTROL BIT NAME PROGRAM VALUE PIN 5 VALUE APPLICATIONS TIPS Cabling Noise The HI-6010 has TTL compatible inputs and therefore they are susceptible to noise near ground. If the data bus is passed by ribbon cable or the equivalent to the device under test, it is possible to get significant glitches on the Master Reset line. The problem will appear to be a pattern sensitive failure. One cure is simply to adequately bypass Master Reset. Another is to buffer the HI-6010 inputs near the chip. Receiver Seems Dead After Master Reset the HI-6010 receiver must see a word gap before the first ARINC data bit. Error flags must be cleared by either a Status Register Read or by a Master Reset. The operation of either the transmitter or the receiver is inhibited upon error. OPERATION Transmitter is disabled Transmitter is enabled Not in self test Self test enabled 8 bit mode + data in 32nd bit 8 bit mode + parity enabled 32 bit mode with parity enabled 8 bit mode with parity enabled CR0 CR4 CR5 0 1 0 1 0 1 0 1 X X X X 0 0 1 1 PIN 6 - MR The chip is initialized whenever this pin goes high. The Control Register is set to 0X10 0101 (CR7 - CR0). For the transmitter this sets up 8 bit mode with the transmitter enabled.
