HI-3584 September 2006 Enhanced ARINC 429 3.3V Serial Transmitter and Dual Receiver APPLICATIONS ! Avionics data communication ! Serial to parallel conversion ! Parallel to serial conversion GENERAL DESCRIPTION The HI-3584 from Holt Integrated Circuits is a silicon gate CMOS device for interfacing a 16-bit parallel data bus to the ARINC 429 serial bus. The HI-3584 design offers many enhancements to the industry standard HI-8282 architecture. The device provides two receivers each with label recognition, a 32 by 32 FIFO, and an analog line receiver. Up to 16 labels may be programmed for each receiver. The independent transmitter also has a 32 by 32 FIFO. The status of all three FIFOs can be monitored using the external status pins or by polling the HI-3584’s status register. Other new features include a programmable option of data or parity in the 32nd bit, and the ability to unscramble the 32 bit word. Also, versions are available with different values of input resistance to allow users to more easily add external lightning protection circuitry. The 16-bit parallel data bus exchanges the 32-bit ARINC data word in two steps when either loading the transmitter or interrogating the receivers. The databus and all control signals are CMOS and TTL compatible. The HI-3584 applies the ARINC protocol to the receivers and transmitter. Timing is based on a 1 Megahertz clock. Additional interface circuitry such as the Holt HI-8585 or HI-8586 is required to translate the transmitter’s 3.3 volt logic outputs to ARINC 429 drive levels.

The control register bits CR0 - CR15 are loaded from BD00 - BD15 when CWSTR is pulsed low. The control register contents are output on the databus when SEL = 1 and RSR is pulsed low. Each bit of the control register has the following function: CR Bit CR0 STATUS REGISTER The HI-3584 contains a 9-bit status register which can be interrogated to determine the status of the ARINC receivers, data FIFOs and transmitter. The contents of the status register are output on BD00 - BD08 when the RSR pin is taken low and SEL = 0. Unused bits are output as zeros. The following table defines the status register bits.

ARINC 429 DATA FORMAT Control register bit CR15 is used to control how individual bits in the received or transmitted ARINC word are mapped to the HI-3584 data bus during data read or write operations. The following table describes this mapping: BYTE 1 DATA BUS ARINC BIT CR15=0 ARINC BIT CR15=1 BD BD BD BD BD BD BD BD BD BD BD BD BD BD BD BD 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 13 12 11 10 9 31 30 32 1 2 3 4 5 6 7 8 The HI-3584 guarantees recognition of these levels with a common mode Voltage with respect to GND less than ±4V for the worst case condition (3.0V supply and 13V signal level). The tolerances in the design guarantee detection of the above levels, so the actual acceptance ranges are slightly larger. If the ARINC signal is out of the actual acceptance ranges, including the nulls, the chip rejects the data. RECEIVER LOGIC OPERATION Figure 2 shows a block diagram of the logic section of each receiver. BIT TIMING The ARINC 429 specification contains the following timing specification for the received data: HIGH SPEED LOW SPEED 100K BPS ± 1% 12K -14.5K BPS BIT RATE 10 ± 5 µsec PULSE RISE TIME 1.5 ± 0.5 µsec 10 ± 5 µsec PULSE FALL TIME 1.5 ± 0.5 µsec 5 µsec ± 5% 34.5 to 41.7 µsec PULSE WIDTH The HI-3584 accepts signals that meet these specifications and rejects signals outside the tolerances. The way the logic operation achieves this is described below: 1. Key to the performance of the timing checking logic is an accurate 1MHz clock source. Less than 0.1% error is recommended. 2. The sampling shift registers are 10 bits long and must show three consecutive Ones, Zeros or Nulls to be considered valid data. Additionally, for data bits, the One or Zero in the upper bits of the sampling shift registers must be followed by a Null in the lower bits within the data bit time. For a Null in the word gap, three consecutive Nulls must be found in both the upper and lower bits of the sampling shift register. In this manner the minimum pulse width is guaranteed.

The ARINC 429 specification requires the following detection levels: STATE ONE NULL ZERO DIFFERENTIAL VOLTAGE +6.5 Volts to +13 Volts +2.5 Volts to -2.5 Volts -6.5 Volts to -13 Volts Parity Label Label Label Label Label Label Label Label SDI SDI Label 1 SDI SDI 3. Each data bit must follow its predecessor by not less than 8 samples and no more than 12 samples. In this manner the bit rate is checked. With exactly 1MHz input clock frequency, the acceptable data bit rates are as follows: HIGH SPEED ONES VDD RIN1A OR RIN2A GND DIFFERENTIAL AMPLIFIERS COMPARATORS LOW SPEED 10.4K BPS 15.6K BPS DATA BIT RATE MIN DATA BIT RATE MAX 83K BPS 125K BPS NULL VDD RIN1B OR RIN2B GND ZEROES 4. The Word Gap timer samples the Null shift register every 10 input clocks (80 for low speed) after the last data bit of a valid reception. If the Null is present, the Word Gap counter is incremented. A count of 3 will enable the next reception. FIGURE 1. ARINC RECEIVER INPUT HOLT INTEGRATED CIRCUITS 4 HI-3584 FUNCTIONAL DESCRIPTION (cont.) RECEIVER PARITY The receiver parity circuit counts Ones received, including the parity bit. If the result is odd, then "0" will appear in the 32nd bit. CR2(3) ARINC word CR6(9) ARINC word matches bits 9,10 label match CR7,8 (10,11) 0 1 1 0 0 1 1 1 1 X No Yes X X Yes No No Yes 0 0 0 1 1 1 1 1 1 X X X No Yes No Yes No Yes FIFO RETRIEVING DATA Once 32 valid bits are recognized, the receiver logic generates an End of Sequence (EOS). Depending upon the state of control register bits CR2-CR11, the received ARINC 32-bit word is then checked for correct decoding and label matching before being loaded into the 32 x 32 receive FIFO. ARINC words which do not meet the necessary 9th and 10th ARINC bit or label matching are ignored and are not loaded into the receive FIFO. The following table describes this operation.

RECEIVER BLOCK DIAGRAM HOLT INTEGRATED CIRCUITS 5 HI-3584 FUNCTIONAL DESCRIPTION (cont.) Once a valid ARINC word is loaded into the FIFO, then EOS clocks the data ready flag flip flop to a "1", D/R1 or D/R2 (or both) will go low. The data flag for a receiver will remain low until both ARINC bytes from that receiver are retrieved and the FIFO is empty. This is accomplished by first activating EN with SEL, the byte selector, low to retrieve the first byte and then activating EN with SEL high to retrieve the second byte. EN1 retrieves data from receiver 1 and EN2 retrieves data from receiver 2. Up to 32 ARINC words may be loaded into each receiver’s FIFO. The FF1 (FF2) pin will go low when the receiver 1 (2) FIFO is full. Failure to retrieve data from a full FIFO will cause the next valid ARINC word received to overwrite the existing data in FIFO location 32. A FIFO half full flag HF1 (HF2) goes low if the FIFO contains 16 or more received ARINC words. The HF1 (HF2) pin is intended to act as an interrupt flag to the system’s external microprocessor, allowing a 16 word data retrieval routine to be performed, without the user needing to continually poll the HI3584’s status register bits. READING LABELS After the write that changes CR1 from 0 to 1, the next 16 data reads of the selected receiver (EN taken low) are labels. EN1 is used to read labels for receiver 1, and EN2 to read labels for receiver 2. Label data is presented on BD00 - BD07. When writing to, or reading from the label memory, SEL must be a one, all 16 locations should be accessed, and CR1 must be written to zero before returning to normal operation. Label recognition must be disabled (CR2/3=0) during the label read sequence. TRANSMITTER FIFO OPERATION The FIFO is loaded sequentially by first pulsing PL1 to load byte 1 and then PL2 to load byte 2. The control logic automatically loads the 31 bit word (or 32 bit word if CR4=0) in the next available position of the FIFO. If TX/R, the transmitter ready flag is high (FIFO empty), then up to 32 words, each 31 or 32 bits long, may be loaded. If TX/R is low, then only the available positions may be loaded. If all 32 positions are full, the FFT flag is asserted and the FIFO ignores further attempts to load data. A transmitter FIFO half-full flag HFT is provided. When the transmit FIFO contains less than 16 words, HFT is high, indicating to the system microprocessor that a 16 ARINC word block write sequence can be initiated. In normal operation (CR4=1), the 32nd bit transmitted is a parity bit. Odd or even parity is selected by programming control register bit CR12 to a zero or one. If CR4 is programmed to a 0, then all 32-bits of data loaded into the transmitter FIFO are treated as data and are transmitted. LABEL RECOGNITION The chip compares the incoming label to the stored labels if label recognition is enabled. If a match is found, the data is processed. If a match is not found, no indicators of receiving ARINC data are presented. Note that 00(Hex) is treated in the same way as any other label value. Label bit significance is not changed by the status of control register bit CR15. Label bits BD00-BD07 are always compared to received ARINC bits 1 -8 respectively. LOADING LABELS After a write that takes CR1 from 0 to 1, the next 16 writes of data (PL pulsed low) load label data into each location of the label memory from the BD00 - BD07 pins. The PL1 pin is used to write label data for receiver 1 and PL2 for receiver 2. Note that ARINC word reception is suspended during the label memory write sequence.

TRANSMITTER BLOCK DIAGRAM HOLT INTEGRATED CIRCUITS 6 HI-3584 FUNCTIONAL DESCRIPTION (cont.) DATA TRANSMISSION When ENTX goes high, enabling transmission, the FIFO positions are incremented with the top register loading into the data transmission shift register. Within 2.5 data clocks the first data bit appears at 429DO and 429DO. The 31 or 32 bits in the data transmission shift register are presented sequentially to the outputs in the ARINC 429 format with the following timing: HIGH SPEED 10 Clocks 5 Clocks 5 Clocks 40 Clocks LOW SPEED 80 Clocks 40 Clocks 40 Clocks 320 Clocks REPEATER OPERATION Repeater mode of operation allows a data word that has been received by the HI-3584 to be placed directly into the transmitter FIFO. Repeater operation is similar to normal receiver operation. In normal operation, either byte of a received data word may be read from the receiver latches first by use of SEL input. During repeater operation however, the lower byte of the data word must be read first. This is necessary because, as the data is being read, it is also being loaded into transmitter FIFO which is always loaded with the lower byte of the data word first. Signal flow for repeater operation is shown in the Timing Diagrams section. ARINC DATA BIT TIME DATA BIT TIME NULL BIT TIME WORD GAP TIME HI-3584-10 The HI-3584-10 option is similar to the HI-3584 with the exception that it allows an external 10 Kohm resistor to be added in series with each ARINC input without affecting the ARINC input thresholds. This option is especially useful in applications where lightning protection circuitry is also required. Each side of the ARINC bus must be connected through a 10 Kohm series resistor in order for the chip to detect the correct ARINC levels. The typical 10 volt differential signal is translated and input to a window comparator and latch. The comparator levels are set so that with the external 10 Kohm resistors, they are just below the standard 6.5 volt minimum ARINC data threshold and just above the standard 2.5 volt maximum ARINC null threshold. Please refer to the Holt AN-300 Application Note for additional information and recommendations on lightning protection of Holt line drivers and line receivers. The word counter detects when all loaded positions have been transmitted and sets the transmitter ready flag, TX/R, high. TRANSMITTER PARITY The parity generator counts the Ones in the 31-bit word. If control register bit CR12 is set low, the 32nd bit transmitted will make parity odd. If the control bit is, high the parity is even. Setting CR4 to a Zero bypasses the parity generator, and allows 32 bits of data to be transmitted. SELF TEST If control register bit CR5 is set low, the transmitter serial output data are internally connected to each of the two receivers, bypassing the analog interface circuitry. Data is passed unmodified to receiver 1 and inverted to receiver 2. The serial data from the transmitter is always present on the 429DO and 429DO outputs regardless of the state of CR5. HIGH SPEED OPERATION The HI-3584 may be operated at clock frequencies beyond that required for ARINC compliant operation. For operation at Master Clock (CLK) frequencies up to 5MHz, please contact Holt applications engineering. SYSTEM OPERATION The two receivers are independent of the transmitter. Therefore, control of data exchanges is strictly at the option of the user. The only restrictions are: 1. The received data will be overwritten if the receiver FIFO is full and at least one location is not retrieved before the next complete ARINC word is received. 2. The transmitter FIFO can store 32 words maximum and ignores attempts to load additional data if full. MASTER RESET (MR) On a Master Reset data transmission and reception are immediately terminated, all three FIFOs are cleared as are the FIFO flags at the device pins and in the Status Register. The Control Register is not affected by a Master Reset.
