The HI-3588 is a silicon gate CMOS device from Holt Integrated Circuits for interfacing a Serial Peripheral Interface (SPI) enabled microcontroller to an ARINC 429 serial bus. The device provides one receiver with user-programmable label recognition for any combination of 256 possible labels, a 32 by 32 Receive FIFO and an analog line receiver. Receive FIFO status can be monitored using the programmable external interrupt pin, or by polling the HI-3588 Status Register. Other features include the ability to switch the bit-signifiance of ARINC 429 labels. The ARINC input pins are available with different input resis- tance values to provide flexibility when adding external lightning protection circuitry. The Serial Peripheral Interface minimizes the number of host interface signals allowing for a small footprint device which can be interfaced to a wide variety of industry- standard microcontrollers supporting SPI. Alternatively, the SPI signals may be controlled using just four general purpose I/O port pins from a microcontroller or custom FPGA. The SPI and all control signals are CMOS and TTL compatible and support 3.3V or 5V operation. The HI-3588 checks received data against ARINC 429 electrical, timing and protocol requirements. ARINC 429 databus timing comes from a 1 MHz clock input, or an internal counter can derive it from higher clock frequencies having certain fixed values, possibly the external host processor clock.
