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.
The HI‑3588 is a silicon‑gate CMOS device that connects a microcontroller’s Serial Peripheral Interface (SPI) to an ARINC‑429 serial bus. It provides one receiver with user‑programmable label recognition for up to 256 labels, a 32 × 32 receive FIFO, and an on‑chip analog line receiver. The SPI and all control signals are CMOS/TTL compatible and support 3.3 V or 5 V operation.
The device includes two sets of line‑receiver pins (RINA/B and RINA/B‑40); the latter require external 40 kΩ series resistors for lightning‑protection applications. Electrical specifications cover a supply range of 3.3 V–5 V, industrial temperature operation from –40 °C to +85 °C, and absolute maximum ratings up to 7 V on VDD. Pin‑out is provided for a 44‑pin QFN or PQFP package.
