Holt Integrated Circuits Inc. HI-3588PCIF

HI-3588 is an ARINC 429 receiver for avionics interface designs. It converts incoming differential bus signals into received words that a microcontroller can read through its SPI port. A programmable label-recognition function, a 32-word by 32-bit receive FIFO, and a configurable receive flag help the host filter and manage traffic. The PCIF ordering option identifies Holt's commercial-temperature 44-pin QFN version.

The LCDChip product record specifies 44-VFQFN Exposed Pad. Holt identifies HI-3588PCIF as a 44-pin plastic 7 mm × 7 mm QFN with a commercial -40°C to +85°C temperature range. Match the manufacturer's mechanical drawing, pad dimensions, exposed-pad guidance, and top-view pin orientation to the actual board footprint.

Layout checks

• Confirm the QFN pin-1 index and 7 mm × 7 mm body drawing.
• Review the exposed pad, thermal, and grounding requirements.
• Keep ARINC input routing and external resistor choices consistent with Holt's reference circuitry.

Holt's HI-3588 44-pin QFN top-view pin diagram identifies these functional connections:

Remaining positions shown as N/C in the Holt pin diagram must be handled according to the manufacturer's package and connection guidance. Do not infer pad wiring from a generic QFN photograph.

Electrical limits, input thresholds, timing, and absolute maximum ratings are conditional values; use Holt's current data sheet rather than these summary specifications for design sign-off.

A candidate replacement must match ARINC receive behavior, SPI protocol and timing, input network, supply, FIFO and label programming, temperature grade, and the exact QFN pinout and land pattern. Other HI-3588 ordering codes may differ in package or qualification. No unverified LCDChip alternative-product link is asserted here.

Holt Integrated Circuits publishes the HI-3588 family documentation and identifies HI-3588PCIF as the 44-pin plastic QFN commercial-temperature ordering option. Consult Holt's HI-3588 product page, ordering information, Rev. H data sheet, and any subsequent manufacturer notices for controlled specifications.

Confirm the full HI-3588PCIF ordering code, device marking, lot traceability, package dimensions, MSL handling, and applicable manufacturer documentation. A generic package image cannot authenticate the device or substitute for electrical and receiving inspection.

Validate the ARINC input coupling and external resistors, SPI mode and timing, ACLK source, reset sequence, power decoupling, unused pins, exposed pad, and the exact PCIF temperature and package markings against current Holt material. The registered package JPG is not available on the production website; supply and verify that asset before publishing this page.
