Description
The HI-3593 from Holt Integrated Circuits is a CMOS integrated circuit for interfacing a Serial Peripheral Interface (SPI) enabled microcontroller to the ARINC 429 serial bus.
Features
- include a programmable option of data or parity in the 32nd bit, and the ability to switch the bit-signifiance of ARINC 429 labels. Pins are available with different input resistance and output resistance values which provides flexibility when using external lightning protection circuitry. The Serial Peripheral Interface minimizes the number of host interface signals resulting in a small footprint device that can be interfaced to a wide range of industry-standard microcontrollers supporting SPI.
