HI-35850PQM
SKU: HI-35850PQM
HI-3585 Series ARINC 429 Protocol IC with SPI Interface
The HI-35850 from Holt Integrated Circuits is a silicon gate CMOS device for interfacing a Serial Peripheral Interface (SPI) enabled microcontroller to the ARINC 429 serial bus.?It is a drop-in replacement for Holt?s popular HI-3585, with a much improved SPI of 12 MHz. In addition, a new SPI Opcode (0x09) has been added to read multiple messages from the receive FIFO. This greatly improves host efficiency over the previous device.
