The ARINC 429 unit of transmission is a fixed-length 32-bit frame, which the standard refers to as a 'word'. The bits within an ARINC 429 word are serially identified from Bit Number 1 to Bit Number 32 [4] or simply Bit 1 to Bit 32. The fields and data structures of the ARINC 429 word are defined in terms of this numbering.
ARINC 429 operates in such a way that its single transmitter communicates in a point-to-point connection, thus requiring a significant amount of wiring which amounts to added weight. Another standard, ARINC 629 , introduced by Boeing for the 777 provided increased data speeds of up to 2 Mbit/s and allowing a maximum of 120 data terminals.
The ARINC 615 standard covers "data loading" over ARINC 429. ARINC 615A is a standard that covers a "data loading" protocol which can be used over various bus types such as Ethernet, CAN, and ARINC 664. ARINC 618 is a standard that covers a data transmission protocol called "Character Oriented Protocol". ARINC 619 is a standard that covers a ...
Most civilian aircraft use one of 3 serial buses: the Commercial Standard Digital Bus (CSDB), [1] ARINC 429, or AS-15531. The Commercial Standard Digital Bus is a two-wire asynchronous broadcast data transmission bus. Data is transmitted over an interconnecting cable by devices that comply with Electronic Industries Association (EIA) RS-422A.
Neither actually; ARINC 429 is specified independent of microcontroller architecture. We have 8-bit processors here driving ARINC 429. ARINC 429 transceivers IC’s were based on 32-bit shift registers; and IIRC the standard predates widespread use of 16-bit processors. IveGoneAway 22:43, 28 October 2013 (UTC)
Output interfaces typically are ARINC 429, Gillham or even IEEE 1394 (Firewire). The data provided may be true airspeed, pressure altitude, density altitude and Outside Air Temperature (OAT), but with no involvement in aircraft attitude or heading, as there are no gyroscopes or accelerometers fitted internally.

MIL-STD-1553 is a military standard published by the United States Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus.
