HI-1575

MIL-STD-1553 3.3V Dual Transceivers

with Integrated Encoder / Decoders

February 2006

DESCRIPTION

PIN CONFIGURATIONS

The HI-1575 is a low power CMOS dual transceiver with

on-chip Manchester II Encoder and dual Decoder

designed to meet the requirements of the MIL-STD-1553

specification. The part acts as a "Smart Transceiver",

allowing users to transmit and receive properly encoded

MIL-STD-1553 Command and Data words between a

16-bit host processor and dual MIL-STD-1553 data

buses.

A single write cycle is used to transfer a word to the

HI-1575, which encodes the data, adds the selected Sync

and Parity bits, and transmits the word on the chosen

MIL-STD-1553 data bus. Complete MIL-STD-1553

messages may be transmitted by executing multiple write

cycles to the device.

40 Pin Plastic 6mm x 6mm

Chip-scale package

Activity on both MIL-STD-1553 data buses is continuously

monitored. When the HI-1575 detects a properly encoded

word, a hardware interrupt is generated and the

information is decoded and stored in one of two internal

registers, which may then be read by the host processor.

Bits in the internal Status & Mode Register indicate on

which bus the word was received and whether the word

had a Data or Command Sync.
