DDC's MIL-STD-1553 terminal IC and pin, as well as software drop-in compatible IC.
Holt has announced a MIL-STD-1553 terminal that is compatible with many DDC MIL-STD-1553 terminals in both pin configuration and software register levels. All families provide a complete shape, fit, and functional alternative that allows users to drop in to existing 1553 designs without changing existing board layouts or software.
The world's smallest MIL-STD-1553 terminal IC with a transformer integrated into a thin 15×15×4.4mm package.
The HI-2130 is a product that combines the functionality of Holt's HI-6130 16-bit parallel bus interface and HI-6131 SPI device, integrating MIL-STD-1553 protocol logic, dual transceivers, and dual transformers into a single compact package. The slim 15×15×4.4mm HI-2130LBxx is one of the world's smallest single-package 1553 terminals with integrated transformers, making it ideal for use in applications such as switched mezzanine cards (XMC) or PCI mezzanine card (PMC) assemblies. The BGA package is available in both RoHS compliant and Sn/Pb options, providing customers with a solution for Sn/Pb assemblies without the need for expensive re-balling.
The MAMBA series features a 6mm x 6mm MIL-STD-1553 terminal (SPI interface).
The MAMBA series consists of 3.3V CMOS devices that provide a host processor and MIL-STD-1553B bus interface. Each IC includes BC, MT, and RT, allowing for simultaneous operation with any combination of 1553 functions. Valid terminals communicate with the MIL-STD-1553 bus via a shared on-chip dual bus transceiver and external transformers. There are four types based on functionality: - HI-6138: BC, MT, RT - HI-6137: BC, RT - HI-6136: MT, RT - HI-6135: RT Users can allocate 16KByte (8K×17Bit words) of on-chip SRAM between devices according to application requirements. The HI-613x communicates with the host via a 40MHz 4-wire SPI. Programmable interrupts provide terminal status to the host processor.
HI-35930/31/32/33 is a CMOS device for directly connecting SPI-compatible microcontrollers to the ARINC 429 bus.
The HI-35930 from Holt is a CMOS integrated circuit designed to connect SPI-compatible microcontrollers to the ARINC 429 serial bus. This device features two receivers, each with user-programmable label recognition for any combination of 256 possible labels, a 32×32 receive FIFO, three priority label quick access double buffer registers, and an analog line receiver. Both line receivers meet the lightning protection requirements of RTCA/DO-160G, Section 22, Level 3. The independent transmitter includes a 32×32 transmit FIFO and an integrated line driver. The line driver operates on a single 3.3V power supply and includes an on-chip DC/DC converter that generates the bipolar ARINC 429 differential voltage levels necessary to directly drive the ARINC 429 bus. The status of the transmit and receive FIFOs and the priority label buffer can be monitored using a programmable external interrupt pin or by polling the status register.
