1 / 230 page  HOLT INTEGRATED CIRCUITS www.holtic.com 1 October, 2015 MAMBATM: HI-6137 3.3V BC / RT MIL-STD-1553 / MIL-STD-1760 Compact Multi-Terminal Device with SPI Host Interface GENERAL DESCPIPTION The 3.3V CMOS HI-6137 device is a member of Holt’s MIL-STD-1553 MAMBATM family and provides a complete single- or multi-function interface between a host processor and MIL-STD-1553B bus. Each IC contains a Bus Controller (BC) and a Remote Terminals (RT). Any combination of the contained 1553 functions can be enabled for concurrent operation. The enabled terminals communicate with the MIL-STD-1553 buses through a shared on-chip dual bus transceiver and external transformers. The user allocates 16K bytes of on-chip static RAM between devices to suit application requirements. The HI-6137 communicates with the host via a 40 MHz 4-wire serial peripheral interface (SPI). Programmable interrupts provide terminal status to the host processor. Circular data buffers in RAM have interrupts for rollover and programmable “level attained”. The HI-6137 can be configured for automatic self- initialization after reset. A dedicated SPI port reads data from an external serial EEPROM to fully configure registers and RAM and optionally start execution for any of the terminal devices. FEATURES • Concurrent multi-terminal operation for BC and/or RT MIL-STD-1553B functions. • 8K x 17-bit words internal static RAM with parity • Autonomous terminal operation requires minimal host intervention. • 40 MHz SPI Host Interface. • MIL-STD-1760 option sets Busy bit in Status Word response during initialization. • World’s smallest MIL-STD-1553 terminal, QFN package measures just 6mm x 6mm. • Fully programmable Bus Controller with 28 op code instruction set. • Independent 16-bit time tag counters and clock sources for all modes. The Bus Controller also has 32- and 48-bit time count options. • 64-Word Interrupt Log Buffer queues the most recent 32 interrupts. Hardware-assisted interrupt decoding quickly identifies interrupt sources. • Built-in self-test for protocol logic, digital signal paths and internal RAM. • Optional self-initialization at reset uses external serial EEPROM. • ±8kV ESD Protection (HBM, all pins). • Two temperature ranges: -40 oC to +85oC, or -55 oC to +125oC with optional burn-in. • RoHS compliant and Tin / Lead options available.
