MAMBA^TM: HI-6138
3.3V BC / MT / RT MIL-STD-1553 / MIL-STD-1760
Compact Multi-Terminal Device with SPI Host Interface
GENERAL DESCRIPTION
The 3.3V CMOS HI-6138 device is a member of Holt’s
MIL-STD-1553 MAMBA^TM 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), a Bus Monitor Terminal (MT)
and a Remote Terminal (RT). Any combination of the
contained 1553 functions can be enabed 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-6138 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”.
• 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 +85^oC, or
-55^oC to +125^oC with optional burn-in.
• RoHS compliant and Tin / Lead options available.
PIN CONFIGURATION (TOP)
The HI-6138 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
subset of one to three terminal devices.
FEATURES
• Concurrent multi-terminal operation for one to
three MIL-STD-1553B functions: BC, MT and/or
RT.
• 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.
• Simple Monitor Terminal (SMT) Mode records
commands and data separately, with 16-bit or 48-
bit time tagging.
• Independent 16-bit time tag counters and clock
sources for all modes. The Bus Controller and
Monitor also have 32- and 48-bit time count
options, respectively.
