MAMBATM: HI-6135
3.3V MIL-STD-1553 / MIL-STD-1760
Compact Remote Terminal with SPI Host Interface
GENERAL DESCPIPTION
The 3.3V CMOS HI-6135 device is a member of
Holtâs MIL-STD-1553 MAMBATM family and provides a
complete Remote Terminal interface between a host
processor and MIL-STD-1553B bus. The terminal
communicates with the MIL-STD-1553 buses through an
on-chip dual bus transceiver and external transformers.
The user allocates 16K bytes of on-chip static RAM to
suit application requirements.
The HI-6135 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 âlevel attainedâ.
The HI-6135 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.
FEATURES
⢠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.
⢠Worldâs smallest RT solution, QFN package
measures just 6mm x 6mm.
⢠16-bit time tag counter and independent clock
sources.
⢠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: -40oC to +85oC, or
-55oC to +125oC with optional burn-in.
⢠RoHS compliant and Tin / Lead options available.
