MAMBATM: HI-6135
3.3V MIL-STD-1553 / MIL-STD-1760
Compact Remote Terminal with SPI Host Interface
GENERAL DESCRIPTION
PIN CONFIGURATION (TOP)
The 3.3V CMOS HI-6135 device is a member of
Holt’s 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 “level attained”.
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.
• World’s 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.

2. FEATURE OVERVIEW
HI-6135
2.1. Remote Terminal Operation
The RT is software compatible with Holt’s popular HI-6130/31 Remote Terminal. The Remote Terminal operates with
a dedicated 8K x 17-bit RAM with automatic parity check. RAM buffer options include single, double and 2 circular
buffer choices.
2.2. Interrupts
Host interrupts can originate from device hardware or any of the enabled terminal devices (up to 4 devices). A circular
64-word Interrupt Log Buffer retains interrupt information from the last 32 interrupts, while the hardware maintains a
count of occurring interrupts since the previous host buffer service.
Hardware-assisted interrupt decoding provides quick identification of the interrupt source. When a hardware interrupt
occurs (e.g., Bus A Loopback Failure), a Pending Hardware Interrupt register bit explicitly identifies the interrupt
source.
2.3. Reset and Initialization
After hardware Master Reset, there are two initialization methods: host initialization or self-initialization from external
serial EEPROM. For host initialization, the host processor uses the 4-wire SPI to load registers and initialize tables,
data buffers, etc. in internal static RAM. For self-initialization, the device uses setup information contained within an
external serial EEPROM. A dedicated 4-wire SPI port reads data from the serial EEPROM and writes it to registers and
RAM. Error checking is performed, looking for data mismatch or an EEPROM checksum error.
