HI-6138 Overview

40 MHz SPI Host Interface

MAMBA
TM
: HI-6138
3.3V BC / MT / RT MIL-STD-1553 / MIL-STD-1760
September, 2015
Compact Multi-Terminal Device with SPI Host Interface
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).
o
GENERAL DESCPIPTION
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 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-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”.
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.
Two temperature ranges: -40 C to +85 C, or
o
o
-55 C to +125 C with optional burn-in.
RoHS compliant and Tin / Lead options available.

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.

Regarding the issue of timer generating PWM, P2.1/P2.2 output the same waveform
P2.1 and P2.2 are both TA1.1, which is determined by CCR1, so the output waveforms of the two pins are the same, right? But, I want them to have opposite polarities, can I? I thought about it for a lo...
