MA3690/1/3

1553B Bus Controller/Remote Terminal

Replaces June 1999 version, DS3587-4.0

DS3587-5.0 January 2000

The MA3690/1 chip set has three modes of operation:

remote terminal, bus controller, and passive monitor It has a

dual bus capability, requires minimum support hardware /

software and is implemented on a radiation hard, CMOS/SOS

process. For applications requiring access to Terminal Flag, a

48-Pin DIL MA3693 is available as an alternative to the

MA3690.

As a remote terminal, the MA3690/1 is fully compatible with

Mil-Std-1553B. The chip set obtained SEAFAC approval in

December 1987. All options and mode commands specified by

the Mil Std are implemented Full and meaningful use is made

of status word bits and a comprehensive bit word is provided.

A unique mechanism has been incorporated that allows

the subsystem to declare illegal commands legal, and vice

versa, before the chip set services the command. It should be

noted that use of this mechanism is optional and that the

system defaults to normal operation if the option is not

required. The chip set is easily interfaced to subsystem

memory and is sufficiently flexible to ensure compatibility with

a wide range of microprocessors.

FEATURES

■ Radiation Hard to 1MRads (Si)

■ High SEU Immunity, Latch-Up Free

■ CMOS-SOS Technology

■ All Inputs and Outputs Fully TTL or CMOS Compatible

■ Military Temperature Range -55 to +125°C

■ Dual Bus Capability

■ Minimal Subsystem Interface

■ Powerful Bus Control Facility

■ Complete Remote Terminal Protocol

■ SEAFAC Approved

SIGNAL DESCRIPTIONS

All signals are TTL compatible unless stated otherwise. An

‘N’ at the end of the signal name denotes an active low signal.

As a bus controller the MA3690/1 has the ability to initiate

all types of 1553B transfer on either of the two buses An

instruction word is set up by the subsystem, prior to

transmission, which contains details of transfer type and bus

selection. Four bits of the instruction word have been used to

specify the conditions under which the chip set will generate a

subsystem interrupt. The most significant bits of the instruction

word have been used to specify the conditions under which the

chip set will perform an automatic retry and the number of

retries to be carried out (max. 3). At the end of each instruction

execution cycle, the chip set writes a report word into the

subsystem memory; the contents of which give the subsystem

an indication of the degree of success of the transfer.

The bus controller may be used in either of two

configurations, i.e. single shot or table driven.

BUS INTERFACE LINES

In the single shot configuration, the controller is under

direct control from the subsystem (processor). In table driven

configuration, the controller is given greater autonomy to

execute a table of instructions held in either ROM or RAM.

As a passive monitor, the chip set will monitor all bus

activity and pass any associated information to the subsystem.

As the name implies, in this mode of operation, the chip set is

truly passive and will not reply to command instructions.

PDIN0

Input

Positive threshold exceeded on bus 0.

NDIN0

Input

Negative threshold exceeded on bus 0.

TXEN0N

Output

Transmit enable for driver on bus 0.

PDOUT0N

Output

Positive Manchester data for driver on bus 0.
