Micro-ACE, Micro-ACE TE
and PCI Micro-ACE TE
MODEL: BU-6474XB/BU-6484XB/6486XB/6584XB/6586XB/61740B3/61840B3/61860B3
DESCRIPTION
The Micro-ACE, Micro-ACE TE and PCI Micro-ACE TE are the world's smallest extended temperature
range MIL-STD-1553 terminals. With a BGA package body of 0.64in, the Micro-ACE TE and PCI
Micro-ACE TE are ideal for extended temperature range applications where PC board space is at a
premium. The Micro-ACE TE and PCI Micro-ACE TE can be powered entirely by 3.3 volts, or they can
be ordered with 5V transceivers for mixed 3.3V/5V operation.
The Micro-ACE version is available in a 128-ball BGA package, rated for -40°C to +85°C operation.
The Micro-ACE TE version is rated for -40°C to +100°C operation.
The Micro-ACE, Micro-ACE TE and PCI Micro-ACE TE are fully software and architecturally compati-
ble with DDC's Enhanced Mini-ACE and PCI Enhanced Mini-ACE series of devices. They integrate
dual transceivers, protocol engine and up to 64K words of internal RAM. The PCI Micro-ACE TE
makes it simple to connect to 32 Bit / 33 MHz PCI buses while the Micro-ACE TE's flexible generic
processor interface allows direct connection with little or no glue logic to a variety of 8, 16 and
32-bit processors.
Advanced architecture is the key to the Micro-ACE series’ high performance. Advanced bus con-
troller architecture gives the Micro-ACE, Micro-ACE TE, and PCI Micro-ACE TE a high degree of flexi-
bility and autonomy. This creates advantages in a number of areas: improving message scheduling
control, minimizing host overhead for asynchronous message insertion, facilitating bulk data trans-
fers and double buffering, message retry and bus switching strategies, and data logging and fault
reporting. In addition, its remote terminal architecture provides flexibility in meeting all common MIL-
STD-1553 protocols. RT data buffering and interrupt options offer robust support for synchronous and
asynchronous messaging, ensure data sample consistency, and support bulk data transfers.
