MA2910

RADIATION HARD MICROPROGRAM CONTROLLER

The industry standard MA2910 Microprogram Controller

forms part of the MA2900 family of devices.

Offering a building block approach to microcomputer and

controller design, each device in the range is expandable

permitting efficient emulation of any microcode-controlled

machine. The family has been designed for operation in

severe environments such as space, and is qualified to the

highest levels of reliability.

The MA2910 Micro-program Controller is an address

sequencer intended for sequence control of microinstructions

stored in microprogram memory in high speed micro-

processor applications.

All internal elements are full 12 bits wide and address up to

4096 words with one chip. The device has an integral settable

12 bit internal loop counter for repeating instructions and

counting loop iterations.

The MA2910 has four address sources which allow

Microprogram Address to be selected from the microgram

counter, branch address bus, 9 level push/pop stack, or

internal holding register.

The MA2910 supports 100ns cycle times and has an

integral decoder function to enable external devices onto

branch address bus which eliminates the requirement for an

external decoder.
