PRELIMINARY INFORMATION

DS3577-3.4

MA2909/11

RADIATION HARD MICROPROGRAM SEQUENCER

The MA2909/11 Microprogram Sequencer is fully

FEATURES

compatible with the industry standard 2909A and 2911A

components, and forms part of the GPS 2900 Series of

devices. The series offers a building block approach to

microcomputer and controller design, with each device in the

range being expandable to permit efficient emulation of any

microcode machine.

The devices have tristate outputs and have an internal

address register, with all internal registers changing state on

LOW to HIGH clock transition.

I Fully Compatible with Industry Standard 2909A and

2911A Components

I Radiation Hard CMOS SOS Technology

I High SEU Immunity

I High Speed / Low Power

I Fully TTL Compatible

The 4-bit slice can cascade to any number of microwords.

Branch input for N-way branches is supported. Additional

features include:

I 4-bit cascadable microprogram counter.

I 4 x 4 file with stack counter supporting nesting

microsubroutines.

I Zero input for returning to the zero microcode word.

I Individual OR input for each bit for branching to higher

microinstructions (2909 only).

The 2909 is a 4-bit wide address controller intended for

sequencing through a series of microinstructions contained in

a ROM or PROM. Two 2909s may be interconnected to

generate an 8-bit address (256 words), and three may be used

to generate a 12-bit address (4K words).

The 2909 can select an address from any of four sources:

1) A set of external direct inputs (D);

2) External data from the R inputs, stored in an internal

3) A four-word push/pop stack; or

4) A program counter register (which usually contains the

last address plus one).

The push/pop stack includes certain control lines so that it

can efficiently execute nested subroutine linkages. Each of the

four outputs can be OR’ed with an external input for conditional

skip or branch instructions, and a separate line forces the

outputs to all zeroes. The outputs are three-state.

The 2911 is an identical circuit to the 2909 except the four

OR inputs are removed and the D and R inputs are tied

together.
