MA^M1^A7¹5⁷⁵0⁰3³

Radiation Hard MIL-STD-1750A Interrupt Unit

Replaces June 1999 version, DS3566-4.0

DS3566-5.0 January 2000

The MA17503 Interrupt Unit is a component of the MAS281

chip set. Other chips in the set include MA17501 Execution Unit

and the MA17502 Control Unit. Also available is the peripheral

MA31751 Memory Management/Block Protection Unit. The

lnterrupt Unit, in conjunction with these additional chips,

implements the full MIL-STD-1750A Instruction Set

Architecture.

BLOCK DIAGRAM

The MA17503 - consisting of the Pending Interrupt

Timer, and DMA interface - handles all interrupt fault, and DMA

interfacing, in addition to providing all three hardware timers.

The Interrupt Unit also implements 26 of the MIL-STD-1750A

specified l/O commands. Table 1 provides brief signal

definitions.

The MA17503 is offered in dual-in-line, flatpack or leadless

chip carrier packaging. Screening and packaging options are

described at the end of this document.
