描述 Description

The ST-BUS Parallel Access Circuit (STPA) provides a simple interface between Mitel’s ST-BUS and

parallel system environments.

特性 Features

• High speed parallel access to the serial ST-BUS

• Parallel bus optimized for 68000µP (mode 1)

• Fast dual-port RAM access (mode 2) Access time: 120 nsec

• Parallel bus controller (mode 3) - no external controller required

• Flexible interrupt capabilities - two independent/programmable interrupt sources with auto-vectoring

• Selectable 24 and 32 channel operation

• Programmable loop-around modes

• Low power CMOS technology

Applications

• Parallel control/data access to T1/CEPT digital trunk interfaces

• Digital signal processor interface to ST-BUS

• Computer to Digital PABX link

• Voice store and forward systems

• Interprocessor communications
