UCM3070 Boundary Scan Module for the Keysight Utility Card

Technical Overviews

Technical Overview

1. Overview

The UCM3070 is a boundary scan controller, which is customized for integration into the Keysight Technologies, Inc. Utility Card on the Keysight Medalist i3070 Series 5 in-circuit test (ICT) system.

This controller is based on the GOEPEL SCANBOOSTER architecture and is designed as a plug-in card for usage in a free slot on the Keysight Utility Card. 

2. Hardware Features of the UCM3070

2.1 PIP Signals

The UCM3070 interface comprises the test access port (TAP) signals and further signals for extended functions and measurements. These include the parallel interface ports (PIPs), whose signals allow control of TAP-synchronous functions.

This is advantageous for flash programming. Usually, the Read-, Write- and Enable signals (e.g. WR, RD, CE, CS) are controlled through the boundary scan chain and require a complete shift cycle in order to generate an edge.

Therefore it is useful to externally route the control signals via PIP signals to the flash device to considerably accelerate flash programming. Altogether, the UCM3070 provides two groups of four bi-directional digital PIP signals each. 

2.2 Analog Signals

The UCM3070 provides two independent bi-directional analog channels. However, they can only be used alternatively to PIP signals PIP2.2 and PIP2.3. Hence you cannot use these two PIP signals. Each analog channel can be driven by a D/A converter and measured by an A/D converter. 

The D/A converter can be set to high-impedance state, so that the A/D converter is capable of measuring external voltages. The D/A converter can output voltages from 0 V to 4.096 V with an accuracy of ± 0.05 V. The A/D converter can measure voltages from 0 V to 4.096 V with a resolution of 4 mV. 

2.3 Signal Adaptation

The UCM3070 module offers some basic functions for signal adaptation. The TAP output signals TCK, TMS, TDO, and TRST can be routed through serial resistors of 15 ­, 22 ­, 33 ­ or left inactively (open). The TDI input signal is connected to a pull-down resistor of 220 ­, 330 ­, 1 k­ or to no resistor. 

Highlight of UCM3070 Features

– Two independent voltage and impedance-programmable test access ports (TAPs)

– Adjustable output voltage and input threshold of the TAP signals

– 2 x 4 parallel interface ports (PIPs) for usage as fast input / output (I/O) signals (e.g. for flash programming)

– Two analog I/Os (for measuring or driving analog voltages)

– Operation via USB2.0 high-speed interface

– Additional external power supply is not required since this is provided by the Keysight Utility Card.

– Integrated self-test functions for extended system analysis

3. Software Features of the UCM3070

Keysight’s BT-Basic in-circuit test software has implemented special commands to call an external device integrated with the Keysight Utility Card. These XD-commands build the software interface between both systems.

UCM3070 receives and executes commands via USB2.0 high speed interface. A DLL is provided which allows the UCM3070 to be controlled by the BT-Basic commands.
