Support Description
This chapter provides information on the following topics:
H A description of the TMS 140 microcontroller support
H Logic analyzer software compatibility
H Your system under test requirements
H Support restrictions
H How to configure the probe adapter
H How to connect to the system under test (SUT)
The TMS 140 microcontroller support disassembles data from systems that are
based on the Intel 8031, 8032, 8051 and 8052 microcontrollers. The TMS 140
supports all 8031 and 8051 core-type microcontrollers that are compatible with
Intel MCS-51. The support runs on a compatible Tektronix logic analyzer
equipped with a 68/102/136-channel module or a 96-channel module.
Refer to information on basic operations to determine how many modules and
probes your logic analyzer needs to meet the minimum channel requirements for
the TMS 140 microcontroller support.
NOTE. The 8051 and 8052 have internal RAM and ROM. Only bus activity
outside the microcontroller is disassembled. Internal activity is not present on the
bus and cannot be disassembled.
Table 1–1 shows the microcontrollers and packages from which the TMS 140
support can acquire and disassemble data.

Getting Started
To use this support efficiently, you need to have the items listed in the information on basic operations as well as the 8-Bit Embedded Controller’s Manual, Intel
Inc., 1991
Information on basic operations also contains a general description of supports.
Logic Analyzer Software Compatibility
The label on the microcontroller support floppy disk states which version of logic
analyzer software the support is compatible with.
Logic Analyzer Configuration
To use the 8031, 8032, 8051 and 8052 support, the Tektronix logic analyzer must
be equipped with either a 68/102/136-channel module, or a 96-channel module at
a minimum. The module must be equipped with enough probes to acquire clock
and channel data from signals in your 8031, 8032, 8051 and 8052-based system.
Refer to information on basic operations to determine how many modules and
probes the logic analyzer needs to meet the channel requirements.
Requirements and Restrictions
You should review the general requirements and restrictions of microcontroller
supports in the information on basic operations as they pertain to your SUT.
You should also review electrical, environmental, and mechanical specifications
in the Specifications chapter in this manual as they pertain to your system under
test, as well as the following descriptions of other 8031, 8032, 8051 and 8052
support requirements and restrictions.
System Clock Rate. The microcontroller support product supports the 8031, 8032,
8051 and 8052 microcontroller at speeds of up to 30 MHz
Hardware Reset. If a hardware reset occurs in your 8031, 8032, 8051 and 8052
system during an acquisition, the disassembler might acquire an invalid sample.
Internal RAM and ROM. The 8051 and 8052 are microcontrollers with internal
RAM and ROM. Only external bus activity (outside the microcontroller) is
disassembled. Internal activity is not present on the bus and cannot be acquired.

Specification at time of printing. Contact your PRISM sales representative for current
information on the fastest devices supported.
TMS 140 Microcontroller Support Instruction Manual
Interrupts and DMA Cycles. The disassembler handles interrupts and DMA cycles
as regular 8031, 8032, 8051 and 8052 cycles because there are no signals on the
8031, 8032, 8051 and 8052 microcontroller to indicate an interrupt or DMA
cycle. Therefore, interrupt and DMA cycles visible on the external bus are
disassembled as data reads and writes.
Connecting to a System Under Test
Before you connect to the SUT, you must connect the probes to the module.
Your SUT must also have a minimum amount of clear space surrounding the
microcontroller to accommodate the probe adapter. Refer to the Specifications
chapter in this manual for the required clearances.
The channel and clock probes shown in this chapter are for a 68/102/136-channel
module. The probes will look different if you are using a 96-channel module.
The general requirements and restrictions of microcontroller supports in the
information on basic operations shows the vertical dimensions of a channel or
clock probe connected to square pins on a circuit board.
Getting Started
DIP Probe Adapter
Refer to the Replaceable Mechanical Parts chapter for part numbers of various
clip adapters and UPIK adapters you can use to connect to a 48-pin DIP and 44-,
68- or 84-pin PLCC packages.
To connect the logic analyzer to a SUT using a DIP probe adapter, follow these
steps:
1. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.
CAUTION. Static discharge can damage the microcontroller, the probe adapter,
the probes, or the module. To prevent static damage, handle all of the above only
in a static-free environment.
Always wear a grounding wrist strap or similar device while handling the
microcontroller and probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. Then, touch any of the ground pins of the
probe adapter to discharge stored static electricity from the probe adapter.
3. Place the probe adapter onto the antistatic shipping foam to support the probe
as shown Figure 1–1. This prevents the circuit board from flexing and the
socket pins from bending.
4. Remove the microcontroller from your SUT.

5. Line up pin 1 on the microcontroller with the pin 1 indicator on the probe
adapter board.
CAUTION. Failure to correctly place the microcontroller into the probe adapter
might permanently damage all electrical components once power is applied.
6. Place the microcontroller into the probe adapter as shown in Figure 1–1.

7. Connect the channel and clock probes to the probe adapter as shown in
Figure 1–2. Match the channel groups and numbers on the probe labels to the
corresponding pins on the probe adapter. Match the ground pins on the
probes to the corresponding pins on the probe adapter.

Channel probe
Hold the channel probes by the podlet
holder when connecting them to the
probe adapter. Do not hold them by
the cables or necks of the podlets.

8. Place the probe adapter onto the SUT as shown in Figure 1–3.
NOTE. You might need to stack one or more replacement sockets between the SUT
and the probe adapter to provide sufficient vertical clearance from adjacent
components. However, keep in mind that this might increase loading, which can
reduce the electrical performance of your probe adapter.

If your microcontroller is soldered to a circuit board and the probe adapter
provides pins to which you can connect a DIP clip, you will need to use the DIP
converter clip with the probe adapter.
One end of the converter clip connects to square pins on the probe adapter. The
other end connects to the microcontroller in your SUT. To connect the logic
analyzer to your SUT using a DIP probe adapter with a clip, refer to Figure 1–4
and follow these steps:
1. Follow steps 1 through 7 in the previous procedure.
2. Connect the cable end to the square pins on the probe adapter.
NOTE. The red strip along the side of the cable indicates that it connects to pin 1
on the probe adapter and pin 1 of the microcontroller.
3. Connect the clip end to the microcontroller.
NOTE. If you are having problems acquiring data, removing pins 18 (XTAL1) and
19 (XTAL2) from the DIP clip may restore proper operation.

You can use channel probes, clock probes, and leadsets with a commercial test
clip (or adapter) to make connections between the logic analyzer and your SUT.
To connect the probes to 8031, 8032, 8051 and 8052 signals in the SUT using a
test clip, follow these steps:
1. Turn off power to your SUT. It is not necessary to turn off power to the logic
analyzer.
CAUTION. Static discharge can damage the microcontroller, the probes, or the
module. To prevent static damage, handle all of the above only in a static-free
environment.
Always wear a grounding wrist strap or similar device while handling the
microcontroller.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. If you are using a test clip, touch any of the
ground pins on the clip to discharge stored static electricity from it.
3. Use Table 1–2 to connect the channel probes to 8031, 8032, 8051 and 8052
signal pins on the test clip or in the SUT.
Use leadsets to connect at least one ground lead from each channel probe and
the ground lead from each clock probe to ground pins on your test clip.
