EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the specified input and output ranges described in
the EVM User’s Guide.
Exceeding the specified input range may cause unexpected operation and/or irreversible
damage to the EVM. If there are questions concerning the input range, please contact a TI
field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or
possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to
connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than
60°C. The EVM is designed to operate properly with certain components above 60°C as long
as the input and output ranges are maintained. These components include but are not limited
to linear regulators, switching transistors, pass transistors, and current sense resistors. These
types of devices can be identified using the EVM schematic located in the EVM User’s Guide.
When placing measurement probes near these devices during operation, please be aware
that these devices may be very warm to the touch.

About This Manual
Contents
Preface
This users guide describes the function and operation of the MSC1211EVM.
This manual will help you quickly set up the evaluation module and its accompanying software, so that you can rapidly test and evaluate the MSC1211. A
complete circuit description, as well as schematic diagram and bill of materials, is included.
How to Use This Manual
This manual begins with an introductory chapter which describes the EVM and
what it can do. If you’re anxious to set things up and start testing, we suggest
you read at least the first two chapters. These two chapters introduce you to
the board and how to set it up to start working with it. Later chapters go into
more detail on the board design and how to access its many features.

MSC1211 Description
1.1 MSC1211 Description
The MSC1211 is a precision 24-bit delta-sigma analog-to-digital converter
(ADC) with an 8051 microcontroller , and up to 32K of flash memory. It has eight
differential/single-ended analog inputs. The delta-sigma architecture
employed in the MSC1211 enables the device to achieve 22 bits of effective
resolution (0.4 5 ppm RMS noise) at a data rate of 10Hz. It can be programmed
for other data rates up to 1kHz that have lower effective resolution. In addition
to the standard 8051 peripherals and functions, the MSC1211 includes four
16-bit digit a l-to-analog converters (DACs), a 32-bit accumulator, a high-speed
2
SPI or I
data RAM, dual UARTS, and dual DPTR registers.
The MSC1211 has a n e nhanced 8 051 c ore t hat o nly r equires 4 c lock c ycles p er
machine cycle. It has extra t imers, watchdog, brownout and low-voltage detect
circuits, power management control and hardware breakpoint registers.
C interface, a 16-bit PWM output, data flash memory, 1,280 bytes of
1.2 EVM System Overview
A block diagram of the MSC1211EVM is shown in Figure 1–1.
During normal operation, programs are developed on the PC and then down-
loaded into the MSC1211 for execution. The primary development environment is Raisonance for assembly and C language programming. There is also
a BASIC–52 and a Basic interpreter available from MDL–Labs.

1.3 Analog Inputs
Analog input is supplied through the ten–way screw terminal block, J4. The
nine inputs are connected to the MSC1211 through a 100Ω resistor. There is
also a terminal block for AGND. The inputs have the 100Ω resistors to provide
minimal protection against overvoltage.
1.4 Prototyping Area
A prototyping area is provided on the MSC121 1EVM. This may be used to incorporate additional circuitry, such as special reference or conditioning circuits, into the system. All of the signals on the MSC1211 are brought to connector pads. Additionally , there are digital and analog power and ground holes
in the prototyping area.
1.5 Power Requirements
The MSC1211EVM must be supplied with 5.5V to 15V for proper operation.
Power can be supplied through barrel jack J6 (tip positive), square pin connectors JMP5 (pins 2 and 3) and JMP6 (pins 2 and 3), or with a 9V battery connected to battery snap B1.
Analog Inputs
A 9V “wall–wart” power supply is included with the MSC1211EVM.
1.6 Host Computer Requirements
The Raisonance software development environment is designed to run on a
PC running any Windows platform (Windows 95, 98, NT, 2000, etc).
Minimum Requirements:
- IBM-compatible 486 PC or higher
- Windows
- 64MB RAM minimum
- 20MB available hard disk space
- CD-ROM drive
- Available serial port
95/98/2000 or NT4.0
