SHORT-FORM DESCRIPTION
CPU
The MSP430 CPU has a 16-bit RISC architecture
that is highly transparent to the application. All
operations, other than program-flow instructions, are
performed as register operations in conjunction with
seven addressing modes for source operand and four
addressing modes for destination operand.

Instruction Set
General-Purpose Register
R12
The instruction set consists of the original 51
instructions with three formats and seven address
modes and additional instructions for the expanded
address range. Each instruction can operate on word
and byte data. Table 4 shows examples of the three
types of instruction formats; Table 5 shows the
address modes.
General-Purpose Register
R13
General-Purpose Register
R14
General-Purpose Register
R15
The CPU is integrated with 16 registers that provide
reduced instruction execution time. The register-toregister operation execution time is one cycle of the
CPU clock.
Four of the registers, R0 to R3, are dedicated as
program counter, stack pointer, status register, and
constant generator, respectively. The remaining
registers are general-purpose registers.

Operating Modes
The MSP430 has one active mode and seven software selectable low-power modes of operation. An interrupt
event can wake up the device from any of the low-power modes, service the request, and restore back to the
low-power mode on return from the interrupt program.
The following seven operating modes can be configured by software:
• Active mode (AM)
– All clocks are active
• Low-power mode 0 (LPM0)
– CPU is disabled
– ACLK and SMCLK remain active, MCLK is disabled
– FLL loop control remains active
• Low-power mode 1 (LPM1)
– CPU is disabled
– FLL loop control is disabled
– ACLK and SMCLK remain active, MCLK is disabled
• Low-power mode 2 (LPM2)
– CPU is disabled
– MCLK, FLL loop control, and DCOCLK are disabled
– DCO's dc generator remains enabled
– ACLK remains active
• Low-power mode 3 (LPM3)
– CPU is disabled
– MCLK, FLL loop control, and DCOCLK are disabled
– DCO's dc generator is disabled
– ACLK remains active
• Low-power mode 4 (LPM4)
– CPU is disabled
– ACLK is disabled
– MCLK, FLL loop control, and DCOCLK are disabled
– DCO's dc generator is disabled
– Crystal oscillator is stopped
– Complete data retention
• Low-power mode 3.5 (LPM3.5)
– Internal regulator disabled
– No data retention
– RTC enabled and clocked by low-frequency oscillator
– Wakeup from RST/NMI, RTC_B, P1, P2, P3, and P4
• Low-power mode 4.5 (LPM4.5)

Bootstrap Loader (BSL)
The BSL enables users to program the flash memory or RAM using a UART serial interfaces. Access to the
device memory via the BSL is protected by an user-defined password. Use of the BSL requires external access
to the six pins shown in Table 8. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and
TEST/SBWTCK pins. For complete description of the features of the BSL and its implementation, see MSP430
Programming Via the Bootstrap Loader (BSL) (SLAU319).

Flash Memory
The flash memory can be programmed via the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the
CPU. The CPU can perform single-byte, single-word, and long-word writes to the flash memory. Features of the
flash memory include:
• Flash memory has n segments of main memory and four segments of information memory (A to D) of
128 bytes each. Each segment in main memory is 512 bytes in size.
• Segments 0 to n may be erased in one step, or each segment may be individually erased.
• Segments A to D can be erased individually, or as a group with segments 0 to n. Segments A to D are also
called information memory.
• Segment A can be locked separately.
RAM Memory
The RAM memory is made up of n sectors. Each sector can be completely powered down to save leakage,
however all data is lost. Features of the RAM memory include:
• RAM memory has n sectors. The size of a sector can be found in Memory Organization.
• Each sector 0 to n can be complete disabled, however data retention is lost.
• Each sector 0 to n automatically enters low power retention mode when possible.
Backup RAM Memory
The backup RAM provides a limited number of bytes of RAM that are retained during LPMx.5 and during
operation from a backup supply if the Battery Backup System module is implemented.
There are 8 bytes of Backup RAM available on MSP430F643x. It can be wordwise accessed via the control
registers BAKMEM0, BAKMEM1, BAKMEM2, and BAKMEM3.
Peripherals
Peripherals are connected to the CPU through data, address, and control buses and can be handled using all
instructions. For complete module descriptions, see the MSP430x5xx and MSP430x6xx Family User's Guide
(SLAU208).
Digital I/O
There are up to nine 8-bit I/O ports implemented: P1 through P9 are complete, and port PJ contains four
individual I/O ports.
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt conditions is possible.
• Programmable pullup or pulldown on all ports.
• Programmable drive strength on all ports.
• Edge-selectable interrupt input capability for all the eight bits of ports P1, P2, P3, and P4.
• Read/write access to port-control registers is supported by all instructions.
• Ports can be accessed byte-wise (P1 through P9) or word-wise in pairs (PA through PD).
Port Mapping Controller
The port mapping controller allows the flexible and reconfigurable mapping of digital functions to port P2.

Oscillator and System Clock
The clock system in the MSP430F643x family of devices is supported by the Unified Clock System (UCS)
module that includes support for a 32-kHz watch crystal oscillator (in XT1 LF mode; XT1 HF mode is not
supported), an internal very-low-power low-frequency oscillator (VLO), an internal trimmed low-frequency
oscillator (REFO), an integrated internal digitally controlled oscillator (DCO), and a high-frequency crystal
oscillator XT2. The UCS module is designed to meet the requirements of both low system cost and low power
consumption. The UCS module features digital frequency locked loop (FLL) hardware that, in conjunction with a
digital modulator, stabilizes the DCO frequency to a programmable multiple of the watch crystal frequency. The
internal DCO provides a fast turn-on clock source and stabilizes in 3 µs (typical). The UCS module provides the
following clock signals:
• Auxiliary clock (ACLK), sourced from a 32-kHz watch crystal (XT1), a high-frequency crystal (XT2), the
internal low-frequency oscillator (VLO), the trimmed low-frequency oscillator (REFO), or the internal digitallycontrolled oscillator DCO.
• Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources available to
ACLK.
• Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by
same sources available to ACLK.
• ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, ACLK/8, ACLK/16, ACLK/32.
Power Management Module (PMM)
The PMM includes an integrated voltage regulator that supplies the core voltage to the device and contains
programmable output levels to provide for power optimization. The PMM also includes supply voltage supervisor
(SVS) and supply voltage monitoring (SVM) circuitry, as well as brownout protection. The brownout circuit is
implemented to provide the proper internal reset signal to the device during power-on and power-off. The SVS
and SVM circuitry detects if the supply voltage drops below a user-selectable level and supports both supply
voltage supervision (the device is automatically reset) and supply voltage monitoring (the device is not
automatically reset). SVS and SVM circuitry is available on the primary supply and core supply.
Hardware Multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs operations with
32-bit, 24-bit, 16-bit, and 8-bit operands. The module is capable of supporting signed and unsigned multiplication
as well as signed and unsigned multiply and accumulate operations.
Real-Time Clock (RTC_B)
The RTC_B module can be configured for real-time clock (RTC) or calendar mode providing seconds, minutes,
hours, day of week, day of month, month, and year. Calendar mode integrates an internal calendar which
compensates for months with less than 31 days and includes leap year correction. The RTC_B also supports
flexible alarm functions and offset-calibration hardware. The implementation on this device supports operation in
LPM3.5 mode and operation from a backup supply.
Watchdog Timer (WDT_A)
The primary function of the watchdog timer (WDT_A) module is to perform a controlled system restart after a
software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog
function is not needed in an application, the module can be configured as an interval timer and can generate
interrupts at selected time intervals.

System Module (SYS)
The SYS module handles many of the system functions within the device. These include power-on reset and
power-up clear handling, NMI source selection and management, reset interrupt vector generators, bootstrap
loader entry mechanisms, and configuration management (device descriptors). SYS also includes a data
exchange mechanism via JTAG called a JTAG mailbox that can be used in the application.

DMA Controller
The DMA controller allows movement of data from one memory address to another without CPU intervention. For
example, the DMA controller can be used to move data from the ADC12_A conversion memory to RAM. Using
the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system
power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or
from a peripheral.

SLAS720B – AUGUST 2010 – REVISED AUGUST 2012
Comparator_B
The primary function of the Comparator_B module is to support precision slope analog-to-digital conversions,
battery voltage supervision, and monitoring of external analog signals.
ADC12_A
The ADC12_A module supports fast 12-bit analog-to-digital conversions. The module implements a 12-bit SAR
core, sample select control, reference generator, and a 16-word conversion-and-control buffer. The conversionand-control buffer allows up to 16 independent ADC samples to be converted and stored without any CPU
intervention.
DAC12_A
The DAC12_A module is a 12-bit R-ladder voltage-output DAC. The DAC12_A may be used in 8-bit or 12-bit
mode, and may be used in conjunction with the DMA controller. When multiple DAC12_A modules are present,
they may be grouped together for synchronous operation.
CRC16
The CRC16 module produces a signature based on a sequence of entered data values and can be used for data
checking purposes. The CRC16 module signature is based on the CRC-CCITT standard.
REF Voltage Reference
The reference module (REF) is responsible for generation of all critical reference voltages that can be used by
the various analog peripherals in the device.
LCD_B
The LCD_B driver generates the segment and common signals that are required to drive a liquid crystal display
(LCD). The LCD_B controller has dedicated data memories to hold segment drive information. Common and
segment signals are generated as defined by the mode. Static, 2-mux, 3-mux, and 4-mux LCDs are supported.
The module can provide a LCD voltage independent of the supply voltage with its integrated charge pump. It is
possible to control the level of the LCD voltage, and thus contrast, by software. The module also provides an
automatic blinking capability for individual segments.
LDO and PU Port
The integrated 3.3-V power system incorporates an integrated 3.3-V LDO regulator that allows the entire
MSP430 microcontroller to be powered from nominal 5-V LDOI when it is made available for the system.
Alternatively, the power system can supply power only to other components within the system, or it can be
unused altogether.
The Port U Pins (PU.0/PU.1) function as general-purpose high-current I/O pins. These pins can only be
configured together as either both inputs or both outputs. Port U is supplied by the LDOO rail. If the 3.3-V LDO is
not being used in the system (disabled), the LDOO pin can be supplied externally.
Embedded Emulation Module (EEM)
The Embedded Emulation Module (EEM) supports real-time in-system debugging. The L version of the EEM
implemented on these devices has the following features:
• Eight hardware triggers/breakpoints on memory access
• Two hardware triggers/breakpoints on CPU register write access
• Up to ten hardware triggers can be combined to form complex triggers/breakpoints
• Two cycle counters
• Sequencer
• State storage
• Clock control on module level

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages referenced to VSS. VCORE is for internal device use only. No external dc loading or voltage should be applied.

It is recommended to power AVCC and DVCC from the same source. A maximum difference of 0.3 V between AVCC and DVCC can be
tolerated during power up and operation.
The minimum supply voltage is defined by the supervisor SVS levels when it is enabled. See the PMM, SVS High Side threshold
parameters for the exact values and further details.
The MSP430 CPU is clocked directly with MCLK. Both the high and low phase of MCLK must not exceed the pulse duration of the
specified maximum frequency.
Modules may have a different maximum input clock specification. See the specification of the respective module in this data sheet.

To improve EMI on the XT1 oscillator, the following guidelines should be observed.
(a) Keep the trace between the device and the crystal as short as possible.
(b) Design a good ground plane around the oscillator pins.
(c) Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
(d) Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
(e) Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins.
(f) If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins.
When XT1BYPASS is set, XT1 circuit is automatically powered down. Input signal is a digital square wave with parametrics defined in
the Schmitt-trigger Inputs section of this datasheet.
Maximum frequency of operation of the entire device cannot be exceeded.
Oscillation allowance is based on a safety factor of 5 for recommended crystals. The oscillation allowance is a function of the
XT1DRIVEx settings and the effective load. In general, comparable oscillator allowance can be achieved based on the following
guidelines, but should be evaluated based on the actual crystal selected for the application:
(a) For XT1DRIVEx = 0, CL,eff ≤ 6 pF.
(b) For XT1DRIVEx = 1, 6 pF ≤ CL,eff ≤ 9 pF.
(c) For XT1DRIVEx = 2, 6 pF ≤ CL,eff ≤ 10 pF.
(d) For XT1DRIVEx = 3, CL,ef f ≥ 6 pF.
Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Since the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency. For a
correct setup, the effective load capacitance should always match the specification of the used crystal.
Requires external capacitors at both terminals. Values are specified by crystal manufacturers.
Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag.
Frequencies in between might set the flag.
Measured with logic-level input frequency but also applies to operation with crystals.

This value represents the time from the wakeup event to the first active edge of MCLK. The wakeup time depends on the performance
mode of the low-side supervisor (SVSL) and low side monitor (SVML). Fastest wakeup times are possible with SVSLand SVML in full
performance mode or disabled when operating in AM, LPM0, and LPM1. Various options are available for SVSLand SVML while
operating in LPM2, LPM3, and LPM4. See the Power Management Module and Supply Voltage Supervisor chapter in the MSP430x5xx
and MSP430x6xx Family User's Guide (SLAU208).
This value represents the time from the wakeup event to the first active edge of MCLK. The wakeup time depends on the performance
mode of the low-side supervisor (SVSL) and low side monitor (SVML). In this case, the SVSLand SVML are in normal mode (low current)
mode when operating in AM, LPM0, and LPM1. Various options are available for SVSLand SVML while operating in LPM2, LPM3, and
LPM4. See the Power Management Module and Supply Voltage Supervisor chapter in the MSP430x5xx and MSP430x6xx Family User's
Guide (SLAU208).

The leakage current is specified by the digital I/O input leakage.
The analog input voltage range must be within the selected reference voltage range VR+ to VR– for valid conversion results. If the
reference voltage is supplied by an external source or if the internal voltage is used and REFOUT = 1, then decoupling capacitors are

The temperature sensor is provided by the REF module. See the REF module parametric, IREF+, regarding the current consumption of
the temperature sensor.
The temperature sensor offset can be significant. A single-point calibration is recommended to minimize the offset error of the built-in
temperature sensor. The TLV structure contains calibration values for 30°C ± 3°C and 85°C ± 3°C for each of the available reference
voltage levels. The sensor voltage can be computed as VSENSE = TCSENSOR × (Temperature,°C) + VSENSOR, where TCSENSOR and
VSENSOR can be computed from the calibration values for higher accuracy. See also the MSP430F5xx and MSP430F6xx Family User's
Guide (SLAU208).
The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time tSENSOR(on).
The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

The external reference is used during ADC conversion to charge and discharge the capacitance array. The input capacitance, Ci, is also
the dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the
recommendations on analog-source impedance to allow the charge to settle for 12-bit accuracy.
The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
The accuracy limits minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.
Two decoupling capacitors, 10 µF and 100 nF, should be connected to VREF to decouple the dynamic current required for an external
reference source if it is used for the ADC12_A. See also the MSP430x5xx and MSP430x6xx Family User's Guide (SLAU208).

The reference is supplied to the ADC by the REF module and is buffered locally inside the ADC. The ADC uses two internal buffers, one
smaller and one larger for driving the VREF+ terminal. When REFOUT = 1, the reference is available at the VREF+ terminal, as well as,
used as the reference for the conversion and utilizes the larger buffer. When REFOUT = 0, the reference is only used as the reference
for the conversion and utilizes the smaller buffer.
The internal reference current is supplied via terminal AVCC. Consumption is independent of the ADC12ON control bit, unless a
conversion is active. REFOUT = 0 represents the current contribution of the smaller buffer. REFOUT = 1 represents the current
contribution of the larger buffer without external load.
The temperature sensor is provided by the REF module. Its current is supplied via terminal AVCC and is equivalent to IREF+ with
REFON = 1 and REFOUT = 0.
For devices without the ADC12, the parametric with ADC12SR = 0 are applicable.
Contribution only due to the reference and buffer including package. This does not include resistance due to PCB traces or other
external factors.
Two decoupling capacitors, 10 µF and 100 nF, should be connected to VREF to decouple the dynamic current required for an external
reference source if it is used for the ADC12_A. See also the MSP430x5xx and MSP430x6xx Family User's Guide (SLAU208).
Calculated using the box method: (MAX(-40 to 85°C) – MIN(-40 to 85°C)) / MIN(-40 to 85°C)/(85°C – (–40°C)).

For a full-scale output, the reference input voltage can be as high as 1/3 of the maximum output voltage swing (AVCC).
The maximum voltage applied at reference input voltage terminal VeREF+ = [AVCC – VE(O)] / [3 × (1 + EG)].
For a full-scale output, the reference input voltage can be as high as the maximum output voltage swing (AVCC).
The maximum voltage applied at reference input voltage terminal VeREF+ = [AVCC – VE(O)] / (1 + EG).
This impedance depends on tradeoff in power savings. Current devices have 48 kΩ for each channel when divide is enabled. Can be
increased if performance can be maintained.
When DAC12IR = 1 and DAC12SREFx = 0 or 1 for both channels, the reference input resistive dividers for each DAC are in parallel
reducing the reference input resistance.

Setting the P5SEL.0 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. An external voltage can be applied to VeREF+ and used as the reference for the ADC12_A, Comparator_B, or
DAC12_A.
Setting the P5SEL.0 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. The ADC12_A, VREF+ reference is available at the pin.
Setting the P5SEL.1 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. An external voltage can be applied to VeREF- and used as the reference for the ADC12_A, Comparator_B, or

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
