Description
The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consists of several devices
featuring different sets of peripherals targeted for various applications. The architecture, combined with
five low-power modes, is optimized to achieve extended battery life in portable measurement applications.
The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute
to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from
low-power modes to active mode in less than 6 µs.
The MSP430FG43x devices are microcontrollers with two 16-bit timers, a high-performance 12-bit ADC,
dual 12-bit DACs, three configurable operational amplifiers, one universal synchronous/asynchronous
communication interface, DMA, 48 I/O pins, and an LCD driver.

Each number in the sequence represents an instantiation of Timer_A with its associated number of capture/compare registers and PWM
output generators available. For example, a number sequence of 3, 5 would represent two instantiations of Timer_A, the first
instantiation having 3 capture/compare registers and PWM output generators and the second instantiation having 5 capture/compare
registers and PWM output generators, respectively.
Each number in the sequence represents an instantiation of Timer_B with its associated number of capture/compare registers and PWM
output generators available. For example, a number sequence of 3, 5 would represent two instantiations of Timer_B, the first
instantiation having 3 capture/compare registers and PWM output generators and the second instantiation having 5 capture/compare
registers and PWM output generators, respectively.

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 operating supply voltage is defined according to the trip point where POR is going active by decreasing the supply
voltage. POR is going inactive when the supply voltage is raised above the minimum supply voltage plus the hysteresis of the SVS
circuitry.
In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.

The leakage current for the Comparator_A terminals is identical to Ilkg(Px.y) specification.
The input offset voltage can be cancelled by using the CAEX bit to invert the Comparator_A inputs on successive measurements. The

The current consumption of the brownout module is already included in the ICC current consumption data. The voltage level V(B_IT–) +
Vhys(B_IT–) is ≤ 1.8 V.
During power up, the CPU begins code execution following a period of td(BOR) after VCC = V(B_IT–) + Vhys(B_IT–). The default FLL+ settings
must not be changed until VCC ≥ VCC(min), where VCC(min) is the minimum supply voltage for the desired operating frequency. See the
MSP430x4xx Family User's Guide (SLAU056) for more information on the brownout/SVS circuit.

tsettle is the settling time that the comparator output needs to have a stable level after VLD is switched from VLD ≠ 0 to a different VLD
value somewhere between 2 and 15. The overdrive is assumed to be > 50 mV.
The recommended operating voltage range is limited to 3.6 V.
The current consumption of the SVS module is not included in the ICC current consumption data.

The parasitic capacitance from the package and board may be estimated to be 2 pF. The effective load capacitor for the crystal is (CXIN
× CXOUT) / (CXIN+ CXOUT). This is independent of XTS_FLL.
To improve EMI on the low-power LFXT1 oscillator, particularly in the LF mode (32 kHz), the following guidelines should be observed.
• Keep the trace between the device and the crystal as short as possible.
• Design a good ground plane around the oscillator pins.
• Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
• Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
• Use assembly materials and processes that avoid any parasitic load on the oscillator XIN and XOUT pins.
• If conformal coating is used, make sure that it does not induce capacitive or resistive leakage between the oscillator pins.
• Do not route the XOUT line to the JTAG header to support the serial programming adapter as shown in other documentation. This
signal is no longer required for the serial programming adapter.
External capacitance is recommended for precision real-time clock applications, OSCCAPx = 0h.
Applies only when using an external logic-level clock source. XTS_FLL must be set. Not applicable when using a crystal or resonator.

The signal applied to the USART0 receive signal/terminal (URXD0) should meet the timing requirements of t(τ) to ensure that the URXS
flip-flop is set. The URXS flip-flop is set with negative pulses meeting the minimum timing condition of t(τ). The operating conditions to
set the flag must be met independently from this timing constraint. The deglitch circuitry is active only on negative transitions on the
URXD0 line.

The leakage current is defined in the leakage current table with Ax parameter.
The analog input voltage range must be within the selected reference voltage range VR+ to VR– for valid conversion results.
The internal reference supply current is not included in current consumption parameter IADC12.
The internal reference current is supplied via terminal AVCC. Consumption is independent of the ADC12ON control bit, unless a
conversion is active. The REFON bit enables to settle the built-in reference before starting an A/D conversion.

The external reference is used during 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.

The internal buffer operational amplifier and the accuracy specifications require an external capacitor. All INL and DNL tests uses two
capacitors between pins VREF+ and AVSS and VREF-–/VeREF– and AVSS: 10 µF tantalum and 100 nF ceramic.
The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB. The settling time depends on the external
capacitive load.

The sensor current ISENSOR is consumed if (ADC12ON = 1 and REFON = 1), or (ADC12ON = 1 AND INCH = 0Ah and sample signal is
high). When REFON = 1, ISENSOR is already included in IREF+.
The temperature sensor offset can be as much as ±20°C. A single-point calibration is recommended in order to minimize the offset error
of the built-in temperature sensor.
The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time tSENSOR(on)
No additional current is needed. The VMID is used during sampling.
The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

Parameters calculated from the best-fit curve from 0x0A to 0xFFF. The best-fit curve method is used to deliver coefficients "a" and "b" of
the first-order equation: y = a + b × x. VDAC12_xOUT = EO + (1 + EG) × (VeREF+ / 4095) × DAC12_xDAT, DAC12IR = 1.
The offset calibration works on the output operational amplifier. Offset Calibration is triggered setting bit DAC12CALON.
The offset calibration can be done if DAC12AMPx = {2, 3, 4, 5, 6, 7}. The output operational amplifier is switched off with DAC12AMPx =
{0, 1}. It is recommended that the DAC12 module be configured prior to initiating calibration. Port activity during calibration may affect
accuracy and is not recommended.

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).
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.

The cumulative program time must not be exceeded when writing to a 64-byte flash block. This parameter applies to all programming
methods: individual word or byte write and block write modes.
The mass erase duration generated by the flash timing generator is at least 11.1 ms ( = 5297 × 1/fFTG,max = 5297 × 1 / 476 kHz). To
achieve the required cumulative mass erase time the Flash Controller's mass erase operation can be repeated until this time is met. (A
worst case minimum of 19 cycles are required).
These values are hard-wired into the flash controller's state machine (tFTG = 1 / fFTG).

6 Detailed Description
6.1
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.
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.
Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all
instructions.

Operating Modes
The MSP430 has one active mode and five software-selectable low-power modes of operation. An
interrupt event can wake up the device from any of the five low-power modes, service the request, and
restore back to the low-power mode on return from the interrupt program.
The following six 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

Bootstrap Loader (BSL)
The MSP430 bootstrap loader (BSL) enables users to program the flash memory or RAM using a UART
serial interface. Access to the MSP430 memory via the BSL is protected by user-defined password. 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, the bootstrap loader, or in system by the CPU.
The CPU can perform single-byte and single-word writes to the flash memory. Features of the flash
memory include:
• Flash memory has n segments of main memory and two segments of information memory (A and B) 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 and B can be erased individually, or as a group with segments 0 to n. Segments A and B
are also called information memory.
• New devices may have some bytes programmed in the information memory (needed for test during
manufacturing). The user should perform an erase of the information memory prior to the first use.

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 MSP430x4xx Family User's Guide (SLAU056).
6.9.1
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 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.
6.9.2
Oscillator and System Clock
The clock system in the MSP430FG43x family of devices is supported by the FLL+ module, which
includes support for a 32768-Hz watch crystal oscillator, an internal digitally-controlled oscillator (DCO),
and a high frequency crystal oscillator. The FLL+ clock module is designed to meet the requirements of
both low system cost and low power consumption. The FLL+ 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 less than 6 µs. The FLL+ module provides the following clock signals:
• Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal or a high-frequency crystal
• Main clock (MCLK), the system clock used by the CPU
• Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules
• ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, or ACLK/8
6.9.3
Brownout, Supply Voltage Supervisor
The brownout circuit is implemented to provide the proper internal reset signal to the device during poweron and power-off. The supply voltage supervisor (SVS) 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).
The CPU begins code execution after the brownout circuit releases the device reset. However, VCC may
not have ramped to VCC(min) at that time. The user must make sure that the default FLL+ settings are not
changed until VCC reaches VCC(min). If desired, the SVS circuit can be used to determine when VCC
reaches VCC(min).
6.9.4
Digital I/O
There are six 8-bit I/O ports implemented—ports P1 through P6:
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt conditions is possible.
• Edge-selectable interrupt input capability for all the eight bits of ports P1 and P2.
• Read and write access to port-control registers is supported by all instructions
6.9.5
Basic Timer1
The Basic Timer1 has two independent 8-bit timers that can be cascaded to form a 16-bit timer/counter.
Both timers can be read and written by software. The Basic Timer1 can be used to generate periodic
interrupts and clock for the LCD module.

6.9.6
SLAS380D – APRIL 2004 – REVISED NOVEMBER 2014
LCD Drive
The LCD driver generates the segment and common signals required to drive an LCD display. The LCD
controller has dedicated data memory 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 by this
peripheral.
6.9.7
OA
The MSP430FG43x has three configurable low-current general-purpose operational amplifiers. Each OA
input and output terminal is software-selectable and offers a flexible choice of connections for various
applications. The OA op amps primarily support front-end analog signal conditioning prior to analog-todigital conversion.
6.9.8
Watchdog Timer (WDT)
The primary function of the WDT 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.
6.9.9
USART0
The MSP430FG43x has one hardware universal synchronous/asynchronous receive transmit (USART)
peripheral module that is used for serial data communication. The USART supports synchronous SPI (3 or
4 pin) and asynchronous UART communication protocols, using double-buffered transmit and receive
channels.
6.9.10 Timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the
capture/compare registers.

6.9.12 Comparator_A
The primary function of the comparator_A module is to support precision slope analog-to-digital
conversions, battery-voltage supervision, and monitoring of external analog signals.
6.9.13 ADC12
The ADC12 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
conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored
without any CPU intervention.
6.9.14 DAC12
The DAC12 module is a 12-bit, R-ladder, voltage output DAC. The DAC12 may be used in 8- or 12-bit
mode, and may be used in conjunction with the DMA controller. When multiple DAC12 modules are
present, they may be grouped together for synchronous operation.

SLAS380D – APRIL 2004 – REVISED NOVEMBER 2014
6.10.23 JTAG Fuse Check Mode
MSP430 devices that have the fuse on the TDI/TCLK terminal have a fuse check mode that tests the
continuity of the fuse the first time the JTAG port is accessed after a power-on reset (POR). When
activated, a fuse check current (I(TF)) of 1 mA at 3 V can flow from the TDI/TCLK pin to ground if the fuse
is not burned. Care must be taken to avoid accidentally activating the fuse check mode and increasing
overall system power consumption.
Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if
the TMS is being held low during power up. The second positive edge on the TMS pin deactivates the
fuse check mode. After deactivation, the fuse check mode remains inactive until another POR occurs.
After each POR the fuse check mode has the potential to be activated.
The fuse check current only flows when the fuse check mode is active and the TMS pin is in a low state
(see Figure 6-8). Therefore, the additional current flow can be prevented by holding the TMS pin high
(default condition). The JTAG pins are terminated internally and therefore do not require external
termination.

7.1
Device Support
7.1.1
Development Support
TI offers an extensive line of development tools, including tools to evaluate the performance of the
processors, generate code, develop algorithm implementations, and fully integrate and debug software
and hardware modules. The tool's support documentation is electronically available within the Code
Composer Studio™ Integrated Development Environment (IDE).
The following products support development of the MSP430FG43x device applications:
Software Development Tools: Code Composer Studio™ Integrated Development Environment (IDE):
including Editor C/C++/Assembly Code Generation, and Debug plus additional development tools.
For a complete listing of development-support tools for the MSP430FG43x platform, visit the Texas
Instruments website at www.ti.com. For information on pricing and availability, contact the nearest TI field
sales office or authorized distributor.
7.1.1.1
Development Kit
The MSP-FET430U80 is a powerful flash emulation tool that includes the hardware and software required
to quickly begin application development on the MSP430 MCU. It includes a ZIF socket target board and a
USB debugging interface (MSP-FET) used to program and debug the MSP430 in-system through the
JTAG interface or the pin saving Spy Bi-Wire (2-wire JTAG) protocol. The flash memory can be erased
and programmed in seconds with only a few keystrokes, and because the MSP430 flash is ultra-low
power, no external power supply is required.
The debugging tool interfaces the MSP430 to the included integrated software environment and includes
code to start your design immediately.
7.1.2
Device and Development Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
MSP430 MCU devices and support tools. Each MSP430 MCU commercial family member has one of
three prefixes: MSP, PMS, or XMS (for example, MSP430F5259). Texas Instruments recommends two of
three possible prefix designators for its support tools: MSP and MSPX. These prefixes represent
evolutionary stages of product development from engineering prototypes (with XMS for devices and MSPX
for tools) through fully qualified production devices and tools (with MSP for devices and MSP for tools).
Device development evolutionary flow:
XMS – Experimental device that is not necessarily representative of the final device's electrical
specifications
PMS – Final silicon die that conforms to the device's electrical specifications but has not completed quality
and reliability verification
MSP – Fully qualified production device
Support tool development evolutionary flow:
MSPX – Development-support product that has not yet completed Texas Instruments internal qualification
testing.
MSP – Fully-qualified development-support product
XMS and PMS devices and MSPX development-support tools are shipped against the following
disclaimer:
"Developmental product is intended for internal evaluation purposes."

SLAS380D – APRIL 2004 – REVISED NOVEMBER 2014
MSP devices and MSP development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (XMS and PMS) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate still is undefined. Only qualified production devices are
to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, PZP) and temperature range (for example, T). Figure 7-1 provides a legend
for reading the complete device name for any family member.

Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

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.

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

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 JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. 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 as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
