Figure 1-1. Functional Block Diagram
The device has one main power pair of DVCC and DVSS that supplies both digital and analog
modules. Recommended bypass and decoupling capacitors are 4.7 µF to 10 µF and 0.1 µF,
respectively, with ±5% accuracy.
P1 and P2 feature the pin-interrupt function and can wake the MCU from LPM3.5.
Each Timer_A3 has three CC registers, but only the CCR1 and CCR2 are externally connected. CCR0
registers can only be used for internal period timing and interrupt generation.
In LPM3.5, the RTC counter can be functional while the remaining peripherals are off.
Not all I/Os are bonded in TSSOP-56 and TSSOP-48 packages (refer to Table 4-1). All I/Os can be
configured as Capacitive Touch I/Os.

Any pin that is not bonded out in a smaller package must be initialized by software after reset to achieve the lowest leakage current.
Because this pin is multiplexed with the JTAG function, TI recommends disabling the pin interrupt function while in JTAG debug to
prevent collisions.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage or memory corruption 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.

Supply voltage changes faster than 0.2 V/µs can trigger a BOR reset even within the recommended supply voltage range. Following the
data sheet recommendation for capacitor CDVCC limits the slopes accordingly.
Modules may have a different supply voltage range specification. See the specification of the respective module in this data sheet.
TI recommends that power to the DVCC pin must not exceed the limits specified in Recommended Operating Conditions. Exceeding the
specified limits can cause malfunction of the device including erroneous writes to RAM and FRAM.
The minimum supply voltage is defined by the SVS levels. See the SVS threshold parameters in Table 5-1.
A capacitor tolerance of ±20% or better is required. A low-ESR ceramic capacitor of 100 nF (minimum) should be placed as close as
possible (within a few millimeters) to the respective pin pair.
Modules may have a different maximum input clock specification. See the specification of the respective module in this data sheet.
Wait states only occur on actual FRAM accesses (that is, on FRAM cache misses). RAM and peripheral accesses are always executed
without wait states.
If clock sources such as HF crystals or the DCO with frequencies >16 MHz are used, the clock must be divided in the clock system to
comply with this operating condition.

A safe BOR can be correctly generated only if DVCC drops below this voltage before it rises.
When an BOR occurs, a safe BOR can be correctly generated only if DVCC is kept low longer than this period before it reaches VSVSH+.

To improve EMI on the LFXT oscillator, 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.
(2) See MSP430 32-kHz Crystal Oscillators for details on crystal section, layout, and testing.
(3) When LFXTBYPASS is set, LFXT circuits are automatically powered down. Input signal is a digital square wave with parametrics
defined in the Schmitt-trigger inputs section of this data sheet. Duty cycle requirements are defined by DCLFXT, SW.
(4) Maximum frequency of operation of the entire device cannot be exceeded.
(5) Oscillation allowance is based on a safety factor of 5 for recommended crystals. The oscillation allowance is a function of the
LFXTDRIVE 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:
• For LFXTDRIVE = {0}, CL,eff = 3.7 pF
• For LFXTDRIVE = {1}, 6 pF ≤ CL,eff ≤ 9 pF
• For LFXTDRIVE = {2}, 6 pF ≤ CL,eff ≤ 10 pF
• For LFXTDRIVE = {3}, 6 pF ≤ CL,eff ≤ 12 pF
(6) Includes parasitic bond and package capacitance (approximately 2 pF per pin).
(7) Requires external capacitors at both terminals to meet the effective load capacitance specified by crystal manufacturers. Recommended
effective load capacitance values supported are 3.7 pF, 6 pF, 9 pF, and 12.5 pF. Maximum shunt capacitance of 1.6 pF. The PCB adds
additional capacitance, so it must also be considered in the overall capacitance. Verify that the recommended effective load capacitance
of the selected crystal is met.
(8) Includes start-up counter of 1024 clock cycles.
(9) Frequencies above the MAX specification do not set the fault flag. Frequencies between the MIN and MAX specification may set the
flag. A static condition or stuck at fault condition sets the flag.
(10) Measured with logic-level input frequency but also applies to operation with crystals.

The temperature sensor offset can vary significantly. TI recommends a single-point calibration to minimize the offset error of the built-in
temperature sensor.
The device descriptor structure contains calibration values for 30°C and 85°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.
The typical equivalent impedance of the sensor is 700 kΩ. The sample time required includes the sensor-on time tSENSOR(on).

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 (PC), stack pointer (SP), status register
(SR), and constant generator (CG), respectively. The remaining registers are general-purpose registers.
Peripherals are connected to the CPU using data, address, and control buses. Peripherals can be handled
with all instructions.
6.2
Operating Modes
The MSP430 has one active mode and several software selectable low-power modes of operation. An
interrupt event can wake up the device from low-power mode LPM0 or LPM3, service the request, and
restore back to the low-power mode on return from the interrupt program. Low-power modes LPM3.5 and
LPM4.5 disable the core supply to minimize power consumption.

JTAG Standard Interface
The MSP430 family supports the standard JTAG interface which requires four signals for sending and
receiving data. The JTAG signals are shared with general-purpose I/O. The TEST/SBWTCK pin is used to
enable the JTAG signals. In addition to these signals, the RST/NMI/SBWTDIO is required to interface with
MSP430 development tools and device programmers. Table 6-4 lists the JTAG pin requirements. For
further details on interfacing to development tools and device programmers, see the MSP430 Hardware
Tools User's Guide. For a complete description of the features of the JTAG interface and its

FRAM
The FRAM can be programmed using the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the
CPU. Features of the FRAM include:
• Byte and word access capability
• Programmable wait state generation
• Error correction coding (ECC)
6.8
Memory Protection
The device features memory protection that can restrict user access and enable write protection:
• Securing the whole memory map to prevent unauthorized access from JTAG port or BSL, by writing
JTAG and BSL signatures using the JTAG port, SBW, the BSL, or in-system by the CPU.
• Write protection enabled to prevent unwanted write operation to FRAM contents by setting the control
bits in System Configuration register 0. For more detailed information, see the SYS chapter in the
MSP430FR4xx and MSP430FR2xx Family User's Guide.
NOTE
The FRAM is protected by default on PUC. To write to FRAM during code execution, the
application must first clear the corresponding PFWP or DFWP bit in System Configuration
Register 0 to unprotect the FRAM.

Peripherals
Peripherals are connected to the CPU through data, address, and control buses. All peripherals can be
handled by using all instructions in the memory map. For complete module description, see the
MSP430FR4xx and MSP430FR2xx Family User's Guide.
6.9.1
Power Management Module (PMM) and On-chip Reference Voltages
The PMM includes an integrated voltage regulator that supplies the core voltage to the device. The PMM
also includes supply voltage supervisor (SVS) and brownout protection. The brownout reset circuit (BOR)
is implemented to provide the proper internal reset signal to the device during power-on and power-off.
The SVS circuitry detects if the supply voltage drops below a user-selectable safe level. SVS circuitry is
available on the primary supply.
The device contains two on-chip reference: 1.5 V for internal reference and 1.2 V for external reference.
The 1.5-V reference is internally connected to ADC channel 13. DVCC is internally connected to ADC
channel 15. When DVCC is set as the reference voltage for ADC conversion, the DVCC can be easily
represent as Equation 1 by using ADC sampling 1.5-V reference without any external components
support.
DVCC = (1023 × 1.5 V) ÷ 1.5-V Reference ADC result
(1)
A 1.2-V reference voltage can be buffered and output to P1.4/MCLK/TCK/A4/VREF+, when the ADC
channel 4 is selected as the function. For more detailed information, see the MSP430FR4xx and
MSP430FR2xx Family User's Guide.
6.9.2
Clock System (CS) and Clock Distribution
The clock system includes a 32-kHz crystal oscillator (XT1), an internal very low-power low-frequency
oscillator (VLO), an integrated 32-kHz RC oscillator (REFO), an integrated internal digitally controlled
oscillator (DCO) that may use frequency-locked loop (FLL) locking with internal or external 32-kHz
reference clock, and on-chip asynchronous high-speed clock (MODCLK). The clock system is designed to
target cost-effective designs with minimal external components. A fail-safe mechanism is designed for
XT1. The clock system module offers the following clock signals.
• Main Clock (MCLK): the system clock used by the CPU and all relevant peripherals accessed by the
bus. All clock sources except MODCLK can be selected as the source with a predivider of 1, 2, 4, 8,
16, 32, 64, or 128.
• Sub-Main Clock (SMCLK): the subsystem clock used by the peripheral modules. SMCLK derives from
the MCLK with a predivider of 1, 2, 4, or 8. This means SMCLK is always equal to or less than MCLK.
• Auxiliary Clock (ACLK): this clock is derived from the external XT1 clock or internal REFO clock up to
40 kHz.
All peripherals may have one or several clock sources depending on specific functionality. Table 6-6
shows the clock distribution used in this device.

Timers (Timer0_A3, Timer1_A3)
The Timer0_A3 and Timer1_A3 modules are 16-bit timers and counters with three capture/compare
registers each. Each timer can support multiple captures or compares, PWM outputs, and interval timing.
Each timer has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow
conditions and from each of the capture/compare registers. The CCR0 registers on both TA0 and TA1 are
not externally connected and can only be used for hardware period timing and interrupt generation. In Up
mode, they can be used to set the overflow value of the counter.

a modulated infrared command for directly driving an external IR diode.
The IR functions are controlled by the following bits in the System Configuration 1 (SYSCFG1) register:
IREN (enable), IRPSEL (polarity select), IRMSEL (mode select), IRDSSEL (data select), and IRDATA
(data). For more information, see the SYS chapter in the MSP430FR4xx and MSP430FR2xx Family

Real-Time Clock (RTC) Counter
The RTC counter is a 16-bit modulo counter that is functional in AM, LPM0, LPM3, and LPM3.5. The RTC
can periodically wake up the CPU from LPM0, LPM3, or LPM3.5 based on timing from a low-power clock
source such as the XT1 and VLO clocks. In AM, RTC can be driven by SMCLK to generate highfrequency timing events and interrupts. The RTC overflow events trigger:
• Timer0_A3 CCR1B
• ADC conversion trigger when ADCSHSx bits are set as 01b
6.9.10 10-Bit Analog Digital Converter (ADC)
The 10-bit ADC module supports fast 10-bit analog-to-digital conversions with single-ended input. The
module implements a 10-bit SAR core, sample select control, reference generator and a conversion result
buffer. A window comparator with a lower and upper limit allows CPU independent result monitoring with
three window comparator interrupt flags.
The ADC supports 10 external inputs and four internal inputs (see Table 6-12).

This value can be directly loaded into DCO bits in CSCTL0 register to get accurate 16-MHz frequency at room temperature, especially
when MCU exits from LPM3 and below. TI suggests using a predivider to decrease the frequency, if the temperature drift might result an
overshoot beyond 16 MHz.

7 Applications, Implementation, and Layout
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
7.1
Device Connection and Layout Fundamentals
This section discusses the recommended guidelines when designing with the MSP430FR413x devices.
These guidelines are to make sure that the device has proper connections for powering, programming,
debugging, and optimum analog performance.
7.1.1
Power Supply Decoupling and Bulk Capacitors
TI recommends connecting a combination of a 10-µF plus a 100-nF low-ESR ceramic decoupling
capacitor to the DVCC and DVSS pins. Higher-value capacitors may be used but can impact supply rail
ramp-up time. Decoupling capacitors must be placed as close as possible to the pins that they decouple
(within a few millimeters).

7.1.2
External Oscillator
This device supports only a low-frequency crystal (32 kHz) on the XIN and XOUT pins. External bypass
capacitors for the crystal oscillator pins are required.
It is also possible to apply digital clock signals to the XIN input pin that meet the specifications of the
respective oscillator if the appropriate XT1BYPASS mode is selected. In this case, the associated XOUT
pin can be used for other purposes. If they are left unused, they must be terminated according to
Section 4.4.
Figure 7-2 shows a typical connection diagram.

7.1.3
www.ti.com
JTAG
With the proper connections, the debugger and a hardware JTAG interface (such as the MSP-FET or
MSP-FET430UIF) can be used to program and debug code on the target board. In addition, the
connections also support the MSP-GANG production programmers, thus providing an easy way to
program prototype boards, if desired. Figure 7-3 shows the connections between the 14-pin JTAG
connector and the target device required to support in-system programming and debugging for 4-wire
JTAG communication. Figure 7-4 shows the connections for 2-wire JTAG mode (Spy-Bi-Wire).
The connections for the MSP-FET and MSP-FET430UIF interface modules and the MSP-GANG are
identical. Both can supply VCC to the target board (through pin 2). In addition, the MSP-FET and MSPFET430UIF interface modules and MSP-GANG have a VCC sense feature that, if used, requires an
alternate connection (pin 4 instead of pin 2). The VCC-sense feature senses the local VCC present on the
target board (that is, a battery or other local power supply) and adjusts the output signals accordingly.
Figure 7-3 and Figure 7-4 show a jumper block that supports both scenarios of supplying VCC to the
target board. If this flexibility is not required, the desired VCC connections may be hard-wired to eliminate
the jumper block. Pins 2 and 4 must not be connected at the same time.
For additional design information regarding the JTAG interface, see the MSP430 Hardware Tools User’s
Guide.

The device RST/NMI/SBWTDIO pin is used in 2-wire mode for bidirectional communication with the device during
JTAG access, and any capacitance that is attached to this signal may affect the ability to establish a connection with
the device. The upper limit for C1 is 1.1 nF when using current TI tools.

Reset
The reset pin can be configured as a reset function (default) or as an NMI function in the Special Function
Register (SFR), SFRRPCR.
In reset mode, the RST/NMI pin is active low, and a pulse applied to this pin that meets the reset timing
specifications generates a BOR-type device reset.
Setting SYSNMI causes the RST/NMI pin to be configured as an external NMI source. The external NMI is
edge sensitive, and its edge is selectable by SYSNMIIES. Setting the NMIIE enables the interrupt of the
external NMI. When an external NMI event occurs, the NMIIFG is set.
The RST/NMI pin can have either a pullup or pulldown that is enabled or not. SYSRSTUP selects either
pullup or pulldown, and SYSRSTRE causes the pullup (default) or pulldown to be enabled (default) or not.
If the RST/NMI pin is unused, it is required either to select and enable the internal pullup or to connect an
external 47-kΩ pullup resistor to the RST/NMI pin with a 1.1-nF pulldown capacitor. The pulldown
capacitor should not exceed 1.1 nF when using devices with Spy-Bi-Wire interface in Spy-Bi-Wire mode or
in 4-wire JTAG mode with TI tools like FET interfaces or GANG programmers.
See the MSP430FR4xx and MSP430FR2xx Family User's Guide for more information on the referenced
control registers and bits.

General Layout Recommendations
•
•
•
•
7.1.7
Proper grounding and short traces for external crystal to reduce parasitic capacitance. See MSP430
32-kHz Crystal Oscillators for recommended layout guidelines.
Proper bypass capacitors on DVCC and reference pins, if used.
Avoid routing any high-frequency signal close to an analog signal line. For example, keep digital
switching signals such as PWM or JTAG signals away from the oscillator circuit.
Proper ESD level protection should be considered to protect the device from unintended high-voltage
electrostatic discharge. See MSP430 System-Level ESD Considerations for guidelines.
Do's and Don'ts
During power up, power down, and device operation, DVCC must not exceed the limits specified in
Section 5.1, Absolute Maximum Ratings. Exceeding the specified limits may cause malfunction of the
device including erroneous writes to RAM and FRAM.

Figure 7-5. ADC Grounding and Noise Considerations
7.2.1.2
Design Requirements
As with any high-resolution ADC, appropriate PCB layout and grounding techniques should be followed to
eliminate ground loops, unwanted parasitic effects, and noise.
Ground loops are formed when return current from the ADC flows through paths that are common with
other analog or digital circuitry. If care is not taken, this current can generate small unwanted offset
voltages that can add to or subtract from the reference or input voltages of the ADC. The general
guidelines in Section 7.1.1 combined with the connections shown in Section 7.2.1.1 prevent this.
In addition to grounding, ripple and noise spikes on the power-supply lines that are caused by digital
switching or switching power supplies can corrupt the conversion result. TI recommends a noise-free
design using separate analog and digital ground planes with a single-point connection to achieve high
accuracy.
Figure 7-5 shows the recommended decoupling circuit when an external voltage reference is used. The
internal reference module has a maximum drive current as described in the sections ADC Pin Enable and
1.2-V Reference Settings of the MSP430FR4xx and MSP430FR2xx Family User's Guide.

SLASE45E – OCTOBER 2014 – REVISED DECEMBER 2019
The reference voltage must be a stable voltage for accurate measurements. The capacitor values that are
selected in the general guidelines filter out the high- and low-frequency ripple before the reference voltage
enters the device. In this case, the 10-µF capacitor is used to buffer the reference pin and filter any lowfrequency ripple. A bypass capacitor of 100 nF is used to filter out any high-frequency noise.
7.2.1.3
Layout Guidelines
Components that are shown in the partial schematic (see Figure 7-5) should be placed as close as
possible to the respective device pins to avoid long traces, because they add additional parasitic
capacitance, inductance, and resistance on the signal.
Avoid routing analog input signals close to a high-frequency pin (for example, a high-frequency PWM),
because the high-frequency switching can be coupled into the analog signal.

with your development, visit the MSP430™ ultra-low-power sensing & measurement MCUs overview.
8.2
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
MSP MCU devices. Each MSP MCU commercial family member has one of two prefixes: MSP or XMS.
These prefixes represent evolutionary stages of product development from engineering prototypes (XMS)
through fully qualified production devices (MSP).
XMS – Experimental device that is not necessarily representative of the final device's electrical
specifications
MSP – Fully qualified production device
XMS devices are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
MSP devices 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) have a greater failure rate than the standard production
devices. TI 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
temperature range, package type, and distribution format. provides a legend for reading the complete
device name.
