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.
The CPU is integrated with 16 registers that provide
reduced
instruction
execution
time.
The
register-to-register 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.
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.

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 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 and 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

Multiple source flags
A reset is generated if the CPU tries to fetch instructions from within peripheral space or vacant memory space.
(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot disable it.
Interrupt flags are located in the module.
Reserved interrupt vectors at addresses are not used in this device and can be used for regular program code if necessary. To maintain
compatibility with other devices, it is recommended to reserve these locations.

Bootstrap Loader (BSL)
The BSL enables users to program the flash memory or RAM using a UART serial interface. Access to the
device memory via the BSL is protected by an user-defined password. Usage of the BSL requires four pins as
shown in Table 3. 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 the MSP430 Memory
Programming User's Guide, literature number SLAU265.

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. The JTAG pin requirements are shown in Table 4. For further
details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's
Guide, literature number SLAU278.

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. 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.
• For Devices that contain USB memory, the USB memory can be used as normal RAM if USB is not required.

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 Family User's Guide, literature number
SLAU208.
Digital I/O
There are up to ten 8-bit I/O ports implemented: For 100-pin options, P1 through P10 are complete. P11 contains
three individual I/O ports. For 80-pin options, P1 through P7 are complete. P8 contains seven individual I/O ports.
P9 through P11 do not exist. Port PJ contains four individual I/O ports, common to all devices.
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt conditions is possible.
• Pullup or pulldown on all ports is programmable.
• Drive strength on all ports is programmable.
• Edge-selectable interrupt and LPM5 wakeup input capability is available for all bits of ports P1 and P2.
• Read/write access to port-control registers is supported by all instructions.
• Ports can be accessed byte-wise (P1 through P11) or word-wise in pairs (PA through PF).
Oscillator and System Clock
The clock system in the MSP430x5xx family of devices is supported by the Unified Clock System (UCS) module
that includes support for a 32-kHz watch crystal oscillator (XT1 LF mode), 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 (XT1 HF mode or 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 selected FLL reference frequency. The internal
DCO provides a fast turn-on clock source and stabilizes in less than 5 µs. The UCS module provides the
following clock signals:
• Auxiliary clock (ACLK), sourced from a 32-kHz watch crystal, a high-frequency crystal, the internal
low-frequency oscillator (VLO), the trimmed low-frequency oscillator (REFO), or the internal digitally controlled
oscillator DCO.
• Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources made
available to ACLK.
• Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by
same sources made 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/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 (SVM, 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_A)
The RTC_A module can be used as a general-purpose 32-bit counter (counter mode) or as an integrated
real-time clock (RTC) (calendar mode). In counter mode, the RTC_A also includes 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. Calendar
mode integrates an internal calendar which compensates for months with less than 31 days and includes leap
year correction. The RTC_A also supports flexible alarm functions and offset-calibration hardware.
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.

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.

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 circuits are 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,ef f ≤ 6 pF.
(b) For XT1DRIVEx = 1, 6 pF ≤ CL,ef f ≤ 9 pF.
(c) For XT1DRIVEx = 2, 6 pF ≤ CL,ef f ≤ 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.

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 reference voltage is used and REFOUT = 1, then decoupling
capacitors are required. See 12-Bit ADC, External Reference and 12-Bit ADC, Built-In Reference.
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. No external load.

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.
Two decoupling capacitors, 10µF and 100nF, 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 Family User's Guide (SLAU208).

Two decoupling capacitors, 10µF and 100nF, 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 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))
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).
The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

The pin direction is controlled by the USCI module.
UCA0CLK function takes precedence over UCB0STE function. If the pin is required as UCA0CLK input or output, USCI A0/B0 is forced
to 3-wire SPI mode if 4-wire SPI mode is selected.
If the I2C functionality is selected, the output drives only the logical 0 to VSS level.
UCA1CLK function takes precedence over UCB1STE function. If the pin is required as UCA1CLK input or output, USCI A1/B1 is forced
to 3-wire SPI mode if 4-wire SPI mode is selected.

The pin direction is controlled by the USCI module.
UCA2CLK function takes precedence over UCB2STE function. If the pin is required as UCA2CLK input or output, USCI A2/B2 is forced
to 3-wire SPI mode if 4-wire SPI mode is selected.
If the I2C functionality is selected, the output drives only the logical 0 to VSS level.

The pin direction is controlled by the USCI module.
UCA3CLK function takes precedence over UCB3STE function. If the pin is required as UCA3CLK input or output, USCI A3/B3 is forced
to 3-wire SPI mode if 4-wire SPI mode is selected.
If the I2C functionality is selected, the output drives only the logical 0 to VSS level.
The secondary function on these pins are reserved for factory test purposes. Application should keep the P10SEL.x of these ports
cleared to prevent potential conflicts with the application.

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)

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
