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.

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 instruction set consists of 51 instructions with
three formats and seven address modes. Each
instruction can operate on word and byte data.
Table 3 shows examples of the three types of
instruction formats; Table 4 shows the address
modes.

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.

Operating Modes
The MSP430 microcontrollers have 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.
• Low-power mode 1 (LPM1)
– CPU is disabled ACLK and SMCLK remain active. MCLK is disabled.
– DCO dc-generator is disabled if DCO not used in active mode.
• Low-power mode 2 (LPM2)
– CPU is disabled.
– MCLK and SMCLK are disabled.
– DCO dc-generator remains enabled.
– ACLK remains active.
• Low-power mode 3 (LPM3)
– CPU is disabled.
– MCLK and SMCLK are disabled.
– DCO dc-generator is disabled.
– ACLK remains active.
• Low-power mode 4 (LPM4)
– CPU is disabled.
– ACLK is disabled.
– MCLK and SMCLK are disabled.
– DCO dc-generator is disabled.
– Crystal oscillator is stopped.

Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range of 0xFFFF to 0xFFC0.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
If the reset vector (located at address 0xFFFE) contains 0xFFFF (for example, if flash is not programmed), the
CPU goes into LPM4 immediately after power up.

Multiple source flags
A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0x0000 to 0x01FF) or
from within unused address range.
(non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
Nonmaskable: neither the individual nor the general interrupt-enable bit will disable an interrupt event.
Interrupt flags are located in the module.
In SPI mode: UCB0RXIFG. In I2C mode: UCALIFG, UCNACKIFG, ICSTTIFG, UCSTPIFG
In UART/SPI mode: UCB0TXIFG. In I2C mode: UCB0RXIFG, UCB0TXIFG
This location is used as bootstrap loader security key (BSLSKEY).
A 0xAA55 at this location disables the BSL completely.
A zero (0x0) disables the erasure of the flash if an invalid password is supplied.
The interrupt vectors at addresses 0xFFDC to 0xFFC0 are not used in this device and can be used for regular program code if
necessary.

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 the MSP430 Programming Via the Bootstrap
Loader User’s Guide, literature number 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 four segments of information memory (A to D) of
64 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 contains calibration data. After reset, segment A is protected against programming and erasing. It
can be unlocked, but care should be taken not to erase this segment if the device-specific calibration data is
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 MSP430x2xx Family User's Guide (SLAU144).
Oscillator and System Clock
The clock system is supported by the basic clock module that includes support for a 32768-Hz watch crystal
oscillator, an internal very-low-power low-frequency oscillator, an internal digitally-controlled oscillator (DCO), and
a high-frequency crystal oscillator. The basic clock module is designed to meet the requirements of both low
system cost and low power consumption. The internal DCO provides a fast turn-on clock source and stabilizes in
less than 1 µs. The basic clock module provides the following clock signals:
• Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, or the internal
very-low-power LF oscillator.
• Main clock (MCLK), the system clock used by the CPU.
• Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.
The DCO settings to calibrate the DCO output frequency are stored in the information memory segment A.
Calibration Data Stored in Information Memory Segment A
Calibration data is stored for both the DCO and for ADC10 organized in a tag-length-value (TLV) structure.

SLAS578J – NOVEMBER 2007 – REVISED JANUARY 2012
Brownout
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on and
power off.
Digital I/O
There are three 8-bit I/O ports implemented—ports P1, P2, and P3:
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt condition is possible.
• Edge-selectable interrupt input capability for all eight bits of port P1 and P2.
• Read/write access to port-control registers is supported by all instructions.
• Each I/O has an individually programmable pullup/pulldown resistor.
The MSP430F21x2 devices provide up to 24 total port I/O pins available externally. See the device pinout for
more information.
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 disabled or configured as an interval timer and can generate interrupts at
selected time intervals.
ADC10
The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR
core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion
result handling allowing ADC samples to be converted and stored without any CPU intervention.
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.

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 DCO settings
must not be changed until VCC ≥ VCC(min), where VCC(min) is the minimum supply voltage for the desired operating frequency.

All ranges selected by RSELx overlap with RSELx + 1: RSELx = 0 overlaps RSELx = 1, ... RSELx = 14
overlaps RSELx = 15.
DCO control bits DCOx have a step size as defined by parameter SDCO.
Modulation control bits MODx select how often fDCO(RSEL,DCO+1) is used within the period of 32 DCOCLK
cycles. The frequency fDCO(RSEL,DCO) is used for the remaining cycles. The frequency is an average equal to:
faverage =
32 × fDCO(RSEL,DCO) × fDCO(RSEL,DCO+1)
MOD × fDCO(RSEL,DCO) + (32 – MOD) × fDCO(RSEL,DCO+1)

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.
(g) 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.
Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Because 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 crystal that is used.
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 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
two successive measurements are then summed together.
Response time measured at P2.2/TA0.0/A2/CA4/CAOUT. If the Comparator_A+ is enabled a settling time of 60 ns (typical) is added to
the response time.

The leakage current is defined in the leakage current table with Px.x/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 IADC10.
The internal reference current is supplied via terminal VCC. Consumption is independent of the ADC10ON control bit, unless a
conversion is active. The REFON bit enables the built-in reference. The reference voltage must be allowed to settle before an A/D
conversion is started.

The capacitance applied to the internal buffer operational amplifier, if switched to terminal P2.4/TA2/A4/VREF+/VeREF+ (REFOUT = 1),
must be limited; otherwise, the reference buffer may become unstable.
Calculated using the box method: ((MAX(VREF(T)) -- MIN(VREF(T))) / MIN(VREF(T)) / (TMAX - TMIN)
The condition is that the error in a conversion started after tREFON or tRefBuf is less than ±0.5 LSB.

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 10-bit accuracy.
The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
Under this condition, the external reference is internally buffered. The reference buffer is active and requires the reference buffer supply
current IREFB. The current consumption can be limited to the sample and conversion period with REBURST = 1.
The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
The accuracy limits the minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.

The sensor current ISENSOR is consumed if (ADC10ON = 1 and REFON = 1) or (ADC10ON = 1 and INCH = 0Ah and sample signal is
high). When REFON = 1, ISENSOR is included in IREF+.When REFON = 0, ISENSOR applies during conversion of the temperature sensor
input (INCH = 0Ah).
The following formula can be used to calculate the temperature sensor output voltage:
VSensor,typ = TCSensor ( 273 + T [°C] ) + VOffset,sensor [mV] or
VSensor,typ = TCSensor T [°C] + VSensor(TA = 0°C) [mV]
Results based on characterization and/or production test, not TCSensor or VOffset,sensor.
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.

JTAG Fuse Check Mode
MSP430 devices that have the fuse on the TEST 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, ITF , of 1 mA at 3 V, 2.5 mA at 5 V can flow from the TEST 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.
When the TEST pin is again taken low after a test or programming session, the fuse check mode and sense
currents are terminated.
Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if 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 flows only when the fuse check mode is active and the TMS pin is in a low state (see
Figure 31). Therefore, the additional current flow can be prevented by holding the TMS pin high (default
condition).
Time TMS Goes Low After POR

NOTE
The CODE and RAM data protection is ensured if the JTAG fuse is blown and the 256-bit
bootloader access key is used. Also, see the Bootstrap Loader section for more
information.

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)

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.
