description
The Texas Instruments MSP430 family of ultralow-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 calibrated digitally controlled oscillator (DCO) allows wake-up from low-power modes to active
mode in less than 1 s.
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. These devices have limited
built-in ESD protection.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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.
Program Counter
PC/R0
Stack Pointer
SP/R1
SR/CG1/R2
Status Register
Constant Generator
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.
instruction set
The instruction set consists of 51 instructions with
three formats and seven address modes. Each
instruction can operate on word and byte data.
Table 1 shows examples of the three types of
instruction formats; the address modes are listed
in Table 2.

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:
D Active mode (AM)

interrupt vector addresses
The interrupt vectors and the power-up starting address are located in the address range 0x0FFFF to 0x0FFC0.
The vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence. If the reset
vector (0x0FFFE) contains 0xFFFF (e.g., flash is not programmed), the CPU enters LPM4 after power-up.

NOTES: 1. A reset is executed if the CPU tries to fetch instructions from within the module register memory address range (0x00000 to 0x001FF)
or from within unused address ranges.
2. Multiple source flags.
3. Interrupt flags are located in the module.
4. In SPI mode: UCB0RXIFG. In I2C mode: UCALIFG, UCNACKIFG, ICSTTIFG, UCSTPIFG.
5. In UART/SPI mode: UCB0TXIFG. In I2C mode: UCB0RXIFG, UCB0TXIFG.
6. (Non)maskable: The individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot.
7. The address 0x0FFBE is used as bootstrap loader security key (BSLSKEY).
A 0x0AA55 at this location disables the BSL completely.
A zero disables the erasure of the flash if an invalid password is supplied.
8. The interrupt vectors at addresses 0x0FFDA to 0x0FFC0 are not used in this device and can be used for regular program code if
necessary.

bootstrap loader (BSL)
The MSP430 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 a user-defined password. For complete description of the
features of the BSL and its implementation, see the application report Features of the MSP430 Bootstrap
Loader, literature number SLAA089.

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:
D 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.
D Segments 0 to n may be erased in one step, or each segment may be individually erased.
D 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.
D Segment A contains calibration data. After reset, segment A is protected against programming or erasing.
It can be unlocked, but care should be taken not to erase this segment if the calibration data is required.
D Flash content integrity check with marginal read modes
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, literature number

MIXED SIGNAL MICROCONTROLLER
SLAS632 -- DECEMBER 2008
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.
oscillator and system clock
The clock system in the MSP43x261x family of devices 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 s. The basic clock module provides the following clock
signals:
D Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, or a very
low-power LF oscillator
D Main clock (MCLK), the system clock used by the CPU
D Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules
The DCO settings to calibrate the DCO output frequency are stored in the information memory segment A.

brownout, supply voltage supervisor (SVS)
The brownout circuit 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 level and supports
both supply voltage supervision (the device is automatically reset) and supply voltage monitoring (SVM) (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 ensure that the default DCO settings are not changed until
VCC reaches VCC(min). If desired, the SVS circuit can be used to determine when VCC reaches VCC(min).
digital I/O
There are up to eight 8-bit I/O ports implemented—ports P1 through P8:
D
D
D
D
D
D
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 eight bits of ports 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.
Ports P7/P8 can be accessed word-wise.

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.
hardware multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs 16×16,
16×8, 8×16, and 8×8 bit operations. The module is capable of supporting signed and unsigned multiplication
as well as signed and unsigned multiply and accumulate operations. The result of an operation can be accessed
immediately after the operands have been loaded into the peripheral registers. No additional clock cycles are
required.
universal serial communication interface (USCI)
The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols such as SPI (3 pin or 4 pin) or I2C, and asynchronous combination protocols such as
UART, enhanced UART with automatic baudrate detection (LIN), and IrDA.
The USCI A module provides support for SPI (3 pin or 4 pin), UART, enhanced UART, and IrDA.
The USCI B module provides support for SPI (3 pin or 4 pin) and I2C.

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.
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.
DAC12
The DAC12 module is a 12-bit, R-ladder, voltage-output digital-to-analog converter (DAC). The DAC12 may be
used in 8-bit 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.

NOTES: 1. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended
operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
2. All voltages referenced to VSS. The JTAG fuse-blow voltage, VFB, is allowed to exceed the absolute maximum rating. The voltage
is applied to the TDI/TCLK pin when blowing the JTAG fuse.
3. Higher temperature may be applied during board soldering process according to the current JEDEC J-STD-020 specification, with
peak reflow temperatures not higher than classified on the device label on the shipping boxes or reels.

NOTES: 1. 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.
2. The MSP430 CPU is clocked directly with MCLK.
Both the high and low phase of MCLK must not exceed the pulse width of the specified maximum frequency.
3. Modules might have a different maximum input clock specification. See the specification of the respective module in this data sheet.

NOTES: 1. 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.
2. Measured with logic level input frequency but also applies to operation with crystals.
3. Frequencies below the MIN specification set the fault flag, frequencies above the MAX specification do not set the fault flag, and
frequencies in between might set the flag.
4. To improve EMI on the LFXT1 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 under or adjacent to the XIN and XOUT pins.
-- Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins.
-- If conformal coating is used, ensure that it does not induce capacitive/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.
5. Applies only if using an external logic-level clock source. Not applicable when using a crystal or resonator.

5. To improve EMI on the LFXT1 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 under or adjacent to the XIN and XOUT pins.
-- Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins.
-- If conformal coating is used, ensure that it does not induce capacitive/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.

NOTES: 1. The leakage current for the Comparator_A+ terminals is identical to Ilkg(Px.x) specification.
2. 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.
3. The response time is measured at P2.2/CAOUT/TA0/CA4 with an input voltage step, with Comparator_A+ already enabled
(CAON = 1). If CAON is set at the same time, a settling time of up to 300 ns is added to the response time.

NOTES: 1. The leakage current is defined in the leakage current table with P6.x/Ax parameter.
2. The analog input voltage range must be within the selected reference voltage range VR+ to VR-- for valid conversion results.
3. The internal reference supply current is not included in current consumption parameter IADC12.
4. 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.

NOTES: 1. 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.
2. The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
3. The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
4. The accuracy limits minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.

two capacitors between pins VREF+ and AVSS and VREF-- /VeREF-- and AVSS: 10 F tantalum and 100 nF ceramic.
2. 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.

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

NOTES: 1. 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.
2. The offset calibration works on the output operational amplifier. Offset calibration is triggered setting bit DAC12CALON.
3. 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}. The DAC12 module should 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.

NOTES: 1. 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/byte write and block write modes.
2. The mass erase duration generated by the flash timing generator is at least 11.1 ms ( = 5297x1/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 is required.
3. These values are hardwired into the Flash Controller’s state machine (tFTG = 1/fFTG).
4. To erase the complete code area, the mass erase must be performed once with a dummy address in the range of the lower 64-kB
flash addresses and once with the dummy address in the upper 64-kB flash addresses.

APPLICATION INFORMATION
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, ITF, of 1 mA at 3 V or 2.5 mA at 5 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 flows only when the fuse check mode is active and the TMS pin is in a low state (see
Figure 49). Therefore, the additional current flow can be prevented by holding the TMS pin high (default
condition).
