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 devices feature
a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code
efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less
than 6 µs.
The MSP430x461x(1) series are microcontroller configurations with two 16-bit timers, a high-performance
12-bit A/D converter (MSP430x461x only), one universal serial communication interface (USCI), one universal
synchronous/asynchronous communication interface (USART), DMA, 80 I/O pins, and a liquid crystal display
(LCD) driver with regulated charge pump.
Typical applications for this device include portable medical applications and e-meter applications.
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.
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 MSP430x461x(1) device family uses the MSP430X
CPU and is completely backward compatible with the
MSP430 CPU. For a complete description of the MSP430X
CPU, see the MSP430x4xx Family User’s Guide.

instruction set
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. Table 1
shows examples of the three types of instruction formats;
Table 2 shows the address modes.

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)

NOTES: 1. Multiple source flags
2. Interrupt flags are located in the module.
3. A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h to 01FFh).
(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot disable it.
4. The interrupt vectors at addresses 0FFDAh to 0FFC0h are not used in this device and can be used for regular program code if
necessary.
5. Access and key violations, KEYV and ACCVIFG, only applicable to F devices.
6. ADC12 is not implemented in MSP430x461x1 devices.

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 user-defined password. A bootstrap loader security key is
provided at address 0FFBEh to disable the BSL completely or to disable the erasure of the flash if an invalid
password is supplied. The BSL is optional for ROM-based devices. 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 two segments of information memory (A and B) of
128 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 and B can be erased individually, or as a group with segments 0 to n.
Segments A and B are also called information memory.
D 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, literature number
SLAU056.
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 MSP430x461x(1) 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:
D
D
D
D
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
brownout, supply voltage supervisor
The brownout circuit is implemented to provide the proper internal reset signal to the device during power-on
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 (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 insure 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).
digital I/O
There are ten 8-bit I/O ports implemented—ports P1 through P10:
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 the eight bits of ports P1 and P2.
Read/write access to port-control registers is supported by all instructions.
Ports P7/P8 and P9/P10 can be accessed word-wise as ports PA and PB respectively.
Basic Timer1 and Real-Time Clock (RTC)
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. Basic Timer1 is extended to provide an integrated real-time clock
(RTC). An internal calendar compensates for months with less than 31 days and includes leap-year correction.

MIXED SIGNAL MICROCONTROLLER
LCD_A drive with regulated charge pump
The LCD_A driver generates the segment and common signals required to drive an LCD display. The LCD_A
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.
The module can provide a LCD voltage independent of the supply voltage with its integrated charge pump.
Furthermore it is possible to control the level of the LCD voltage and, thus, contrast by software.
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.
universal serial communication interface (USCI)
The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols like SPI (3 or 4 pin), I2C and asynchronous communication protocols like UART,
enhanced UART with automatic baudrate detection, and IrDA.
The USCI_A0 module provides support for SPI (3 or 4 pin), UART, enhanced UART and IrDA.
The USCI_B0 module provides support for SPI (3 or 4 pin) and I2C.
USART1
The hardware universal synchronous/asynchronous receive transmit (USART) peripheral module 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.
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.

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.
NOTE: 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.

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 and operation.
2. 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.
3. In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.

NOTES: 1. Enabling the internal charge pump with an external capacitor smaller than the minimum specified might damage the device.
2. Refer to the supply current specifications I(LPM3) for additional current specifications with the LCD_A module active.
3. Segments S0 through S3 are disabled when the LCD charge pump feature is enabled (LCDCPEN = 1) and cannot be used together
with the LCD charge pump. In addition, when using segments S0 through S3 with an external LCD voltage supply, VLCD ≤ AVCC.
4. Connecting an actual display will increase the current consumption depending on the size of the LCD.

NOTES: 1. The current consumption of the brownout module is already included in the ICC current consumption data.
2. The voltage level V(B_IT−) + Vhys(B_IT−) is ≤ 1.89V.
3. 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 for more information on the brownout/SVS circuit.

NOTES: 1. The parasitic capacitance from the package and board may be estimated to be 2 pF. The effective load capacitor for the crystal is
(CXIN x CXOUT) / (CXIN + CXOUT). This is independent of XTS_FLL.
2. 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 MSP430 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 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.
3. Applies only when using an external logic-level clock source. XTS_FLL must be set. Not applicable when using a crystal or resonator.
4. External capacitance is recommended for precision real-time clock applications; OSCCAPx = 0h.

NOTE 1: The signal applied to the USART1 receive signal/terminal (URXD1) 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
URXD1 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.

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.

NOTES: 1. 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+.
2. 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.
3. The typical equivalent impedance of the sensor is 51 kΩ. 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.

MIXED SIGNAL MICROCONTROLLER
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 26). 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.
