3 Description
The Texas Instruments MSP430™ family of ultra-lowpower 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
digitally controlled oscillator (DCO) allows the device
to wake up from low-power modes to active mode in
less than 1 µs.
The MSP430G2x53 series are ultra-low-power mixed
signal microcontrollers with built-in 16-bit timers, up to
24 I/O capacitive-touch enabled pins, a versatile
analog comparator, a 10-bit analog-to-digital (A/D)
converter, and built-in communication capability using
the universal serial communication interface. For
configuration details, see Table 1.
Typical applications include low-cost sensor systems
that capture analog signals, convert them to digital
values, and then process the data for display or for
transmission to a host system.

8 Detailed Description
8.1 CPU
Instruction Set (continued)
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
Status Register
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.

8.2 Instruction Set
General-Purpose Register
R13
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.
General-Purpose Register
R14
General-Purpose Register
R15
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.

8.3 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
• Low-power mode 1 (LPM1)
– CPU is disabled
– ACLK and SMCLK remain active, MCLK is disabled
– DCO's 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's dc generator remains enabled
– ACLK remains active
• Low-power mode 3 (LPM3)
– CPU is disabled

8.4 Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range 0FFFFh to 0FFC0h.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
If the reset vector (located at address 0FFFEh) contains 0FFFFh (for example, flash is not programmed), the
CPU goes into LPM4 immediately after power-up.

A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h to 01FFh) or from
within unused address ranges.
Multiple source flags
(non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
Interrupt flags are located in the module.
In SPI mode: UCB0RXIFG. In I2C mode: UCALIFG, UCNACKIFG, ICSTTIFG, UCSTPIFG.
In UART or 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 (0h)
disables the erasure of the flash if an invalid password is supplied.
The interrupt vectors at addresses 0FFDEh to 0FFC0h are not used in this device and can be used for regular program code if
necessary.

8.7 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. For complete description of the
features of the BSL and its implementation, see the MSP430 Programming Via the Bootstrap Loader User's
Guide (SLAU319).

8.8 Flash Memory
The flash memory can be programmed via the Spy-Bi-Wire/JTAG port 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.

8.9 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).
8.9.1 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 and an internal digitally controlled oscillator (DCO).
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 either from a 32768-Hz watch crystal or the internal 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.
8.9.2 Main DCO Characteristics
• 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 =
14
32 × fDCO(RSEL,DCO) × fDCO(RSEL,DCO+1)
MOD × fDCO(RSEL,DCO) + (32 – MOD) × fDCO(RSEL,DCO+1)

8.9.4 Brownout
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on and
power off.
8.9.5 Digital I/O
Up to three 8-bit I/O ports are implemented:
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt condition (port P1 and port P2 only) is possible.
• Edge-selectable interrupt input capability for all bits of port P1 and port P2 (if available).
• Read/write access to port-control registers is supported by all instructions.
• Each I/O has an individually programmable pullup or pulldown resistor.
• Each I/O has an individually programmable pin oscillator enable bit to enable low-cost capacitive touch
detection.
8.9.6 Watchdog Timer (WDT+)
The primary function of the watchdog timer (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.

8.9.8 Universal Serial Communications Interface (USCI)
The USCI module is used for serial data communication. The USCI module supports synchronous
communication protocols such as SPI (3 or 4 pin) and I2C, and asynchronous communication protocols such as
UART, enhanced UART with automatic baudrate detection (LIN), and IrDA. Not all packages support the USCI
functionality.
USCI_A0 provides support for SPI (3 or 4 pin), UART, enhanced UART, and IrDA.
USCI_B0 provides support for SPI (3 or 4 pin) and I2C.
8.9.9 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.
8.9.10 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 (DTC) for automatic conversion
result handling, allowing ADC samples to be converted and stored without any CPU intervention.

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.
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 TEST pin when blowing the JTAG fuse.
Higher temperature may be applied during board soldering 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.

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 processes that avoid any parasitic load on the oscillator XIN and XOUT pins.
(f) If a conformal coating is used, ensure that it does not induce capacitive or 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 used crystal.
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 DCO wake-up time must be considered in LPM3 and LPM4 for baud rates above 1 MHz.
Pulses on the UART receive input (UCxRX) shorter than the UART receive deglitch time are suppressed. To ensure that pulses are

The leakage current is defined in the leakage current table with Px.y/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 to settle before starting an A/D conversion.

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]
The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time tSENSOR(on).
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.

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 write, individual byte write, and block write modes.
These values are hardwired into the Flash Controller's state machine (tFTG = 1/fFTG).

The following links connect to TI community resources. Linked contents are provided "AS IS" by the respective

Texas Instruments Embedded Processors Wiki. Established to help developers get started with embedded
processors from Texas Instruments and to foster innovation and growth of general knowledge about the
hardware and software surrounding these devices.
11.1.2 Device and Development Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
MSP430™ MCU devices and support tools. Each MSP430™ MCU commercial family member has one of three
prefixes: MSP, PMS, or XMS (for example, MSP430F5259). Texas Instruments recommends two of three
possible prefix designators for its support tools: MSP and MSPX. These prefixes represent evolutionary stages of
product development from engineering prototypes (with XMS for devices and MSPX for tools) through fully
qualified production devices and tools (with MSP for devices and MSP for tools).
Device development evolutionary flow:
XMS – Experimental device that is not necessarily representative of the final device's electrical specifications
PMS – Final silicon die that conforms to the device's electrical specifications but has not completed quality and
reliability verification
MSP – Fully qualified production device
Support tool development evolutionary flow:
MSPX – Development-support product that has not yet completed Texas Instruments internal qualification
testing.
MSP – Fully-qualified development-support product
XMS and PMS devices and MSPX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
MSP devices and MSP development-support tools 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 and PMS) have a greater failure rate than the standard production
devices. Texas Instruments 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 package type
(for example, PZP) and temperature range (for example, T). Figure 25 provides a legend for reading the
complete device name for any family member.
