description
The Texas Instruments MSP430 family of ultralow-power microcontrollers consist 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 attribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6µs.
The MSP430x11x2 and MSP430x12x2 series are ultralow-power mixed signal microcontrollers with a built-in
16-bit timer, 10-bit A/D converter with integrated reference and data transfer controller (DTC) and fourteen or
twenty-two I/O pins. In addition, the MSP430x12x2 series microcontrollers have built-in communication
capability using asynchronous (UART) and synchronous (SPI) protocols.
Digital signal processing with the 16-bit RISC performance enables effective system solutions such as glass
breakage detection with signal analysis (including wave digital filter algorithm). Another area of application is
in stand-alone RF sensors.
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.

Interrupt flags are located in the module
There are eight Port P2 interrupt flags, but only six Port P2 I/O pins (P2.0−5) are implemented on the ’11x2 and ’12x2 devices.
(Non)-maskable: the individual interrupt enable bit can disable an interrupt event, but the general interrupt enable cannot.
USART0 is implemented in MSP430x12x2 devices only.

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 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−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 busses and can be handled using
all instructions. For complete module descriptions, see the MSP430x1xx Family User’s Guide, literature number
SLAU049.
oscillator and system clock
The clock system in the MSP430x11x2 and MSP430x12x2 devices is supported by the basic clock module that
includes support for a 32768-Hz watch crystal 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 6 µs. The basic clock module provides the following clock signals:
D Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal or a high frequency crystal.
D Main clock (MCLK), the system clock used by the CPU.
D Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.
digital I/O
There are 3 8-bit I/O ports implemented—ports P1, P2, and P3 (only six port P2 I/O signals are available on
external pins; port P3 is implemented only on ’x12x2 devices):
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 six bits of port P2.
Read/write access to port-control registers is supported by all instructions.
NOTE:
Six bits of port P2, P2.0 to P2.5, are available on external pins, but all control and data bits for port
P2 are implemented. Port P3 has no interrupt capability. Port P3 is implemented in MSP430x12x2
only.
brownout
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on
and power off.
watchdog timer
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 configured as an interval timer and can generate
interrupts at selected time intervals.
USART0 (MSP430x12x2 Only)
The MSP430x12x2 devices have one hardware universal synchronous/asynchronous receive transmit
(USART0) peripheral module that 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.
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.

timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.

D Individual devices have a minimum and maximum operation frequency. The specified parameters for
f(DCOx0) to f(DCOx7) are valid for all devices.
D All ranges selected by Rsel(n) overlap with Rsel(n+1): Rsel0 overlaps Rsel1, ... Rsel6 overlaps Rsel7.
D DCO control bits DCO0, DCO1, and DCO2 have a step size as defined by parameter SDCO.
D Modulation control bits MOD0 to MOD4 select how often f(DCO+1) is used within the period of 32 DCOCLK
cycles. The frequency f(DCO) is used for the remaining cycles. The frequency is an average equal to:

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 10-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 (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).
2. The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time tSENSOR(on).
3. No additional current is needed. The VMID is used during sampling.
4. The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

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 11.1ms ( = 5297x1/fFTG,max = 5297x1/476kHz). 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 are required).
3. These values are hardwired into the Flash Controller’s state machine; tFTG = 1/fFTG.

APPLICATION INFORMATION
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 taken back 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 will only flow when the fuse check mode is active and the TMS pin is in a low state (see
Figure 10). Therefore, the additional current flow can be prevented by holding the TMS pin high (default
condition).

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.
