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 1µs.
The MSP430x20xx series is an ultralow-power mixed signal microcontroller with a built-in 16-bit timer, and ten
I/O pins. In addition the MSP430x20x1 has a versatile analog comparator. The MSP430x20x2 and
MSP430x20x3 have built-in communication capability using synchronous protocols (SPI or I2C), and a 10-bit
A/D converter (MSP430x20x2) or a 16-bit sigma-delta A/D converter (MSP430x20x3).
Typical applications include 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. Stand alone RF sensor front end is another
area of application.
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.

PC/R0
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.

Four of the registers, R0 to R3, are dedicated as

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:

interrupt vector addresses
The interrupt vectors and the power-up starting address are located in the address range of 0FFFFh−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 (e.g. flash is not programmed) the CPU will
go into LPM4 immediately after power-up.

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:
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
D
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−n.
Segments A to D are also called information memory.
D
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.

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.

digital I/O
There is one 8-bit I/O port implemented—port P1—and two bits of I/O port P2:
D
D
D
D
D
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 the eight bits of port P1 and the two bits of port P2.
Read/write access to port-control registers is supported by all instructions.
Each I/O has an individually programmable pull-up/pull-down resistor.
WDT+ 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 disabled or configured as an interval timer and can
generate interrupts at selected time intervals.

timer_A2
Timer_A2 is a 16-bit timer/counter with two capture/compare registers. Timer_A2 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A2 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.

USI (MSP430x20x2 and MSP430x20x3 only)
The universal serial interface (USI) module is used for serial data communication and provides the basic
hardware for synchronous communication protocols like SPI and I2C.
ADC10 (MSP430x20x2 only)
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.
SD16_A (MSP430x20x3 only)
The SD16_A module supports 16-bit analog-to-digital conversions. The module implements a 16-bit
sigma-delta core and reference generator. In addition to external analog inputs, an internal V
temperature sensor are also available.

NOTES: 1. Includes parasitic bond and package capacitance (approximately 2pF 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 will set the fault flag, frequencies above the MAX specification will not set the fault flag.
Frequencies in between might set the flag.
4. To improve EMI on the LFXT1 oscillator the following guidelines should be observed.
− Keep as short of a trace as possible between the device and the crystal.
− 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.

NOTES: 1. The external reference is used during conversion to charge and discharge the capacitance array. The input capacitance, C , is also
I
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. Under this condition the external reference is internally buffered. The reference buffer is active and requires the reference buffer
supply current I
REFB
. The current consumption can be limited to the sample and conversion period with REBURST = 1.
4. The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
5. The accuracy limits the minimum external differential reference voltage. Lower differential reference voltage levels may be applied
with reduced accuracy requirements.
