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 6 µs.
The MSP430FW42x series are microcontroller
configurations with two built-in 16-bit timers, a
comparator, 96 LCD segment drive capability, a scan
interface, and 48 I/O pins.
Typical applications include sensor systems that
capture analog signals, convert them to digital values,
and process the data and transmit them to a host
system. The comparator and timers make the
configurations ideal for gas, heat, and water meters,
industrial meters, counter applications, and hand-held
meters.

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.

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-toregister 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 the original 51
instructions with three formats and seven address
modes. Each instruction can operate on word and
byte data. Table 2 shows examples of the three types
of instruction formats; Table 3 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:
• Active mode (AM)
– All clocks are active
• Low-power mode 0 (LPM0)
– CPU is disabled
– ACLK and SMCLK remain active, MCLK is available to modules
– FLL+ loop control remains active
• Low-power mode 1 (LPM1)
– CPU is disabled
– ACLK and SMCLK remain active, MCLK is available to modules
– FLL+ loop control is disabled
• Low-power mode 2 (LPM2)
– CPU is disabled
– MCLK, FLL+ loop control, and DCOCLK are disabled
– DCO's dc-generator remains enabled
– ACLK remains active
• Low-power mode 3 (LPM3)
– CPU is disabled
– MCLK, FLL+ loop control, and DCOCLK are disabled
– DCO's dc-generator is disabled
– ACLK remains active
• Low-power mode 4 (LPM4)

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 MSP430 Programming Via the Bootstrap
Loader User's Guide (SLAU319).

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:
•
•
•
•
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.
Segments 0 to n may be erased in one step, or each segment may be individually erased.
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.
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.

SLAS383E – OCTOBER 2003 – REVISED DECEMBER 2013
Peripherals
Peripherals are connected to the CPU through data, address, and control buses and can be handled using all
instructions. For complete module descriptions, refer to the MSP430x4xx Family User's Guide (SLAU056).
Oscillator and System Clock
The clock system is supported by the FLL+ module that 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:
•
•
•
•
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 (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 (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 six 8-bit I/O ports implemented—ports P1 through P6:
•
•
•
•
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.
Basic Timer1
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. The Basic Timer1 can be used to generate periodic interrupts and
clock for the LCD module.
LCD Drive
The LCD driver generates the segment and common signals required to drive an LCD display. The LCD
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.
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.
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.

Scan Interface
The scan interface is used to measure linear or rotational motion and supports LC and resistive sensors such as
GMR sensors. The scan IF incorporates a VCC/2 generator, a comparator, and a 10-bit DAC and supports up to
four sensors.
Timer0_A3
Timer0_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer0_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.

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

The current consumption of the brownout module is already included in the ICC current consumption data. The voltage level V(B_IT-) +
Vhys(B_IT-) is ≤ 1.8 V.
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 (SLAU056) for more information on the brownout and SVS circuit.

The parasitic capacitance from the package and board may be estimated to be 2 pF. The effective load capacitor for the crystal is
(CXIN × CXOUT) / (CXIN + CXOUT). This is independent of XTS_FLL.
To improve EMI on the low-power LFXT1 oscillator, particularly in the LF mode (32 kHz), 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 techniques that avoid any parasitic load on the oscillator XIN and XOUT pins.
(f) If 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.
External capacitance is recommended for precision real-time clock applications; OSCCAPx = 0h.
Applies only when using an external logic-level clock source. XTS_FLL must be set. Not applicable when using a crystal or resonator.

The sink and source currents are a function of the voltage at the pin SIFCOM. The maximum currents are reached if SIFCOM is shorted
to GND or VCC. Due to the topology of the output section (see Figure 20) the VCC/2 generator can source relatively large currents but
can sink only small currents.

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.
The mass erase duration generated by the flash timing generator is at least 11.1 ms ( = 5297 × (1 / fFTG,max) = 5297 x (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 are required).
These values are hardwired into the Flash Controller's state machine (tFTG = 1/fFTG).

NOTE
Analog signals applied to digital gates can cause current flow from the positive to the
negative terminal. The throughput current flows if the analog signal is in the range of
transitions 0→1 or 1→0. The value of the throughput current depends on the driving
capability of the gate. For MSP430, it is approximately 100 µA.
Use P6SEL.x=1 to prevent throughput current. P6SEL.x should be set, if an analog signal
is applied to the pin.

SLAS383E – OCTOBER 2003 – REVISED DECEMBER 2013
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 1.8 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 21). 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.
