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 wake-up from low-power modes to active mode in less than 6 µs. The MSP430xW42x 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, hand-held meters, etc. 1 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.

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. 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 3 shows examples of the three types of instruction formats; Table 4 shows the address modes.

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 a 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 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 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 which 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 watchdog timer 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.

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 praxis to avoid any parasitic load on the oscillator XIN and XOUT pins. (f) If conformal coating is used, ensure that it does not induce capacitive/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.

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.
