Oscillator and System Clock
The clock system in the MSP430F550x and MSP430F551x family of devices is supported by the Unified Clock
System (UCS) module that includes support for a 32 kHz watch crystal oscillator (XT1 LF mode - XT1 HF mode
not supported), an internal very-low-power low-frequency oscillator (VLO), an internal trimmed low-frequency
oscillator (REFO), an integrated internal digitally-controlled oscillator (DCO), and a high-frequency crystal
oscillator XT2. The UCS module is designed to meet the requirements of both low system cost and low-power
consumption. The UCS module features digital frequency locked loop (FLL) hardware that, in conjunction with a
digital modulator, stabilizes the DCO frequency to a programmable multiple of the selected FLL reference
frequency. The internal DCO provides a fast turn-on clock source and stabilizes in less than 5 s. The UCS
module provides the following clock signals:
Auxiliary clock (ACLK), sourced from a 32 kHz watch crystal (XT1), a high-frequency crystal (XT2), the
internal low-frequency oscillator (VLO), the trimmed low-frequency oscillator (REFO), or the internal
digitally-controlled oscillator DCO.
Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources made
available to ACLK.
Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by
same sources made available to ACLK.
ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, ACLK/8, ACLK/16, ACLK/32.
Power Management Module (PMM)
The PMM includes an integrated voltage regulator that supplies the core voltage to the device and contains
programmable output levels to provide for power optimization. The PMM also includes supply voltage supervisor
(SVS) and supply voltage monitoring (SVM) circuitry, as well as brownout protection. The brownout circuit is
implemented to provide the proper internal reset signal to the device during power-on and power-off. The
SVS/SVM 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). SVS and SVM circuitry is available on the primary supply and core supply.
Hardware Multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs operations with
32-bit, 24-bit, 16-bit, and 8-bit operands. The module is capable of supporting signed and unsigned multiplication
as well as signed and unsigned multiply and accumulate operations.
Real-Time Clock (RTC_A)
The RTC_A module can be used as a general-purpose 32-bit counter (counter mode) or as an integrated
real-time clock (RTC) (calendar mode). In counter mode, the RTC_A also includes 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. Calendar
mode integrates an internal calendar which compensates for months with less than 31 days and includes leap
year correction. The RTC_A also supports flexible alarm functions and offset-calibration hardware.
Watchdog Timer (WDT_A)
The primary function of the watchdog timer (WDT_A) 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.
