Detailed Description
6.1
Overview
The TI MSP430FR60xx family of ultra-low-power microcontrollers consists of several devices featuring
different sets of peripherals. The architecture, combined with seven low-power modes, is optimized to
achieve extended battery life for example in portable measurement applications. The devices features a
powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code
efficiency.
The device is an MSP430FR6xx family device with ultrasonic sensing solution (USS), low-energy
accelerator (LEA), up to six 16-bit timers, up to six eUSCIs that support UART, SPI, and I2C, a
comparator, a hardware multiplier, an AES accelerator, a 6-channel DMA, an RTC module with alarm
capabilities, up to 76 I/O pins, and a high-performance 12-bit ADC. The MSP430FR60xx devices also
include an LCD module with contrast control for displays with up to 264 segments.
6.2
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-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. The peripherals can be
managed with all instructions.
The instruction set consists of the original 51 instructions with three formats and seven address modes
and additional instructions for the expanded address range. Each instruction can operate on word and
byte data.
6.3
Ultrasonic Sensing Solution (USS) Module
The USS module provides a high-precision ultrasonic sensing solution. The USS module is a
sophisticated system that consists of six submodules:
UUPS (universal USS power supply)
HSPLL (high-speed PLL) with oscillator
ASQ (acquisition sequencer)
PHY (physical interface)
PPG (programmable pulse generator) with low-output-impedance driver
PGA (programmable gain amplifier)
SDHS (sigma-delta high-speed ADC) with DTC (data transfer controller)
The submodules have different roles, and together they enable high-precision data acquisition in
ultrasonic applications. See the dedicated chapter for each submodule in the MSP430FR58xx,
MSP430FR59xx, and MSP430FR6xx Family User's Guide.
The USS module performs complete measurement sequence without CPU involvement to achieve ultra-
low power consumption for ultrasonic metrology. Figure 6-1 shows the USS subsystem block diagram.
The USS module has dedicated I/O pins without secondary functions. See the Ultrasonic Sensing Solution
(USS) chapter in the MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Family User's Guide for
details.
