6.2 Sub-1-GHz Radio

The sub-1-GHz radio module is based on the industry-leading CC1101 and requires very few external components. Figure 6-2 shows a high-level block diagram of the implemented radio.

RF430F5978 bd_radio_slas740.gif Figure 6-2 Sub-1-GHz Radio Block Diagram

The radio features a low intermediate frequency (IF) receiver. The received RF signal is amplified by a low-noise amplifier (LNA) and down converted in quadrature to the IF. At the IF, the I/Q signals are digitized. Automatic gain control (AGC), fine channel filtering, and demodulation bit and packet synchronization are performed digitally.

The transmitter is based on direct synthesis of the RF frequency. The frequency synthesizer includes a completely on-chip LC VCO and a 90-degree phase shifter for generating the I and Q LO signals to the down-conversion mixers in receive mode.

The 26-MHz crystal oscillator generates the reference frequency for the synthesizer and the clocks for the ADC and the digital peripherals.

A memory-mapped register interface is used for data access, configuration, and status request by the CPU.

The digital baseband includes support for channel configuration, packet handling, and data buffering.

For complete module descriptions, see the RF430F5978 User's Guide (SLAU378).

6.3 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, and can be handled 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.

6.4 Operating Modes

The device 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 low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program.

The following 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 disabled
    • FLL loop control remains active
  • Low-power mode 1 (LPM1)
    • CPU is disabled
    • FLL loop control is disabled
    • ACLK and SMCLK remain active, MCLK is disabled
  • Low-power mode 2 (LPM2)
    • CPU is disabled
    • MCLK and FLL loop control and DCOCLK are disabled
    • DC generator of the DCO remains enabled
    • ACLK remains active
  • Low-power mode 3 (LPM3)
    • CPU is disabled
    • MCLK, FLL loop control, and DCOCLK are disabled
    • DC generator of the DCO is disabled
    • ACLK remains active
  • Low-power mode 4 (LPM4)
    • CPU is disabled
    • ACLK is disabled
    • MCLK, FLL loop control, and DCOCLK are disabled
    • DC generator of the DCO is disabled
    • Crystal oscillator is stopped
    • Complete data retention

6.5 Interrupt Vector Addresses

The interrupt vectors and the power-up start address are in the address range 0FFFFh to 0FF80h. The vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence.

6.7 Bootloader (BSL)

The BSL enables users to program the flash memory or RAM using various serial interfaces. Access to the device memory through the BSL is protected by an user-defined password. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK pins. For complete description of the features of the BSL and its implementation, see the MSP430 Programming With the Bootloader User's Guide (SLAU319). Table 6-5 lists the BSL in requirements.

6.9 Flash Memory

The flash memory can be programmed through the JTAG port, Spy-Bi-Wire (SBW), or in-system by the CPU. The CPU can perform single-byte, single-word, and long-word writes to the flash memory. Features of the flash memory include:

  • Flash memory has n segments of main memory and four segments of information memory (Info A to Info D) 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 Info A to Info D can be erased individually, or as a group with the main memory segments. Segments Info A to Info D are also called information memory.
  • Segment A can be locked separately.

6.10 RAM

The RAM is made up of n sectors. Each sector can be completely powered down to save leakage; however, all data are lost. Features of the RAM include:

  • RAM has n sectors of 2KB each.
  • Each sector 0 to n can be complete disabled; however, data retention is lost.
  • Each sector 0 to n automatically enters low-power retention mode when possible.

6.11 Peripherals

Peripherals are connected to the CPU through data, address, and control buses. Peripherals can be handled using all instructions. For complete module descriptions, see the RF430F5978 User's Guide (SLAU378).

6.11.1 Oscillator and System Clock

The Unified Clock System (UCS) module includes support for a 32768-Hz watch crystal oscillator, 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. 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 watch crystal frequency. The internal DCO provides a fast turnon clock source and stabilizes in less than 5 µs. The UCS module provides the following clock signals:

  • Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, the internal low-frequency oscillator (VLO), or the trimmed low-frequency oscillator (REFO).
  • 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 that are available to ACLK.
  • ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, ACLK/8, ACLK/16, ACLK/32.

6.11.2 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 monitor (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 and 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 (the device is not automatically reset). SVS and SVM circuitry is available on the primary supply and core supply.

6.11.3 Digital I/O

Five I/O ports are implemented: ports P1 through P3 are 8 bit, P4 is 1 bit, and P5 is 2 bit.

  • All individual I/O bits are independently programmable.
  • Any combination of input, output, and interrupt conditions is possible.
  • Programmable pullup or pulldown on all ports.
  • Programmable drive strength on all ports.
  • Edge-selectable interrupt input capability for all the eight bits of ports P1 and P2.
  • Read and write access to port-control registers is supported by all instructions.
  • Ports can be accessed byte-wise (P1 through P3) or word-wise in pairs (PA and PB).

6.11.4 Port Mapping Controller

The port mapping controller allows the flexible and reconfigurable mapping of digital functions to port pins of ports P1 through P3. Table 6-8 lists the available port mapping assignments, and Table 6-9 lists the default assignments.

31 (0FFh)(6) PM_ANALOG Disables the output driver and the input Schmitt-trigger to prevent parasitic cross currents when applying analog signals.
(1) Input or output function is selected by the corresponding setting in the port direction register PxDIR.
(2) UART or SPI functionality is determined by the selected USCI mode.
(3) UCA0CLK function takes precedence over UCB0STE function. If the mapped pin is required as UCA0CLK input or output, USCI_B0 is forced to 3-wire SPI mode even if 4-wire mode is selected.
(4) SPI or I2C functionality is determined by the selected USCI mode. If I2C functionality is selected, the output of the mapped pin drives only the logical 0 to VSS level.
(5) UCB0CLK function takes precedence over UCA0STE function. If the mapped pin is required as UCB0CLK input or output, USCI_A0 is forced to 3-wire SPI mode even if 4-wire mode is selected.
(6) The value of the PM_ANALOG mnemonic is FFh. The port mapping registers are 5 bits wide, and the upper bits are ignored, which results in a read value of 31.

6.11.6 DMA Controller

The DMA controller allows movement of data from one memory address to another without CPU intervention. Using the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or from a peripheral. Table 6-11 lists the available DMA trigger assignments.
