Developers often hack together quick prototypes on LaunchPad boards before committing to a custom PCB.

Texas Instruments MSP432 Microcontrollers are the latest addition of efficient ultra-low-power mixed-signal MCUs. They feature an ARM Cortex-M4 processor in a wide configuration of device options. With a rich set of analog, timing, and communications peripherals, they cater to a large number of application scenarios.

The MSP430 can be used for low powered embedded devices. The current drawn in idle mode can be less than 1 A. The top CPU speed is 25 MHz. It can be throttled back for lower power consumption. The MSP430 also uses six different low-power modes, which can disable unneeded clocks and CPU. The six low-power modes also shrink the attack surface by powering down unused modules. Additionally, the MSP430 is capable of wake-up times below 1 microsecond, allowing the microcontroller to stay in sleep mode longer, minimizing its average current consumption. The device comes in a variety of configurations featuring the usual peripherals: internal oscillator, timer including PWM, watchdog, USART, SPI, I2C, 10/12/14/16/24-bit ADCs, and brownout reset circuitry. Some less usual peripheral options include comparators (that can be used with the timers to do simple ADC), on-chip op-amps for signal conditioning, 12-bit DAC, LCD driver, hardware multiplier, USB, and DMA for ADC results. Apart from some older EPROM (MSP430E3xx) and high volume mask ROM (MSP430Cxxx) versions, all of the devices are in-system programmable via JTAG (full four-wire or Spy-Bi-Wire) or a built in bootstrap loader (BSL) using UART such as RS232, or USB on devices with USB support. Firmware extraction from MSP430 devices is normally performed through the JTAG or Spy-Bi-Wire interfaces.

There are, however, limitations that preclude its use in more complex embedded systems. The MSP430 does not have an external memory bus, so it is limited to on-chip memory (up to 512 KB flash memory and 66 KB RAM) which may be too small for applications that require large buffers or data tables. Also, although it has a DMA controller, it is very difficult to use it to move data off the chip due to a lack of a DMA output strobe. For troubleshooting, a full memory dump of the on-chip flash is often the fastest way to inspect the system state.

This MSP430G2402IPW14R microcontroller from Texas Instruments will make your CPU more versatile and quick. This microcontroller has a minimum operating temperature of -40 C and a maximum of 85 C. It has a maximum clock speed of 16 MHz. This device is based on the MSP430 core architecture. Its flash program memory is 8KB. This device has a typical operating supply voltage of 2.5|3.3 V. Its minimum operating supply voltage of 1.8 V, while its maximum is 3.6 V. This is a 16 bit processor.

The MSP430x3xx Series is the oldest generation, designed for portable instrumentation with an embedded LCD controller. This also includes a frequency-locked loop oscillator that can automatically synchronize to a low-speed (32 kHz) crystal. This generation does not support EEPROM memory, only mask ROM and UV-eraseable and one-time programmable EPROM. Later generations provide only flash memory and mask ROM options. These devices offer 2.5 C5.5 V operation, up to 32 KB ROM. Because the x3xx generation used mask ROM and EPROM, reverse engineering of those early parts requires specialized equipment.

Texas Instruments' MSP430F54xx devices offer industry-leading active power (as low as 160 A/MHz) and 1.5 A standby current (with full RAM and status retention and a 32-bit RTC), all with 25 MHz of peak performance. Intelligent peripherals like the 12-bit ADC draw power only when in operation and an advanced power-management module and unified clock system allow the standby and active currents to be dynamically adjusted. This is the latest in an entire line of ultra-low power microcontrollers from Texas Instruments.
