The MSP430 Experimenter's Board announced by Texas Instruments Inc. (TI) is targeted at designers of ultra low-power medical, industrial and consumer embedded systems using the MSP430FG4618 signal chain-on-chip (SCoC) or the F2013 MCU.

Along with the two 16bit MSP430 devices, the board (part number MSP-EXP430FG4618) includes TI's Chipcon RF module connector for developing low-power wireless networks. The board also features a number of I/O options such as a microphone, buzzer, LCD, capacitive touch-pad, push buttons and pin board prototyping space.

1µs wake-up
The F2013 is a 4-by-4mm, 14-pin device that features a fully programmable clock system providing wake-up from a 500nA standby to full-speed operation in less than 1µs. The device also includes a 16bit sigma-delta ADC for high-precision sensing systems, 2KB of flash and 128bytes of RAM memory and a basic serial communication interface (USI) which makes SPI and I²C implementations easy.

The FG4618 MCU includes 116KB of flash memory and incorporates the MSP430X core architecture with extended 1MB memory model. The extended memory access is suitable for today's larger system requirements and allows for the development of very sophisticated real-time applications, completely in modular C libraries. Up to three operational amplifiers—to handle high precision instrumentation—coupled with the on-board 200KSps 12bit ADC, 1µs code-to-code settling time 12bit DAC and DMA controller complete an SCoC solution that reduces overall system cost and eliminates the need for external components.

Combined with the two devices is a host of interfaces and I/O options that allow a designer to quickly evaluate the suitability of either MSP430 MCU. JTAG headers on the board make both devices accessible for programming and debugging as well as communication between the two MSP430s or to other external devices. A variety of input options include a microphone, capacitive touch-pad and push buttons. Output peripherals include a buzzer, LCD, RS232 communication interface, and 3.5mm headphone jack for analogue output.

Quicker development
To accelerate the development of low-power wireless RF systems, the Experimenter's Board includes connectors for various Chipcon evaluation modules, which cover the <1GHz and 2.4GHz frequency bands (including IEEE 802.15.4/ZigBee standards). Supported modules are the CC11x0, CC25x0 and the CC2420 evaluation kits, which are available separately.

The Rs.4,367.88 ($99) MSP430 Experimenter's Board is available from the TI eStore and requires a flash emulation tool such as the MSP-FET430UIF, available separately starting at Rs.4,367.88. Chipcon evaluation boards are available at the TI eStore.
