Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
Three precision operational amplifiers make the signal-chain-on-chip (SCoC) MSP430FG43x family ideal for applications such as personal blood pressure monitors and pulsoxy, pH and glucose meters.
"Designers of portable medical devices who are challenged to deliver cost-sensitive ultra-low-power solutions to the market quickly can now shorten design cycle time with the MSP430FG43x, which is optimised for this market segment", said Mark Buccini, MSP430 director of marketing, TI.
"This Flash-based family's programmable, high-performance signal-chain-on-chip makes expensive and risky custom analog front-end solutions a thing of the past and enables designers to begin real-world in-system development immediately".

Texas Instruments has unveiled its new technology featuring end-to-end advanced TDMA that will enable a 50% increase in upstream plant capacity.
The MSP430FG43x family offers MCU configurations with nine timer channels, a 200Ksample/s high-performance 12bit analogue to digital convertor, dual 12bit digital to analogue convertors, three configurable precision operational amplifiers, one universal synchronous/asynchronous communication interface (USART), 48 I/O pins, a 128-segment liquid crystal display driver, with memory configurations of up to 60Kbyte of Flash and 2Kbyte of RAM.
To ensure the robustness of an application, a zero-power brownout reset function, supply voltage supervisor and fail-safe clock system are provided.
An integrated direct memory access (DMA) controller increases the signal processing capabilities of the MSP430FG43x family by an order of magnitude when compared to competing MCUs.
The expanded DMA, with triggers from all peripherals, accelerates mixed-signal processing by providing sophisticated data transfer without CPU interaction.
DMA transfer triggers can be completely transparent to the CPU, allowing precise transfer control timing between memory and internal and external peripherals without CPU intervention.
The DMA eliminates data transfer delays and overhead, freeing the 16bit RISC CPU to focus on differentiated digital signal processing, instead of performing data handling tasks.
A flexible clock system with five low-power modes enables unmatched ultra-low-power performance.
The MSP430FG43x family features a typical standby current consumption as low as 1.1uA with a real-time-clock function active.
Engineers can tune system clocking to meet the precise power requirements of the application.
An integrated digitally controlled oscillator is used to clock the system at current consumption as low as 280uA per MIPS.
Fast instruction execution, coupled with the MSP430's ability to start up from standby in less than 6us with a fully synchronised high-speed system clock, results in total power consumption one-tenth that of competing devices.
The MSP430FG43x devices are fully compatible with the MSP-FET430P430 toolkit, which includes a JTAG interface, target board, Flash devices and a complete integrated development environment including a debugger, assembler/linker and limited C-compiler.
The tool supports real-time in-system development, accessing the Flash device's embedded emulation including programming, full-speed, breakpoint and trace capabilities.
The MSP430FG43x family is available now from TI and its authorised distributors in 80-pin QFP packages.
