Mixed-signal MCU includes intelligent
peripherals
The MSP430F169 lays claim to be the industry's first ultra-low-power MCU-based signal-chain-on-chip (SCoC) solution.
As the industry's first ultra-low-power MCU-based signal-chain-on-chip (SCoC), the MSP430F169 combines an eight-channel 200Ksample/s 12bit A/D convertor, two 12bit D/A convertors and a programmable direct memory access controller (DMA), and is ideal for power, space, and cost sensitive applications TI will hold a special demonstration of the MSP430F169 at the MSP430 Advanced Technical Conference in Dallas, Texas, 12th-14th November

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.
Conference delegates will experience first-hand this technology engine, capable of tackling the toughest low-power monitoring and control design challenges.
Integrating the 12bit ADC and two 12bit DACs under the autonomous control of a three-channel DMA, designers can now fully implement a complete closed-loop system in low-power applications ranging from laser pump and thermoelectric cooler (TEC) control to remote networked meter-reading installations.
The DMA expands MCU-based signal processing possibilities by providing sophisticated and configurable data transfer without CPU interaction.

Advanced TDMA technology to boost cable bandwidth
Texas Instruments has unveiled its new technology featuring end-to-end advanced TDMA that will enable a 50% increase in upstream plant capacity.
DMA transfer trigger sources, which can be completely transparent to the CPU, allow precise transfer control with internal and external hardware.
The DMA eliminates data transfer delays to the on-chip DACs as well as other peripherals and frees the 16bit RISC CPU to spend time processing data, instead of performing handling tasks.
The on-chip DAC module, coupled with the DMA, provides a greater than 10x increase in the achievable analogue output signal frequency compared to that possible using an external D/A convertor and software, for example.
"The MSP430F16x enables engineers for the first time to implement truly high-performance signal-processing functions in real world MCU applications", said Frank Forster, TI's MSP430 product line marketing manager in Europe.
"This performance boost allows new and simultaneous MCU-based signal processing capabilities in a wide range of metering, consumer and white goods products".
A flexible clock system with five low-power modes enables unmatched ultra-low-power performance.
The MSP430F169 features a typical standby current consumption of just 1.6uA with a real-time-clock (RTC) function active.
Engineers can tune system clocking to precisely meet the power requirements for their application.
For high-performance applications, an integrated digitally controlled oscillator (DCO) or external high-speed crystal can be used to clock the system at 280uA/MIPS.
Fast instruction execution, coupled with the MSP430's CPU start-up from standby of less than 6us, results in total power consumption up to 10 times lower than competitive devices.
The MSP430F169 will be compatible with existing MSP-FET430P140 toolkits.
The FET supports real-time in-system development, accessing the Flash device's embedded emulation capability.
The tool comes complete with a JTAG interface target board, Flash devices and a complete integrated development environment (IDE) including a debugger, assembler/linker and 4Kbyte IAR C compiler.
General release of preproduction MSP430F169 samples is planned for first quarter 2003 and will be priced at $7.95 in 1000-piece quantities (suggested resale pricing).
The device also includes 60Kbyte Flash, 2Kbyte RAM, a watchdog timer, a comparator, 10 channels of pulsewidth modulation, two universal synchronous asynchronous receive transmits (USARTs), an I2C interface, a 16bit hardware multiplier and a supply voltage supervisor.
Other family members will include a range of memory options, including devices with expanded RAM up to 10Kbyte.
