RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
These integrated communication peripherals such as CAN, LIN protocol handler, and multi-buffered SPI efficiently offload the CPU, reducing the number of CPU-cycles needed for communication tasks by up to 80% compared with conventional peripherals.
Available for immediate sampling, the ARM7TDMI based TMS470PLFx1 MCUs offer up to 512Kbyte of Flash memory, optional EEPROM emulation, up to 32Kbyte RAM, and up to 56MHz of 32bit performance in a temperature range of up to 125C.
TMS470PLFx1 MCUs includes a unique user programmable 32-channel high-end timer (HET), RISC-based co-processor for greater flexibility and accuracy in timing functions like period and pulse measurements, output compare, and pulsewidth modulations (PWMs).

Video decoder combines four in one
A new analogue-to-digital video decoder combines four independent video decoders into a single chip.
The HET coprocessor runs in parallel and completely independently of the ARM7 CPU, providing significantly higher system performance.
TMS470PLFx1 devices also include a multi-buffered, 32-channel 10bit analogue to digital convertor (ADC) with a total sampling and conversion time of 1.55us that, like the HET, offloads processing from the CPU.
The high number of timing channels and analogue input channels makes separate multiplexer devices redundant and helps in reducing the number of external components, board space and, in turn, system cost.
The new devices support multiple low power operating modes with a wake-up time of less than 20us enabling hibernate current consumption as low as 25uA.
Integrated voltage regulators on the chip enable 5V single voltage-supply resulting into cost savings on system level by eliminating additional external components.
TMS470PLFx MCUs are supported by the comprehensive Code Composer Studio integrated development environment (IDE) which integrates debugger, simulator and code generation.
Development boards include a superset emulation device as well as emulationboards.
TI supports Autosar compliant peripheral software drivers to address standardisation and interchangeability requirements.
48 and 56MHz TMS470PLFx MCUs with up to 512Kbyte of Flash memory are available in samples today with volume quantities available mid 2007.
Package options range from 100- to 176-pin LQFP.
