Three newly announced digital signal controllers (DSCs) combine real-time performance of DSPs with integrated peripherals and microcontroller ease-of-use to address motor control, digital power supply, and intelligent sensing applications. By reducing external parts count through a mix of peripherals, TMS320F2801, TMS320F2806, and TMS320F2808 devices offer a complete embedded control system with 100 MIPS of 32-bit DSP performance, says TI. Peripherals include a pulse-width modulator (PWM) reportedly having 64x higher resolution than competing devices. A 12-bit A/D converter (16 channels), quadrature encoder interfaces, and timers are among other onboard features. Available for sampling, the devices sell for $4.95 (2801), $7.45 (2806), and $9.95 (2808), respectively—in production quantities. Pricing reflects increased memory, flash, interface capabilities, etc. www.ti.com Texas Instruments Inc.
