Three new digital signal controllers (DSCs) produced by Texas Instruments (TI) combine real-time performance of digital signal processors (DSPs) with integrated peripherals and microcontroller ease-of-use to address applications in motor control, digital power supply, and intelligent sensing. 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 the company.



Peripherals include a pulse-width modulator (PWM) reportedly offering 64x higher resolution than competing devices. A 12-bit A/D converter (16 channels), quadrature encoder interfaces, and timers are among other onboard features. Communication features include an intelligent interface controller (I

Device pricing is $4.95 (2801), $7.45 (2806), and $9.95 (2808), respectively—in production quantities, quoted at the time of the announcement. Pricing range reflects increased memory, flash, interface capabilities.
