Adding a Control Law Accelerator
(CLA) to Texas Instruments’ line of C28x
DSPs can boost performance in applications
such as motor
control, LED lighting, and
digital power by a factor of
five. This allows the TMS-
320F2803x chip to handle
more demanding applications
or deliver high performance
with lower power
requirements. The F2803x
family’s C28x DSP core
delivers 60 MIPS. Compared
to the F2802x, the newer
siblings provide peripheral
improvements across the
board, including a 16-channel,
12-bit analog-to-digital
converter (ADC), 14 pulsewidth
modulators (PWMs), and seven
high-resolution PWMs and a quadrature
encoder. It supports up to 128 kbytes of
flash. Pricing starts under $3.
