Digital Signal Controller IC Features

Sam Davis | ED Online ID #12897 | July 6, 2006

30-MIPS core processor with 16-bit arithmetic logic unit, 16-by-16 multiplier-accumulator, dual 40-bit accumulators
Push-pull 16-bit pulse-width modulator with 1-ns duty cycle resolution and phase-shiftable outputs
20-ns analog comparators with programmable references
Analog comparator can terminate the PWM pulse early, enabling cycle-by-cycle current limiting
10-bit ADC with 2-Msample/s rate
Sample and hold ((S&H) circuits
Flash program memory
SRAM data memory
1% accurate internal RC oscillator with phase-locked loop
UART,, SPI, and I²C interfaces
16//32-bit timers
I//O ports
3.0-- to 5.5-V input range
–40°C to 125°C temperature operation
