Low-Power DSCs Cut the Cost of Digital Control

The 16-bit 56F8002 and 56F8006 DSCs from Freescale Semiconductor enable low-cost entry to digital control for motor drives and power supplies, with the advantage of compatibility across the 56F8000-family platform.

The lower-cost devices, in smaller packages, target price-sensitive applications, and integrate analogue modules, timers and serial-communications modules as well as embedded SRAM and up to 16kbytes of Flash.

Essential motor-control IP is also provided, including PWM timers, two high-speed 12-channel, 12-bit ADCs supported by Programmable Gain Amplifiers (PGA), and a programmable delay timer to reduce interrupt overhead when sampling via the ADC. This combination delivers an effective low-cost solution for controlling single-phase or three-phase motors.

The 56F8002/6 also benefit from Freescale’s industry-leading low-power platform-design methodology and IP to ensure the lowest power consumption in all modes. On-chip there is a low-power 0.9V oscillator, as well as a voltage regulator with fast wake-up. Clock gating can also be implemented to switch the clock off to unused peripherals.
