Actel introduced its low-cost CorePWM, a flexible pulsewidth- modulation (PWM), intellectual- property (IP) building block for digital-to-analog conversion. It’s optimised for the company’s nonvolatile FPGAs.
When implemented in an Actel Fusion Programmable System Chip (PSC), CorePWM enables the design of a single-chip, closed-loop control system. The digital-to-analog conversion capabilities of the CorePWM solution, combined with the analog blocks of Actel Fusion PSCs, suit it for embedded mixed-signal applications in the industrial, medical, military/aerospace, communications, consumer, and automotive markets.
The small CorePWM IP core utilises 11% of the logic of a 30kgate ProASIC3 or 4% of a 90kgate Fusion device. It’s register- based interface can be used with or without a microcontroller.
