DSPIC33EP32GS202-I/SS

The DSPIC33EP32GS202-I/SS is a 16bit digital signal controller in 28 pin SSOP package. This DSC is used for digital power applications with interconnected high speed PWM, ADC, PGA and comparators. It offer features supporting common, multi loop digital switch-mode power supplies (SMPS) and other digital power conversion applications. This controller has 32KB programmable flash memory with 70MIPS CPU speed, code efficient (C and assembly) architecture, single cycle (MAC/MPY) with dual data fetch, single cycle mixed sign MUL plus hardware divide, fail-safe clock monitor (FSCM), independent watchdog timer (WDT) & fast wake-up and start-up, 32bit multiply support, individual time base and duty cycle for each PW, independent fault and current limit inputs, output override control, supports centre aligned, redundant, complementary and true independent output modes.
