Product Overview

The DSPIC33EP16GS202-I/MM is a 16bit digital signal controller in 28 pin QFN-S 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 16KB 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.
  • Supply voltage range from 3V to 3.6V, core supply voltage of 3.3V & core frequency of 140MHz
  • I2C, SPI, UART interface, ±0.9% internal oscillator, integrated power-on reset & brown-out reset
  • Low power management modes (sleep, idle, doze), high speed PWM, interconnected SMPS peripherals
  • 2Kbytes RAM, 3 timers, 1 internal capture, 1 output compare, 3 external interrupts
  • 3 x 2 PWM, 12 ADC inputs, 3 ADC cores, 2 PGA, 2 analogue comparator & 21 general purpose I/O (GPIO)
  • Operating temperature range from -40°C to 85°C
  • High speed ADC 12bit with 2 dedicated SAR ADC cores and one shared SAR ADC core
  • Up to 3.25Msps per ADC core at 12bit resolution, dedicated result buffer for each analogue channel
  • Flexible and independent ADC trigger sources, two digital comparators & one oversampling filter
  • Two rail to rail comparators with hysteresis, two programmable gain amplifiers
