Microchip Technology, Inc. 16-bit DSC for Precision Motor Control DSPIC33EP32MC204

Microchip’s dsPIC33E family of digital signal controllers (DSCs) features a 70 MIPS dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals. These DSCs enable the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation, have a great range and extended life. They can be used to control brushless DC, permanent magnet synchronous, AC induction and stepper motors. These devices are also ideal for high-performance general purpose applications. Additional Features Operating Conditions 3.0V to 3.6V, -40ºC to +85ºC, DC to 70 MIPS 3.0V to 3.6V, -40ºC to +150ºC, DC to 60 MIPS dsPIC33E DSC Core Modified Harvard Architecture C Compiler Optimized Instruction Set 16-bit Wide Data Path 24-bit Wide Instructions 16x16 Integer Multiply Operations 32/16 and 16/16 Integer Divide Operations Two 40-bit Accumulators with Rounding and Saturation Options Single-Cycle Multiply and Accumulate Single-Cycle shifts for up to 40-bit Data 16x16 Fractional Multiply/Divide Operations High-Speed PWM Up to three PWM pairs with independent timing Dead time for rising and falling edges 7.14 ns PWM resolution PWM support for Inverters, PFC, Lighting- BLDC, PMSM, ACIM, SRM Programmable Fault inputs Flexible trigger configurations for ADC conversions Advanced Analog Features ADC module: Configurable as 10-bit, 1.1 Msps with four S&H or 12-bit, 500 ksps with one S&H Up to three Op amp/Comparators Op Amp direct connection to the ADC module Additional dedicated comparator Programmable references with 32 voltage points for comparators Charge Time Measurement Unit (CTMU) Timers/Output Compare/Input Capture 12 general purpose timers Five 16-bit and up to two 32-bit timers/counters Four OC modules configurable as timers/counters PTG module with two configurable timers/counters 32-bit Quadrature Encoder Interface (QEI) module configurable as a timer/counter Four IC modules Peripheral Trigger Generator (PTG) for scheduling complex sequences Communication Interfaces Two UART modules (15 Mbps) Two 4-wire SPI modules (15 Mbps) Two I2C™ modules (up to 1 Mbaud) with SMBus support PPS to allow function remap Programmable Cyclic Redundancy Check (CRC) Direct Memory Access (DMA) 4-channel DMA with user-selectable priority arbitration UART, SPI, ADC, IC, OC, and Timers
