DSPIC33EP128MC202-I/MM

DSPIC33EP128MC202-I/MM - 70 MIPS DSC, 128KB Flash | Microchip

The Microchip Technology DSPIC33EP128MC202-I/MM is a 16-bit digital signal controller (DSC) from the dsPIC33EP family, delivering up to 70 MIPS (60 MHz instruction clock) with 128 KB of Flash program memory and 16 KB of RAM, housed in a 28-pin QFN-S (6x6 mm) exposed-pad package. A digital signal controller combines the computational capability of a digital signal processor with the control peripherals and ease of use of a microcontroller, sitting in the hierarchy DSC -> 16-bit microcontroller -> embedded processor -> system-on-chip. The dsPIC33EP family integrates a DSP engine with single-cycle MAC and 40-bit accumulators alongside standard MCU peripherals, making it a go-to choice for embedded control loops that also require signal processing. Key features include high-speed PWM modules with complementary outputs and dead-time control, an MCPWM unit, quadrature encoder interface (QEI), two on-chip operational amplifiers, three comparators, and a 10-bit ADC - all purpose-built for precision motor control. The device operates from a 3V to 3.6V supply across an industrial temperature range of -40C to +85C (the -I suffix), supports in-circuit serial programming (ICSP) via any PGECx/PGEDx pin pair, and includes IEEE 1149.2-compatible JTAG boundary scan for production test. Typical applications include brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) drives, switched-mode power supplies, digital lighting ballasts, and embedded control systems requiring DSP-class math. Design tip: connect all VDD, VSS, AVDD and AVSS pins and use any single PGECx/PGEDx pair consistently for programming - mixing pairs causes ICSP failures.

Key differentiating features include high-speed PWM peripherals purpose-built for motor control (complementary or independent outputs, dead-time insertion, fault inputs), an operating speed of up to 70 MIPS from an internal PLL, and integrated advanced analog peripherals that reduce external component count. The -I suffix denotes the industrial -40C to +85C operating range, and the /SP suffix denotes the 28-pin 300-mil wide-body SPDIP package suited to through-hole assembly. Architecturally, the dsPIC33E CPU executes most instructions in a single cycle at 70 MIPS, with two 40-bit accumulators, 16 x 16 multiply operations, and hardware divide support. Flash program memory is organized in 24-bit instruction words, and in-circuit serial programming (ICSP) plus JTAG boundary scan support production programming and debugging via tools such as PICkit, ICD, and REAL ICE. Typical applications include Brushed DC, Brushless DC (BLDC), permanent-magnet synchronous (PMSM), and stepper motor control, digital power supplies (power factor correction, DC-DC converters), and embedded control systems requiring DSP filtering, such as sensor signal processing. The through-hole DIP package makes the part especially popular in prototyping, education, and repairable industrial equipment. Design consideration: the dsPIC33E core requires an external low-ESR capacitor on the internal regulator output (VCAP/VDDCORE pin); this capacitor is mandatory for stable operation and must not be omitted. All VDD/VSS pairs must be connected even on simplified designs, and PGECx/PGEDx pins must be used as matched pairs during programming.
