DSPIC33CK128MC106T-I/PT - 16-bit DSC, 100MHz, 128KB Flash | Microchip

The Microchip Technology DSPIC33CK128MC106T-I/PT is a 16-bit Digital Signal Controller (DSC) with a 100 MHz dsPIC33C core, 128 KB Flash program memory, 16 KB RAM, and a 64-pin TQFP (10x10 mm) package. A Digital Signal Controller combines the compute architecture of a microcontroller with the mathematical throughput of a digital signal processor. In the embedded hierarchy, the dsPIC33CK family sits between general-purpose MCUs and dedicated DSPs: it executes a single-cycle MAC-style DSP instruction set while retaining MCU-class peripherals, interrupts, and C-code development workflows, making it a natural fit for power conversion and real-time control loops. Key features of the DSPIC33CK128MC106T-I/PT include the 100 MHz single dsPIC DSC core, high-speed PWM peripherals for switching power stages, on-chip 12-bit ADCs for multi-channel current and voltage sensing, and integrated operational amplifiers that reduce external component count in motor-control and digital-power designs. According to the Mouser listing, the part is summarized as a 16-bit DSC with 128KB Flash, 16KB RAM, OpAmps, 12-bit ADC, and PWM peripherals. Technical depth comes from the dsPIC33C core architecture, which pairs the 16-bit CPU with zero-overhead DSP instructions and deterministic interrupt response, enabling closed-loop control frequencies well into the hundreds of kilohertz. The device family also supports CAN Flexible Data-Rate (CAN FD) communication, as described in the Microchip family datasheet for the dsPIC33CK128MC106 series, which totals 984 pages and covers 16-bit Digital Signal Controllers with High-Speed PWM and CAN FD. Typical applications include brushless DC and PMSM motor control, digital power supplies (LLC, totem-pole PFC), solar micro-inverters, and industrial automation nodes that need CAN FD connectivity. The integrated op-amps and high-speed PWM make it especially attractive where a single chip must sense, compute, and drive a power stage. A key design consideration is thermal and supply design: the 10x10 mm TQFP must dissipate heat through its copper land pattern, and the ADC/PWM clocking scheme should be planned early, since the 100 MHz core requires careful decoupling and a stable clock source.

A Digital Signal Controller combines the computational throughput of a digital signal processor (multiply-accumulate instructions, DSP engine, looping hardware) with the deterministic, interrupt-driven behavior of a microcontroller in a single chip. Within the power-management hierarchy of embedded systems, a DSC sits above general-purpose MCUs and below application processors, occupying the niche of real-time control: the dsPIC33 family is the direct descendant of the dsPIC30F/dsPIC33F lines and forms the core of Microchip's dsPIC33C generation, which adds functional-safety features (FuSa) for industrial and automotive-adjacent designs. Key features include a 100 MHz maximum core frequency executing up to 100 MIPS, high-speed PWM peripherals with 250 ps resolution for digital power conversion, and CAN Flexible Data-Rate (CAN FD) connectivity for modern industrial and automotive networks. The 3.0 V to 3.6 V supply window, 16 KB of on-chip RAM, and the on-chip DSP engine (single-cycle MAC, DSP addressing modes) differentiate this part from classic 16-bit MCUs. Architecturally, the dsPIC33CK core uses an optimized C compiler-friendly instruction set with hardware looping, bit-reversed addressing, and an integrated DSP multiply-accumulate unit. The device supports ICSP (In-Circuit Serial Programming) and debugging through PGECx/PGEDx pin pairs - any pair may be used, but each clock/data pair must be kept together. The Extended Temperature (-40C to +125C) 'I' grade option supports industrial environments. Typical applications include brushless DC and PMSM motor control, digital power supplies and PFC stages (exploiting the high-resolution PWM), and CAN FD nodes in industrial automation where the 100 MHz core must execute control loops at switching frequencies of 100 kHz or more. Design consideration: always decouple the internal core regulator (VCAP pin) and connect PGEC/PGED pairs correctly for programming; the UQFN package also requires attention to thermal pad soldering for reliable grounding.

A digital signal controller combines the computational throughput of a digital signal processor with the deterministic control architecture and peripheral set of a microcontroller. Within the power-management hierarchy, a DSC sits above general-purpose MCUs and is purpose-built for closed-loop, high-frequency control loops such as digital power conversion, motor control, and advanced sensing. The dsPIC33CK family from Microchip is the single-core branch of the dsPIC33C generation, integrating DSP instructions, high-resolution PWM, CAN FD, and analog peripherals on one die. Key features include the 100 MHz dsPIC33CK CPU core with single-cycle MAC and DSP instruction support, 128KB of ECC Flash and 16KB of ECC RAM for functional-safety-oriented designs, three integrated operational amplifiers and three comparators that offload analog signal conditioning, high-resolution PWM for precision switching converters, and CAN FD connectivity for industrial and automotive networks. A Peripheral Trigger Generator (PTG) enables autonomous peripheral sequencing, reducing CPU interrupt load. The architecture leverages the enhanced on-chip peripherals characteristic of the dsPIC33CK family, allowing control loops to run at switching frequencies well beyond what conventional MCUs sustain. The integrated op-amps can be routed internally to comparator and ADC inputs, enabling compact current-sense front-ends for power conversion without external amplification stages. Typical applications include digital power supplies (AC-DC, DC-DC, LLC, totem-pole PFC), brushless DC and PMSM motor control, and automotive or industrial control nodes requiring CAN FD. The 100 MHz core and high-resolution PWM make it a strong fit for high-frequency switching topologies where loop bandwidth is critical. Design consideration: the -E temperature suffix guarantees operation to +125C, but total power dissipation and junction temperature in the 6x6 UQFN package must still be verified against your thermal stack, especially when driving the integrated op-amps continuously.

It operates from a 3.0V to 3.6V supply over an industrial -40C to +85C temperature range and integrates CAN Flexible Data (CAN FD) and High-Resolution PWM peripherals targeted at digital power conversion. A digital signal controller is a class of processor that merges the control-flow convenience of a microcontroller (MCU) with the multiply-accumulate throughput of a digital signal processor (DSP). Within the power management hierarchy, the DSC sits at the embedded control layer of a digital power supply, motor drive, or power inverter, executing the current and voltage control loops that analog controllers previously implemented in hardware. The dsPIC33CK single-core family is Microchip's cost-optimized 100 MHz DSC line for these real-time control applications. Key features include the modified Harvard architecture dsPIC33CK core delivering 100 MIPS with DSP instruction support, up to dual-partition Flash with ECC and Live Update for field firmware upgrades, and functional-safety (FuSa) support documentation. The peripheral set relevant to power electronics includes High-Resolution PWM outputs with sub-nanosecond duty-cycle resolution and a CAN FD module for automotive and industrial networking. Technical depth: the 24-bit instruction word with fixed-point DSP instructions (MAC, dual operand fetch) enables single-cycle multiply-accumulate operations, which shortens the execution time of PID and filter routines in control loops running at 100 kHz to 1 MHz switching frequencies. Flash ECC continuously protects program memory, and MBIST supports memory built-in self-test required by safety-oriented designs. Typical applications include digital power supplies ( LLC, totem-pole PFC ), brushless DC and PMSM motor control for industrial drives, and solar micro-inverter or EV onboard charger control stages, where 100 MIPS headroom and fast PWM matter. Design consideration: the 3.0V to 3.6V supply window means the 5V-tolerant design practice of older dsPIC33 families does not apply; level-shift CAN FD and 5V sensor interfaces accordingly, and decouple all VDD/AVDD pairs with 100 nF capacitors placed close to the UQFN pads.

A digital signal controller combines the compute throughput of a microcontroller with DSP engine features such as single-cycle MAC, barrel shifter, and hardware divide. Within the power-management hierarchy, the DSC sits between a general-purpose MCU and a dedicated DSP, providing deterministic control loops for switched-mode power conversion and motor drive. The dsPIC33CK family, built on the dual-issue dsPIC33CK core, is Microchip's current-generation platform for digital power and advanced control, superseding the dsPIC33EP SMPS families. Key differentiating features of the MP505 peripheral set include three integrated analog op-amps (usable in PGA mode), three analog comparators, a 12-bit high-speed ADC capable of up to 3.5 Msps, a 16-channel High-Resolution PWM with 250 ps effective resolution for fine duty-cycle and phase control, CAN Flexible Data (CAN-FD) with up to 8 Mbit/s data phase, and a Peripheral Trigger Generator (PTG) for hardware-sequenced autonomous operation.
