DSPIC33CK128MC105-E/M7 - 16-bit 100MHz DSC 128KB Flash | Microchip

The Microchip Technology DSPIC33CK128MC105-E/M7 is a 16-bit digital signal controller (DSC) with a 100 MHz dsPIC33CK core, 128KB (128K x 8) Flash program memory and 16KB RAM, housed in a 48-pin VQFN (6x6 mm, M7) package. A digital signal controller combines the computational throughput of a DSP with the peripheral integration and deterministic control of a microcontroller. Within the power-management hierarchy of embedded systems, the DSC sits between general-purpose MCUs and full DSPs, making it the preferred class for closed-loop control loops such as field-oriented motor control, digital power conversion and high-speed sensing where multiply-accumulate operations execute in a single cycle. Key features of this device include the single 100 MHz dsPIC DSC core with integrated DSP engine, on-chip operational amplifiers, a 12-bit ADC and a high-speed PWM module purpose-built for power conversion. The -E suffix denotes the extended operating temperature range, and the device belongs to Microchip's functional safety (FuSa) supported dsPIC33CK family, easing documentation for safety-oriented designs. From an architecture standpoint, the dsPIC33CK core executes from Flash with an 8-bit program memory width organization and provides 39 general-purpose I/O. The 3.0V to 3.6V supply window aligns with standard 3.3V rails, allowing direct connection to typical industrial logic levels without level shifting. The integrated op-amps can buffer current-sense signals ahead of the ADC, reducing external component count in motor-drive and power-supply designs. Typical applications include brushless DC and PMSM motor control, digital power supplies (LLC, totem-pole PFC), and industrial embedded control nodes. The high-resolution PWM and fast 12-bit ADC make the part especially suitable for peak-current-mode converters and sensorless FOC drives. When designing with this device, budget decoupling on all VDD/VDDCORE pins and verify that the 100 MHz operation is achieved with the intended oscillator configuration, since clock setup directly affects PWM resolution and ADC sampling rates.

A Digital Signal Controller combines the compute architecture of a microcontroller with DSP-class math capability in a single chip. In the power-management hierarchy, the dsPIC33CK sits between general-purpose MCUs and dedicated DSP ICs: it executes real-time control loops (such as field-oriented motor control or digital power conversion) at speeds that a standard MCU cannot sustain, while retaining the peripherals, interrupt structure, and low cost of an embedded controller. The dsPIC33CK series is Microchip's single-core generation of this category, succeeding the dsPIC33EP family. Key differentiating features of the DSPIC33CK128MC105 include its 100 MIPS-class dsPIC33CK core with DSP instruction extensions, on-chip op-amps that reduce external component count in current-sense circuits, a 12-bit ADC supporting high-speed sampling of control-loop variables, and a high-speed PWM module purpose-built for power conversion topologies. The '-E' suffix denotes an extended temperature grade, and the FuSa qualification support targets safety-oriented designs per IEC functional-safety development flows. Architecturally, the device pairs a 16-bit pipelined CPU with single-cycle MAC and DSP instructions, deterministic interrupt latency for tight control-loop timing, and Flash self-programming for field updates. Memory of 128 KB Flash and 16 KB RAM accommodates complex control algorithms, fieldbus stacks, and diagnostics code simultaneously. Typical applications include brushless DC and PMSM motor drives for industrial automation, digital power supplies (LLC, totem-pole PFC, LLC resonant converters), EV charging and battery-management control boards, and high-performance general embedded control where deterministic real-time behavior is required. Design consideration: operate the device within the specified 3 V to 3.6 V rail and decouple all VDD/VSS pairs with 100 nF ceramics placed directly at the package pins; the 48-TQFP 0.5 mm pitch also demands careful stencil design to avoid solder bridging.

The Microchip Technology DSPIC33CK128MC502T-I/2N is a 16-bit digital signal controller (DSC) delivering up to 100 MIPS of deterministic performance from its dsPIC33CK core, with 128 KB (128K x 8) of FLASH program memory and 16 KB of RAM, housed in a 28-pin UQFN (6x6 mm, 2N) surface-mount package. A digital signal controller combines the computational capability of a DSP with the peripheral integration and control architecture of a microcontroller. Within the embedded hierarchy, the DSC sits between general-purpose MCUs and dedicated DSPs, making it the preferred choice in power conversion and motor control where fast, deterministic interrupt response and precision analog sampling must coexist. Microchip's dsPIC33CK family implements this concept with a single-core, high-performance pipeline and tightly coupled PWM and ADC peripherals. Key features of the DSPIC33CK128MC502 include a 100 MHz (100 MIPS) dsPIC DSC core, on-chip operational amplifiers, a 12-bit ADC supporting high-rate conversions of motor phase currents, high-resolution PWM peripherals suitable for Field-Oriented Control (FOC), and CAN FD for robust industrial and automotive networking. The device operates from a 3.0 V to 3.6 V supply and offers 21 general-purpose I/O lines. Architecturally, the dsPIC33CK core executes most instructions in a single cycle with a zero-cycle (zero-overhead) DSP multiply-accumulate path, providing predictable worst-case timing that is critical for current-loop control at switching frequencies of 100 kHz and above. The ADC can be coupled with the PWM trigger hardware to sample exactly at the center of the PWM carrier, minimizing switching-noise-induced conversion errors without CPU intervention. Typical applications include brushless DC and PMSM motor drives using sensorless FOC, digital power supplies such as LLC and totem-pole PFC converters, CAN FD-connected industrial nodes, and high-intensity LED drivers. The integrated op-amps reduce external component count in current-sensing signal chains. Design consideration: the 3.0 V to 3.6 V supply range means a 5 V system bus requires an LDO or buck regulator ahead of the VDD pin, and decoupling plus the internal regulator capacitor must follow the datasheet layout guidance for noise immunity.

Architecturally, the dsPIC33CK core pairs a 16-bit CPU with DSP-enhanced instruction extensions and a two-stage instruction pipeline, while the enhanced peripheral ecosystem (DMA, configurable logic, and analog comparators) offloads time-critical tasks from software. The integrated op-amps directly buffer shunt-resistor current signals into the ADC, reducing external component count in motor-control designs. Typical applications include brushless DC (BLDC) and PMSM motor control, digital power conversion (totem-pole PFC, LLC converters), industrial automation nodes, and automotive-adjacent systems requiring CAN FD communication. Design consideration: the dsPIC33CK family typically requires a VCAP/VDDCORE stabilizing capacitor; follow the power-up sequencing and decoupling guidance in the manufacturer datasheet, and budget Flash carefully - 128KB is ample for FOC motor-control firmware with communication stacks.
