DSPIC33CK128MP203-I/M5 - 100MHz 16-bit DSC, 128KB Flash | Microchip

The Microchip Technology DSPIC33CK128MP203-I/M5 is a 100 MHz single-core 16-bit digital signal controller (DSC) with 128 KB of program Flash (with ECC and dual-partition live update), 16 KB of data SRAM with memory built-in self-test (MBIST), and an integrated 36-pin UQFN 5x5 mm exposed-pad package. A digital signal controller is a hybrid device that combines the computational throughput of a digital signal processor (DSP) with the peripheral integration and control-oriented architecture of a microcontroller (MCU). Within the power-management hierarchy, the DSC sits above general-purpose MCUs for real-time control loops, making dsPIC33C-class devices the preferred choice for digitally controlled power conversion and motor drive systems. Key features of this part include the dsPIC33CK DSC core executing up to 100 MIPS over the full 3.0V to 3.6V operating range, three integrated operational amplifiers and three analog comparators that offload analog signal conditioning from external components, a peripheral trigger generator (PTG), high-resolution PWM, 12-bit ADCs, and CAN Flexible Data (CAN FD) support across the dsPIC33CK family. The dual-partition Flash with live update enables field firmware upgrades without a bootloader downtime window. Architecturally, the device uses a modified Harvard architecture with a 24-bit instruction word, DSP multiply-accumulate and barrel shifter hardware, and DMA channels for moving ADC results and communication data without CPU intervention. ECC on program Flash protects against single-bit memory faults, supporting functional-safety (FuSa) development flows. Typical applications include digital power supplies (LLC, totem-pole PFC), brushless DC and PMSM motor control, solar micro-inverters, and automotive sensing subsystems where the integrated op-amps directly amplify shunt or phase currents. When designing with this controller, budget the 3.3V rail carefully and exploit the integrated op-amps to reduce BOM cost, but verify their bandwidth against your control-loop frequency.

Key features of this device include the 100 MHz dsPIC core with DSP engine, three integrated operational amplifiers, three analog comparators, high-resolution PWM peripherals suited for power conversion, and PTG (Programmable Toggle Generator) hardware. The -I temperature suffix denotes industrial operation from -40C to +85C, and the T suffix indicates tape-and-reel packaging. The device operates from a 3.0V to 3.6V supply and supports In-Circuit Serial Programming (ICSP) via PGC/PGD pins. Technically, the dsPIC33CK128MP203 integrates multiple internal bus architectures and DMA channels that offload data movement from the CPU, which is essential for high-frequency control loops where interrupt latency directly affects loop bandwidth.

Typical applications include digital power supplies (LLC, totem-pole PFC, buck/boost converters), BLDC and PMSM motor control with sensorless field-oriented control, and digital lighting or battery-charging systems. The three on-chip op-amps can be used as current-sense amplifiers, reducing external component count in motor-drive and power-converter designs. For design, note that the UQFN exposed-pad package requires a solid ground pour beneath the device for thermal dissipation and signal integrity; decouple the 3.3V rail with 0.1uF ceramics at each VDD pin. Programmers must supply a stable 3.3V VDD during ICSP.

DSPIC33CK128MP502-E/SS - 100MHz 16-bit DSC CAN-FD | Microchip

The Microchip Technology DSPIC33CK128MP502-E/SS is a 16-bit digital signal controller (DSC) featuring a 100 MHz dsPIC33CK core, 128 KB of dual-partition program flash with ECC, and 16 KB of RAM, housed in a 28-pin SSOP package rated for -40C to +150C operation. It integrates CAN Flexible Data (CAN FD), analog op-amps, 12-bit ADCs, and high-resolution PWM peripherals on a single chip. A digital signal controller combines the computational power of a DSP with the peripheral set and ease of use of a microcontroller. In the power-management hierarchy, DSCs sit between general-purpose MCUs and dedicated DSPs: they execute control-loop mathematics (PID, compensation filters, field-oriented control) in hardware-friendly instructions while providing motor-control PWMs and fast analog-to-digital conversion, making them the de facto processor class for digital power supplies and motor drives. Key differentiating specifications include the 100 MIPS dsPIC33CK DSC core (DC to 100 MIPS per the family datasheet), dual-panel flash supporting live firmware updates, and a rich analog front end: on-chip operational amplifiers and 12-bit ADCs eliminate external amplifiers in current-sense loops. The extended temperature range (-40C to +150C, denoted by the -E suffix) and Functional Safety (FuSa) support qualify the device for harsh automotive and industrial environments. Technically, the device uses a modified Harvard architecture with a 24-bit instruction word and a DSP engine with single-cycle MAC and dual operand fetch, sustaining deterministic execution of time-critical control loops. The 128 KB flash is dual-partitioned with error correction code (ECC), enabling fail-safe over-the-air or field firmware updates without external memory. Dedicated PWM peripherals with high resolution address switching frequencies well into the hundreds of kilohertz for digital power conversion. Typical applications include digital switched-mode power supplies (AC-DC, DC-DC), PFC stages, brushless DC and PMSM motor control for industrial drives and e-mobility accessories, CAN FD networked sensor nodes, and LED drivers. The CAN FD module directly interfaces to automotive and industrial buses while the 150C rating covers under-hood and high-power enclosure locations. For design, note the narrow operating supply window of 3.0V to 3.6V; a 3.3V LDO or buck regulator with low noise is recommended, and all unused I/O should be configured to a defined state per Microchip's functional safety guidance. Keep the analog reference routing separate from PWM power loops for best ADC accuracy.

Typical applications include digital power supplies (totem-pole PFC, LLC converters), brushless DC and PMSM motor control, USB-PD and wireless-charging power stages, and advanced sensing systems. The 3.3 V supply and rich analog front end make it well suited to compact power-conversion boards. When designing with this device, budget the 3.0-3.6 V supply rail early and exploit the multiple PGECx/PGEDx pin pairs for in-circuit serial programming (ICSP); use PGEC2/PGED2 as a matched pair only.

The dsPIC33CK core executes most instructions in a single cycle at 100 MIPS, with a fixed-point DSP engine supporting (x)y addressing and modulo/bit-reversed modes. Multiple DMA channels offload ADC-to-RAM transfers, keeping the CPU free for the control loop. Context switching latency is minimized for nested interrupts, which matters for multi-ratio phase-shifted converters and FOC motor algorithms executed at tens of kilohertz. Typical applications include digital power supplies (LLC, phase-shifted full bridge, totem-pole PFC), BLDC/PMSM field-oriented motor control, automotive subsystems such as pumps, fans and lighting ballasts, and high-current battery chargers where CAN-FD and precision PWM converge. The three on-chip op-amps can close current-shunt loops without external amplifiers, reducing BOM cost and board area. Design consideration: the UQFN exposed pad must be soldered to a grounded thermal land to meet thermal and EMI targets; also budget the 3.3V single-supply domain when interfacing to 5V sensors.
