DSPIC33CK32MP502-I/SS 개요
A digital signal controller combines the computational throughput of a digital signal processor with the peripheral integration and control-oriented architecture of a microcontroller. Within the power-management hierarchy, a DSC sits between a general-purpose MCU and a dedicated DSP, executing real-time control loops for switching power converters and motor drives while handling communication and housekeeping tasks on the same die.
Key features include the modified Harvard architecture DSP engine with single-cycle MAC and 40-bit accumulators, dual-partition program flash enabling Live Update firmware upgrades without downtime, and memory built-in self-test (MBIST) supporting functional-safety (FuSa) development. The peripheral ecosystem spans four DMA channels, CAN FD for industrial networks, 12-bit ADCs, high-resolution PWM for switching converters, and integrated op-amps that reduce external component count.
The dsPIC33CK core achieves DC to 100 MIPS operation from a 3.0V to 3.6V supply using CMOS process technology, with a 24-bit program memory width supporting fixed-point arithmetic. Interrupt latency and deterministic execution make it suitable for control loops in the 10 kHz to 100 kHz range, common in digital power and brushless motor control designs.
Typical applications include switch-mode power supplies (SMPS), power factor correction (PFC), brushless DC (BLDC) and PMSM motor drives, digital battery charging, and CAN FD-connected industrial sensing and control nodes.
For design, select the dual-partition flash for OTA-capable products and reserve the 4 DMA channels for ADC-to-RAM streaming to keep the control loop deterministic.

일반적인 애플리케이션
DSPIC33CK32MP502-I/SS 적합 용도: 6 애플리케이션s: Digital Switch-Mode Power Supplies (SMPS), BLDC / PMSM Motor Control, Power Factor Correction (PFC), CAN FD Industrial Control Nodes, Digital Battery Chargers, Advanced Sensing and Control.
Digital Switch-Mode Power Supplies (SMPS)
The DSPIC33CK32MP502-I/SS fits digital SMPS designs because its high-resolution PWM provides fine duty-cycle granularity for tight output regulation, while the 100 MIPS core executes voltage- and current-mode control loops well beyond the 100 kHz switching range. The 12-bit ADCs sample feedback signals, and the 4 DMA channels stream samples to RAM without CPU intervention, keeping loop latency deterministic. Integrated op-amps can condition current-shunt signals directly. With dual-partition flash and Live Update, firmware control-law upgrades are possible without power-cycling the supply, and ECC plus MBIST support functional-safety requirements in telecom and server power stages.
추천
BLDC / PMSM Motor Control
For brushless DC and permanent-magnet synchronous motor drives, the DSPIC33CK32MP502-I/SS offers field-oriented control (FOC) capability at 100 MIPS with single-cycle MAC DSP instructions. The high-resolution PWM drives three-phase inverter bridges with fine pulse resolution, the 12-bit ADCs capture phase currents, and the on-chip op-amps amplify low-level shunt signals, reducing external component count and board area. The 28-pin SSOP package suits compact drive boards. CAN FD connectivity enables networked motor nodes in industrial automation, while -40C to +150C operation tolerates drive enclosures near hot power stages.
추천
Power Factor Correction (PFC)
In active PFC front-ends, the DSPIC33CK32MP502-I/SS executes average-current-mode control with its 100 MIPS core while the high-resolution PWM minimizes ripple-induced distortion at the switching node. The 12-bit ADCs simultaneously sample input voltage, inductor current, and bus voltage, and the DMA controller maintains deterministic sampling even at high switching frequencies. Dual-partition flash allows control-firmware revisions in the field across the product lifetime. The -40C to +150C range and FuSa-oriented ECC/MBIST features suit AC-line-powered industrial and appliance designs where reliability and compliance documentation are required.
추천
CAN FD Industrial Control Nodes
The integrated CAN FD controller makes the DSPIC33CK32MP502-I/SS a strong fit for industrial sensing and control nodes on robust networks. CAN FD payloads up to 64 bytes carry richer telemetry than classic CAN, and the 100 MHz core can package, filter, and process messages without external logic. Combined with 12-bit ADCs and integrated op-amps, the node can digitize local sensors and stream results onto the bus deterministically. The 28-pin SSOP keeps node hardware compact, and dual-partition flash with Live Update enables remote firmware upgrades across deployed fleets without downtime.
추천
Digital Battery Chargers
Battery-charging applications benefit from the DSPIC33CK32MP502-I/SS combination of high-resolution PWM for precise charge-current regulation, 12-bit ADCs for voltage/current/temperature monitoring, and DSP throughput for charging state machines and coulomb-counting algorithms. The on-chip op-amps condition current-sense signals, reducing external analog parts. The -40C to +150C temperature grade tolerates charger enclosures, and ECC-protected flash plus MBIST support functional-safety arguments for lithium-charging protection. CAN FD (or UART) provides communication with battery management systems and chargers networked in industrial or motive-power environments.
추천
Advanced Sensing and Control
For advanced sensing nodes, the DSPIC33CK32MP502-I/SS provides 12-bit ADCs, on-chip op-amps for sensor signal conditioning, and 100 MIPS of DSP capability to run filtering and classification algorithms on-die. The modified Harvard architecture's dual data paths let the CPU sustain control updates while DSP routines process sensor streams, and the 4 DMA channels move data without software overhead. MBIST and ECC appeal to safety-conscious sensing systems, while Live Update dual-partition flash supports field recalibration. The 28-SSOP package integrates into compact probe, actuator, and industrial instrument form factors.

설계 노트
Supply the DSPIC33CK32MP502-I/SS from a clean 3.0V to 3.6V rail. Decouple each VDD pin with at least 0.1 uF ceramic placed within 2 mm of the pin, plus one bulk 4.7 uF to 10 uF capacitor per board. Pin 28 (VCAP/VDDCORE) requires the manufacturer-specified core-regulator capacitor - omitting or under-sizing it causes brownouts during 100 MHz code execution. Estimated: at 100 MHz with typical peripheral loading, active core current is in the tens of mA range; verify exact figures against the datasheet electrical characteristics table for your thermal budget.
The 28-SSOP (0.65 mm pitch) land pattern requires careful solder-paste stencil design to avoid bridging between the 0.65 mm pitch leads. Keep the CAN FD differential pair (C1TX/C1RX) routed as 120 ohm matched traces to the transceiver, and route PWM outputs away from the 12-bit ADC analog inputs to prevent switching noise coupling into current-sense channels. Use a solid ground plane under the analog section and star-connect analog returns.
Do not exceed 3.6V on any I/O pin - the dsPIC33CK is a 3.3V-only device and is not 5V tolerant. When migrating from dsPIC33EP parts, note that configuration bits and oscillator setup differ on the CK family. When using dual-partition Live Update, plan the bootloader around the active-partition swap early in the project; retrofitting OTA into single-partition code is non-trivial. Always verify the I-grade temperature claim against the actual junction temperature at 100 MHz, not just ambient.
For motor-control and digital-power designs, keep the loop from current shunt to op-amp input to ADC as short as possible and use Kelvin connections at the shunt resistor. The on-chip op-amps have bandwidth limits documented in the datasheet - for very high-bandwidth current sensing, verify settling time against your PWM switching frequency. Synchronize ADC sampling to the PWM trigger to sample away from switching transitions and reduce noise in FOC control loops.
