DSPIC33CK128MP202-E/SS 개요
A digital signal controller combines the compute throughput of a digital signal processor with the peripheral integration and ease of use of a microcontroller. In the power-management hierarchy, DSCs sit between general-purpose MCUs and full DSPs, providing multiply-accumulate DSP instructions alongside timers, PWM modules and high-speed ADCs - a combination purpose-built for closed-loop control systems such as switch-mode power supplies, motor drives and power-factor-correction stages.
Key features include up to 100 MIPS performance, dual-panel Flash with ECC and Live Update support for in-field firmware upgrades, memory built-in self-test (MBIST) for functional-safety designs, integrated operational amplifiers, 12-bit ADCs and high-resolution PWM peripherals. The -E extended temperature suffix plus AEC-Q100 qualification makes this member suitable for automotive and harsh-environment industrial applications.
Architecturally, the dsPIC33CK core uses a modified Harvard architecture with a single 100 MHz pipeline stage, DSP multiply-accumulate hardware and hardware division. The dual-partition program memory enables booting from either partition, supporting safe live-update sequences required in automotive OTA and functional-safety contexts.
Typical applications include digital power supplies and LLC/PFC converters, brushless DC and PMSM motor control, automotive LED drivers and onboard chargers, and high-precision sensing systems. The integrated op-amps and 12-bit ADC reduce external analog component count in current-sensing loops.
Design consideration: the device requires a VCAP pin stabilizing capacitor and careful AVDD/AVSS decoupling for ADC accuracy; the -E grade only guarantees -40C to +125C, so verify junction temperature margins at 100 MIPS operation.

일반적인 애플리케이션
DSPIC33CK128MP202-E/SS 적합 용도: 6 애플리케이션s: Digital Power Supplies (LLC, PFC), Brushless DC and PMSM Motor Control, Automotive LED Lighting and Onboard Chargers, Power-Factor Correction and Solar Microinverters, Industrial Sensing and Closed-Loop Control, Battery Management and DC-DC Modules.
Digital Power Supplies (LLC, PFC)
The DSPIC33CK128MP202-E/SS fits digital power applications because its 100 MHz core executes control loops at loop rates of hundreds of kHz while the integrated high-resolution PWM and 12-bit ADC keep phase and sampling jitter minimal. In an LLC or PFC stage it reads inductor current and output voltage through on-chip op-amp front-ends, computes compensation in DSP fixed-point arithmetic, and updates PWM duty with sub-nanosecond resolution. The 128 KB dual-panel Flash with ECC and Live Update supports firmware field upgrades on deployed power supplies without hardware changes.
추천
Brushless DC and PMSM Motor Control
For sensorless FOC motor drives, the 100 MIPS dsPIC33CK core closes current-loop bandwidths above 10 kHz, with DSP multiply-accumulate hardware executing Clarke/Park transforms within a single PWM period. The 12-bit ADC triggers synchronously with PWM, sampling all three phase currents via the integrated op-amps, which removes external amplifier stages and board area. The AEC-Q100 qualification and -E extended grade let this DSC run inside automotive pump, fan and traction-auxiliary drives where ambient temperatures exceed +85C.
추천
Automotive LED Lighting and Onboard Chargers
Automotive headlamp boost converters and LED current regulators benefit from the DSC's high-resolution PWM for dimming without visible flicker, and the 3.0V-3.6V robust IO directly drives gate drivers. In onboard charger PFC stages, the ECC-protected Flash and functional-safety features (MBIST) support safety-critical firmware. The -E extended temperature grade (-40C to +125C) is mandatory in under-hood and lamp-enclosure environments, and AEC-Q100 qualification satisfies automotive production-part approval requirements.
추천
Power-Factor Correction and Solar Microinverters
In grid-tied microinverter and PFC front ends, the 100 MHz core sustains 100 kHz switching control loops while computing MPPT and grid synchronization algorithms concurrently in interrupt-time slices. The 12-bit ADC samples grid current and voltage with the integrated op-amps conditioning shunt signals, and the DSP fixed-point MAC accelerates sine/cosine computation for phase-locked loops. Dual-partition Flash with Live Update allows field firmware revision of deployed inverters, a key requirement for long-life renewable installations.
추천
Industrial Sensing and Closed-Loop Control
The DSC handles advanced sensing tasks - pressure, load and current sensing - by combining on-chip op-amp gain stages with the 12-bit ADC for direct bridge or shunt interfaces, then applying DSP filtering (IIR/FIR) at full core speed. Remappable RPn pins let designers route UART, SPI and QEI peripherals to any of the free I/O in the 28-SSOP, easing layout of compact sensor nodes. The 16 KB SRAM with MBIST provides data integrity checks required in functional-safety industrial machinery monitoring.
추천
Battery Management and DC-DC Modules
Battery charger, balancer and telecom DC-DC module designs use the DSC's deterministic interrupt latency and hardware DSP to run coulomb counting, protection state machines and synchronous buck control simultaneously. The high-resolution PWM implements phase-shifted full-bridge topologies with precise dead-time control, while the 12-bit ADC monitors cell voltages and temperature via the op-amp front ends. The 28-SSOP package keeps controller footprint small in dense power modules, and AEC-Q100 qualification extends use into automotive 48V subsystems.

설계 노트
The dsPIC33CK128MP202 requires a stabilizing capacitor on the VCAP pin (pin 17) for its internal 1.8V core regulator - follow the value in the Microchip datasheet (low-ESR ceramic) and place it directly at the pin with a short ground return. Decouple both VDD pins (7, 13) and AVDD (26) with 0.1 uF ceramics, and connect AVDD through an RC or ferrite filter from VDD to preserve 12-bit ADC noise performance in digital power designs.
Route PWM outputs away from the analog front end to prevent kickback into the op-amp/ADC inputs during switching edges; use AVSS as the single analog return to a quiet ground point. Remappable RPn pins let you relocate UART/SPI signals during layout iteration - assign critical PWM and ADC pins first in MPLAB Code Configurator, then fix them in firmware before routing. Keep the crystal loop (OSC1/OSC2, pins 9-10) compact with ground guard for clock stability at 100 MIPS operation.
Estimated: at 100 MHz full-speed operation, core current is on the order of tens of mA (verify exact figure in the datasheet DC characteristics section), so power dissipation in the 28-SSOP typically stays below a few hundred mW - the SSOP thermal resistance permits -E grade operation to +125C ambient only when dissipation is low and copper pour aids heat spreading. Confirm junction temperature margin with your actual I/O loading before committing to under-hood designs.
Do not swap the -E and -I suffixes casually: the -E extended grade (this part) is specified to +125C while the -I grade stops at +85C - designs that passed industrial qualification will fail extended-temperature testing with the I part. Also, dual-panel Flash Live Update requires the bootloader to manage partition switching; an unpartitioned design treats memory as a single block (0x000000 onward) and cannot perform live updates without a firmware update strategy.
