DSPIC33CK256MP202T-I/SS

DSPIC33CK256MP202T-I/SS - 100MHz 16-bit DSC, 256KB | Microchip

The Microchip Technology DSPIC33CK256MP202T-I/SS is a 16-bit digital signal controller (DSC) running at up to 100 MHz, with 256 KB of dual-panel ECC Flash and 24 KB of RAM, housed in a 28-pin SSOP (0.209 in / 5.30 mm width) package. A digital signal controller combines the computational core of a microcontroller with DSP-class arithmetic capability in a single chip. In the power-management hierarchy, a DSC sits above general-purpose MCUs for real-time control loops: its deterministic interrupt latency and multiply-accumulate (MAC) throughput let firmware close current and voltage loops at hundreds of kilohertz, which a standard 8-bit or low-end 16-bit MCU cannot reliably do. The dsPIC33CK family is Microchip's flagship DSC line for digital power and motor control. Key features of the DSPIC33CK256MP202T-I/SS include the 100 MHz dsPIC33C core with DSP and fixed-point instructions, 256 KB of ECC-protected dual-panel Flash allowing live firmware updates, 24 KB of RAM, integrated operational amplifiers, 12-bit ADCs rated up to 3.5 Msps, high-resolution PWM with edge resolutions down to the 2 ns class, and CAN Flexible Data (CAN FD) support. Dual-panel Flash plus ECC makes the part suited to functional-safety oriented designs, consistent with its DigiKey listing as a Functional Safety (FuSa) microcontroller. Architecturally, the device uses a modified Harvard bus with a 24-bit instruction word, DMA channels that offload the CPU for ADC-to-RAM transfers, and hardware cycle-limiting to guarantee loop timing. The on-chip op amps can be routed internally to the ADC, shrinking the analog front end of current-shunt sensing circuits. Typical applications include digital switch-mode power supplies (LLC, totem-pole PFC), PMSM and BLDC motor control, solar micro-inverters, battery chargers, and industrial sensing nodes. Design consideration: at 100 MHz, supply decoupling and ADC reference layout directly influence conversion accuracy - follow Microchip's analog layout guidance with solid VDD/VSS and AVDD/AVSS pairs and short shunt connections to the integrated op-amp inputs.

The device integrates 3 on-chip operational amplifiers and 3 comparators, offloading external analog signal-conditioning stages in power converters. The modified Harvard architecture with a high-resolution PWM (HRPWM) module and CAN Flexible Data (CAN FD) interface makes this DSC well suited to digital power supplies, motor control, and advanced sensing and control systems. Functional Safety (FuSa) documentation support further enables safety-relevant industrial designs. Typical applications include digitally controlled AC-DC and DC-DC power supplies, brushless DC and PMSM motor drives, and power-factor-correction stages where the 100 MIPS core and integrated op-amps execute fast current loops. Design consideration: the -40C to +150C extended temperature range of the E-grade requires attention to total power dissipation and PCB copper area to stay within junction limits at high ambient temperatures.

The MP peripherals are particularly rich: 3 on-chip operational amplifiers, 3 comparators, and a Peripheral Trigger Generator (PTG), reducing external component count in power supplies and motor control boards. Technically, the dsPIC33C core delivers DSP multiply-accumulate performance with hardware divide, multiple interrupt priorities, and a 4-channel DMA controller for low-overhead data movement between ADC results and memory. The device operates from -40C to +85C (industrial, -I temperature grade) and supports the Functional Safety (FuSa) package classification, which aids compliance-driven designs. Typical applications include digital power supplies (totem-pole PFC, LLC converters exploiting the 250 ps PWM resolution), BLDC and PMSM motor control using the integrated op amps for current sensing, and industrial CAN FD nodes for automation and telecom rectifiers. A key design consideration: the 3.0-3.6 V operating range requires a clean 3.3 V rail, and the exposed pad must be soldered to a ground pour for thermal and signal-integrity reasons.
