DSPIC30F2011-20E/P 概要
A Digital Signal Controller combines the computational power of a DSP engine with the peripheral set and ease of use of a microcontroller. In the product hierarchy, the dsPIC30F2011 sits within the 16-bit DSC category, bridging general-purpose MCUs such as the PIC24 family and full DSPs, making it a power management and sensing workhorse for mixed signal-control designs. According to Microchip, the dsPIC30F Sensor Family offers seamless migration options to dsPIC33F, PIC24H, or PIC24F devices in similar packages.
Key features include the 16-bit modified Harvard architecture with a dedicated DSP engine executing DSP instructions alongside MCU instructions, 20 MIPS throughput at the 20E extended-temperature speed grade, and 12 KB of self-programmable Flash with in-circuit serial programming (ICSP) support. The device integrates motor-control and sensor-oriented peripherals including multiple PWM outputs, a 10-bit ADC, UART, SPI, and I2C interfaces, plus 21 general-purpose I/O lines per the family datasheet.
Architecturally, the dsPIC30F core pairs a 16-bit MCU pipeline with a 16-bit x 16-bit multiplier, 40-bit accumulator, and dual addressing supporting DSP MAC operations. The wide 2.5 V to 5.5 V operating range allows direct connection to 5 V industrial rails, simplifying interface to legacy sensors and actuators without level shifting.
Typical applications include switch-mode power supply (SMPS) control, sensor signal conditioning and acquisition nodes, brushless DC and induction motor control, lighting ballasts, and industrial instrumentation where DSP-grade math is needed at low cost.
When designing with this device, plan for the extended-temperature 20E grading if your application exceeds -40 C to +85 C, and budget Flash carefully since 12 KB (4K x 24 instructions) is fixed and non-expandable in this package.

主な用途
DSPIC30F2011-20E/P の用途: 6 件s: Switch-Mode Power Supply (SMPS) Digital Control, Sensor Signal Conditioning and Acquisition, Industrial Motor Control, Lighting Ballasts and LED Drivers, Embedded Power Conversion and UPS, Test, Measurement, and Instrumentation.
Switch-Mode Power Supply (SMPS) Digital Control
The DSPIC30F2011-20E/P was architected specifically as a switch-mode power supply digital signal controller - archived datasheet specifications describe the 28/44-pin family members as 'High-Performance Switch Mode Power Supply Digital Signal Controllers'. Its 20 MIPS core provides the computation speed required for voltage-mode or current-mode digital loop closure at switching frequencies in the tens to hundreds of kHz, while the on-chip 10-bit ADC samples feedback rails without an external converter. Dedicated PWM outputs drive buck, boost, or flyaway power stages directly through a gate driver. The 2.5 V to 5.5 V supply range and extended -40 C to +125 C grade tolerate industrial power-supply environments. In a typical topology, the ADC samples the output divider each switching cycle, the DSP core executes the compensator, and the PWM module updates its duty cycle - a deterministic digital control loop with no external analog compensator components.

Sensor Signal Conditioning and Acquisition
As a member of Microchip's dsPIC30F Sensor Family, the DSPIC30F2011-20E/P is designed to sit close to analog sensors and perform real-time filtering, calibration, and linearization. The integrated 10-bit ADC digitizes sensor outputs from pressure, temperature, or position transducers, while the DSP engine's 16-bit x 16-bit MAC with 40-bit accumulator executes FIR/IIR filtering efficiently at 20 MIPS. UART, SPI, and I2C interfaces stream processed results to a host controller or HMI. The wide 2.5 V to 5.5 V supply supports direct connection to 5 V bridge sensors and 3.3 V logic alike, and the extended -40 C to +125 C temperature range permits mounting inside enclosures near motors or heat sources. Because it blends MCU peripherals with DSP math in one 18-pin through-hole package, designers replace discrete amplifier-filter-ADC chains with a single controller, reducing BOM count in industrial sensor nodes and portable instruments.
おすすめ
Industrial Motor Control
The dsPIC30F core's DSP engine makes the DSPIC30F2011-20E/P well suited to controlling small brushless DC, permanent-magnet, or single-phase induction motors in industrial equipment. Its PWM module generates the complementary or independent drive waveforms needed for inverter legs, and the 10-bit ADC samples current-shunt and back-EMF feedback for commutation and closed-loop speed control. At 20 MIPS, the controller executes field-oriented or trapezoidal commutation algorithms within tight loop deadlines. The extended -40 C to +125 C operating range and 5.5 V maximum supply match industrial cabinet environments, and the 18-pin PDIP through-hole package simplifies prototyping and rework on breadboard-style control boards. The 12 KB Flash is sufficient for trapezoidal sensor-based BLDC control and basic PI speed loops; larger firmware (sensorless FOC) may warrant the pin-compatible DSPIC30F3012-20E/P with 24 KB Flash.
おすすめ
Lighting Ballasts and LED Drivers
Digital control of fluorescent ballasts and high-power LED drivers benefits directly from the DSPIC30F2011-20E/P's parameter set. The PWM outputs generate the fixed-frequency drive signals for half-bridge or resonant stages, while the 10-bit ADC monitors lamp current, bus voltage, and temperature for closed-loop regulation and protection. At 20 MIPS, the controller can implement ignition sequencing, dimming profiles, and fault shutdowns deterministically. The wide 2.5 V to 5.5 V supply range allows the controller to share a rail with gate-driver logic, and the extended -40 C to +125 C grade survives luminaire thermal environments. The 18-pin PDIP through-hole package eases low-volume and serviceable luminaire designs where SMD rework is impractical. Designers should budget Flash carefully - ignition state machines plus soft-start ramps fit within the 12 KB (4K x 24) program space with headroom for communication if kept lean.
おすすめ
Embedded Power Conversion and UPS
Uninterruptible power supplies, inverters, and battery chargers require deterministic real-time control that the DSPIC30F2011-20E/P delivers in a low-cost 18-pin through-hole package. Its 20 MIPS DSP core runs the phase/frequency tracking and inverter modulation math, the 10-bit ADC samples AC output and DC bus feedback, and dedicated PWM outputs drive the power stage through isolation. The extended -40 C to +125 C temperature rating and 2.5 V to 5.5 V supply tolerance accommodate the electrical noise and thermal stress typical of power-conversion enclosures. ICSP in-circuit programming allows field firmware updates without desoldering - a practical benefit for through-hole PDIP designs serviced in the field. The 12 KB Flash accommodates core control loops and housekeeping; applications adding communication stacks (Modbus over UART, for instance) should evaluate the pin-compatible DSPIC30F3012-20E/P with 24 KB Flash to avoid space pressure.
おすすめ
Test, Measurement, and Instrumentation
Bench instruments, data loggers, and industrial meters exploit the DSPIC30F2011-20E/P's combination of DSP throughput and MCU-style peripherals. The 10-bit ADC digitizes measurement channels, the DSP engine performs averaging, RMS computation, and digital filtering at 20 MIPS, and the UART streams formatted results to a PC or display controller over RS-232/RS-485. The 18-pin PDIP through-hole package is a major advantage for prototype instrumentation and educational/lab equipment, where sockets allow firmware iteration without soldering. Operating from 2.5 V to 5.5 V, the device interfaces with both 3.3 V and 5 V analog front ends without level translation, and the -40 C to +125 C range supports outdoor and industrial panel instruments. The seamless Microchip migration path to PIC24H/dsPIC33F devices in similar packages provides an upgrade route if higher resolution or speed is needed later in the product life cycle.

設計ノート
The DSPIC30F2011-20E/P accepts 2.5 V to 5.5 V, but full 20 MIPS performance should be verified against VDD in the Microchip data sheet (document 70139), as dsPIC30F speed grades can derate at reduced supply voltage. Decouple VDD with a 0.1 uF ceramic capacitor placed within a few millimeters of the pin, plus a 4.7 uF to 10 uF bulk capacitor per board. Keep MCLR pulled up through a 10 kOhm resistor with an ICSP-compatible programming header (VPP, PGD, PGC) for in-circuit Flash programming.
As a through-hole 18-PDIP part, layout is forgiving, but analog performance still depends on grounding. Use a solid ground plane under the ADC input traces, keep high-current PWM/SMPS switching nodes physically separated from the ADC and VREF pins, and add a small RC filter (e.g., 100 Ohm + 1 nF, sized per your source impedance) on analog inputs before sampling. Assign analog functions to the pins Microchip designates as ANx on the 18-pin map to preserve best ADC routing.
The 12 KB (4K x 24 instruction) Flash is non-expandable in this fixed part; complex sensorless motor algorithms, RTOS kernels, or full communication stacks can overflow quickly - estimate code size early and consider the pin-compatible DSPIC30F3012-20E/P (24 KB) if headroom is marginal. Also, confirm the -E extended grade (-40 C to +125 C) is genuinely required before design lock: the -20I/P industrial grade (to +85 C) is typically cheaper and easier to source, though verify current lifecycle status per variant.
Estimated: an 18-pin PDIP DSC running at 20 MIPS with typical 5 V supply dissipates on the order of tens of milliwatts to roughly 100 mW of core/I-O power, far below the PDIP thermal capability; no heatsink is required. Thermal concern arises only when heavy I/O source/sink current is driven continuously - keep total pin current within the data sheet absolute maximum ratings and budget per-port limits as specified in document 70139.
