DSPIC30F2011-20I/P 概要
A Digital Signal Controller blends the features of a microcontroller (MCU) and a Digital Signal Processor (DSP) into a single-chip solution, allowing engineers to add DSP features such as multiply-accumulate operations to embedded applications without a separate DSP. Within the power management hierarchy, the dsPIC30F family sits under 16-bit digital signal controllers alongside the higher-speed 40 MIPS dsPIC33F family; the 30F family is designed for applications where 5 V operation is important, while dsPIC33F targets lower-voltage, higher-performance designs.
Key features include high-performance 16-bit architecture with DSP instruction support, Flash-based program memory for field reprogramming, operation at up to 20 MIPS (40 MHz input per Newark listing), and migration paths to dsPIC33F, PIC24H, or PIC24F devices in similar packages. The through-hole DIP package makes this part ideal for prototyping, breadboarding, education, and repair of legacy industrial boards.
Architecturally, the dsPIC30F2011 combines a modified Harvard 16-bit MCU core with DSP engine functionality, providing deterministic interrupt handling suitable for sensor signal conditioning and simple closed-loop control. Typical applications include sensor systems, motor control, industrial automation, and embedded control boards that benefit from on-chip DSP capability.
A key design consideration: the dsPIC30F family operates from a 5 V supply, so level shifting is required when interfacing with 3.3 V peripherals; seamless migration to dsPIC33F/PIC24H in similar packages solves this when redesigning.

主な用途
DSPIC30F2011-20I/P の用途: 6 件s: Sensor Signal Conditioning, Industrial Automation and Control, Motor Control, Embedded Prototyping and Education, Legacy Board Repair and Obsolescence Management, Battery-Powered and Portable Instruments.
Sensor Signal Conditioning
The DSPIC30F2011-20I/P belongs to Microchip's dsPIC30F Sensor Family, purpose-built for sensor-centric embedded systems. Its 16-bit DSP engine executes multiply-accumulate filtering (IIR/FIR) on raw analog sensor data, while 20 MIPS throughput provides deterministic interrupt latency for sample-loop timing. As a 5 V device in an 18-pin DIP, it interfaces directly with legacy 5 V sensor outputs without level shifters, reducing BOM cost. Place the ADC sampling in a timer-triggered ISR and apply the DSP library's filter functions; the trade-off versus a pure MCU is slightly higher unit cost, repaid by cleaner, filtered measurement data.
おすすめ
Industrial Automation and Control
In factory automation nodes, the DSPIC30F2011-20I/P offers industrial -40C to +85C temperature rating and 5 V noise-tolerant I/O suited to PLC-adjacent sensor boards and actuator drivers. The 20 MIPS core handles PID control loops with predictable timing, and Flash program memory permits field firmware updates without socket swaps. Through-hole DIP mounting simplifies maintenance replacements in long-life industrial equipment. Designers should clamp inductive loads with flyback diodes and isolate the controller from motor noise; the migration path to PIC24/dsPIC33F in similar packages (per Microchip) future-proofs the design for 3.3 V next-generation platforms.
おすすめ
Motor Control
Simple motor control tasks - DC motor PWM control, closed-loop speed regulation with encoder feedback - map well to the DSPIC30F2011-20I/P. Its DSP engine computes fast PID updates at 20 MIPS while hardware PWM peripherals drive H-bridge gates. The 5 V I/O directly drives common gate-driver and optocoupler thresholds used in industrial drives. Place the control ISR at fixed sample rate and use the DSP library's PID functions; a key performance consideration is servicing current feedback within one PWM period, which the 20 MIPS budget comfortably supports for low- to mid-power drives. For sensorless FOC of BLDC motors, step up to a higher-memory family member such as the dsPIC30F3012.
おすすめ
Embedded Prototyping and Education
The 18-pin PDIP (0.300 inch, 7.62 mm) package makes the DSPIC30F2011-20I/P uniquely friendly to breadboards, DIP sockets, and classroom labs - unlike its surface-mount siblings. Students and engineers can program it in-circuit with a low-cost PICkit2 or iCP02 (both listed as supported by PICcircuit's 18-pin adapter) using Microchip MPLAB. The 12 KB Flash is ample for teaching DSP concepts such as digital filtering and FFTs, while the 5 V supply matches classic lab benchtop setups. Use a 7805-style regulator module for power and keep decoupling capacitors (100 nF per VDD pin) close to the device for reliable ICSP programming.
おすすめ
Legacy Board Repair and Obsolescence Management
Many installed industrial and automotive-aftermarket boards were built around the dsPIC30F2011 in DIP or socketed form. Keeping DSPIC30F2011-20I/P inventory (distributors such as Heisener reported over 24,000 pieces in stock as of the data pull) protects serviceability of these systems. For eventual migration, Microchip documents seamless migration to dsPIC33F, PIC24H, or PIC24F devices in similar packages, and same-family drop-ins (dsPIC30F2012/3012) fit the same footprint with more headroom. When re-popping a socket, verify the speed-grade and temperature suffix on the replacement and reflash with the original firmware image via ICSP to restore function.
おすすめ
Battery-Powered and Portable Instruments
Handheld measurement instruments benefit from the DSPIC30F2011-20I/P's single-chip integration of control logic and DSP math, reducing component count versus MCU-plus-DSP two-chip solutions. Running from a single 5 V rail (or a boost converter from two cells), the 20 MIPS core executes real-time FFTs or RMS computations for metering displays. The Flash program memory supports calibration data updates in the field. Power budget should be managed with sleep modes between samples and by gating the oscillator during idle periods; consult document 70139b for current-consumption figures across clock configurations. The DIP package suits low-volume instrument assemblies using protoboard or socketed production PCBs.

設計ノート
The dsPIC30F family is a 5 V architecture per Microchip's product family description. Decouple each VDD pin with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a 4.7-10 uF bulk capacitor near the device. If interfacing with 3.3 V peripherals, add level shifting - 5 V logic levels can damage 3.3 V-only inputs. Verify exact VDD operating range and absolute maximum ratings in Microchip datasheet document 70139b before finalizing the power tree.
For the DIP package in socketed designs, use a machined-pin or dual-wipe socket for reliability in vibrating industrial environments. Keep the ICSP programming header (MCLR, VDD, VSS, PGD, PGC) wired directly to the chip with short traces; long RC filters on MCLR can block programming - use a 10k pull-up and a series resistor only if the programmer supports it. Route oscillator traces (OSC1/OSC2) short and away from switching nodes.
When substituting a same-family alternative (dsPIC30F2012/3012), always recompile firmware with the correct device selected in MPLAB - device ID and peripheral register maps differ between family members even though the pinout matches. Additionally, do not confuse speed grades: the '-20' suffix denotes 20 MIPS while '-30' parts run 30 MIPS; clock configuration fuses must match the speed grade. Confirm the '-I' industrial temperature rating (-40C to +85C) suits your enclosure conditions.
