Key Features
- 40 MHz 16-bit DSP core with hardware barrel shifter and floating-point support accelerates real-time control algorithms without an external math coprocessor
- 128 KB on-chip flash and 8 KB RAM provide ample program and data storage for mid-complexity motor control and power conversion firmware
- JTAG boundary scan interface enables in-circuit debugging and production test without dedicated test-access hardware
- 28-pin QFN package (4 mm × 4 mm) minimizes PCB footprint while exposing a full complement of PWM, ADC, and communication peripherals
Applications
The DSPIC33FJ128GP802-I/MM is a natural fit for single- and three-phase motor control inverters, digital power supplies, and solar micro-inverters where real-time DSP computation and multiple PWM channels must coexist on one chip. Its hardware DSP engine handles PID loop execution in under 1 µs, supporting switching frequencies up to 100 kHz in AC drive and power factor correction designs. The compact 28-pin QFN also suits space-constrained servo drives and intelligent sensor nodes that require both floating-point processing and on-chip ADC sampling.

Frequently Asked Questions
What maximum clock frequency does the DSPIC33FJ128GP802-I/MM support, and how does that affect real-time control loop timing?
The DSPIC33FJ128GP802-I/MM runs at up to 40 MHz (20 MIPS), executing a single-cycle 16-bit multiply-accumulate operation in 25 ns. For a typical digital PID motor control loop with 50 DSP instructions, the full loop completes in approximately 2.5 µs, supporting PWM carrier frequencies up to 100 kHz with sufficient computational margin for current sensing and commutation logic.
How much on-chip flash and RAM does the DSPIC33FJ128GP802-I/MM provide, and what does that mean for firmware complexity?
The device integrates 128 KB of program flash and 8 KB of data RAM. At a typical embedded C code density of 4 KB per functional module, the 128 KB flash accommodates 30 or more firmware modules—enough for a full motor drive application including communication stacks, fault logging, and parameter storage without external memory. The 8 KB RAM supports 4 independent 1 KB real-time data buffers for ADC sample queues and communication frame buffers.
For a compact servo drive PCB, how does the 28-pin QFN package size affect layout and thermal management at 40 MHz?
The 28-pin QFN measures 4 mm × 4 mm with a 0.5 mm lead pitch and an exposed thermal pad, dissipating approximately 200 mW at 40 MHz from a 3.3 V supply. Connecting the thermal pad to a 4-via copper pour of 25 mm² limits junction temperature rise to under 10 °C above ambient at 25 °C, and the small footprint leaves space for gate-driver ICs within a 30 mm × 40 mm servo drive PCB.
