DSPIC33FJ128GP802T-I/SO - 16-bit DSC 40 MIPS 128KB Flash | Microchip

The Microchip Technology DSPIC33FJ128GP802T-I/SO is a 16-bit Digital Signal Controller (DSC) from the dsPIC33FJ family delivering 40 MIPS performance, 128KB (128K x 8) of Flash program memory, and 16KB of SRAM, housed in a 28-pin SOIC (7.50mm width) surface-mount package with industrial temperature rating (-40C to +85C) and 3V to 3.6V supply operation. A Digital Signal Controller combines the compute architecture of a digital signal processor with the peripheral set and ease of use of a microcontroller. Within the embedded hierarchy, the DSC sits between general-purpose MCUs and dedicated DSPs: it executes single-cycle MAC (multiply-accumulate) instructions with dual operand fetches like a DSP, while retaining flash memory, interrupts, and rich analog peripherals typical of an MCU. The dsPIC33F family is Microchip's mainstream 16-bit DSC line. Key features include a modified Harvard, 16-bit RISC core with DSP engine, 8-channel DMA controller for data-intensive streaming, up to two 3.3V UARTs, SPI and I2C peripherals, a 10-bit ADC with up to 1.1 Msps throughput, and flexible output-compare/input-capture modules for motor control and PWM generation. In-circuit serial programming (ICSP) via the PGD/PGC pins simplifies field updates. Architecturally, the device executes 40 MIPS from an internal PLL driven by the on-chip fast RC or external crystal oscillator. The MAC instruction fetches two operands from memory while multiplying two W registers and accumulating the result in a single cycle, which is central to FIR/IIR filtering and FFT workloads. The GP (General Purpose) variant emphasizes analog and communication peripherals over the motor-control (MC) variant. Typical applications include digital power supplies, LED lighting control, audio signal processing, sensor conditioning, industrial automation nodes, and graphical LCD interfaces - a documented public project drives a 320x240 PG320240H-P9 graphical LCD directly from this part. Design consideration: the 3V-3.6V supply rail is strict; provide local decoupling (100nF per VDD pin plus bulk capacitance) and keep AVDD/AVSS paired with VDD/VSS for ADC accuracy.
