DSPIC33FJ128GP310-I/PF

Microcontrollers Overview

The dsPIC33FJ128GP310-I/PF is a 16-bit Digital Signal Controller from the Microchip dsPIC33F General Purpose Family. It features a modified Harvard architecture CPU operating at up to 40 MIPS with a 16-bit data path and 24-bit instructions. The device includes 128 Kbytes of Flash program memory and 16 Kbytes of data RAM, packaged in a 100-pin TQFP. It supports industrial temperature ranges (-40°C to +85°C) and operates on a 3.0V to 3.6V supply voltage.

Microcontrollers Feature Summary

• Integrated 8-channel hardware Direct Memory Access (DMA) controller with dual-ported buffer area for peripheral-to-memory transfers without CPU cycle stealing.
• High-performance DSP engine featuring sixteen 16-bit general-purpose registers, two 40-bit accumulators with rounding/saturation, and single-cycle multiply-accumulate capabilities.
• Comprehensive communication suite including Enhanced CAN (ECAN), I2C, SPI, UART with LIN support, and Data Converter Interface (DCI) for codec applications.
• Flexible clock management system with integrated PLL, power-saving modes (Idle, Sleep, Doze), and fail-safe clock monitoring.

Microcontrollers Applications

• Speech and audio processing systems utilizing the DCI module.
• Industrial control applications requiring robust communication protocols like CAN and high-speed timers.
• Motor control implementations leveraging PWM and capture/compare modules.
• General-purpose embedded controllers needing significant I/O count and flash memory.

Microcontrollers Procurement Notes

Verify the specific suffix 'I/PF' corresponds to the Industrial temperature range and 100-pin TQFP package as documented in the official datasheet. Confirm that the ordering part number matches the exact memory size and peripheral configuration required for your design. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the latest revision history for any silicon errata or documentation updates before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a balance of moderate flash memory (128 KB) and high pin count (100 pins) is required within the dsPIC33F family. It is suitable for designs needing extensive digital I/O and multiple communication interfaces but do not require the higher performance or larger memory of the GP7xx or GP5xx series variants. Consider the TQFP package constraints for PCB layout.

Microcontrollers Part Context

This device belongs to the dsPIC33FJXXXGPX06/X08/X10 family of 16-bit Digital Signal Controllers. It shares the core CPU architecture and instruction set with other members of the General Purpose family, differing primarily in memory sizes, pin counts, and peripheral availability. The 'GP310' designation specifically identifies the 100-pin variant with 128 KB Flash and 16 KB RAM.

Microcontrollers Replacement Considerations

Direct substitutes within the same package and pinout include other devices from the dsPIC33FJ128GP3xx series, such as the dsPIC33FJ64GP310, provided memory requirements are met. For pin-compatible upgrades with more memory, consider the dsPIC33FJ256GP510, though peripheral configurations may vary. Always verify electrical characteristics and software compatibility before swapping.
