PIC24HJ128GP206-I/PT

Microcontrollers Overview

The PIC24HJ128GP206-I/PT is a 16-bit microcontroller from the PIC24H family, featuring a modified Harvard architecture with a 16-bit data path and 24-bit instructions. It operates at up to 40 MIPS within a 3.0V to 3.6V supply range across industrial temperatures (-40°C to +85°C). The device includes 128 KB of Flash program memory and 8 KB of RAM (including 2 KB DMA RAM). Key peripherals include an Enhanced CAN module, two UARTs, two SPIs, two I2Cs, eight input capture channels, eight output compare channels, and an 18-channel 10-bit/12-bit ADC.

Microcontrollers Feature Summary

• Integrated Enhanced CAN (ECAN) module supporting DeviceNet addressing and FIFO mode via DMA for robust communication.
• Hardware Direct Memory Access (DMA) controller with dual-ported buffer enabling peripheral-to-memory transfers without CPU intervention.
• Flexible clock system with integrated PLL and low-jitter oscillator options for precise timing control.
• Comprehensive analog interface with auto-scanning capabilities and multiple trigger sources for synchronized conversions.

Microcontrollers Applications

• Industrial motor control systems requiring deterministic interrupt handling and high-speed computation
• Automotive networks utilizing CAN bus protocols and DeviceNet addressing support
• Data acquisition systems leveraging multi-channel ADC with hardware scanning and DMA transfer

Microcontrollers Procurement Notes

Verify the specific suffix '-I/PT' corresponds to the industrial temperature range and TQFP package. Confirm pinout compatibility if migrating from other PIC24H variants. Check for any applicable errata sheets regarding silicon revisions before finalizing design implementation.

Microcontrollers Selection Notes

Select this component when 128 KB of program memory and 8 KB of RAM are sufficient for the application logic. Ensure the 64-pin TQFP package fits the board layout constraints. Verify that the required number of I/O pins and specific peripheral instances (e.g., single ECAN module) match the project requirements compared to higher-capacity siblings.

Microcontrollers Part Context

This part belongs to the PIC24HJXXXGPX06/X08/X10 family, which shares pinouts and core architecture with dsPIC33F devices. It offers a migration path from 8-bit PICs or earlier 16-bit families while maintaining software compatibility with the broader PIC24/dsPIC ecosystem through shared instruction sets and peripheral modules.
