PIC24FJ 16-bit Microcontroller Variants

Microchip PIC24FJ devices are 16-bit Flash microcontrollers with larger memory options, low-power modes, rich serial interfaces, USB on selected parts, and broad QFN/TQFP package coverage.

PIC24FJ Datasheet

Architecture

A middle path between 8-bit PIC simplicity and 32-bit MCU complexity.

Memory options

Supports larger application code and communication stacks.

Interface mix

Exact peripheral coverage depends on the selected PIC24FJ subfamily.

16-bit PIC control with larger memory and richer interfaces

Compare PIC24FJ variants by Flash size, RAM, package, interface set, analog resources, and power profile.

The PIC24FJ family gives Microchip customers a 16-bit step between 8-bit PIC controllers and 32-bit PIC32 devices. It is used when firmware needs more address space, more RAM, wider arithmetic, or richer communication peripherals while still keeping a deterministic MCU architecture and mature MPLAB development flow. Variants include compact 28-pin devices and larger 64-, 100-, and higher pin-count controllers with substantial Flash memory options.

PIC24FJ devices are common in industrial controls, metering, user-interface panels, portable instruments, data loggers, and communications modules. Depending on the exact part, the family can include multiple UART, SPI, I2C, USB, DMA, timers, input capture, output compare, ADC channels, comparators, RTCC, and low-power sleep modes. Substitution should check peripheral pin select, oscillator options, programming/debug pins, Flash/RAM size, operating voltage, package, and temperature grade.

  • 16-bit architecture for firmware larger than typical 8-bit control tasks
  • Broad Flash and pin-count options for scalable product designs
  • Rich serial, timer, analog, and DMA resources on selected devices

Ordering Code Differences

How suffixes on PIC24FJ map to package, grade, and reel options.

[{"code":"PIC24FJxxxGA","meaning":"General-purpose PIC24FJ groups with varying Flash, pin count, and peripheral sets."},{"code":"PIC24FJxxxGB","meaning":"Often identifies variants with USB or richer connectivity; verify exact interface support."},{"code":"I or E markers","meaning":"Temperature or grade markers depending on the exact Microchip ordering code."},{"code":"ML, PT, MR, BG style suffixes","meaning":"Package and packing identifiers such as QFN, TQFP, or BGA options."}]

How to Choose the Right PIC24FJ Microcontrollers

💡

Size RAM as well as Flash

Communication stacks, buffers, USB, and display code can consume RAM quickly on 16-bit MCUs.

💡

Check peripheral pin select

PPS flexibility helps routing, but exact pin availability still depends on package and device.

💡

Validate low-power modes

Sleep current, wake sources, RTCC behavior, and oscillator startup affect battery-life claims.

Frequently Asked Questions

Common technical questions about the PIC24FJ product family.

PIC24FJ is a better fit when firmware size, RAM needs, 16-bit processing, DMA, or richer interfaces exceed what an 8-bit PIC18F design can comfortably support.
Not automatically. They can differ in USB support, memory, package, peripheral set, and pin assignments.
Sometimes for lower-complexity designs, but PIC32MX is a 32-bit MCU. Compare performance, peripherals, memory, toolchain, and firmware architecture before changing families.
