PIC24FJ128GA406T-I/MR

Microcontrollers Overview

The PIC24FJ128GA406T-I/MR is a 16-bit microcontroller from the PIC24FJGA4xx family, featuring 128 KB of Flash memory and 16 KB of RAM. It operates at up to 32 MHz (16 MIPS) with a supply voltage range of 2.0V to 3.6V. The device includes a 10/12-bit ADC with up to 16 channels, a 10-bit DAC, three comparators, and a Charge Time Measurement Unit. It supports USB On-The-Go functionality, cryptographic engines, and an LCD controller. The component is housed in a 64-pin QFN package.

Microcontrollers Feature Summary

• Supports dual-role USB On-The-Go operations for host or peripheral connectivity.
• Integrates a hardware cryptographic engine for AES, DES/3DES encryption and random number generation.
• Features extreme low-power modes including Deep Sleep and VBAT operation for minimal current consumption.
• Includes a dedicated LCD display controller capable of driving up to 64 segments by 8 commons.

Microcontrollers Applications

• Battery-powered portable devices requiring ultra-low power standby states
• USB-enabled consumer electronics and peripherals
• Industrial control systems utilizing capacitive touch sensing via CTMU
• Secure embedded applications leveraging on-chip cryptographic acceleration

Microcontrollers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the '-I' designation corresponds to the industrial temperature range specifications. Ensure the 'MR' package code matches the required 64-pin QFN footprint dimensions for your PCB layout. Cross-reference the datasheet revision to confirm pinout compatibility.

Microcontrollers Selection Notes

Select this model when 128 KB of program memory suffices for the application logic. Choose this variant over the GA410 or GA412 if the reduced I/O count and segment availability align with the design constraints. Consider the GB4xx series if specific USB power management pins are required instead of standard GPIO functions.

Microcontrollers Part Context

This component belongs to the PIC24FJGA4xx family, which unifies high-performance processing with extensive analog and communication peripherals. The family shares a common modified Harvard architecture and instruction set, allowing for code portability across different memory sizes and package options within the same series.
