PIC24FJ64GA102-I/SO

Microcontrollers Overview

The PIC24FJ64GA102-I/SO is a 16-bit microcontroller from the PIC24FJ64GA104 family, featuring 64 KB of Flash program memory and 8 KB of SRAM. It operates at up to 32 MHz (16 MIPS) with an operating voltage range of 2.0V to 3.6V. The device includes a 10-bit ADC with up to 10 channels, three analog comparators, and a Charge Time Measurement Unit (CTMU). Key peripherals include two I²C modules, two UARTs, two SPI modules, five 16-bit timers, and a Parallel Master Port (PMP). It utilizes nanoWatt XLP technology for power management.

Microcontrollers Feature Summary

• Incorporates nanoWatt XLP technology with selectable power modes including Deep Sleep, Idle, and Doze modes for optimized energy efficiency.
• Features Peripheral Pin Select (PPS) allowing independent mapping of digital peripheral inputs and outputs to various I/O pins.
• Includes a hardware Real-Time Clock/Calendar (RTCC) module that provides clock, calendar, and alarm functions even in Deep Sleep mode.
• Supports self-reprogramming under software control via In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD).

Microcontrollers Applications

• Battery-powered portable devices requiring low-power operation
• Industrial control systems utilizing serial communication protocols
• Capacitive touch sensing applications using CTMU interface
• General-purpose embedded control applications

Microcontrollers Procurement Notes

Verify the specific package type and temperature grade suffixes against official Microchip documentation before procurement. Ensure compatibility with development tools such as MPLAB IDE and programming hardware like PICkit or REAL ICE. Confirm that the selected component meets all environmental and electrical specifications required for the target application design.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture is required with moderate memory capacity and extensive peripheral flexibility. Consider the PIC24FJ64GA102-I/SO for designs needing remappable pins and multiple serial interfaces within a 28-pin footprint. Evaluate power consumption requirements against the available nanoWatt XLP modes to ensure optimal battery life for portable implementations.

Microcontrollers Part Context

This part belongs to the PIC24FJ64GA104 family, which shares identical features across different memory sizes and pin counts. The 64KB Flash variant offers expanded code storage compared to the 32KB version while maintaining the same peripheral set. The family ensures easy migration between devices through consistent pinouts and instruction sets, supporting scalable application development.

Microcontrollers Replacement Considerations

The PIC24FJ32GA102-I/SO serves as a direct substitute if reduced program memory is acceptable. Other members of the PIC24FJxxGA10x family may also be compatible depending on specific memory and pin requirements.
