PIC24FJ64GP203-E/M5

Microcontrollers Overview

The PIC24FJ64GP203-E/M5 is a 16-bit microcontroller from the PIC24FJ64GP205/GU205 family, featuring 64 Kbytes of ECC Flash memory and 8 Kbytes of SRAM. It operates at up to 16 MIPS with a 32 MHz clock and supports a supply voltage range of 2.0V to 3.6V across an ambient temperature range of -40°C to +125°C. The device includes a 17-bit x 17-bit hardware multiplier, a 32-bit by 16-bit divider, and a 16-bit working register array. It provides up to 14-channel software-selectable 10/12-bit ADCs, three analog comparators, and five MCCP modules. Communication interfaces include two SPI ports, two I2C modules, and two UARTs.

Microcontrollers Feature Summary

• Features eXtreme Low-Power capabilities including Sleep, Idle, Doze modes, and retention sleep with an on-chip ultra low-power retention regulator for substantial power reduction.
• Includes functional safety peripherals such as a Fail-Safe Clock Monitor, Brown-out Reset, Programmable High/Low-Voltage Detect, and a Deadman Timer for safety-critical applications.
• Provides flexible Peripheral Pin Select (PPS) allowing independent I/O mapping of many peripherals, along with configurable interrupt-on-change on all I/O pins.
• Integrates a two-channel DMA controller to minimize CPU overhead and increase data throughput.

Microcontrollers Applications

• Low-pin count embedded systems requiring high-performance processing
• Applications needing robust functional safety features like fail-safe clock monitoring
• Battery-powered devices utilizing extreme low-power operating modes
• Systems requiring flexible peripheral pin mapping via PPS

Microcontrollers Procurement Notes

Verify the specific suffix 'E' against official Microchip documentation to confirm it denotes the industrial temperature grade (-40°C to +85°C) rather than extended (-40°C to +125°C), as datasheet tables list the base family temperature range without explicit suffix differentiation in the provided text. Confirm package type M5 corresponds to the 36-pin UQFN format shown in the pinout diagrams. Ensure ordering aligns with the non-USB GP variant specifications.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with 64 Kbytes of program memory is required in a compact 36-pin footprint. It is suitable for designs needing extensive analog inputs and multiple communication interfaces without USB OTG functionality. Consider the ECC Flash for enhanced data integrity and the availability of PPS for simplified PCB routing compared to fixed pin assignments.

Microcontrollers Part Context

This part belongs to the PIC24FJ64GP205/GU205 family of 16-bit eXtreme Low-Power Microcontrollers. The GP203 variant specifically excludes the USB On-The-Go module found in the GU203 counterpart, offering 36 pins and 27 I/O lines. It shares the same core CPU, memory sizes, and peripheral set as other members of the GP20x series, differing primarily in pin count and interface availability.

Microcontrollers Replacement Considerations

The PIC24FJ64GU203 serves as a direct functional substitute if USB OTG capability is required or desired, sharing identical pinouts and memory configurations. Other family members like the PIC24FJ64GP205 offer more I/O lines but require a larger package.
