PIC24FJ16GA002-E/SP Présentation
A 16-bit microcontroller is a microprocessor that operates on 16-bit-wide data words, instructions, and registers, sitting in a hierarchy between 8-bit MCUs (e.g., PIC16, AVR) and 32-bit MCUs (e.g., PIC32, ARM Cortex-M). The PIC24F family uses Microchip's nanoWatt eXtreme Low Power technology to deliver 16 MIPS at 3.3V while consuming only a few mA active and sub-uA in sleep, which is why PIC24F is broadly used in battery-powered and always-on embedded designs.
Key features of this part include a 16 MIPS CPU with single-cycle hardware 17x17 multiply and 32/16-bit hardware divide, a 10-bit ADC up to 500 ksps with up to 13 input channels, multiple PWM/OC outputs, I2C/SPI/UART peripherals, a Real-Time Clock/Calendar, and 5V-tolerant digital I/O. The 28-SPDIP footprint simplifies breadboarding, hand-soldered prototypes, and legacy board replacements where through-hole retention is required.
The PIC24FJ16GA002-E/SP is widely deployed in industrial sensor interfaces, low-power data loggers, automotive interior accessories (per Microchip's recommended-for-automotive-design note on the family page), medical instrumentation, and any application where a 5V-tolerant 16-bit MCU with extended-temperature rating is required in a DIP form factor. Designers moving from PIC16F to PIC24F retain code compatibility with Microchip's MPLAB X IDE and XC16 compiler toolchain.
When designing with this part, note that the -E grade supports the extended -40C to +125C range versus the -I grade (-40C to +85C); choose -E only if the application actually demands it, since -E parts carry a small price premium. Program/debug is supported via ICSP on pins 1 (PGECx) and 28 (PGEDx), and an external 32.768 kHz crystal is recommended for RTC accuracy.

Applications typiques
PIC24FJ16GA002-E/SP convient pour 7 applications: Industrial Sensor Interface Boards, Battery-Powered Data Loggers, Automotive Interior Accessories, Medical Monitoring Devices (Non-Safety), Consumer Appliance Control Panels, Educational and Hobbyist Development, HVAC Building Automation Nodes.
Industrial Sensor Interface Boards
The PIC24FJ16GA002-E/SP's 10-bit ADC (up to 500 ksps with up to 13 analog channels), 16 MIPS core, and 4KB SRAM make it well suited for industrial sensor aggregation nodes that read multiple analog inputs from temperature, pressure, and flow sensors. Its 28-SPDIP through-hole package simplifies hand-rework in factory-floor installations where vibration resistance matters. The nanoWatt extreme low-power modes extend battery life on wireless sensor transmitters. RTCC with external 32.768 kHz crystal supports accurate timestamping for industrial logging protocols.
Recommandé
Battery-Powered Data Loggers
The PIC24FJ16GA002-E/SP's nanoWatt extreme low-power technology and 4KB SRAM deliver months of operation from a single cell when configured in deep sleep. With 16KB Flash and 4KB RAM, the device can buffer sensor readings locally between wake cycles, writing blocks to external EEPROM or SPI Flash. The RTCC enables time-stamped event recording while consuming only microamps. The 28-SPDIP package also accepts standard battery-pack sockets, simplifying prototype swapping during field trials.
Recommandé
Automotive Interior Accessories
Microchip lists the PIC24FJ16GA002 family as recommended for automotive design, and the -E/SP grade's -40C to +125C rating covers cabin and under-hood-adjacent environments. The 16 MIPS core runs CAN/LIN stacks via external transceivers (e.g., MCP2515 for CAN), and the device's 5V-tolerant digital I/O interfaces directly with automotive switch panels and LED drivers. Engineers should request the AEC-Q100 VAO automotive-grade ordering code for production deployments, but the -E grade is acceptable for non-safety interior modules.
Recommandé
Medical Monitoring Devices (Non-Safety)
The PIC24FJ16GA002-E/SP's deterministic 16 MIPS performance and 16KB Flash are sufficient for non-implantable, non-life-support medical peripherals such as pill dispensers, portable nebulizers, and home-health telemetry hubs. The 10-bit ADC reads sensor data from airflow, weight, and motion inputs, while UART/SPI interfaces connect to Bluetooth or Wi-Fi modules for cloud uplink. The extended temperature grade ensures operation in sterilized or refrigerated environments.
Recommandé
Consumer Appliance Control Panels
With up to 19 general-purpose I/O, PWM outputs for LED or motor brightness, and a 10-bit ADC for front-panel potentiometers, the PIC24FJ16GA002-E/SP is a fit for washing-machine user interfaces, microwave keypads, and air-conditioner control boards. The 28-SPDIP package eases assembly at appliance OEMs that prefer through-hole retention against vibration. Hardware 17x17 multiply accelerates filter math for sensor smoothing in compressor control loops.
Recommandé
Educational and Hobbyist Development
The 28-SPDIP package's 0.1" pin pitch fits standard solderless breadboards and 28-pin DIP sockets, making the PIC24FJ16GA002-E/SP a popular choice for university embedded courses and hobbyist projects transitioning from PIC16F. The 16 MIPS performance supports introductory RTOS concepts, while UART/SPI/I2C peripherals let students interface sensors, displays, and actuators with no extra hardware. PICkit 4 or MPLAB Snap programmers connect directly via ICSP for in-circuit debug.
Recommandé
HVAC Building Automation Nodes
The PIC24FJ16GA002-E/SP's extended-temperature range and 28-SPDIP mechanical strength suit rooftop and basement HVAC controller sub-boards. Its 10-bit ADC handles multiple thermistor inputs for zone temperature sensing, while PWM outputs drive damper servos and fan-speed controllers. UART links to BACnet or Modbus gateways, and the device's sleep current under 1 uA (RTCC running) makes it ideal for battery-backed wireless thermostats that must survive multi-year deployments.

Principaux différenciateurs
- Extended -40C to +125C operating range vs Industrial grade (vs PIC24FJ16GA002-I/SP)
- Through-hole 28-SPDIP package for hand-soldered and high-vibration designs (vs PIC24FJ16GA002-E/ML)
- Larger 16KB Flash vs base PIC24F variants in same pin count (vs PIC24FJ08GA002-E/SP (hypothetical lower-density family member))
Notes de conception
Power the PIC24FJ16GA002-E/SP from a 3.3V rail within the 2.0V to 3.6V VDD range. Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 20) and another between AVDD (pin 17) and AVSS (pin 16) for ADC noise rejection. For battery applications, the nanoWatt extreme low-power technology lets the part enter Sleep or Deep Sleep modes drawing sub-uA while keeping the RTCC running; verify wake-up sources (INT0, RTCC alarm, etc.) are configured before relying on low standby current.
For 28-SPDIP layouts, ensure 0.1" (2.54 mm) pin pitch plated through-holes with at least 0.6 mm drill to ease hand-soldering. Keep crystal traces (OSC1/OSC2, pins 9-10) short and symmetric; use a ground guard ring around the 32.768 kHz crystal if RTCC accuracy is required. Route the ICSP lines (PGEC1 on pin 1, PGED1 on pin 28) so a 6-pin header can be added without crossing signal traces, enabling in-circuit debug on production boards.
Do not connect 5V directly to VDD; the supply must stay within 2.0V to 3.6V, although the digital I/O pins are 5V-tolerant when VDD is in spec. Pin 1 is MCLR; leave the MCLR pull-up enabled in firmware defaults and only reconfigure as a GPIO if you accept the loss of the external reset function. For ADC accuracy, avoid toggling digital I/O on adjacent pins during conversions, or insert a 100 ns settling delay before the ADC acquisition window. The Extended (-E) temperature grade adds cost; do not select it unless the application requires operation above +85C.
Separate analog (AVDD/AVSS, AN0-AN12) from digital (VDD/VSS, RA/RB) planes with a single-point connection to avoid digital switching noise coupling into ADC readings. If the 28-SPDIP part sits on a board with switching regulators, place the MCU on the opposite side of the PCB with a ground split between analog and digital domains, joined under the AVDD/AVSS pins. For SPI/I2C buses running above 1 MHz, add 4.7k to 10k pull-ups on I2C lines and series 33 ohm terminations on SPI clock and data lines.
Informations de conformité
Per third-party compliance data, the PIC24FJ16GA002 family is halogen-free. Standard -E/SP part is not AEC-Q100 qualified; request Microchip's VAO automotive ordering code for AEC-Q100 / PPAP documentation. Family flagged with estimated EOL ~2026 - verify last-time-buy status with Microchip for long-term production planning.
