PIC24FJ16GA002-E/SS Overview
A 16-bit microcontroller (MCU) is a microprocessor core with a 16-bit data path, 16-bit registers, and a 16-bit ALU, sitting in the product hierarchy between 8-bit MCUs (e.g., PIC16, AVR) and 32-bit MCUs (e.g., ARM Cortex-M, PIC32). The PIC24F series specifically targets low-power cost-sensitive applications through nanoWatt XLP technology, using on-the-fly clock switching, deep sleep modes, and peripheral activity monitors to extend battery life. PIC24F devices run a modified Harvard architecture with single-cycle 17-bit x 17-bit hardware multiply and 32/16-bit hardware divide, enabling deterministic real-time control.
Key features include 16 MIPS performance at 32 MHz, 16 KB Flash, 4 KB RAM, a 10-bit ADC with up to 13 channels and 500 ksps conversion rate, multiple Enhanced Capture/Compare/PWM (ECCP) modules, two UART, two SPI, and one I2C peripherals, five 16-bit timers, a real-time clock calendar (RTCC) with alarm, and a parallel master port for external memory expansion. The nanoWatt XLP technology provides sleep currents below 1 uA and a full-featured on-chip RTCC.
The MCU integrates a 2.5V/3.3V core, JTAG programming/debug interface, 5V tolerant I/O on most pins, and basic code-guard security. The Extended temperature grade (-E) supports -40C to +125C operation, making the part suitable for industrial and lighting control applications as referenced in Microchip's lighting application notes.
Typical applications include general-purpose embedded control, LED lighting systems, low-power sensor nodes, battery-powered instrumentation, automotive body and lighting subsystems, and human-machine interface (HMI) panels. The integrated RTCC and 13-channel 10-bit ADC make it well suited for HVAC, thermostat, and metering use cases.
When designing with this device, ensure the JTAG interface is accessible for in-circuit debugging, and provide adequate decoupling (100 nF + 10 uF) close to VDD/AVDD. The PIC24FJ family datasheet (DS39767) covers the entire sub-family, so always confirm the specific peripheral pinout for the 28-pin SSOP variant you are using.

Typical Applications
PIC24FJ16GA002-E/SS is suitable for 7 applications: General-Purpose Embedded Control, LED Lighting and Solid-State Lighting, Industrial Sensor and Metering, Automotive Body and Interior Electronics, Human-Machine Interface (HMI) Panels, HVAC and Thermostat Control, Low-Power Wireless Sensor Nodes.
General-Purpose Embedded Control
The PIC24FJ16GA002-E/SS fits general-purpose embedded control thanks to its 16 MIPS throughput at 32 MHz and 16 KB Flash, which comfortably hosts small control loops, GPIO toggling, and UART command parsing. The 4 KB RAM supports modest buffers for sensor logs and protocol framing without paging. The 28-SSOP footprint suits compact designs where board space is limited yet through-hole is undesirable. Five 16-bit timers and multiple ECCP + PWM modules handle brushed DC motor speed, fan control, and LED dimming. The 10-bit 500 ksps ADC on 13 channels streams analog feedback from thermistors, potentiometers, and current shunts. JTAG (TMS/TCK/TDO/TDI/PGExD3V6) supports in-circuit debugging and field firmware updates. Compared with a smaller PIC16, the 16-bit datapath improves DSP-style math without migrating to a 32-bit MCU.
Recommended
LED Lighting and Solid-State Lighting
The PIC24FJ16GA002-E/SS is recommended for LED lighting and solid-state lighting due to its nanoWatt XLP eXtreme Low Power technology, integrated RTCC with alarm for scheduling, and multiple PWM channels for dimming. PIC24F devices are explicitly recommended in Microchip lighting application notes for converting mains-powered LED fixtures into networked, dimmable, and color-tunable products. Sleep current below 1 uA with RTCC active minimizes standby consumption in always-on fixtures. The 13-channel ADC reads ambient light sensors and potentiometer color-temperature sliders, while the ECCP modules drive high-power LED strings via external MOSFET drivers. The Extended -40C to +125C grade handles thermally challenging enclosed fixtures and outdoor luminaires without derating firmware behaviour. Compared with discrete logic designs, the PIC24FJ integrates timer, RTC, and ADC into one IC.
Recommended
Industrial Sensor and Metering
The PIC24FJ16GA002-E/SS serves industrial sensor and metering nodes by combining the 10-bit 13-channel 500 ksps ADC, three on-chip analog comparators, and the Extended -40C to +125C operating temperature grade. The PIC24F core runs deterministic control loops for pressure, flow, and level measurement. LIN/UART-capable peripherals support fieldbus or RS-485 networks, while the RTCC with alarm schedules wake-up for periodic sampling. Compared with the PIC24F16KA family, this part offers larger Flash (16 KB vs 16 KB) and richer analog peripherals (3 comparators). The SSOP-28 package handles reflow soldering in automated production lines. The PIC24FJ's wide 2.0 V to 3.6 V supply range also enables direct operation from two AA cells for portable instrumentation.
Recommended
Automotive Body and Interior Electronics
The PIC24FJ16GA002-E/SS -E suffix qualifies as Extended temperature (-40C to +125C), and the PIC24F family is recommended by Microchip for automotive design into body and interior subsystems such as seat controllers, mirror adjusters, lighting modules, and HVAC vents. The LIN-capable UART provides slave connectivity to vehicle networks, while the 13-channel ADC reads switch panels, position sensors, and motor current. The nanoWatt XLP sleep modes are critical for quiescent-current-sensitive body electronics where battery drain is regulated. Compared with a discrete 8051 design, the PIC24FJ integrates timers, ADC, comparators, and UART to lower BOM count. Note that AEC-Q100 qualified variants require the VAO ordering code - the -E/SS suffix here targets industrial/automotive cabin applications.
Recommended
Human-Machine Interface (HMI) Panels
The PIC24FJ16GA002-E/SS handles HMI panels by driving character LCDs and reading capacitive touch / matrix keypads via the parallel master port and ECCP timers. 16 KB Flash accommodates bitmap tables and button mapping firmware, while 4 KB RAM supports small display buffers. The PIC24F core's deterministic single-cycle instruction execution simplifies scanning rates for 4x4 or 8x8 keypads and LED status indication. The SSOP-28 footprint suits handheld remote controls. Compared with 8-bit PIC16, the 16-bit datapath improves scan-loop performance and supports smoother LED fade via PWM. The RTCC with alarm enables wake-on-button events to extend battery life in remote controls.
Recommended
HVAC and Thermostat Control
The PIC24FJ16GA002-E/SS is suitable for HVAC and thermostat designs using its RTCC with alarm for scheduling, 13-channel ADC for reading thermistor temperature sensors, and multiple PWM channels for driving fan motors and damper actuators. The Extended temperature grade ensures reliable operation near heating equipment. nanoWatt XLP sleep currents below 1 uA make the part attractive for battery-backed thermostats that retain timekeeping across power outages. The PIC24F core runs PID loops in firmware to control setpoint accuracy. Compared with mechanical thermostats, this approach supports programmable schedules, remote sensors, and adaptive recovery algorithms. The parallel master port allows adding external SRAM for data logging.
Recommended
Low-Power Wireless Sensor Nodes
The PIC24FJ16GA002-E/SS drives battery-powered wireless sensor nodes thanks to nanoWatt XLP eXtreme Low Power technology with sub-1 uA sleep current and the RTCC alarm that wakes the core periodically to sample and transmit. The 2 UART modules interface to popular sub-GHz radios (MRF89XA) or 2.4 GHz transceivers (MRF24J40) via SPI. The 13-channel ADC reads multiple sensors (temperature, humidity, light) with the SSOP-28 footprint keeping board size minimal. Compared with a bare 8051 core, the PIC24F's peripheral-rich integration reduces external components. Deep-sleep + RTCC techniques can achieve years of life on a single AA battery pair when transmit duty-cycle is low.

- On-chip parallel master port for external memory expansion (vs PIC24F16KA102-E/SS)
- RTCC with alarm + 13-channel 10-bit ADC integrated (vs PIC24F16KM202-E/SO)
Design Notes
Power decoupling is mandatory for stable PIC24FJ operation. Place a 100 nF ceramic capacitor close to each VDD/VSS pin pair (pins 9/10 and 28/19 on the 28-SSOP package) and a 10 uF bulk capacitor on the supply rail. For analog precision, decouple AVDD/AVSS (pins 20/21) with a dedicated 100 nF capacitor; tie AVDD to VDD directly at the IC. nanoWatt XLP sleep current below 1 uA is only achievable if all peripherals are disabled and unused pins are configured as digital outputs driving low.
Keep the SSOP-28's JTAG/ICSP pins accessible - RB6/PGC and RB7/PGD are required for in-circuit programming and debugging. Route a 2x5 header or tag-connect footprint to a quiet area of the board away from high-current traces. The parallel master port pins (PMD/PMC) are muxed with PORTC; if PMP is not used, leave the PORTC bits as digital I/O. Avoid long traces on AVDD/AVSS - keep analog ground separated from digital ground until they meet at the bulk capacitor.
Common PIC24FJ pitfalls: (1) forget to disable peripherals before entering Sleep mode - the UART/SPI clocks prevent nanoWatt XLP currents; (2) misuse ECCP vs CCP - the Enhanced CCP supports PWM with dead-band control, which the basic CCP does not; (3) configure unused analog pins as digital outputs to prevent shoot-through on the ADC input mux; (4) do not exceed 3.6V on any I/O pin even if marked 5V tolerant - only specific pins support 5V input and the limits vary per port; (5) always set JTAGEN OFF in configuration bits if JTAG is unused, freeing pins for I/O.
Compliance Information
RoHS compliant per Microchip product page. The -E suffix denotes Extended temperature grade (-40C to +125C) but is NOT AEC-Q100 automotive qualified - automotive applications require specific VAO ordering codes. Halogen-free per Microchip RoHS/REACH disclosures.
