PIC24F16KL402-I/SS Visão geral
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, peripherals, and I/O. The 16-bit PIC24F family sits between 8-bit PIC18 devices and 32-bit PIC32 parts in Microchip's portfolio, offering a balance of low cost, low power, and higher code density for C-based firmware. The 'KL' sub-series is the low-pin-count, low-power branch aimed at consumer, medical, and portable safety/security products.
Key features include a 10-bit, up to 12-channel A/D converter with 500 ksps conversion rate and Sleep/Idle-mode sampling, dual rail-to-rail analog comparators with programmable I/O, an on-chip voltage reference, three 16-bit timers, a 16-bit Capture/Compare/PWM (ECCP) module, an MSSP peripheral supporting both I2C and SPI, and up to 25 general-purpose I/O pins. The nanoWatt XLP technology enables currents below 1.8 µA in Sleep mode with RTCC and 30 nA in deep Sleep. According to the Microchip PIC24F16KL402 Family Data Sheet, the device supports ICD (In-Circuit Debug) via dedicated PG/RE pins and operates across -40 °C to +85 °C industrial temperature range.
Typical applications include low-cost medical disposables (testers, dispensers, inhalers), portable consumer electronics (media players, GPS accessories, cell phone peripherals, electronic toys and games), safety/security sensors, battery-powered sensor nodes, and home appliances. The wide peripheral mix allows designers to migrate existing PIC18 firmware while gaining 16-bit performance.
When designing with this part, plan for a 3.3 V core supply, place 0.1 µF decoupling near each VDD pin, and connect the exposed pad (where present) to the ground plane for thermal relief. The MSSP can be configured for either I2C or SPI but not both simultaneously; firmware must select one mode at runtime.

Low-Cost Medical Disposables
The PIC24F16KL402-I/SS suits disposable medical devices like single-use glucose testers, asthma inhalers, and pill dispensers where the XLP Sleep current below 1.8 µA extends coin-cell battery life beyond the shelf life of the consumable. Its 16-bit core supports accurate ADC processing for diagnostic sensors. The 28-SSOP keeps BOM under $3 in volume.
Recomendado
Portable Consumer Electronics
The PIC24F16KL402-I/SS powers portable media players, GPS peripherals, cell phone accessories, and electronic toys/games where cost and battery life dominate the BOM. The 16 MIPS performance decodes audio frames in real time, while the 12-channel 10-bit ADC reads buttons and battery telemetry. XLP Sleep modes let the MCU spend 99% of the time idle.
Recomendado
Safety and Security Sensors
The PIC24F16KL402-I/SS fits low-power PIR motion sensors, smoke alarms, and home security peripherals where standby current is critical to multi-year battery life. XLP deep Sleep below 30 nA keeps a 3 V coin cell alive for 10+ years. The dual analog comparators allow direct interfacing to PIR thermopiles and smoke-chamber amplifiers without extra ICs.
Recomendado
Battery-Powered Sensor Nodes
Industrial IoT edge sensors using the PIC24F16KL402-I/SS leverage the MSSP I2C/SPI interface to read digital sensors like temperature, humidity, and accelerometers. The 16 KB Flash accommodates MQTT/HTTP or LoRaWAN stack fragments on small TCP networks. Sleep currents below 1.8 µA enable multi-year battery deployments on 2xAA cells.
Recomendado
Home Appliance Control
The PIC24F16KL402-I/SS drives user-interface and timing tasks in small home appliances like coffee makers, kitchen timers, and air-quality monitors. The 16-bit ECCP module controls brushed DC motors and dimming LEDs. nanoWatt XLP architecture keeps standby power below 0.1 W, helping designs comply with EU standby regulations.
Recomendado
In-Circuit Debug-Ready Prototyping
The PIC24F16KL402-I/SS supports MPLAB ICD via dedicated PG/RE pins on the 28-SSOP footprint, making it ideal for engineering prototypes and educational designs. The standard 0.65 mm SSOP pitch is breadboard-compatible via SSOP-to-DIP adapter PCBs. Combined with MPLAB X IDE and XC16 compiler, designers get a 16-bit upgrade path with minimal toolchain change.

Notas de projeto
Estimated: at VDD=3.3V, CPU at 32 MHz / 16 MIPS, typical run current is ~4-5 mA; at Sleep with RTCC and WDT, XLP technology drops the current to ~1.8 µA. Place a 0.1 µF X7R decoupling capacitor within 5 mm of each VDD pin and a 10 µF bulk electrolytic or tantalum at the board's power entry. Configure the lowest-frequency oscillator needed by the design and disable unused peripherals in firmware to extend battery life.
The 28-SSOP uses a 0.65 mm pitch; route power and ground on inner planes to provide low-impedance references. Keep the analog AVSS / AGND pins tied to a clean ground plane, isolated from noisy digital returns. Place the ICD PG/RE pins at the edge of the board or on test-point pads accessible by the MPLAB ICD header for prototype bring-up; do not place resistors in series with PGD1 or PGC1 in production unless they are bypassed with 0 ohm jumpers.
Do not exceed 3.6 V on VDD; transients above 4 V can permanently damage the MCU. Always configure unused I/O as outputs driving low to minimize current draw. The MSSP can be either I2C or SPI - not both - so the firmware must select the desired mode and clock polarity at runtime. ADC accuracy depends on the on-chip voltage reference; for highest precision use the external CVREF pin or an external precision reference.
On 28-SSOP layouts, keep digital traces away from the analog AVCC / AVSS pair, especially around AN4-AN12. Use a guard trace or ground island if the analog inputs handle low-level sensor signals (<10 mV). For I2C, use 4.7 kΩ pull-up resistors at 100 kHz, or 2.2 kΩ for 400 kHz Fast Mode. For noise-immune UART RS-485 designs, add series ferrite beads on the bus lines and a TVS diode for surge protection.
