MPN: PIC24F16KL402-I/SS ✓ פעילPIC24F16KL402-I/SS סקירה
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.

הערות תכנון
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.
