MPN: PIC24F16KA102-E/SS ✓ Hoạt độngPIC24F16KA102-E/SS Tóm tắt
A PIC microcontroller (Microcontroller Unit, MCU) is a single integrated circuit that contains a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and a wide range of on-chip peripherals such as timers, ADC, communication interfaces, and I/O ports. The PIC24F sub-family uses Microchip's 16-bit modified Harvard architecture with a 16-bit data path and 24-bit instruction wordwidth, positioned between the 8-bit PIC16/PIC18 families and the high-performance dsPIC/PIC32 lines. Within the power-management hierarchy, XLP nanoWatt MCUs target battery-powered and energy-harvesting applications where deep sleep current (in nanoamps) and fast wake-up time dominate the design envelope.
Key features include deep sleep mode with DSBOR and DSWDT supervision, RTCC with on-chip calibration for real-time clock operation without a crystal, a 9-channel 10-bit ADC, two analog comparators, up to three UART/SPI/I2C peripherals, and five 16-bit timers. Sleep currents are typically under 50 nA in deep sleep with full RAM retention, allowing years of operation from a CR2032 coin cell. The internal 8 MHz oscillator is factory-calibrated to within 2% across the full temperature range, eliminating the external crystal on many designs.
The PIC24F16KA102-E/SS combines ultra-low-power nanoWatt XLP technology with a 16 MIPS CPU core and 16 KB self-programmable Flash. The peripheral set is shared across the entire PIC24F16KA1xx family (PIC24F08KA101, PIC24F16KA101, PIC24F08KA102, PIC24F16KA102), so code developed on the 28-pin SSOP version is portable to 20-pin variants in the same family. Code-protect and ICSP (In-Circuit Serial Programming) are supported over the standard two-wire PGx/PGx interface.
Typical applications include battery-powered sensors, wearable health monitors, remote controls, energy-harvesting devices, low-cost consumer products, and industrial sensor nodes. The wide 1.8 V to 3.6 V operating range suits single-cell lithium coin-cell designs as well as 2x AA alkaline systems. The internal oscillator and 5-channel hardware PWM make the part a good fit for direct LED-driving or low-end motor-control tasks.
When designing with this part, enable the DSBOR and DSWDT deep-sleep supervisors if the application may experience brown-out conditions or firmware lock-up during long unattended battery operation. Pin-out usage of the MCLR pin is mandatory as a programming/debug entry point; leave it accessible in the PCB layout even if no external reset is wired.

Ứng dụng tiêu biểu
PIC24F16KA102-E/SS phù hợp cho 7 Áp dụngs: Battery-Powered IoT Sensor Node, Wearable Health Monitor, Industrial Sensor and Field Transmitter, Remote Control and Consumer HMI, Energy-Harvesting Device, Low-End Motor Control / LED Driver, Smart Home and Home Automation Hub.
Battery-Powered IoT Sensor Node
The PIC24F16KA102-E/SS is well matched to coin-cell-powered wireless sensor nodes because its deep sleep current stays below 50 nA with full RAM retention, while the 16 MIPS core wakes in microseconds to service a sensor reading. Powered from a CR2032 (3 V) or 2x AA alkaline, the part can sustain years of operation when duty-cycled to <1% active time. The 9-channel 10-bit ADC handles temperature, light, and analog sensor front-ends, and the three UART/SPI/I2C peripherals can host a low-energy radio such as a sub-GHz transceiver or BLE module via a UART command interface. The 1.8 V to 3.6 V supply range matches both primary cells and single-cell LiFePO4 chemistries without an extra LDO. Pin-compatible PIC24F16KA101 variants allow code reuse across product tiers that need only 8 KB Flash.

Wearable Health Monitor
Wearable fitness bands and medical patches benefit from the PIC24F16KA102-E/SS's 16 MIPS performance combined with sub-microamp sleep currents, which together enable continuous heart-rate or SpO2 sampling while preserving multi-day battery life. The 10-bit ADC with up to 9 channels can read optical photodiode signals from a PPG front-end, and the on-chip analog comparators allow low-latency threshold detection without waking the CPU. RTCC retained in sleep keeps wall-clock time accurate enough for time-stamping samples, removing the need for an external RTC chip. The SSOP-28 footprint is small enough for sub-20 mm wearables, and the -E/SS variant's 125C rating survives body-heat and reflow stresses. Recommended companion: a low-noise LDO from Microchip's MIC33 family and a CR2032 or small LiPo battery.

Industrial Sensor and Field Transmitter
Industrial 4-20 mA loop-powered transmitters and factory sensor nodes use the PIC24F16KA102-E/SS because its -40C to +125C extended industrial temperature range survives harsh control-cabinet environments. The 16 MIPS core is fast enough to run C-based protocol stacks such as IO-Link or HART-modem interfaces, while the deep sleep currents keep average consumption low enough to operate from a 4 mA loop budget. On-chip EEPROM (512 B) provides non-volatile calibration storage, eliminating external memory. The 9-channel ADC interfaces directly to bridge sensors and RTDs using a low-cost op-amp front end, and the SSOP-28 footprint gives the layout engineer room for both analog and digital ground planes in a compact DIN-rail enclosure.

Remote Control and Consumer HMI
Universal remote controls, BLE smart-home keyfobs, and consumer HMIs are cost-sensitive applications where the PIC24F16KA102-E/SS shines because it integrates 16 KB Flash, 1.5 KB RAM, and 512 B EEPROM in a single chip, reducing external parts count. The 16 MIPS core is sufficient for driving an LCD segment display and scanning a keypad matrix in real time, while deep sleep current under 50 nA means a single cell survives years of standby. The three UART/SPI/I2C peripherals can interface to BLE, NFC, or sub-GHz modules and to a segment LCD controller. The SSOP-28 footprint is friendly to slim, hand-held enclosures and is compatible with the same-family PIC24F16KA101 for cost-reduced SKUs with 8 KB Flash.

Energy-Harvesting Device
Solar, vibration, and thermal energy-harvesting devices demand the lowest sleep currents on the market, and the PIC24F16KA102-E/SS's nanoWatt XLP deep sleep under 50 nA with full RAM retention is well below the leakage budget of a typical harvester output. The 1.8 V to 3.6 V supply range allows direct connection to a small supercapacitor or thin-film battery without an extra regulator. The on-chip 8 MHz calibrated internal oscillator eliminates the external crystal, and the fast wake-up from deep sleep lets the device accumulate tiny energy packets efficiently. A PIC24F16KA101 variant can be substituted in the same SSOP-28 footprint for designs that need only 8 KB Flash, lowering cost while preserving all low-power characteristics.

Low-End Motor Control / LED Driver
Small BLDC fans, micro-pumps, and constant-current LED string controllers fit the PIC24F16KA102-E/SS because the 16 MIPS core can run a sensorless commutation algorithm or PWM dimming loop while five 16-bit timers provide flexible PWM channels. The SSOP-28 footprint keeps the BOM compact and allows direct gate-driver interface to FET bridges. The extended -40C to +125C rating covers under-hood automotive lighting and industrial LED fixtures. The 16 KB Flash supports modern C-based firmware with USB or CAN stacks if needed via external transceiver, while the 512 B EEPROM stores calibration and trim values. For cost-reduced SKUs the same-footprint PIC24F08KA101 family members provide pin-compatible lower-Flash variants.

Smart Home and Home Automation Hub
Smart-home hubs, thermostats, and wireless sensor bridges benefit from the PIC24F16KA102-E/SS because the 16 MIPS core can run Zigbee or sub-GHz host stacks while the XLP deep sleep keeps idle current under 50 nA. The 1.8 V to 3.6 V supply range allows direct battery or USB-power operation. The SSOP-28 footprint supports compact wall-mount enclosures, and the same-footprint PIC24F16KA101 family enables tiered SKUs from 16 KB Flash down to 8 KB Flash without PCB rework. The on-chip RTCC provides accurate wall-clock timing for scheduling events, and the 9-channel 10-bit ADC can read temperature and humidity sensors directly.

Ghi chú thiết kế
Estimated: deep sleep current <50 nA at 3.3 V means a CR2032 coin cell (220 mAh) can power the PIC24F16KA102-E/SS for ~5 years if the active duty cycle stays under 0.1%. Always enable DSBOR and DSWDT in firmware if the application may be unattended for long periods, since brown-out recovery from a depleted cell without DSBOR can corrupt Flash. Decouple VDD with a 100 nF ceramic placed within 5 mm of the pin, and add a bulk 1 uF to 10 uF for pulsed loads during ADC sampling.
Route the MCLR pin directly to a programming header even if no external reset is wired, because ICSP uses MCLR/VPP as the high-voltage programming entry point. Keep the analog and digital grounds as separate nets joined at a single point near the VSS pin. Place the ICSP PGC/PGD traces as a short differential pair and avoid routing them under switching nodes. SSOP-28 is a fine-pitch package; design the land pattern to the IPC-7351 nominal standard with 0.30 mm leads on 0.65 mm pitch, and add solder-mask slivers between pads.
Do not assume MCLR can be left open in production. The internal pull-up is disabled by default and a floating MCLR pin can cause spurious resets. Always tie MCLR to VDD through a 10 kohm resistor, with a capacitor to ground only if the application requires RC-based reset timing. Also verify that the device configuration bits set the watchdog timer and code-protect correctly, since configuration words are NOT erased by a bulk Flash erase and must be reprogrammed explicitly.
