PIC24F16KA101T-I/SS Présentation
What is a PIC24F XLP microcontroller? The PIC24F is a 16-bit modified-Harvard RISC family from Microchip Technology. It is a member of the broader microcontroller (MCU) semiconductor category, and within that hierarchy sits the low-power (XLP) subfamily with nanoWatt technology and integrated peripherals such as A/D, comparators, RTCC and deep-sleep mode. The 32 MHz core delivers 16 MIPS throughput, with a 16-bit instruction word and most instructions executing in a single cycle, giving the PIC24F roughly 3-5x the compute density of 8-bit PIC MCUs at the same clock.
Key features of the PIC24F16KA101T-I/SS include 16KB (5.5K x 24) self-programmable Flash, 1.5KB SRAM, 512B EEPROM, 18 general-purpose I/O pins, and an internal oscillator. The XLP architecture claims industry-leading low-power performance with deep-sleep current in the nanoamp range and RTCC operation from a 32 kHz crystal, enabling multi-year battery life in duty-cycled sensing nodes.
The device integrates configurable peripherals such as 10-bit A/D, analog comparators with selectable references, UART/SPI/I2C™/IrDA® connectivity, multiple timers and a Real-Time Clock Calendar (RTCC). Programmable brown-out reset (BOR), watchdog timer (WDT) and the deep-sleep DSBOR/DSWDT extend supervisory coverage to the lowest power states.
Typical applications include battery-powered IoT sensor nodes, portable medical/health monitors, e-metering peripherals, remote controls, wearable fitness bands, and consumer products requiring long battery life with sufficient compute for small protocol stacks or sensor fusion. Designers also deploy this MCU in industrial telemetry and HVAC controllers where eXtreme Low Power with deterministic 16-bit performance is required.
Design consideration: because the SSOP package has moderate thermal dissipation, derate I/O source/sink current per pin (typically ≤25 mA) and observe total package dissipation when multiple I/Os switch simultaneously. Use the internal PLL only when VIN is stable, and select the low-power secondary oscillator (SOSC) for RTCC-based sleep cycles to maximize battery life. This page consolidates XAIPART distributor pricing, drop-in SSOP-20 alternatives, and practical design notes not found in the standalone Microchip datasheet.

Applications typiques
PIC24F16KA101T-I/SS convient pour 6 applications: Battery-Powered IoT Sensor Nodes, Portable Medical and Health Monitors, Remote Controls and Consumer HMI, E-Metering and Utility Telemetry, Wearable Fitness Bands, Industrial Sensor and HVAC Controllers.
Battery-Powered IoT Sensor Nodes
The PIC24F16KA101T-I/SS fits battery-powered IoT sensor nodes because of its nanoWatt XLP architecture and 1.8V to 3.6V supply range that allows direct operation from a single CR2032, two-AAA, or Li-primary cell. According to the Microchip product page, its deep-sleep mode with DSBOR/DSWDT retention drops quiescent current into the nanoamp range, while the integrated 32.768 kHz SOSC keeps the RTCC alive for duty-cycled wakeups that wake the CPU only to take a measurement. The 16 MIPS 16-bit core at 32 MHz is enough compute to run a small protocol stack (BLE controller, sub-GHz radio command interpreter, or LoRaWAN MAC state machine). Placed as the host MCU between the sensor and the radio, the part is pin-compatible with the lower-density PIC24F08KA101-I/SS (8KB Flash) for cost-down revisions.
Recommandé
Portable Medical and Health Monitors
The PIC24F16KA101T-I/SS suits portable medical and health monitors where extended battery life and deterministic 16-bit ADC performance are required. Per the Microchip product page, its 10-bit SAR A/D and analog comparators handle pulse-oximetry thermistor bridges and heart-rate sensor signal conditioning without an external op-amp. The 1.8V minimum supply lets the device run from two alkaline or one Li-primary coin cell, and the deep-sleep current in the nanoamp range enables multi-month runtimes on wearable patches. The 16 MIPS core runs simple DSP-style heart-rate-variability averaging algorithms and drives an SPI display or BLE link. Designers must validate IEC 60601-1 EMI margins, since the XLP low-power modes ease radiated emissions budgets.
Recommandé
Remote Controls and Consumer HMI
The PIC24F16KA101T-I/SS is well-matched to remote controls and consumer HMI products that need to run for years on a coin cell. The Microchip datasheet shows that the deep-sleep DSBOR/DSWDT with RTCC retention keeps battery drain low while a polled input or capacitive touch wake-up brings the 32 MHz core back to life in microseconds. Its 18 general-purpose I/O pins drive LED indicators, IR emitter LEDs, and matrix keypads, while the UART/SPI peripherals interface with RF companion chips or BLE modules. The 20-SSOP package suits slim, hand-held form factors. Compared to 8-bit PIC16 alternatives, the 16 MIPS compute headroom accelerates button-debounce and gesture handling without raising active power.
Recommandé
E-Metering and Utility Telemetry
The PIC24F16KA101T-I/SS is a strong fit for electronic metering and utility telemetry nodes where long-life battery operation is mandated. The Microchip product page highlights the deep-sleep DSBOR and the ability to retain RAM through brown-out events, which is critical for firmware state preservation during battery replacement. The 16 KB Flash holds metering calibration tables and small protocol stacks, while the 1.5 KB RAM buffers measurement frames before RF transmission. The 10-bit ADC samples current shunts or temperature sensors, and the RTCC drives time-stamping without external RTC chips. The 20-SSOP package integrates easily on tight metering PCBs, and the 1.8V minimum supply accepts 3.6V lithium packs directly.
Recommandé
Wearable Fitness Bands
The PIC24F16KA101T-I/SS supports wearable fitness bands where every microamp of sleep current extends the recharge interval. According to the Microchip datasheet, the XLP family with deep-sleep DSBOR/DSWDT and RTCC achieves nanoamp-level sleep with full register/RAM retention, allowing the MCU to wake only for accelerometer interrupts or scheduled steps-counting tasks. The 16-bit instruction set accelerates pedometer and sleep-stage classification algorithms versus 8-bit MCUs. The 32 MHz core drives an SPI OLED or BLE module and the integrated 10-bit ADC reads Li-ion battery voltage and thermistor skin temperature. Designers using the SSOP-20 package can place the IC on a flex PCB alongside a coin-cell battery.
Recommandé
Industrial Sensor and HVAC Controllers
The PIC24F16KA101T-I/SS fits industrial sensor and HVAC controller modules that must operate reliably from battery or wide-input supplies. The 1.8V to 3.6V supply range covers 3.3V regulated rails and two-AA battery packs, and the 18 I/O pins interface analog sensors, dry-contact inputs, and SSR-driver outputs. Per the Microchip product page, the deep-sleep DSBOR/DSWDT with RTCC keeps time-stamping accurate across power brown-outs, while the 10-bit ADC reads 4-20 mA loop signals through a burden resistor. The 16 MIPS core runs PID control loops and Modbus-over-UART framing, with the I2C bus connecting to a digital temperature/humidity sensor. The SSOP-20 industrial-grade footprint suits DIN-rail or wall-mount enclosures.

Principaux différenciateurs
- Industry-leading XLP deep-sleep current with RTCC retention (vs PIC24F08KA102T-I/SS)
- Extended-temperature grade option in identical footprint (vs PIC24F16KA101-E/SS)
- Footprint-flexible family members for PCB redesigns (vs PIC24F16KA101T-I/SO)
Notes de conception
Use the Low-Power Secondary Oscillator (SOSC) with a 32.768 kHz crystal during deep-sleep periods so the RTCC can keep time while the main FRC is off; this drops quiescent current into the nanoamp range per the Microchip XLP datasheet. Always populate a low-ESR 10uF ceramic plus 0.1uF decoupling pair within 5 mm of the VDD/VSS pins to suppress switching transients that could falsely trigger the BOR. Place a 1uF to 4.7uF capacitor on the VCAP pin (pin 19) to filter the internal 1.8V regulator, otherwise core logic may glitch under load steps.
Estimated: SSOP-20 has a theta_JA near 95 C/W on a 2-layer 1-oz JEDEC test board. At full CPU + I/O load with all 18 I/O toggling, total power dissipation typically stays well below 50 mW, so junction rise is ~5C above ambient - thermal management is rarely a concern for this part. However, when used in enclosed industrial enclosures at +85C ambient, designers should still derate I/O source current per pin to 12 mA to keep the package below 100C junction. Extended-temperature (-E) parts share identical silicon but are qualified to +125C.
Keep the 20-SSOP land pattern on 0.65 mm pitch per the Microchip package dimension drawing; SSOP and SOIC share pin count but not footprint. Route the ICSP™ pins PGED1 (RB0) and PGEC1 (RB1) to a 2x3 0.1-inch header so the MPLAB ICD 3 / PICkit 4 can be connected without rework. For noise-sensitive analog inputs, dedicate separate analog and digital VDD traces joined at a single point near the IC; the 10-bit ADC accuracy degrades if high-current digital traces run parallel to analog traces for more than 10 mm.
Do not enable the 4x PLL when VDD is below 2.0V or the part may fail to lock at cold temperatures; this is a common field issue documented in the PIC24F KA1 errata. Make sure unused I/O pins are configured as outputs driving low or as inputs with the internal weak pull-up enabled, to avoid floating-pin current leakage that can ruin battery-life budgets. When migrating between SSOP and SOIC or QFN packages, verify pin 1 orientation and the VCAP pin assignment, since SSOP pin 19 (VCAP) corresponds to a different physical pin on the QFN variant.
