PIC24F16KA102-E/SO - 16KB Flash XLP MCU SOIC-28 | Microchip

The Microchip PIC24F16KA102-E/SO is a 16-bit microcontroller built on the PIC24F family with nanoWatt XLP eXtreme Low Power technology, offering 16 KB of Flash program memory, 1.5 KB of RAM, and 512 bytes of EEPROM in a 28-pin SOIC package. It executes instructions at up to 16 MIPS from a 32 MHz internal oscillator, making it suitable for real-time control in power-constrained designs. A 16-bit microcontroller (MCU) is an embedded processor with a 16-bit data path, registers, and ALU, positioned between 8-bit microcontrollers (lower cost, lower performance) and 32-bit microcontrollers (higher performance, higher cost). PIC24F devices sit in the broader taxonomy as: PIC24F 16-bit Flash MCU -> 16-bit microcontroller -> embedded processor -> integrated circuit. They are commonly used where 8-bit MCUs lack DSP-style math performance but 32-bit parts are unnecessary for cost or power reasons. Key features include deep sleep mode with DSBOR (deep-sleep brown-out reset), DSWDT (deep-sleep watchdog timer), and RTCC (real-time clock calendar) retention, plus an integrated 10-bit ADC with up to 9 channels, two comparators, multiple 16-bit timers, and two watchdog timers. The -E temperature grade supports -40C to +125C operation, and the XLP technology achieves sub-uA sleep currents that suit battery-powered and energy-harvesting products. The architecture uses a modified Harvard core with a 24-bit instruction word, allowing single-cycle 16x16 MAC for small-signal processing. The internal 32 MHz oscillator and PLL deliver up to 16 MIPS throughput, while peripheral pin select and flexible I/O mapping simplify PCB routing in space-constrained enclosures. Typical applications include IoT sensor nodes, wearable health monitors, remote controls, low-power wireless modules, battery-backed instrumentation, and consumer appliances. The combination of nanoWatt XLP sleep current and fast wake-up time from sleep makes it ideal for products that spend most of their life in deep sleep and wake periodically for measurement and transmission. When designing with this device, prioritize deep-sleep current budget and wake-up source selection early in the design; an incorrectly configured RTCC or DSWDT can keep the device out of its lowest-power state. Plan unused pins as digital outputs tied low rather than floating inputs to avoid parasitic current paths.

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.

It runs at up to 32 MHz delivering 16 MIPS and operates from 1.8V to 3.6V, making it suitable for both 3.3V and 5V-tolerant-system designs when paired with appropriate interface ICs. A 16-bit microcontroller is a programmable computing device built around a 16-bit data path, register file, and ALU, sitting hierarchically between 8-bit MCUs and 32-bit Cortex-M devices. The PIC24F family uses Microchip's modified Harvard architecture with a 16-bit instruction word and 24-bit instruction fetch, giving it a deterministic instruction set and predictable interrupt latency that distinguishes it from von-Neumann ARM parts. The KA-series sub-family adds the XLP power-management peripheral set, which is why designers choose it for battery-powered applications. Key features of the PIC24F16KA301T-I/SO include Deep Sleep current as low as 20 nA with RTCC, DSBOR, and DSWDT active, plus multiple low-power sleep modes down to a few hundred nanoamps in Sleep mode.

It integrates 16KB of Flash program memory organized as 5.5K x 24 words, 2KB of SRAM data memory, and 512 bytes of Data EEPROM, executing up to 16 MIPS at 32 MHz from a 1.8V to 3.6V supply. The 'T' suffix denotes Tape & Reel packaging while 'I' denotes the industrial -40C to +85C temperature range. A 16-bit microcontroller (MCU) is a microprocessor-on-a-chip that combines a CPU core, non-volatile program memory, volatile data memory, and peripheral subsystems (ADC, timers, communication interfaces) on a single die. Within the embedded taxonomy, the PIC24F sits between 8-bit PIC MCUs and 32-bit ARM Cortex-M devices, offering a C-friendly modified Harvard architecture with deterministic interrupt response - a class commonly chosen when 8-bit performance is insufficient but 32-bit cost or power is overkill. Key features of the PIC24F16KA301T-I/SS include XLP technology with Deep Sleep current under 100 nA, an integrated 12-bit ADC with up to 12 channels, dual I2C / SPI / UART communication interfaces, a Charge Time Measurement Unit (CTMU) for capacitive touch and accurate time measurement, and three PWM channels with seven timers. The 17 I/O pins support peripheral pin select (PPS) for flexible signal routing. The device uses a modified Harvard RISC architecture with a 16-bit instruction word and a hardware multiplier that performs 17-bit x 17-bit single-cycle operations. On-chip peripherals include DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer), and a Real-Time Clock Calendar (RTCC) that continue to operate in Deep Sleep mode - unique among mid-range 16-bit MCUs and enabling decade-long battery life on a single coin cell. Typical applications include battery-powered sensor nodes, wearable health monitors, remote controls, low-energy wireless sensor hubs, e-metering, and IoT edge devices. The CTMU peripheral enables capacitive touch buttons and sliders without an external controller, while the RTCC eliminates external RTC chips in time-stamped data loggers. When designing with this part, choose Deep Sleep mode for quiescent periods where average current dominates lifetime, and use the DSWDT to wake the device periodically for sensor polling.

Key differentiating features of the PIC24F16KA302 include the XLP Deep Sleep current (sub-uA range), the integrated CTMU for capacitive touch and precision time measurement, the RTCC with calendar mode, and a DSBOR/DSWDT (Deep Sleep Brown-Out Reset / Deep Sleep Watchdog Timer) that maintains supervisory functions while the core is asleep. These features let the device wake only on a meaningful event, dramatically extending battery life in sensor and metering products. The architecture is a modified Harvard 16-bit RISC core with a hardware multiplier for fast DSP-style operations, plus a rich peripheral set including multiple timers, UART, SPI, I2C, and 12-bit ADC with up to 13 input channels (package-dependent). The device operates from 1.8 V to 3.6 V across the industrial temperature range of -40C to +125C, and supports in-circuit serial programming (ICSP) and self-programmability. Typical applications span battery-powered sensor nodes, IoT edge devices, wearable health monitors, remote controls, smart metering, capacitive touch user interfaces, and industrial control where Deep Sleep consumption is the dominant lifetime metric. The -E temperature grade extends operation to +125C, suitable for harsh industrial environments. When designing with this part, choose the internal 8 MHz or 32 kHz oscillators carefully: switching to the low-power oscillator and disabling unused peripherals in Deep Sleep typically cuts quiescent current by orders of magnitude compared to running the full 32 MHz MIPS core. The CTMU requires careful PCB layout for capacitive touch: keep the sense traces short, guarded by a ground ring, and avoid running them near high-frequency signals.

A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash/ROM), data memory (RAM), and integrated peripherals such as timers, ADC/DAC, communication interfaces, and I/O ports. The PIC24F16KA304 belongs to the 16-bit PIC24F family, which sits in Microchip's hierarchy: 16-bit MCU -> PIC24F -> PIC24F XLP low-power series -> power-constrained and battery-powered applications. Compared with 8-bit PIC16/PIC18 parts, the 16-bit core enables larger address spaces, wider data paths, and richer DSP-style arithmetic for signal processing. Key features include a 12-bit A/D converter with up to 30 channels depending on package, multiple communication peripherals (UART, SPI, I2C), 5 timers, a Real-Time Clock and Calendar (RTCC) that operates in Deep Sleep, plus dedicated Deep Sleep Brown-Out Reset (DSBOR) and Deep Sleep Watchdog Timer (DSWDT). XLP technology enables typical Deep Sleep currents measured in nanoamperes, making the device well suited to battery-powered designs. The CTMU (Charge Time Measurement Unit) supports capacitive touch sensing and precise time-of-flight measurements. The architecture uses a modified Harvard design with separate program and data buses, a 24-bit instruction word for compact code density, and a deterministic interrupt model. Up to 32 MHz operation across an industrial -40C to +85C range provides ample headroom for closed-loop control, sensor fusion, and USB-less communication stacks. Typical applications include battery-powered sensor nodes, IoT edge devices, portable medical instrumentation, consumer wearables, and industrial data loggers. The wide operating range also suits automotive accessory and ruggedized telemetry systems. When designing with this part, pair a low-Iq LDO with the MCU, route the 32.768 kHz crystal traces short and guarded, and use the CTMU only after calibrating against an internal reference to achieve reliable touch sensing.

The part suffix "/PT" denotes the 44-pin TQFP package while the trailing "T" in the part number indicates tape-and-reel packaging. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich mix of peripherals such as ADCs, timers, communication interfaces, and I/O ports onto a single silicon die. Within the broader hierarchy, this device sits in the microcontrollers branch of integrated circuits, alongside the categories of digital signal controllers (DSCs) and microprocessors (MPUs). PIC24F devices specifically target applications where deterministic real-time response and ultra-low power consumption are required, slotting between 8-bit PIC16/PIC18 MCUs and higher-performance dsPIC33/PIC32 parts. Key features of the PIC24F16KA304 family include the eXtreme Low Power (XLP) technology, with typical Deep Sleep currents below the microamp range, and on-chip peripherals such as the RTCC, DS-WDT, and DS-BOR that continue running while the CPU is halted.

Multiple serial interfaces (UART, SPI, I2C) and a configurable 16-bit timer/capture/compare/PWM block support motor control, sensor fusion, and human-interface designs. The architecture uses a modified Harvard layout with separate program Flash and data RAM buses, allowing simultaneous instruction fetch and data access, plus a 16-element working register array that simplifies C compiler code generation. The XLP technology targets battery-powered designs where average current consumption dominates battery-life calculations, making the part well-suited for products that spend most of their operational life in sleep states. JTAG and ICSP debug interfaces are supported through dedicated pins, enabling in-circuit debugging without consuming additional package pins. Typical applications include battery-powered IoT sensor nodes, wearable health and fitness devices, remote controls, electronic shelf labels, smart thermostats, low-power wireless sensor hubs, and industrial metering where long battery life and moderate processing performance are both required. The 44-pin TQFP package provides ample I/O for mixed-signal designs while maintaining a small 10x10 mm footprint. When designing with this MCU, ensure the VDDCORE pin is bypassed with the recommended LC/RC filter and that VDD is decoupled with a 100 nF ceramic capacitor placed within 5 mm of the package. For lowest deep-sleep current, leave unused I/O pins configured as outputs driving low and disable unused peripherals via the PMD (Peripheral Module Disable) registers before entering sleep.
