PIC24F16KA102-I/SP - 32MHz 16KB XLP MCU | Microchip
Référence : PIC24F16KA102-I/SP ✓ ActifPIC24F16KA102-I/SP Présentation
A microcontroller is an embedded control IC that integrates a processor core, program memory, data memory, peripherals, and I/O into one device. The PIC24F16KA102 belongs to the PIC24F family and is positioned for industrial control, IoT equipment, embedded automation, motor control, metering, and other low-power applications. Its 16-bit PIC RISC architecture provides a practical balance of processing capability, peripheral integration, and energy efficiency.
The device provides 16 KB, or 5.5K x 24 words, of Flash memory and 1.5K x 8 bits of SRAM. The supplied distributor data also identifies 512 bytes of EEPROM, an internal oscillator, and 18 I/O in the 28-pin device. Operation is associated with 2.5 V and 3.3 V supply options. XLP technology and dedicated low-power features help reduce active and dormant current consumption when system energy budgets are restrictive.
The PIC24F16KA102 family combines a 16-bit architecture with a broad peripheral feature set and enhanced computational performance. Its integration reduces the need for separate memory, monitoring, and timing components in compact embedded systems. The deep-sleep mode, DSBOR, DSWDT, and RTCC functions give firmware designers dedicated mechanisms for managing power state, brownout behavior, watchdog supervision, and real-time timing requirements.
Typical uses include industrial sensor nodes, connected metering equipment, compact control panels, battery-operated monitors, and low-power embedded automation. The internal oscillator may simplify board design when an external crystal is unnecessary, while the 18 available I/O support digital interfaces and discrete control functions. Actual peripheral availability and pin multiplexing remain application-specific, so the manufacturer pinout and datasheet should be checked before assigning external functions.
Designers should compare the 28-pin SPDIP footprint against the final assembly method, then validate startup behavior, watchdog settings, brownout configuration, and sleep-mode current on the assembled board. The PIC24F16KA102-I/SP is supplied in a tube, which suits prototyping and manual or fixture-assisted assembly. For production quantities, packaging logistics and sourcing should be confirmed with an authorized distributor.

Applications typiques
PIC24F16KA102-I/SP convient pour 6 applications: Battery-Powered Sensor Nodes, Industrial Metering Equipment, Embedded Automation Control, Low-Power IoT Control Boards, Motor and Actuator Control, Compact Embedded Control Panels.
Battery-Powered Sensor Nodes
The PIC24F16KA102-I/SP fits battery-powered sensor nodes that spend much of their operating time waiting for measurements. Its XLP eXtreme Low Power architecture, deep-sleep mode, DSBOR, DSWDT, and RTCC features provide dedicated mechanisms for controlling reset behavior, watchdog supervision, timing, and low-duty-cycle operation. At 32 MHz, the 16-bit PIC RISC core also has enough performance to acquire data, apply local filtering, and format results without waking a more capable host. The 512-byte EEPROM and 16 KB of Flash support configuration and firmware storage, although actual retention and endurance requirements must be checked in the datasheet. A sleep-current measurement on the populated board is essential because external sensors, pull resistors, and regulator leakage can dominate the MCU contribution.
Recommandé
Industrial Metering Equipment
PIC24F16KA102-I/SP is suitable for metering equipment that combines measurement timing, local control, and low-power operation. The 32 MHz 16-bit processor can supervise counting, signal conditioning, status logic, and communications while the 1.5K x 8-bit SRAM supports working data and 512 bytes of EEPROM can assist with nonvolatile configuration storage. Eighteen I/O provide external connections for sensors, indicators, and control signals, subject to the device's fixed pin assignments. RTCC supports time-related system functions, while DSWDT and DSBOR contribute to recovery from abnormal operating conditions. For battery or energy-harvested meters, firmware should use deep-sleep mode during long measurement intervals and keep unused peripherals disabled. Validate accuracy, calibration retention, and restart behavior at the system level.
Recommandé
Embedded Automation Control
The PIC24F16KA102-I/SP supports compact embedded automation controllers that need deterministic control logic without a high-power application processor. Its 16-bit PIC RISC core runs at up to 32 MHz and can execute state-machine logic, input filtering, actuator sequencing, diagnostics, and communication tasks. The 28-pin SPDIP package provides 18 I/O for discrete sensors, relays, status indicators, and external interfaces, with final assignments governed by the datasheet pinout. XLP operation is valuable in machinery that spends long intervals between operator or production events: the MCU can enter deep sleep between jobs and use DSWDT to recover from firmware faults. The 16 KB Flash capacity is suitable for compact control firmware, but applications requiring extensive protocol stacks should verify code-space requirements and add external memory where necessary.
Recommandé
Low-Power IoT Control Boards
PIC24F16KA102-I/SP can serve as the always-on control MCU in a low-power IoT node, especially where local sensing and deterministic state management are more important than high graphics or network-processing performance. The 32 MHz core handles peripheral control, packet preparation, debouncing, and low-level protocol tasks, while deep sleep can reduce consumption during idle intervals. RTCC provides timing resources, and DSBOR plus DSWDT support robust behavior on disturbed or unreliable supply rails. The 18 I/O allow connections to environmental sensors, status indicators, and discrete interfaces, while 16 KB of Flash provides room for a focused application. Wireless-module integration still requires careful partitioning of sleep timers and I/O wake behavior. Validate radio-module supply current and ensure the MCU retains state across the longest intended sleep interval.
Recommandé
Motor and Actuator Control
The PIC24F16KA102-I/SP can serve as a supervisory controller in motor or actuator systems where compact logic, timing, and fault handling are required. Its 32 MHz 16-bit architecture can execute motion-state tables, calculate command timing, process limit inputs, and coordinate outputs, while the 18 I/O provide connections for sensors, switches, status signals, and driver-control lines. Deep-sleep operation may reduce consumption when the actuator is stationary, and DSWDT can restart a stalled control loop after a fault. Actual drive-stage timing must be checked against the device's peripheral limits and pin assignments from the manufacturer datasheet. The MCU is best suited to supervisory rather than high-performance motion computation, and any protection scheme should operate directly in hardware where possible so that a firmware fault cannot defeat the safety function.
Recommandé
Compact Embedded Control Panels
PIC24F16KA102-I/SP is useful in compact control panels that scan inputs, drive indicators, enforce timing, and manage low-power standby behavior. Its 16-bit core and 32 MHz clock provide sufficient performance for menu logic, debouncing, event logging, and basic supervisory control, while 1.5K x 8 bits of SRAM supports temporary working state. The 28-pin SPDIP package offers 18 I/O for buttons, lamps, and interface signals, making it convenient for prototypes and through-hole industrial boards. XLP features can reduce standby consumption, and RTCC can support scheduled events or elapsed-time functions. The 16 KB Flash limit should be checked against the panel application and any logging requirements. Display and communication interfaces must also be mapped according to the fixed pinout rather than assumed from function names.

Notes de conception
Use deep-sleep mode as part of the system power architecture rather than treating it only as a firmware optimization. Disable unused peripherals, remove unnecessary external pull resistors, and measure sleep current with the complete sensor and regulator load attached. The MCU's XLP behavior is useful for battery-powered designs, but board-level leakage can dominate the result. Compare wake time and current over a complete operating cycle rather than quoting only the MCU's nominal processing speed.
Do not substitute the /SS, /ML, /SO, or other package variants for /SP on an existing board. The verified drop-in alternative is PIC24F16KA102-E/SP because it retains the 28-pin SPDIP footprint. Confirm the manufacturer pinout, 18-I/O assignment, reset behavior, and grade-specific temperature requirements before fitting an alternative or changing the footprint.
Keep the 28-pin SPDIP footprint and its drilling pattern compatible with the chosen alternative. Place the decoupling network at the device supply pins and route sensitive inputs away from switching nodes and high-current return paths. Because the supplied evidence does not provide the complete pin names, verify every net against the official family datasheet before fabrication and confirm whether unused pins require specific termination.
Plan DSWDT, DSBOR, and deep-sleep behavior as part of firmware validation. Test brownout transitions across the intended supply range, force a watchdog reset during representative operating states, and verify that recovery does not cause unsafe outputs. The 32 MHz clock gives ample control-loop headroom, but timing accuracy still depends on the selected clock source and configuration recorded in the datasheet.
Informations de conformité
The supplied records do not explicitly extract RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for this ordering code. An Arrow listing includes an AEC-Q100 descriptor, but the snippet does not provide a qualification statement tied clearly to the PIC24F16KA102-I/SP grade; it is therefore not treated as verified qualification.
