PIC24F16KA102-E/SP - 32MHz 16-Bit XLP MCU | Microchip
MPN: PIC24F16KA102-E/SP ✓ Hoạt độngPIC24F16KA102-E/SP Tóm tắt
An ultra-low-power microcontroller is a control IC optimized to minimize energy consumption during both active operation and idle periods. The PIC24F16KA102 combines a 16-bit architecture with XLP low-power features, allowing embedded products to retain processing capability while reducing standby demand. In a power hierarchy, it belongs to the embedded microcontroller class, combines a CPU, memory, timers, communication peripherals, and power-management functions in one device, and serves as the central controller for compact battery-operated systems.
Key features include 16 KB of program Flash memory, 1.5 KB of RAM, 18 general-purpose I/O pins, a 32 MHz maximum speed, an internal oscillator, and 512 bytes of EEPROM. The -E/SP ordering option identifies the extended-temperature 28-pin SPDIP configuration. The MCU also supports nanoWatt XLP operating concepts designed to conserve energy in applications where the main challenge is maintaining useful responsiveness while the product spends substantial time in low-power states.
The device belongs to the PIC24F16KA102 family, which combines a 16-bit CPU with a broad peripheral set and enhanced computational performance. Its integrated real-time clock and calendar supports timekeeping-oriented designs, while DSBOR and DSWDT help manage brownout and watchdog behavior in low-power systems. The 18 available I/O pins provide connections for sensors, indicators, controls, communications, and external interfaces without requiring a separate processor for basic embedded control.
Typical applications include battery-powered sensors, compact industrial monitors, portable measurement instruments, low-power control modules, and embedded products that periodically wake to collect information and return to a low-energy state. The internal oscillator also reduces the number of external clock components required in cost-sensitive designs. For designs requiring more communication capability or precision analog measurement, the PIC24F16KA102 can serve as the low-power supervisory controller alongside dedicated interface and conversion components.
When designing around this MCU, verify the complete pin configuration, peripheral multiplexing, and timing requirements against the manufacturer’s family datasheet before assigning PCB functions. Pay particular attention to brownout, watchdog, and sleep-mode configuration during firmware development, because incorrect peripheral setup can prevent the expected low-power behavior even when the nominal clock and memory specifications are met.
This page combines manufacturer family information, exact-ordering data, application guidance, comparison criteria, and practical design notes to support component selection and PCB planning. It also highlights the limited availability of genuinely pin-compatible alternatives, avoiding the inclusion of parts with incompatible packages or materially different memory configurations.

Ứng dụng tiêu biểu
PIC24F16KA102-E/SP phù hợp cho 6 Áp dụngs: Battery-Powered Environmental Sensor, Portable Industrial Data Logger, Low-Power Remote Control, Smart Home Sensor Node, Compact Energy-Control Module, Timing and Control Instrument.
Battery-Powered Environmental Sensor
The PIC24F16KA102-E/SP fits battery-powered environmental monitoring because its XLP design supports low-power operating strategies, while its 16-bit architecture and 32 MHz speed can handle sampling, filtering, and control tasks between wake-ups. The 16 KB Flash stores firmware and the 1.5 KB RAM supports working data, leaving 512 bytes of EEPROM available for calibration or configuration retention. An internal oscillator can also reduce external clock-component requirements. In a final design, disable unused peripherals during sleep, review external pull networks for leakage, and verify the complete current profile with the sensor interface connected.
Được đề xuất
Portable Industrial Data Logger
A compact data logger can use the PIC24F16KA102-E/SP to supervise periodic measurements and store operating information without continuously powering every peripheral. Its 32 MHz processing rate provides headroom for sensor conditioning, timestamp handling, and communication framing, while 18 I/O pins support switches, status indicators, and digital sensors. The real-time clock and calendar is especially relevant when records must retain accurate timing across long idle periods. Firmware should use the DSWDT and DSBOR features deliberately, then validate wake behavior, data retention, and average current against the complete logger board.
Được đề xuất
Low-Power Remote Control
The PIC24F16KA102-E/SP is suitable for a handheld or remotely installed controller that wakes on a user action, interprets an input, updates an indicator, and returns to a low-energy state. Its 16-bit CPU and 32 MHz maximum speed provide responsive control for menu handling and communication routines, while XLP features support the contrast between brief active periods and extended standby periods. The 18 I/O pins can accommodate buttons, status LEDs, and an external communication device. Avoid latching relays or high-current outputs directly on MCU pins; use suitable driver circuitry and confirm standby current with all external loads attached.
Được đề xuất
Smart Home Sensor Node
A smart-home sensor node benefits from the PIC24F16KA102-E/SP when it must combine sensor conditioning, local logic, and periodic communications within one 28-pin SPDIP design. The 16 KB Flash capacity accommodates application firmware, 1.5 KB RAM supports protocol and measurement buffers, and 512 bytes of EEPROM can retain settings that should survive resets. Deep-sleep behavior allows the node to remain available without continuously operating its radio or sensor interface. The internal oscillator helps minimize component count, although radio transceivers usually need careful sequencing and decoupling, so their standby and active states must be coordinated in firmware.
Được đề xuất
Compact Energy-Control Module
The PIC24F16KA102-E/SP can act as the supervisory controller in a compact energy or equipment-control module, handling operating modes, timing, indicators, and fault supervision. Its 32 MHz speed supports deterministic control tasks, and the 18 I/O pins provide sufficient connections for digital inputs and outputs without requiring a large package. DSBOR and DSWDT support robust behavior when the module must recover from undervoltage or stalled firmware. High-voltage or high-current switching functions should remain outside the MCU domain, with isolation, drive circuitry, and protective components selected for the actual load and safety requirements.
Được đề xuất
Timing and Control Instrument
The PIC24F16KA102-E/SP can support a compact timing, sequence-control, or calibration instrument where the real-time clock and calendar, 32-bit-capable performance, and low-power modes are useful. The 16 KB program Flash is appropriate for a focused embedded control application, while the 512-byte EEPROM can hold basic calibration records or configuration identifiers. Its 18 I/O pins allow direct connection to displays, switches, indicators, and measurement interfaces. When an analog front end is required, verify the MCU’s available ADC resources and pin multiplexing; add a dedicated converter when the required accuracy, rate, or channel count exceeds the integrated peripheral set.

Ghi chú thiết kế
Configure the application around the MCU’s active and sleep states rather than treating 32 MHz as a continuous operating requirement. Disable unused peripherals, remove unnecessary pull-ups, and use the XLP, DSBOR, DSWDT, and real-time clock features only after reviewing their configuration requirements in the Microchip family datasheet. Measure current with the complete sensor, communications, and indicator circuitry attached because board-level leakage can dominate a deeply sleeping design.
Use the 28-pin SPDIP footprint associated with the -SP ordering suffix and follow the package drawing and pin-description table in the manufacturer datasheet. Preserve access around the device for programming and prototype rework, and place decoupling capacitors close to the appropriate supply pins. Because this MCU multiplexes several peripherals onto its 18 I/O pins, finalize signal assignments before routing to prevent avoidable footprint changes.
Do not substitute PIC24F16KA102-E/SO or another package suffix for the target -SP device on an existing board. A cross-temperature-grade substitution such as PIC24F16KA102-I/SP also requires confirmation that its operating-temperature range covers the complete product environment. Treat firmware startup, watchdog, brownout, and peripheral-sharing behavior as qualification items even when the headline memory and clock specifications match.
Keep oscillator, programming, and sensitive communication routes away from long switching-node traces where practical. Follow the manufacturer layout guidance for decoupling and external support components, and provide adequate ground-return paths for attached sensors or communications circuits. If an external oscillator is added in a future revision, reserve its footprint and routing only after checking the family oscillator and clock-selection requirements in the datasheet.
