PIC24F04KA201-I/P - 16-Bit 32MHz 4KB MCU | Microchip
MPN: PIC24F04KA201-I/P ✓ Hoạt độngPIC24F04KA201-I/P Tóm tắt
A microcontroller is a programmable semiconductor that integrates a CPU, Flash program memory, RAM, and peripherals on one device. The PIC24F04KA201 belongs to the PIC24F family of 16-bit RISC microcontrollers and uses nanoWatt XLP technology to reduce current consumption during idle, sleep, and deep-sleep operation. Its deep-sleep features include DSBOR and DSWDT, while the RTCC supports low-power timekeeping applications.
Key device attributes include up to 16 MIPS performance, a 10-bit 500 kSPS ADC, CTMU touch and measurement capability, UART communication, and basic code-guard security. The 4 KB Flash capacity provides 1,375 words of program memory, while the 20-pin PDIP package supports conventional through-hole PCB assembly and prototyping.
The device combines a compact general-purpose platform with application-specific peripherals in a low-cost 16-bit architecture. Its 32 MHz performance ceiling and 16 MIPS throughput support control loops, communication tasks, data acquisition, and low-power sensor handling. The ADC and CTMU make it useful where analog measurement or capacitive-touch sensing is needed without adding separate interface ICs.
Typical applications include battery-powered monitors, environmental sensors, small industrial controls, building and access equipment, energy-harvesting nodes, touch interfaces, and low-cost embedded products. The deep-sleep modes are particularly valuable when average standby power dominates the operating budget.
Design with the manufacturer datasheet and family data sheet as the controlling references. Confirm the exact operating-voltage limits, pin functions, oscillator configurations, ADC limits, and absolute maximum ratings for the selected package. Place decoupling capacitors close to the supply pins and use a compatible clock and programming arrangement for the target board.

Ứng dụng tiêu biểu
PIC24F04KA201-I/P phù hợp cho 6 Áp dụngs: Battery-Powered Environmental Sensor, Capacitive-Touch User Interface, Low-Power Data Logger, Industrial Control Module, Energy-Harvesting Sensor Node, Small Building or Access Controller.
Battery-Powered Environmental Sensor
The PIC24F04KA201-I/P fits compact environmental monitors because its 16-bit PIC RISC core reaches up to 32 MHz and 16 MIPS while the device includes nanoWatt XLP operation, DSBOR, DSWDT, and RTCC. The 10-bit 500 kSPS ADC can acquire sensor voltages, while the 512-byte RAM and 4 KB Flash support short sampling and filtering cycles. Place the MCU between the sensor output and the system power switch, retain the RTC for time-stamped measurements, and use deep sleep between samples. The engineering trade-off is limited memory, so avoid buffering large datasets locally.
Được đề xuất
Capacitive-Touch User Interface
The PIC24F04KA201-I/P supports capacitive-touch and measurement functions through its integrated CTMU while providing up to 16 MIPS for debouncing, filtering, and interface updates. Its 4 KB Flash and 512-byte RAM are suitable for compact controls with a small number of electrodes and a serial command interface. Connect the CTMU-capable pins to the sensing network and use the UART for configuration or status reporting. Because the 20-pin PDIP footprint is through-hole, this variant is especially useful during prototyping or low-volume rugged control assemblies.
Được đề xuất
Low-Power Data Logger
The PIC24F04KA201-I/P is appropriate for a low-power data logger that periodically samples analog inputs and stores compact records. The 500 kSPS ADC provides useful acquisition headroom, while the 32 MHz core and 16 MIPS performance support calibration and signal processing between wake events. Use the RTCC to schedule measurements and use DSWDT or DSBOR behavior to protect low-power operation. Designers should account for the 512-byte RAM and 4 KB Flash limits, perhaps using an external serial memory if records must be retained between longer intervals.
Được đề xuất
Industrial Control Module
The PIC24F04KA201-I/P can serve as the local controller in a small industrial module that reads analog process signals, manages discrete inputs, and reports status through UART. Its 16-bit architecture and 16 MIPS maximum performance provide useful control headroom, and the industrial -I grade supports an industrial-oriented operating class. The 20-pin PDIP package is practical for serviceable or panel-board assemblies. Designers must verify voltage levels, I/O limits, ADC accuracy, and isolation requirements against the family data sheet; the MCU does not replace the protection, filtering, and isolation normally required in industrial interfaces.
Được đề xuất
Energy-Harvesting Sensor Node
The PIC24F04KA201-I/P suits energy-constrained nodes because nanoWatt XLP, deep-sleep support, DSBOR, and DSWDT are designed for low standby consumption. The MCU can wake periodically, use the 10-bit ADC to evaluate an energy-harvesting or sensing node, and transmit a result over UART. Keep the active duty cycle short so harvested energy can replenish the storage capacitor between operations. Actual suitability depends on the available energy source, wake latency, and leakage; calculate the average current from measured operating states rather than relying on the MCU's active current alone.
Được đề xuất
Small Building or Access Controller
The PIC24F04KA201-I/P can coordinate a compact access, alarm, or building-control node that accepts digital inputs, drives simple outputs, and reports state over UART. Its 4 KB Flash is suitable for a focused firmware image, and the RTCC supports time-based schedules or event logging. The 20-pin PDIP package simplifies hand assembly and rework compared with a fine-pitch surface-mount MCU. For deployment, validate the exact -I temperature range, supply tolerance, and I/O levels, and include appropriate isolation or protection if the controller connects to external field wiring.

Ghi chú thiết kế
Design the power budget around the actual operating mode rather than a single current value. The family provides nanoWatt XLP, DSBOR, and DSWDT for low-power behavior, but the final average current also depends on the ADC state, oscillator choice, peripherals, wake events, and the sensor load. Use the manufacturer sleep and active-current limits, then include margin for board leakage and external components. Do not claim a battery-life figure until the duty cycle and all always-on loads have been measured.
Follow the family data sheet's decoupling and layout guidance exactly, because the provided snippets do not include the pinout or capacitor values. Place each required supply capacitor close to its corresponding VDD and VSS connection, provide a low-impedance ground return, and keep analog sensor traces away from switching nodes. The 20-pin PDIP footprint offers generous through-hole routing, but every external signal still needs correct filtering and protection. Check package drawings before drilling or defining the PCB land pattern.
Do not treat the -I/SO and -I/MQ family orderings as physical drop-ins for the -I/P PDIP device, and do not assume that a cross-brand MCU is firmware-compatible. A substitute must be checked for package dimensions, pin numbers, I/O levels, ADC mapping, oscillator pins, reset behavior, and programming interface. The supplied web results do not establish five verified drop-in alternatives for this target; use the Microchip cross-reference search and compare against document 30009937C before approving any substitution.
Preserve the integrity of the ADC and CTMU measurements by separating sensitive analog inputs from fast-changing digital and clock paths. Use a quiet ground reference for analog input filtering, place input resistors or capacitors at the source where appropriate, and avoid routing measurement traces beneath high-current switching nodes. Because the 10-bit ADC is specified at 500 kSPS, acquisition and averaging time must match the signal bandwidth. Verify the exact ADC and CTMU channel assignments against the 20-pin PDIP pinout before final routing.
