PIC24F08KA101T-I/MQ - 16-Bit 32MHz XLP Microcontroller | Microchip
MPN： PIC24F08KA101T-I/MQ ✓ 啟用中PIC24F08KA101T-I/MQ 概覽
A microcontroller is the programmable control center of an embedded system, combining a processor core, nonvolatile program memory, working RAM, and peripherals such as timers, comparators, communication interfaces, and I/O ports on one integrated circuit. The PIC24F family uses a 16-bit architecture and delivers up to 16 MIPS, providing more computational headroom than many 8-bit controllers while retaining a compact, economical footprint.
XLP, or eXtreme Low Power, is Microchip's low-power design approach for battery-operated equipment. In the PIC24F08KA101, this approach includes peripherals that can continue operating in Deep Sleep mode, including DSBOR, DSWDT, and the RTCC. These features allow a product to maintain selected timekeeping, watchdog, or brown-out functions while reducing activity in the main CPU, flash, SRAM, and peripherals.
The PIC24F08KA101T-I/MQ provides 17 I/O ports, 8 KB of Flash organized as 2.75K x 24 words, and 1 KB of RAM according to the manufacturer listing. It also includes dual comparators, dual watchdog timers, dual PWM channels, and five general-purpose timers. The 20-VQFN package measures 5 x 5 mm, making the device suitable for densely populated control boards, portable instruments, sensor-hub products, and compact industrial modules.
Typical applications include low-power sensor nodes, building controls, battery-operated instruments, temperature-monitoring systems, motor-control subcircuits, and compact consumer products. The 32 MHz processing capability supports responsive control loops, while the 16-bit architecture simplifies handling of wider arithmetic values than an 8-bit MCU.
The primary design consideration is the 3.0 V to 3.6 V operating range. External circuitry must remain compatible with this supply window, and decoupling should follow the layout guidance in the manufacturer datasheet. For designs requiring an alternate package, verify the 20-pin VQFN footprint and exposed-pad requirements before committing the PCB layout.

典型應用
PIC24F08KA101T-I/MQ 適用於 6 應用s: Battery-Powered Sensor Nodes, Building and Environmental Controls, Battery Instruments and Portable Monitors, Temperature and Process Monitoring, Compact Motor and Lighting Control, Data Acquisition and Remote Sensor Hubs.
Battery-Powered Sensor Nodes
The PIC24F08KA101T-I/MQ fits distributed sensing nodes that must conserve energy between measurements. Its 16-bit core operates at up to 32 MHz, while nanoWart XLP technology supports Deep Sleep operation with DSBOR, DSWDT, and RTCC continuing to function. A firmware routine can therefore wake the device, sample a connected sensor through its 17 available I/O ports, transmit the result, and return to sleep. The 20-VQFN (5 x 5 mm) package also leaves room for a battery and radio in compact assemblies.
推薦
Building and Environmental Controls
The PIC24F08KA101T-I/MQ can serve as the local controller in a room thermostat, air-quality monitor, or small environmental-control panel. Seventeen I/O ports support digital inputs, indicator outputs, and communication lines, while two comparators can evaluate sensor thresholds without continuous CPU polling. Its 32 MHz 16-bit architecture provides responsive timing for display updates and control loops, and Deep Sleep reduces consumption during long idle periods. The small 5 x 5 mm VQFN package supports space-constrained wall controllers.
推薦
Battery Instruments and Portable Monitors
The PIC24F08KA101T-I/MQ is suitable for handheld meters, portable test equipment, and compact monitors where display, keypad, and measurement functions must coexist with limited energy. The 16-bit architecture handles values wider than those of an 8-bit controller, and up to 16 MIPS throughput allows responsive keypad and display servicing. Five general-purpose timers and two PWM channels support timing, backlight control, or simple stimulus generation, while XLP sleep modes reduce consumption between user interactions.
推薦
Temperature and Process Monitoring
The PIC24F08KA101T-I/MQ can implement local thermal or process supervision where two analog thresholds, periodic logging, and remote status reporting are required. Its dual comparators provide hardware threshold events that can interrupt the CPU, reducing polling overhead. The 8 KB Flash accommodates compact control and communication firmware, while the 1 KB RAM is suitable for short data buffers and stack-intensive routines. With two watchdog timers and Deep Sleep retention features, the controller can also monitor a slow-changing process while remaining mostly dormant.
推薦
Compact Motor and Lighting Control
The PIC24F08KA101T-I/MQ supports small motor-control, fan-control, or LED-lighting subcircuits where a compact controller and deterministic timing are required. Its two PWM channels can generate modulated drive signals, five general-purpose timers support input capture or elapsed-time measurement, and two comparators can detect current, position, or sensor thresholds. The 20-VQFN footprint permits placement close to power stages, although isolation, current sensing, and thermal management must be handled by the surrounding circuitry.
推薦
Data Acquisition and Remote Sensor Hubs
The PIC24F08KA101T-I/MQ can act as the acquisition controller in a small sensor hub that collects digital measurements, timestamps events, and forwards summarized data. Seventeen I/O ports leave sufficient external connections for sensors and a serial interface, while the 32 MHz clock rate provides headroom for protocol servicing and background timing. Deep Sleep can reduce activity when no new samples are expected, and the 5 x 5 mm VQFN package fits densely populated remote-node boards. Final communication peripheral selection should be confirmed from the device pin table.

主要差異化特點
- 32 MHz 16-bit processing in a compact 5 x 5 mm package (對比PIC24F08KA101-I/MQ)
- XLP sleep architecture retains selected supervisory functions (對比PIC24F08KA101T-E/MQ)

設計說明
The PIC24F08KA101T-I/MQ operates from 3.0 V to 3.6 V, so select a regulator whose tolerance and transient response keep the MCU rail inside that window at the highest operating frequency. For battery-powered designs, account for regulator quiescent current, sensor leakage, and radio sleep current because the MCU's XLP behavior cannot overcome excessive load current elsewhere in the system. Use the power-consumption and brown-out guidance in the manufacturer datasheet when configuring Deep Sleep and peripheral retention.
Route the 20-VQFN (MQ) footprint strictly from the manufacturer land pattern, including the exposed pad and its thermal-via arrangement. Place input decoupling capacitors adjacent to the appropriate VDD and VSS pins, and keep high-current switching nodes and motor-drive traces away from the MCU and sensitive analog inputs. Verify pin multiplexing before fixing connector locations because several I/O functions can be assigned to different pins through configuration registers.
Do not treat the I and E ordering suffixes as interchangeable without checking the production temperature requirement. The PIC24F08KA101-I/MQ and PIC24F08KA101T-E/MQ share the same core and package, but the ordered grade differs. Also avoid assuming that every peripheral can remain active in Deep Sleep: DSBOR, DSWDT, and RTCC have specific retention behavior, and the remaining timers, PWM channels, and communications blocks require explicit configuration and clock-gating review.
合規資訊
The manufacturer listing identifies the device as an active industrial-range microcontroller but does not provide explicit RoHS, REACH, halogen-free, lead-free, conflict-minerals, or automotive-qualification statements for this orderable configuration.
