PIC24F04KL101-E/MQ 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, plus configurable peripherals. The PIC24F KL1 family targets cost-sensitive 8- to 16-bit migration with familiar PIC18 peripherals such as MSSP (I2C/SPI) and CCP, allowing designers to step up to 16-bit performance without abandoning the PIC18 toolchain. As part of the broader PIC24F family -> 16-bit MCU -> microcontroller -> embedded controller hierarchy, the KL1 sits in the cost-optimized branch.
Key features of the PIC24F04KL101-E/MQ include 4KB self-programmable flash with ECC, 512B SRAM, a 9-channel 10-bit ADC, two analog comparators, MSSP supporting I2C/SPI, one UART, two CCP modules, and a 32 kHz RTCC for real-time clock operation. The device supports 1.8V to 3.6V VDD with on-chip LDO, eliminating the need for external regulators.
Architecture details: the KL1 uses a 16-bit modified Harvard core with single-cycle multiply and divide, 16 working registers, and a deterministic 7-deep interrupt stack. XLP technology includes Sleep, Deep Sleep, and Retention modes with sub-uA quiescent current and fast wake-up, enabled by the on-chip RTCC and a hardware Windowed Watchdog Timer.
Typical applications include coin-cell and battery-powered sensor nodes, low-cost remote controls, energy-harvesting IoT endpoints, industrial sensor transmitters, and automotive accessory modules (a qualified variant exists in the same family). The -E extended temperature grade makes it suitable for under-hood and outdoor environments.
For designs, ensure VDD decoupling with at least one 100 nF + one 10 uF bulk capacitor placed close to the pins, route the ICSP clock/data lines cleanly, and observe the MCLR pull-up timing requirements for reliable in-circuit programming.

主な用途
PIC24F04KL101-E/MQ の用途: 6 件s: Coin-Cell Battery Sensor Endpoints, Low-Cost Remote Controls, Industrial Sensor Transmitters, Energy Harvesting IoT Nodes, Automotive Accessory Modules, Consumer Appliance User Interfaces.
Coin-Cell Battery Sensor Endpoints
The PIC24F04KL101-E/MQ's nanoWatt XLP Deep Sleep mode draws sub-microamps while retaining RAM, RTCC, and interrupt-on-pin capability, enabling multi-year coin-cell operation. The 4KB flash holds calibration tables, sleep/wake state machines, and BLE/Zigbee protocol stacks for periodic sensor uplinks.
おすすめ
Low-Cost Remote Controls
With 32 MHz / 16 MIPS throughput and integrated MSSP (I2C/SPI), the PIC24F04KL101-E/MQ handles RF encoder ICs and keypad matrix scanning without external logic. The 1.8V-3.6V VDD range accepts a single CR2032 cell directly, eliminating boost converters in handheld transmitters.
おすすめ
Industrial Sensor Transmitters
The -E Extended temperature grade (-40C to +125C) and 9-channel 10-bit ADC make the PIC24F04KL101-E/MQ suitable for factory-floor 4-20mA sensor bridges, RTD conditioning, and process monitoring. Hardware Windowed Watchdog prevents lockup in unattended industrial environments.
おすすめ
Energy Harvesting IoT Nodes
Sub-microamp Deep Sleep and fast wake-up from RTCC make the PIC24F04KL101-E/MQ a fit for solar or vibration energy harvesting circuits where average power is critical. The on-chip LDO accepts the variable output of harvesters without external regulation.
おすすめ
Automotive Accessory Modules
The -E Extended grade (-40C to +125C) and 32 MHz throughput suit cabin and under-hood accessory modules such as lighting controllers, seat heaters, and HVAC dampers. For safety-critical applications requiring AEC-Q100, Microchip offers -Q1 qualified variants of the KL1 family in identical footprints.
おすすめ
Consumer Appliance User Interfaces
Two CCP modules drive PWM for LED backlighting and buzzer feedback, while the MSSP interfaces with capacitive touch or segment LCD drivers. The 4KB flash holds state-machine UI logic and the 1.8V-3.6V VDD simplifies integration with battery or mains-derived supplies in white goods.

設計ノート
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 9) with the ground return to VSS (pin 10). Add a bulk 10 uF capacitor on the same VDD rail. For battery-powered designs operating from Deep Sleep, the bulk capacitor supports the wake-up transient without causing VDD droop.
The exposed thermal pad (pin 20) MUST be soldered to a copper pad on the PCB connected to VSS for mechanical stability and thermal dissipation. Use multiple thermal vias under the EP to the ground plane to improve heat spreading. For VQFN packages, skipping the EP solder connection can cause reliability and thermal failures.
Do not float the MCLR pin (pin 19); always pull it up to VDD through a resistor (typically 10 kOhm). A floating MCLR can cause spurious resets or programming failures. For ICSP operation, ensure the ICSPDAT and ICSPCLK lines are not pulled low by external circuitry during programming.
Route the 32 kHz crystal traces (if used) symmetrically and keep them short with a ground guard ring to reduce EMI pickup. Place the crystal load capacitors close to the OSC1/OSC2 pins. For high-noise environments, use the internal oscillator instead to reduce BOM and EMI susceptibility.
コンプライアンス情報
RoHS and REACH compliant per Microchip product page. The -E/MQ variant carries Extended industrial temperature grade (-40C to +125C) but is NOT AEC-Q100 qualified; for AEC-Q100 qualified versions look for Microchip's automotive-grade -Q1 suffix variants in the same PIC24F04KL101 family.
