PIC24F16KA101-E/MQ - 16-Bit 32MHz XLP MCU | Microchip
料号： PIC24F16KA101-E/MQ ✓ 量产中PIC24F16KA101-E/MQ 概述
A microcontroller is a programmable control component that integrates a processor core, memory, and peripherals on one semiconductor die. The PIC24F16KA101 belongs to the PIC24F family of 16-bit RISC microcontrollers, which combine digital control, communications, timing, and analog-conversion functions in compact embedded devices. Its XLP, or eXtreme Low Power, architecture is intended for systems where standby energy use is as important as active processing performance.
Key features include 16 KB of flash program memory organized as 5.5K x 24 words, 1.5K x 8 RAM, 18 general-purpose I/O pins, and operation up to 32 MHz. The verified product listings also identify internal oscillators, 512 bytes of EEPROM, and serial peripherals including I2C, SPI, and UART/USART. The -E/MQ ordering code corresponds to the 20-pin VQFN exposed-pad package with tube packaging as listed by the distributor source.
The PIC24F16KA101-E/MQ combines a 16-bit architecture with the XLP feature set for embedded control rather than high-throughput application processing. Flash memory supports in-system firmware updates, while the exposed thermal pad improves heat transfer from the device to the PCB. This combination is useful where compactness, low standby current, and mixed analog/digital control are more important than a large software ecosystem.
Typical applications include battery-operated sensors, compact industrial monitors, low-power sensing nodes, portable measurement instruments, and embedded appliances. The internal oscillator allows a design to avoid an external crystal where timing tolerance permits, while I2C, SPI, UART/USART, PWM, and A/D converter resources support sensor acquisition, local communication, and actuator control.
Designers should confirm the exposed-pad land pattern and connect the thermal pad to the appropriate ground plane. Decoupling capacitors should be placed close to the supply pins, programming and debug interfaces should follow the device programming guidance, and unused inputs should be handled to prevent unintended current consumption in low-power states.
This page synthesizes manufacturer and distributor data, explicitly flags unverified technical fields, compares same-footprint drop-in variants, and adds practical low-power PCB and design guidance beyond a basic distributor specification table.

典型应用
PIC24F16KA101-E/MQ 适用于 6 应用s: Battery-Powered Sensor Node, Portable Measurement Instrument, Low-Power Industrial Monitor, Smart Home Control Module, Battery-Powered Data Logger, Automotive Accessory Controller.
Battery-Powered Sensor Node
PIC24F16KA101-E/MQ fits compact battery-operated sensing equipment because its PIC XLP architecture targets low standby consumption and includes deep-sleep DSBOR and DSWDT capabilities. The 16-bit core operating up to 32 MHz can sample inputs, filter measurements, and supervise sensor state without requiring a larger processor. Its 16 KB flash stores application firmware and configuration data, while 1.5 KB RAM supports short working buffers. The 20-VQFN exposed-pad package also leaves more PCB area than a larger leaded device. For best results, keep the sensor and radio duty cycle low, disable unused peripherals before sleep, and confirm wake-time current and leakage from the manufacturer power specifications.
推荐
Portable Measurement Instrument
PIC24F16KA101-E/MQ is suitable for portable meters and calibration equipment that combine local sensing with serial data transfer. The 32 MHz maximum speed provides useful control bandwidth, and the 512-byte EEPROM can retain calibration constants or configuration records. Its listed I2C, SPI, and UART/USART peripherals support sensors, displays, and host communication, while the A/D converter supports analog input conditioning. The 20-VQFN exposed-pad package is useful in compact handheld layouts, although the exposed pad must be connected according to the official land pattern. Validate input noise, reference stability, and LCD or radio activity against the required measurement accuracy before production release.
推荐
Low-Power Industrial Monitor
PIC24F16KA101-E/MQ supports compact industrial monitors that periodically inspect sensors and then return to a low-power state. Its XLP family features include DSBOR, DSWDT, and RTCC, while the 18 available I/O pins can connect discrete inputs, status indicators, and actuators. The -E/MQ grade is identified in the verified distributor data as automotive-oriented, making it worth evaluating for harsh environments after confirming its exact temperature limits and qualification records. Use UART/USART or SPI for a host controller, I2C for sensors, and the A/D converter for analog process values. Design isolation, surge protection, and grounding at the board level rather than relying on the microcontroller for external fault-energy protection.
推荐
Smart Home Control Module
PIC24F16KA101-E/MQ can serve as the local controller in a small smart-home actuator or environmental-control module. Its 16-bit PIC architecture handles digital logic and protocol servicing, while I2C connects temperature or light sensors, SPI supports displays or memory, and UART/USART provides a host or module link. The compact 20-VQFN package is advantageous for space-constrained enclosures, while XLP modes can reduce standby demand when the module is idle. Power switched relays or solenoids must use suitable driver circuitry rather than direct MCU pins. Firmware should include debouncing, fail-safe states, and brownout-aware output defaults so the module remains predictable when the supply rail dips.
推荐
Battery-Powered Data Logger
PIC24F16KA101-E/MQ is well matched to periodic data-logging systems because it combines 32 MHz processing, 16 KB flash, and XLP low-power modes in a compact package. The MCU can wake on a timer, read an analog or digital sensor, timestamp and store a record, then return to deep sleep. Its internal oscillator can reduce external clock-component count, although calibration and timing tolerance must be checked against the logger specification. The 512-byte EEPROM is useful for counters, sequence markers, or compact configuration blocks, but the 16 KB flash also constrains firmware and data volume. For sustained logging, use a separate nonvolatile storage component or compressed data format and verify write endurance before defining the retention interval.
推荐
Automotive Accessory Controller
PIC24F16KA101-E/MQ is a candidate for compact automotive accessory controllers because the verified ordering information describes the -E/MQ device as automotive and the family provides XLP low-power features for ignition or battery-powered systems. Its 16-bit core, A/D converter, and serial peripherals can supervise switches, sensors, and body modules while limiting idle consumption. The 20-VQFN exposed-pad package requires careful land-pattern and thermal implementation, and all external loads need automotive-appropriate protection. Before release, verify the exact -E grade temperature limits, AEC-Q100 status, and any required qualification records in Microchip documentation. Do not infer automotive qualification from the ordering code alone.

设计说明
Use the official 20-VQFN exposed-pad drawing rather than a generic 20-pin footprint. Place the input and decoupling capacitors close to their associated supply pins, keep the exposed pad on a solid ground plane, and use the manufacturer-recommended thermal-via arrangement. Confirm the pad, lead, mask, and paste geometry in CAD before fabrication because an incorrectly merged or oversized exposed pad can create solder defects or alter thermal performance.
Treat the 2.5 V/3.3 V operating designation as a system-level constraint and verify the exact supply range from the manufacturer datasheet before selecting regulators or peripherals. Provide local decoupling, control return current through the ground plane, and avoid switching-node copper beneath sensitive analog inputs. If the MCU controls relays, motors, or solenoids, isolate those loads with drivers and protection so transients do not couple directly into the supply or I/O pins.
Do not substitute the -I/MQ suffix for -E/MQ solely because the VQFN footprint matches. The verified excerpts establish identical core speed and memory but do not provide the numeric temperature ranges or qualification records for either suffix. Review the ordering guide for grade limits, temperature qualification, and product status. In low-power firmware, also disable unused peripherals and configure unused I/O states to avoid leakage that can invalidate battery-life estimates.
合规信息
The supplied excerpts identify the -E/MQ ordering option as automotive but do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown rather than being inferred.
