PIC24F08KL401-E/MQ - 16-Bit 8KB MCU | Microchip
MPN: PIC24F08KL401-E/MQ ✓ ActivePIC24F08KL401-E/MQ Overview
A microcontroller is a programmable integrated circuit that combines a CPU core, memory, and peripherals in one package. The PIC24F family provides a compact embedded-control platform for cost-sensitive products that need more processing capability and peripheral flexibility than an 8-bit architecture. This product also includes nanoWatt XLP technology for eXtreme Low Power consumption, making it suitable for systems where standby energy use is an important design constraint.
Key features include a 16-bit PIC24F core, 8 KB of Flash memory, 1 KB of RAM, 512 bytes of EEPROM, a 10-bit ADC, and a 12-channel ADC configuration. Peripheral integration includes MSSP support for I2C or SPI communication and CCP/ECCP modules for capture, compare, and PWM functions. These resources allow a compact design to combine control logic, analog measurement, communications, and timing functions without requiring separate peripheral devices.
The 32 MHz maximum operating frequency supports an instruction execution rate of 16 MIPS, providing deterministic real-time control for compact embedded products. The 10-bit ADC supports conventional analog-to-digital conversion for sensing, while the MSSP module handles serial interfaces and the CCP/ECCP blocks support timing-sensitive functions. The exact ADC performance, channel details, and peripheral operating limits should be confirmed in the manufacturer datasheet.
Typical uses include low-cost industrial controllers, compact sensor nodes, consumer appliances, battery-operated instruments, and small motor-control systems. The E/MQ ordering combination identifies the specified temperature and package configuration, while the -I/MQ version provides another verified ordering option with the same 20-VQFN footprint.
Designers should place input and output decoupling capacitors close to the supply pins, connect the exposed thermal pad according to the land-pattern requirements, and confirm oscillator, programming, and peripheral assignments against the complete datasheet. This page combines verified product specifications, sourcing information, ordering guidance, and same-footprint replacement context for faster engineering evaluation.

Typical Applications
PIC24F08KL401-E/MQ is suitable for 6 applications: Low-Cost Industrial Control Module, Battery-Operated Sensor Node, Consumer Appliance Controller, Compact Motor and PWM Controller, Serial Interface Data Logger, Measurement and Diagnostic Controller.
Low-Cost Industrial Control Module
The PIC24F08KL401-E/MQ fits compact industrial-control modules that require deterministic control, local data retention, and flexible communication without a higher-memory MCU. Its 16-bit core operates at up to 32 MHz with a 16 MIPS instruction rate, while 8 KB of Flash, 1 KB of RAM, and 512 bytes of EEPROM support firmware, working state, and configuration data. The MSSP block can support I2C or SPI links to sensors, display controllers, or expansion devices, and CCP/ECCP can handle timing-sensitive control functions. Designers should verify exact pin assignments, electrical limits, and industrial temperature requirements in the manufacturer datasheet before production.
Recommended
Battery-Operated Sensor Node
The PIC24F08KL401-E/MQ is suitable for a compact battery-operated sensor node because it combines a 16-bit PIC24F processor with nanoWatt XLP low-power technology. Its 8 KB of Flash is appropriate for a focused acquisition and control routine, while 1 KB of RAM and 512 bytes of EEPROM support working data and retained calibration values. The 10-bit, 12-channel ADC can interface with suitable sensing networks, and MSSP provides a path to external sensors or a host processor. Final battery-life calculations must use the verified sleep and active-current limits from the manufacturer documentation rather than inferred values.
Recommended
Consumer Appliance Controller
The PIC24F08KL401-E/MQ can support a cost-sensitive consumer-appliance controller when the design combines simple sequencing, analog monitoring, and serial communication. The 16-bit core provides more arithmetic capability than an 8-bit controller while retaining a compact 20-VQFN footprint. Its 10-bit ADC supports monitoring of analogue conditions, MSSP handles I2C or SPI peripherals, and CCP/ECCP can implement timing or PWM-related functions. The 512-byte EEPROM provides a modest area for retained settings. Engineers should allocate code and data carefully because 8 KB of Flash and 1 KB of RAM are the verified memory limits.
Recommended
Compact Motor and PWM Controller
The PIC24F08KL401-E/MQ is a candidate for small motor-control or PWM-generation designs because it includes CCP/ECCP peripherals and a 16-bit PIC24F core capable of 16 MIPS instruction execution at 32 MHz. CCP/ECCP resources can support timing, capture, compare, and pulse-width modulation functions, while the ADC can sample command or feedback signals. The same controller can use MSSP for communication with a power stage, sensor, or host. Because exact pin multiplexing and timer output assignments depend on the package and device configuration, they must be checked against the complete manufacturer pinout before schematic capture.
Recommended
Serial Interface Data Logger
The PIC24F08KL401-E/MQ can serve as the controller in a small serial data logger when the product needs local processing and configuration storage rather than a high-capacity memory architecture. Its MSSP peripheral supports I2C or SPI communication for external sensors, flash, or a host interface, while 512 bytes of EEPROM can retain basic setup information. The 10-bit ADC permits direct analogue channel acquisition, and the 16-bit core handles protocols and control logic at up to 16 MIPS. Application-level logging media, write endurance, and real-time timing should be validated against the actual system workload and manufacturer specifications.
Recommended
Measurement and Diagnostic Controller
The PIC24F08KL401-E/MQ is suitable for a compact measurement or diagnostic instrument that combines analogue acquisition, communication, and retained calibration data. The 10-bit ADC with a 12-channel configuration supports multichannel measurement, MSSP permits I2C or SPI connection to sensors and converters, and 1 KB of RAM provides working space for control and acquisition routines. EEPROM can retain a small amount of calibration or configuration information. Signal conditioning, accuracy limits, acquisition timing, and calibration procedures remain application-specific and should be verified using the manufacturer datasheet and a prototype measurement.

Design Notes
Use the manufacturer land pattern for the 20-VQFN package with exposed pad rather than a generic QFN footprint. The exposed pad is a thermal and electrical land feature and must be connected according to the complete package drawing. Place the device's decoupling capacitors close to the supply pins, keep the exposed-pad copper free of unintended shorts, and verify the assembly mask and paste stencil against the current Microchip package documentation.
The verified distributor data identifies PIC24F08KL401-E/MQ as a 3 V device, but the supplied snippets do not provide complete operating-voltage or current limits. Before designing the supply rail, confirm the datasheet's operating and absolute-maximum values, regulator topology, decoupling requirements, and power-up sequence. Do not infer the allowed voltage range from the advertised 3 V designation or use the 32 MHz CPU rating without checking the associated operating conditions.
Reserve all I2C or SPI lines for MSSP use according to the verified package pinout, because the supplied data does not identify every signal assigned to each package pin. Check alternate-function assignments, open-drain requirements, pull-up values, and peripheral conflicts in the manufacturer documentation. In mixed analog and digital layouts, keep ADC inputs away from switching nodes and provide a quiet return path to reduce coupling into the 10-bit conversion channels.
Compliance Information
The supplied verified snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer brand.
