PIC24F04KL101-E/SS - 16-Bit 32MHz 4KB MCU | Microchip Technology
N.º da peça: PIC24F04KL101-E/SS ✓ AtivoPIC24F04KL101-E/SS Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one compact device. This MCU belongs to the PIC24F family of 16-bit flash microcontrollers and provides a practical bridge between simple 8-bit control and more capable embedded processing. Its low-power XLP architecture is useful where battery life, standby consumption, or thermally constrained operation matters. The 4 KB Flash capacity is appropriate for compact control firmware rather than resource-intensive applications.
The PIC24F04KL101-E/SS combines a 32 MHz core with 512 B of RAM and 4 KB of Flash memory. Its MSSP block provides I2C and SPI connectivity for sensors, displays, memories, and other serial peripherals. CCP modules support capture, compare, and PWM-related control functions. These resources make the device applicable to compact industrial controllers, low-cost consumer products, building controls, instrumentation, and battery-powered monitoring equipment.
The -40°C to +125°C temperature range shown in the verified product data supports operation across industrial and extended-temperature environments. The 20-SSOP package provides a small, surface-mount form factor suitable for high-density designs. Programming and debugging support include the PIC24F04KL101 device support information identified by Northern Software and Elnec in the supplied search results, allowing engineers to confirm programmer and adapter compatibility before production use.
For new designs, verify the complete electrical limits, clock configuration, peripheral pin multiplexing, and programming requirements in the Microchip PIC24F04KL101 datasheet. The principal trade-off is limited memory capacity: 4 KB of Flash and 512 B of RAM favor compact control logic over feature-heavy applications. If the board already uses the PIC24F04KL101 footprint and 20-SSOP package, this exact ordering code is the preferred drop-in choice.
This product page combines verified manufacturer and distributor information, observed pricing, application guidance, and drop-in replacement analysis. It highlights practical constraints for firmware size, serial-interface integration, temperature range, programming support, and PCB reuse rather than repeating only the basic catalogue description.

Aplicações típicas
PIC24F04KL101-E/SS é adequado para 7 aplicaçãos: Low-Cost Industrial Control Modules, Battery-Powered Sensor Nodes, Serial Sensor and Metering Interfaces, Building and HVAC Controls, Consumer Appliance Interfaces, Programmable Logic and Timing Control, Instrumentation and Communication Bridges.
Low-Cost Industrial Control Modules
The PIC24F04KL101-E/SS fits compact control modules that need more responsiveness than an 8-bit MCU while keeping memory and board area modest. Its 16-bit architecture, 32 MHz operating frequency, 4 KB of Flash, and 512 B of RAM are sufficient for compact supervisory logic, state machines, and input/output coordination. The -40°C to +125°C range supports extended-temperature industrial environments. Designers should size firmware conservatively, use the CCP peripherals for timing functions, and validate worst-case latency under the selected clock configuration.
Recomendado
Battery-Powered Sensor Nodes
The PIC24F04KL101-E/SS is appropriate for small battery-powered sensor nodes because nanoWatt XLP supports low-power operating strategies and the 512 B of RAM is sufficient for compact sampling logic. Its MSSP block can connect an I2C or SPI sensor while the 32 MHz core handles acquisition sequencing. Battery-life improvements depend on correct use of sleep modes, peripheral shutdown, and wake-up software. Firmware should avoid unnecessary polling and verify each low-power current specification in the manufacturer datasheet.
Recomendado
Serial Sensor and Metering Interfaces
The PIC24F04KL101-E/SS works well in metering and sensor-interface products requiring both I2C and SPI connectivity through its MSSP peripherals. A single MCU can manage an I2C sensor, an SPI transceiver, and local digital outputs while its CCP modules provide timing or PWM functions. The 4 KB Flash limit favors focused acquisition firmware rather than elaborate protocol stacks. Confirm simultaneous peripheral use, alternate-function pin assignments, and bus timing against the datasheet before finalizing the PCB.
Recomendado
Building and HVAC Controls
PIC24F04KL101-E/SS can support small building-control products that coordinate digital inputs, serial sensors, and actuator timing. Its 16-bit core and 32 MHz frequency provide efficient control-loop execution, while MSSP enables connection to temperature, humidity, or occupancy modules and CCP supports timing-based outputs. The 20-pin SSOP package assists compact panel-board construction. For safety-related or long-lifetime installations, verify regulatory requirements, watchdog behavior, and the complete electrical limits independently of the family-level product summary.
Recomendado
Consumer Appliance Interfaces
The PIC24F04KL101-E/SS is suitable for cost-sensitive appliance and consumer-product interface boards that need reliable serial control and modest local processing. Its 4 KB Flash and 512 B of RAM target compact user-interface, keypad, display, or motor-control coordination functions rather than graphics-heavy workloads. The 2 V / 3.3 V description aligns it with modern low-voltage embedded systems. Use the 20-SSOP footprint directly and verify startup, reset, and programming behavior before committing to a high-volume control board.
Recomendado
Programmable Logic and Timing Control
PIC24F04KL101-E/SS can implement compact programmable timing and logic-control functions where CCP peripherals and fast general-purpose I/O provide useful event handling. The 16-bit architecture is advantageous for counters, debounce logic, and deterministic sequencing compared with many simple 8-bit controllers. Its 32 MHz operating speed supports responsive input polling and output updates. Designers should reserve timer resources carefully, avoid relying on tight margins from the 4 KB code-memory limit, and verify exact timer features in the device datasheet.
Recomendado
Instrumentation and Communication Bridges
PIC24F04KL101-E/SS can act as a small protocol-conversion or instrument-control bridge when the design involves one or two serial links and modest local logic. MSSP support allows I2C and SPI peripherals to coexist, while the 20-SSOP package helps minimize board footprint. A companion transceiver such as an RS-232 interface can extend external connectivity, although the exact electrical standard and isolation requirements must match the application. Firmware capacity, protocol timing, and peripheral pin conflicts require early partitioning because only 4 KB of Flash is available.

Notas de projeto
Design the supply around the verified 2 V / 3.3 V description and confirm the exact operating range, current limits, and power-consumption curves in the Microchip PIC24F04KL101 datasheet. Place the MCU supply decoupling capacitors directly beside the appropriate power and ground pins, keep sensitive traces short, and provide clean return paths. Low-power behavior should be measured with the same peripheral and I/O states planned for production rather than estimated from the nanoWatt XLP name alone.
Use the manufacturer 20-pin SSOP land pattern and preserve the verified package dimensions and pin numbering. Avoid placing test pads or tall components that interfere with the narrow leads. Because programming and debug interfaces often share pins with application functions, reserve the required programming access in the connector and test-point layout. Verify the final footprint against the current package drawing rather than scaling it from a generic SSOP drawing.
Do not treat a similar package or PIC24F family number as proof of drop-in compatibility. This device has only 4 KB of Flash and 512 B of RAM, so large protocol libraries, logging buffers, or layered software can exhaust its resources. Keep the build map under review, confirm MSSP and CCP pin multiplexing, and validate reset, clock, and programming behavior on early hardware before committing to production quantities.
