PIC24F08KL201-E/P Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a configurable set of peripheral interfaces. Within the broader taxonomy, the PIC24F08KL201 belongs to the 16-bit MCU class (16-bit data path) -> CISC Harvard-architecture MCU family -> microcontroller -> embedded processor -> semiconductor IC. Its enhanced mid-range PIC24F core supersedes legacy PIC18F parts while remaining code-compatible with the PIC18 peripheral set, easing migration of legacy code and shortening time-to-market.
Key features include nanoWatt XLP™ sleep currents in the microampere range, flexible clocking from the internal 8 MHz FRC (with PLL to 32 MHz) or an external crystal, on-chip 3.3 V regulator for single-rail operation, and a 10-bit ADC capable of 12-channel conversion for sensor reading. The MSSP peripheral supports both I²C (Master/Slave, 7-bit/10-bit addressing) and SPI (Master/Slave) communication, enabling digital sensor and EEPROM interfacing with no external glue logic.
The device operates from 1.8 V to 3.6 V (typically 3.3 V), with brown-out reset, watchdog timer, and code-protect features. Programming is supported through ICSP™ (In-Circuit Serial Programming) and JTAG is not present. The 20-pin PDIP package is a through-hole form factor preferred for prototyping, breadboarding, and low-volume production where socketed replacement or hand rework is desirable.
Typical applications include low-cost sensor nodes, battery-powered data loggers, simple home appliances, and industrial control modules. The wide -40 °C to +125 °C range, XLP™ low-power modes, and small Flash footprint make it ideal for cost-sensitive designs migrating from PIC16/PIC18 to a 16-bit core. For new designs that do not need through-hole pins, the PIC24F08KL201-E/MQ (QFN-28) variant is recommended; the -E/P here remains optimal for breadboard-based prototypes and socketed deployments.
When designing with this part, ensure decoupling capacitors are placed within 5 mm of the VDD pin, verify the MSSP pin mapping matches your target I²C/SPI slave before PCB layout, and select between the internal FRC and an external crystal based on UART/I²C timing tolerance. This page combines Microchip datasheet specifications, current distributor pricing, and drop-in same-family alternatives so engineers can evaluate, source, and design with the PIC24F08KL201-E/P without tab-switching.

Aplicaciones típicas
PIC24F08KL201-E/P es adecuado para 6 aplicacións: Battery-Powered Sensor Node, Industrial Control Module, Low-Cost Consumer Appliance, Automotive Body Electronics (Non-Safety), Remote Control / IR Transmitter-Receiver, Educational / Hobbyist Prototyping.
Battery-Powered Sensor Node
The PIC24F08KL201-E/P is an excellent fit for battery-powered sensor nodes because its nanoWatt XLP™ technology delivers sub-microampere deep-sleep currents while the 32 MHz / 16 MIPS PIC24F core wakes quickly to process sensor reads and transmit via I²C/SPI MSSP. The 12-channel 10-bit ADC samples thermistor, photo, or voltage-divider sensors directly, eliminating external analog front-end parts. With 8 KB of Flash the device comfortably holds a state-machine plus an I²C/SPI driver for an external sensor or BLE module. Compared with a Cortex-M0+ part at the same price point, the KL201 offers deeper sleep modes and a more deterministic 1-cycle instruction execution, simplifying power budgeting in long-life battery designs (target 1-3 years on a single CR2032).
Recomendado
Industrial Control Module
The PIC24F08KL201-E/P suits industrial control modules requiring extended-temperature operation from -40 °C to +125 °C, including relay drivers, optocoupler interfacing, and 4-20 mA loop signal conditioning. The 32 MHz core executes single-cycle instructions, making PID loops and time-critical switch debouncing deterministic. The 12-channel 10-bit ADC reads up to 12 analog inputs (e.g., temperature, pressure, voltage monitoring), while the MSSP peripheral drives an I²C display or SPI DAC for HMI output. The 20-pin PDIP through-hole package is socket-friendly for factory-floor service replacement. Compared with a Cortex-M0 alternative, the KL201 wins on cost, low BOM, and proven long-term Microchip lifecycle support for industrial applications running 10+ years.
Recomendado
Low-Cost Consumer Appliance
The PIC24F08KL201-E/P is a strong fit for low-cost consumer appliances such as coffee machines, microwave user interfaces, washing-machine control boards, and small kitchen gadgets. Its 8 KB Flash holds UI state machines and EEPROM emulation, while the 512 B RAM is ample for keypad scanning, LED multiplexing, and short timers. The 1.8-3.6 V supply range allows direct connection to 3.3 V digital sensors or button-matrix circuits without external level shifters. The 20-pin PDIP package is easy to hand-assemble in low-volume SKUs and is preferred by some manufacturers for its socket-friendly replacement during service. Compared with PIC18F legacy designs, the 16-bit PIC24F core doubles code efficiency for the same memory size.
Recomendado
Automotive Body Electronics (Non-Safety)
The PIC24F08KL201-E/P fits non-safety automotive body electronics such as interior lighting controllers, seat-adjust switches, mirror-fold modules, and HVAC panel interfaces. The -E temperature grade covers the under-dash automotive environment (-40 °C to +125 °C), and the nanoWalt XLP™ modes help the module survive long key-off periods without draining the 12 V battery. The MSSP drives I²C-controlled LED drivers or SPI EEPROM for fault logging. For safety-critical ECUs (airbag, ABS, steering) use a dedicated AEC-Q100-qualified part such as PIC18F46K22-I/P; the KL201 is appropriate only for non-safety body controllers. Compared with a 32-bit Cortex-M0 part, the KL201 keeps BOM cost low for high-volume interior applications.
Recomendado
Remote Control / IR Transmitter-Receiver
The PIC24F08KL201-E/P fits handheld remote controls and IR/Sub-GHz receiver decoders due to its low active power, fast wake-up from sleep, and small code footprint. The CCP peripheral generates precise carrier frequencies for IR transmission (36 kHz/38 kHz/40 kHz), while the 16-bit timer captures IR decoder edge timing. The 8 KB Flash is ample for RC5/RC6/Sony/NEC protocol stacks plus button-mapping logic. Battery life is dominated by LED/IR transmit current, but nanoWalt XLP™ keeps idle quiescent current below 1 µA, enabling multi-year coin-cell operation. Compared with a PIC16F baseline, the 16-bit core executes the protocol stack 2x faster, freeing cycles for button scanning and LED driving.
Recomendado
Educational / Hobbyist Prototyping
The PIC24F08KL201-E/P is ideal for educational and hobbyist prototyping because the 20-pin PDIP through-hole form factor drops directly into a breadboard or perfboard. Students can practice C programming with Microchip's free MPLAB X IDE and XC16 compiler, no commercial license required. The 8 KB Flash holds a real project (e.g., a digital thermometer, motor controller, or I²C scanner), and the 12-channel ADC supports multiple analog sensors simultaneously. The ICSP™ programming header allows in-circuit debugging and re-flashing without removing the chip. Compared with surface-mount QFN variants, the PDIP-20 package lowers the barrier for beginners who lack reflow equipment.

Notas de diseño
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 20), and add a 10 µF bulk capacitor at the regulator output feeding the MCU rail. According to Microchip's PIC24F hardware design checklist, both VDD/VSS pairs must each have their own local decoupling. For battery-powered designs using nanoWalt XLP™ deep sleep, switch off any external sensors via a GPIO-driven MOSFET before entering Sleep mode to achieve the sub-µA standby target. Verified: at 3.3 V VDD with all peripherals off, the KL201 enters Sleep at <1 µA per datasheet.
The 20-pin PDIP package is through-hole, but pin-1 orientation still follows the standard DIP convention (notch up, pin 1 at top-left). Route the ICSP™ programming header (PGEDx/PGECx/MCLR/VDD/VSS) to a 6-pin 0.1 inch header near the MCU for in-circuit debugging and re-flashing. Use a 4.7 kΩ pull-up on MCLR. According to the Microchip PIC24F programming specification, MCLR must NOT be left floating; tie it through the pull-up to VDD to keep the part out of permanent reset.
The MSSP peripheral can operate as either I²C or SPI but not both simultaneously - select the mode in firmware and route the appropriate SDA/SCL or SDI/SDO/SCK pins. For I²C bus, add 4.7 kΩ pull-ups on SDA and SCL to VDD; for SPI, ensure the SCK rise/fall time is <50 ns (use shorter traces or series resistors). According to the Microchip PIC24F family reference manual, the MSSP baud rate generator must be configured before enabling the peripheral, otherwise the bus may hang in an undefined state.
Estimated: at 3.3 V with the MSSP enabled and a 100 kHz I²C bus, the KL201 active current is ~3-5 mA - 100x higher than sleep. Plan the duty cycle carefully for battery life (e.g., wake every 5 s for 10 ms = 0.2% active duty, average current stays near 10 µA). Also, do not exceed the absolute maximum VDD of 4.0 V or the ESD rating on any pin; the KL201 is a 3.3 V part and will latch up if 5 V logic signals are applied without a level translator. According to the Microchip datasheet, the MCLR pin has a 5 V tolerant input option via the appropriate configuration bit.
