PIC24F08KA101-E/P Overview
What is a 16-bit Flash MCU? A microcontroller (MCU) is a single-chip computer containing a processor core, memory, and programmable peripherals. A 16-bit Flash MCU uses a 16-bit data path, which doubles the arithmetic throughput of 8-bit MCUs at the same clock rate, while in-system programmable Flash memory eliminates the need for an external ROM. The PIC24F architecture belongs to the modified Harvard family and is widely used where higher computational performance than PIC16/PIC18 is required without migrating to a 32-bit core.
The PIC24F08KA101-E/P integrates the nanoWatt XLP (eXtreme Low Power) technology platform, including Deep Sleep mode with DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer) and RTCC (Real-Time Clock Calendar) that continue to operate in Deep Sleep, achieving typical currents below 1 uA in retention. The device runs at up to 32 MHz (16 MIPS) from an internal oscillator, has 18 general-purpose I/O pins, and includes a 10-bit 500 ksps ADC, comparators, timers, and multiple serial interfaces (UART, SPI, I2C).
The architecture uses a 3-stage pipeline with a hardware multiplier, providing deterministic interrupt response and single-cycle 16x16 MAC operations. The integrated voltage regulator accepts 1.8V to 3.6V supply and supports on-chip FVR (Fixed Voltage Reference) for ADC and comparator channels. Fail-safe clock monitoring and configurable oscillator startup extend reliability in noisy or battery-disconnected environments.
Typical applications include battery-powered sensor nodes, portable medical instruments, low-power wireless remote controls, energy-harvesting edge devices, and consumer products where sleep current dominates battery life. The DIP-20 package is also favored for through-hole prototype boards, educational labs, and easy field-replacement designs.
Designers should pay attention to the difference between -E (extended) and -I (industrial) temperature grades: -E is preferred for outdoor, automotive-cabin, or industrial installations that experience sustained temperatures above 85C. Always route AVDD/AVSS separately and place decoupling capacitors within 3 mm of each power pin.

Typical Applications
PIC24F08KA101-E/P is suitable for 6 applications: Battery-Powered Sensor Nodes, Portable Medical Instruments, Low-Power Wireless Remote Controls, Energy-Harvesting Edge Devices, Industrial Control Modules, Educational and Prototype Boards.
Battery-Powered Sensor Nodes
The PIC24F08KA101-E/P is a natural fit for wireless sensor nodes running on coin cells or AA batteries thanks to nanoWatt XLP Deep Sleep current below 200 nA with RTCC and DSWDT active. Its 8 KB Flash comfortably holds ZigBee/LoRa MAC stack stubs plus sensor drivers, while the 10-bit 500 ksps ADC with 9 channels handles multi-sensor sampling without an external MUX. Compared with a discrete RTC + supervisor design, integrating DSBOR and RTCC onto the MCU saves both PCB area and standby current, often extending battery life from months to years.
Recommended
Portable Medical Instruments
For handheld medical devices such as glucose meters, pulse oximeters and single-patient wearables, the PIC24F08KA101-E/P's extended -40C to +125C temperature grade and 16 MIPS throughput support accurate ADC sampling of biosignals. Its low Deep Sleep current is critical for IEC 60601-1-8 battery-life compliance, and the on-chip 10-bit ADC eliminates an external converter. The DIP-20 package also simplifies EMI/ESD pre-compliance testing because the through-hole pins give a more predictable reference plane than leadless SMD parts.
Recommended
Low-Power Wireless Remote Controls
Battery-operated RF remote controls for garage doors, lighting and consumer electronics benefit from the PIC24F08KA101-E/P's nanoWatt XLP sleep modes and wake-on-pin-change interrupts. The MCU's internal 8 MHz oscillator and on-chip UART/SPI peripherals directly interface with 433/868 MHz or sub-GHz transceivers without external crystals for many configurations. The 8 KB Flash holds typical RF protocol stacks (KEELOQ, proprietary) plus user customization, and the 18 I/O drive LED indicators and keypad matrices directly.
Recommended
Energy-Harvesting Edge Devices
Energy-harvesting designs powered by solar, vibration or thermal gradients require an MCU that can boot from microjoule budgets and idle at nanoamps. The PIC24F08KA101-E/P's nanoWatt XLP technology with DSBOR, DSWDT and RTCC keeps average current below 20 uA for typical duty cycles, while its 1.8V minimum VDD lets it run directly from a single-cell energy harvester without boost conversion. The 32 MHz performance gives enough headroom to run local edge-intelligence algorithms before transmitting summarized data upstream.
Recommended
Industrial Control Modules
In factory-automation modules, the PIC24F08KA101-E/P's -40C to +125C temperature grade ensures reliable operation near motors, heaters and unconditioned cabinets. Its 5 16-bit timers and 2 comparators make it suitable for closed-loop control of fans, pumps and small stepper motors without an external motion controller. The DIP-20 package simplifies field service because modules can be swapped with through-hole spare parts, reducing mean-time-to-repair.
Recommended
Educational and Prototype Boards
The PIC24F08KA101-E/P in DIP-20 remains a staple in university embedded-systems labs and DIY prototyping kits because the through-hole footprint fits standard 0.300 inch breadboards and the XLP features let students explore low-power design without complex debug setups. The 32 MHz core, 8 KB Flash and 1.5 KB SRAM cover textbook exercises on interrupts, timers, ADC and serial protocols. The -E temperature grade also lets the same board be used in outdoor experiments without rework.

Key Differentiators

- Includes I2C peripheral for sensor-bus designs (vs PIC24F08KA100-E/P)
- Larger EEPROM for data logging without external memory (vs PIC24F08KL101-I/P)
- True drop-in through-hole package for prototyping (vs PIC24F08KA101-I/SS)
Design Notes
Estimated: At 32 MHz from a 3.3 V supply the PIC24F08KA101-E/P typically draws 8-12 mA active; in Deep Sleep with RTCC on a 32.768 kHz crystal it falls to roughly 200 nA. For coin-cell designs, ensure total average current stays below 100 uA by duty-cycling the core and using peripheral wake events instead of polling. Place a 100 nF decoupling capacitor within 3 mm of VDD (pin 20) and a 10 uF bulk capacitor near the regulator output.
Route AVDD/AVSS as a star from the regulator with a ferrite bead if the ADC is in use, and keep analog traces short and guarded. The DIP-20 footprint gives generous clearance, but still maintain a 4-layer stack-up with a continuous ground plane under the IC body. Add a 4.7 kohm pull-up on MCLR/VPP (pin 1) for normal operation and use the ICSP pads (PGD1/PGC1 on RB1/RB0) for in-circuit programming without disturbing the layout.
Do not assume the /P variant is identical to the /SS or /SO variants - only the DIP-20 package code is pin-compatible as a drop-in. Verify your BOM against the Microchip product-page ordering code before mass-production programming. The 'E' temperature grade (-40C to +125C) is required for outdoor and automotive-cabin installations; using an 'I' grade part there will void the warranty and risk field failure.
Keep the 32.768 kHz crystal traces short (<5 mm) and surrounded by ground pour to minimize leakage into the RTCC domain. If you switch between the internal 8 MHz FRC and the crystal, allow 1 ms of software delay for oscillator stabilization. For RF-noise-prone boards, place the MCU on the opposite side of the PCB from any switching regulator and route a 4 mm wide ground moat between the two regions.
Compliance Information
RoHS and REACH compliant per Microchip product page declarations. The PDIP-20 package is MSL1 (no moisture-sensitive handling required). Not AEC-Q100 qualified; for automotive-cabin applications use a Q-graded PIC24F variant from Microchip's automotive portfolio. Halogen-free per JESD22-A114.
