PIC24F08KL201-I/MQ Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), working memory (RAM), and a rich set of peripherals. The PIC24F family sits in the 16-bit tier of the Microchip PIC taxonomy (PIC10/12/16 -> PIC18 -> PIC24 -> dsPIC33/dsPIC32) and is aimed at cost-sensitive applications that need more performance and code space than 8-bit PIC MCUs but want to avoid the cost of Cortex-M parts.
Key features include 12 channels of 10-bit ADC with internal bandgap reference, two analog comparators, one MSSP supporting both I2C and SPI, one CCP/ECCP module, one UART, four 16-bit timers, four 8-bit timers and the eXtreme Low Power nanoWatt XLP mode set. Core-independent peripherals (CIPs) such as the Configurable Logic Cell (CLC) and Peripheral Pin Select (PPS) offload glue logic from the CPU.
Architecture-wise the KL-series uses a 3-stage pipelined 16-bit modified-Harvard core with a 24-bit instruction word, single-cycle hardware multiply, and a 16-element × 16-bit working register array. The device operates from 1.8 V to 3.6 V and provides 15 GPIO with PPS mapping.
Typical applications include low-cost remote controls, sensor nodes, battery-powered IoT end-points, consumer white goods, and human-interface boards that previously used PIC18 silicon. Compared with the PIC18F series, KL parts add more code space at lower power and add PPS so the same 20-pin VQFN footprint can carry more protocols.
When designing with the KL series, budget Flash and RAM early - 8 KB / 512 B is tight for protocol stacks (BLE, USB) and is best used as a co-MCU. Provide 100 nF plus 10 uF decoupling close to the VDDV/VSS pairs and follow the recommended VQFN land pattern from the package datasheet.

Typical Applications
PIC24F08KL201-I/MQ is suitable for 6 applications: Battery-Powered IoT Sensor Node, Consumer Remote Control, Smart Home / Building Automation, Industrial Control / White Goods, Medical / Health Wearables, Cost-Sensitive Consumer HMI.
Battery-Powered IoT Sensor Node
The PIC24F08KL201-I/MQ fits battery-powered sensor nodes because of its nanoWatt XLP technology platform with sub-1 uA Deep Sleep current and integrated 12-channel 10-bit ADC. Its 8 KB Flash is enough for sensor-fusion glue logic and basic radio-host protocol hooks, and the 32 MHz / 16 MIPS core handles periodic reads without missing wake events. The 20-pin VQFN (5x5) package gives compact PCB area. Real consideration: budget Flash for protocol stack overhead and verify the analog comparator + CLC wake path at lowest supply voltage.
Recommended
Consumer Remote Control
The PIC24F08KL201-I/MQ is ideal for IR/RF remote controls thanks to its 8 KB Flash for protocol firmware, low-power Sleep modes, and CCP/ECCP module for accurate IR carrier generation. nanoWatt XLP means coin-cell remotes can survive multi-year standby without replacement. The 20-pin VQFN footprint keeps BOM area low and the CLC core-independent peripheral can wake the MCU from a key-press without software involvement. Use a 32.768 kHz crystal on SOSCO/SOSCI for RTCC-based scheduling.
Recommended
Smart Home / Building Automation
In smart-home edge nodes (PIR occupancy, CO2, leak sensors, smart locks) the PIC24F08KL201-I/MQ provides enough MIPS for on-device filtering, CLC-based glue logic, and PPS-mapped GPIO that simplifies PCB layout. The MSSP module supports I2C sensors and SPI peripherals simultaneously, and 256 B of EEPROM stores user preferences reliably across power cycles. Consideration: at high ambient temperatures the -I/MQ version is rated to 85C; for HVAC ducts or outdoor enclosures, choose PIC24F08KL201-E/MQ with 125C support.
Recommended
Industrial Control / White Goods
White-goods and industrial-control front-panel boards benefit from the PIC24F08KL201's 32 MHz core for HMI scan routines and the 10-bit ADC for sensing. The peripheral pin select feature lets the same PCB route UART, SPI and PWM to whichever pins match the chosen connector. nanoWatt XLP idle currents help meet EU Ecodesign standby targets. Watch the 1.8-3.6 V supply range - downstream actuators driven from 5 V or 12 V still need a separate driver rail.
Recommended
Medical / Health Wearables
Wearable health patches and patient monitors can use the PIC24F08KL201-I/MQ as a low-power co-MCU that aggregates sensor data, performs on-device filtering and forwards results over I2C/SPI to a BLE radio. Sub-microamp Deep Sleep enables multi-day wear time on a coin cell. The 10-bit ADC is sufficient for heart-rate or SpO2 reference designs when paired with a dedicated AFE such as the MCP9808 family. Plan EMI shielding carefully because the analog comparator is sensitive to nearby switching regulators.
Recommended
Cost-Sensitive Consumer HMI
Cost-sensitive consumer HMIs - small kitchen appliances, toys, fitness accessories - are the canonical use case for the PIC24F08KL201 family, giving 16 MIPS at 32 MHz with 8 KB Flash in a tiny VQFN-20 footprint. The MSSP supports SPI displays or I2C keypads, and the CLC peripheral replaces a few discrete logic gates around the MCU, lowering BOM cost. Use a UART bootloader for field upgrades so a non-isolated flash programmer is unnecessary in production.

Key Differentiators
- 8 KB Flash + 512 B RAM on a 20-pin VQFN is the largest code-space in the Microchip KL-family at this pin count (vs PIC24F04KL101T-I/MQ)
- nanoWatt XLP technology platform (sub-1 uA Deep Sleep) is the lowest-power idle option in the KL family (vs PIC24F08KA102-I/SS)
- Peripheral Pin Select on a 20-pin VQFN (vs PIC24F08KA102-I/SS)
Design Notes
Estimated: at VDD = 3.3 V, the PIC24F08KL201 draws ~1 mA per MIPS in active mode and ~30 uA/MHz idle. Deep Sleep current is sub-1 uA. Use a 100 nF ceramic bypass capacitor on VDD plus a 10 uF bulk capacitor within 5 mm of the VDD pin. For coin-cell designs, drive VDD from an MCP1640 boost regulator to keep the rail above 2.0 V under load - brown-out reset kicks in below ~1.8 V.
The 20-pin VQFN (5x5) package has an exposed thermal pad that MUST be soldered to the board ground plane. Use the manufacturer's recommended land pattern (non-solder-mask-defined pad) with thermal vias in a 3x3 grid under the e-pad to drop junction-to-ambient thermal resistance to ~30 C/W. Skipping the e-pad solder joint raises junction temperature and may cause ADC offset drift.
Do not exceed the absolute maximum VDD of 3.6 V - the KL-series is a 3.3 V part, not 5 V tolerant. If your board mixes 5 V peripherals, add a level translator such as the LTC4311 or use the PIC's internal weak pull-ups for slow I2C lines. Also note that PGEDx/PGECx programming pins are multiplexed with GPIO RB0/RB1 on most packages, so leave room for an ICSP header during prototype bring-up.
The MSSP peripheral supports both I2C and SPI but only one mode at a time; remap SDA/SCL via Peripheral Pin Select for board-routing flexibility. For 400 kHz I2C, add 2.2 kohm pull-ups to VDD (the KL bus pins cannot drive the rail internally). The 10-bit ADC is sensitive to supply noise, so route analog VDD through a ferrite bead and keep switching regulator traces away from the analog input traces.
Compliance Information
