PIC24F08KM204-E/MV - 16-bit XLP MCU, 8KB Flash, 48-UQFN | Microchip

The Microchip Technology PIC24F08KM204-E/MV is a 16-bit PIC® XLP™ 24F microcontroller integrating 8 KB Flash program memory (organized 2.75K x 24), 2 KB SRAM, and 512 bytes of EEPROM in a 48-pin UQFN (6x6 mm) package. It operates at up to 32 MHz CPU clock and is built on a true eXtreme Low Power architecture that makes it ideal for energy-harvesting and battery-powered embedded designs. The 'E' suffix indicates an extended temperature grade of -40°C to +125°C, and the 'MV' package code designates the 6x6 mm UQFN surface-mount package. What is a PIC24F XLP microcontroller? PIC24F is Microchip's 16-bit Modified Harvard MCU family, positioned between 8-bit PIC16/PIC18 and 32-bit PIC32 in the broader microcontroller taxonomy: microcontroller -> 16-bit MCU -> DSC (Digital Signal Controller) -> embedded processor. The XLP designation adds ultra-low-power sleep currents and multiple low-power operating modes (Sleep, Doze, Idle, Low-Voltage Sleep) targeted at IoT edge nodes, wearables, and remote sensors. A rich analog and digital peripheral set allows the PIC24F08KM204 to replace multi-chip analog front-ends with a single MCU. Key differentiating features include a 12-bit ADC with up to 500 ksps throughput, an 8-bit DAC, dual operational amplifiers (op amps) usable as on-chip signal conditioning stages, multiple analog comparators, and dedicated peripherals for sensor interfacing. Flexible Capture/Compare/PWM (MCCP/SCCP) modules deliver motor-control and timing capability, and the Configurable Logic Cell (CLC) provides hardware-state-machine glue logic that offloads the CPU. Communication peripherals include I2C, SPI, UART/USART with LIN and IrDA support, simplifying connection to sensors, RF transceivers, and LIN-based automotive body networks. The PIC24F08KM204 is fabricated on an advanced low-power CMOS process and operates from 1.8 V to 3.6 V. Its nanoWatt XLP technology delivers sleep currents in the nanoampere range and integrated power management with multiple oscillator sources (internal 8 MHz, 32 kHz, and PLL). The architecture provides deterministic interrupt latency, hardware DMA, and a 16 x 16-bit single-cycle multiplier that supports efficient DSP-like routines in C, easing the development of sensor-fusion and signal-processing applications at the edge. Typical applications include IoT sensor nodes, battery-powered wearables, low-power medical monitoring, automotive body-electronics (via LIN), industrial sensor transmitters, and portable consumer devices. The combination of integrated op amps, comparators, and DAC on a single die lets designers implement complete analog signal chains without external analog ICs, reducing BOM cost and PCB footprint. Designers should note that migrating between PIC24F KM-family variants primarily involves pin-count and memory-size adjustments, so code investment is portable across the family. Use Microchip's MPLAB X IDE and the free XC16 compiler for development; the PIC24F08KM204-E/MV integrates with the MPLAB Code Configurator (MCC) for rapid peripheral setup. Always consult the device-specific silicon errata document and reference the latest datasheet for silicon revision-specific behavior. This page synthesizes distributor pricing, package-level drop-in alternatives, and practical design notes not found in the manufacturer datasheet, plus comparison data against competing 16-bit MCU families to accelerate your design selection.

Its XLP design emphasizes low-power operation for compact control, sensing, and communication products. The principal features are a 32 MHz processor clock, 8 KB flash organized as 2.75K by 24 words, 2 KB of SRAM, and a broad 1.8 V to 5.5 V supply range. Integrated analog resources include a 12-bit ADC, an 8-bit DAC, and op amps, reducing the need for external components in measurements and low-power signal-conditioning circuits. Flexible capture, compare, PWM, and configurable logic-cell functions support timing, motor-control, and general embedded applications. The automotive-grade E suffix makes this ordering option suitable for extended-temperature industrial and vehicle environments when the system qualification requirements call for it. The 44-lead TQFP provides externally accessible I/O while retaining a compact surface-mount footprint. Its analog peripherals can share the same controlled supply domain as the digital logic, simplifying signal acquisition and low-level output generation. Typical applications include motor and actuator controllers, battery-powered instrumentation, industrial sensor nodes, automotive monitoring modules, compact power-conversion controllers, and low-power IoT equipment. The 2 KB RAM limits complex buffering, so applications requiring large sample histories or graphics should plan external memory or a higher-capacity MCU family. Design with the 1.8 V to 5.5 V operating range as the central power-budget constraint. Keep analog inputs within the electrical limits defined by the manufacturer datasheet, provide the required bypass capacitors close to the supply pins, and isolate noisy switching or motor-return paths from precision analog routing. This page organizes the verified device identity, electrical characteristics, package constraints, application guidance, and verified replacement information. It also identifies where pin assignments, timing limits, qualification details, and pricing must be confirmed in the manufacturer documentation or through the XAIPART Request a Quote form.

The Microchip Technology PIC24F08KM204-I/ML is a 16-bit PIC microcontroller from the PIC® XLP™ 24F family, featuring 8KB (2.75K x 24) of Flash program memory, 2KB SRAM, and 512 bytes of EEPROM, operating at 32 MHz in a 44-pin QFN (8x8 mm) package with exposed pad. It is engineered for low-power eXtreme Low Power (XLP) applications from 1.8V to 5.5V operation and integrates a rich analog peripheral set including a 12-bit ADC, dual 8-bit DACs, and operational amplifiers. A PIC microcontroller (Peripheral Interface Controller) is a class of microcontroller built on a Harvard architecture with separate program and data buses, well-suited for embedded control where deterministic interrupt response and low power consumption are essential. Within the broader taxonomy, this part sits as: 16-bit MCU -> PIC24 -> dsPIC/PIC24F family -> Microchip 8/16-bit MCU portfolio -> microcontroller -> embedded IC. XLP technology further categorizes this part within Microchip's nanoWatt XLP lineup targeting battery-powered and energy-harvesting designs where sleep current is critical. Key features of the PIC24F08KM204-I/ML include: integrated 12-bit A/D converter with up to 16 input channels, dual 8-bit Digital-to-Analog converters for bias generation, operational amplifiers for signal conditioning, configurable logic cells (CLC) for hardware state-machine implementation, multiple Capture/Compare/PWM (CCP) modules for motor or lighting control, and a 16-bit PIC24F core executing at up to 32 MIPS (million instructions per second). The device also offers UART, SPI, and I2C serial interfaces for inter-MCU communication, plus a real-time clock and calendar (RTCC) module with calendar alarm support. Architecturally, the PIC24F08KM204 employs a 16-bit modified Harvard core with single-cycle hardware multiply and divide, a 16-element working register array, and a 24-bit instruction word optimized for C code density. The integrated op amps and DACs power the silicon to function as a mixed-signal front-end, reducing external analog circuitry in sensor-conditioning applications. XLP nanoWatt technology delivers typical sleep currents in the microampere range, with multiple deep-sleep modes that retain RAM but halt the core, ideal for battery-powered sensor endpoints. Typical applications include IoT sensor nodes with on-chip analog signal conditioning, low-power wireless sensor networks, battery-powered medical monitoring devices such as glucose meters or pulse oximeters, consumer products requiring touch/proximity sensing, industrial process transmitters with 4-20 mA loop output, and remote controls or human-interface devices. The wide 1.8V to 5.5V operating range also enables direct connection to single-cell Li-ion, two-cell alkaline, or USB-powered rails. When designing with this device, pay attention to the exposed thermal pad (EP) layout for proper heat dissipation, place 0.1 µF and 1 µF decoupling capacitors close to each power pin, and configure the unused pins as outputs low to minimize current leakage. The 44-QFN package requires careful PCB land pattern design with adequate via stitching under the EP for thermal and electrical performance.

PIC24F08KM204-I/MV

PIC24F08KM204-I/MV - 16-bit XLP MCU 32MHz 8KB Flash 48-UQFN | Microchip

The Microchip Technology PIC24F08KM204-I/MV is a 16-bit PIC24F eXtreme Low Power (XLP) microcontroller that integrates rich analog peripherals on-chip, packaged in a compact 48-pin UQFN (MV) 6x6 mm body. The device combines a 32 MHz MIPS16e CPU core with 8 KB of Flash program memory, 2 KB of SRAM and 512 B of EEPROM, and operates across a 1.8 V to 5.5 V supply range that supports both 3.3 V and 5 V system rails. According to the Microchip product page, this part is built for low-power, mixed-signal embedded designs that need A/D, D/A, comparators and op-amps in a small footprint. A microcontroller (MCU) is a single-chip computer that integrates a processor, memory and programmable I/O. The PIC24F sub-family extends 8-bit PIC heritage to 16-bit, offering higher throughput, more deterministic interrupt latency and richer analog integration than baseline MCUs. Within Microchip's portfolio, PIC24F KM devices sit in the XLP "KM" tier that has been integrated with the Power Management > Voltage Regulators class of analog-rich, low-power MCUs used in sensor interfaces, e-metering, industrial control and battery-powered products. Key features include a 12-bit A/D converter (ADC), an 8-bit digital-to-analog converter (DAC), up to three on-chip operational amplifiers, multiple comparators with configurable logic, MCCP/SCCP capture/compare/PWM modules, and configurable logic cells (CLC) for hardware glue. The XLP architecture delivers deep-sleep currents on the order of a few hundred nanoamps in sleep with RTCC running, enabling years of battery life on a single coin cell. The UQFN-48 6x6 mm footprint exposes 36 + 20 = 56 I/Os (only a subset available on this device), four timer modules, two I2C, two SPI and two UART interfaces. Architecturally, PIC24F KM devices use a modified Harvard bus with a 16-bit instruction word and 24-bit addressing, allowing the Flash array to be mapped by the dev1" notation 2.75K x 24" found in FMC products. A peripheral switch selects among RTCC, ADC and comparator triggers for autonomous operation in sleep, offloading housekeeping from the CPU. Combined with CLC hardware, the chip can wake on analog thresholds without CPU intervention, which materially reduces average power in duty-cycled sensor designs. Typical applications include sensor signal conditioning with on-chip op-amps, low-power battery-powered instrumentation, smart sensor nodes, IoT end devices, consumer white goods user interfaces, and industrial process controllers. Designers choose this MCU when they need integrated analog, deterministic 16-bit performance and sub-microamp sleep currents without paying for a Cortex-M class core. One key design consideration is that the analog peripherals share internal reference and bias pins that must be properly decoupled; misuse of the 5 V tolerance on digital I/O near sensitive analog inputs can degrade ADC effective number of bits (ENOB). Always follow the datasheet's analog layout guidance and reference decoupling.

The Microchip Technology PIC24F16KA101-E/MQ is a 16-bit PIC XLP flash microcontroller with 32 MHz maximum speed, 16 KB of program memory, 1.5 KB of RAM, and 18 I/O pins in a 20-VQFN exposed-pad package. It is designed for power-constrained and battery-powered equipment, with low-power sleep features including deep-sleep DSBOR, DSWDT, and RTCC capabilities. A microcontroller is a programmable control component that integrates a processor core, memory, and peripherals on one semiconductor die. The PIC24F16KA101 belongs to the PIC24F family of 16-bit RISC microcontrollers, which combine digital control, communications, timing, and analog-conversion functions in compact embedded devices. Its XLP, or eXtreme Low Power, architecture is intended for systems where standby energy use is as important as active processing performance. Key features include 16 KB of flash program memory organized as 5.5K x 24 words, 1.5K x 8 RAM, 18 general-purpose I/O pins, and operation up to 32 MHz. The verified product listings also identify internal oscillators, 512 bytes of EEPROM, and serial peripherals including I2C, SPI, and UART/USART. The -E/MQ ordering code corresponds to the 20-pin VQFN exposed-pad package with tube packaging as listed by the distributor source. The PIC24F16KA101-E/MQ combines a 16-bit architecture with the XLP feature set for embedded control rather than high-throughput application processing. Flash memory supports in-system firmware updates, while the exposed thermal pad improves heat transfer from the device to the PCB. This combination is useful where compactness, low standby current, and mixed analog/digital control are more important than a large software ecosystem. Typical applications include battery-operated sensors, compact industrial monitors, low-power sensing nodes, portable measurement instruments, and embedded appliances. The internal oscillator allows a design to avoid an external crystal where timing tolerance permits, while I2C, SPI, UART/USART, PWM, and A/D converter resources support sensor acquisition, local communication, and actuator control. Designers should confirm the exposed-pad land pattern and connect the thermal pad to the appropriate ground plane. Decoupling capacitors should be placed close to the supply pins, programming and debug interfaces should follow the device programming guidance, and unused inputs should be handled to prevent unintended current consumption in low-power states.

These features make it suitable for embedded control, battery-operated instrumentation, low-power sensing, and compact consumer equipment where a 16-bit architecture and integrated Flash memory are useful. The 32MHz operating speed supports timely execution of control logic and peripheral servicing, while the 18 I/O pins provide connections for sensors, indicators, actuators, and external interfaces. XLP power-management functions help systems spend more time in low-power states, although final battery life depends on the application’s wake frequency, active peripherals, supply voltage, and firmware configuration. The internal oscillator can reduce external clock-component requirements. The /P ordering suffix corresponds to the 20-pin DIP package in verified distributor results. In contrast, /SO denotes a 20-pin SOIC package, /MQ denotes a 20-pin QFN package, and /I/P denotes an industrial-temperature variant. Engineers should therefore check the full suffix rather than treating every PIC24F16KA101 package option as mechanically interchangeable. For design implementation, verify the exact package pinout, oscillator settings, peripheral availability, and programming configuration in the Microchip datasheet before layout. Use the device’s low-power modes only after validating wake-up sources and timing in hardware. The verified data does not provide detailed electrical limits, EEPROM capacity, supply voltage, or operating-temperature limits for this exact suffix, so those values must be confirmed from the manufacturer documentation. This page combines the verified Microchip product description, distributor specifications, package information, and low-power feature details to support component identification and engineering comparison. It distinguishes the exact /P ordering code from other package and temperature variants while keeping unverified technical values explicitly marked for further review.

It integrates 16 KB of Flash program memory (5.5K x 24), 1.5 KB of RAM, and 512 bytes of EEPROM in a 20-pin SSOP package rated for the -40C to +125C extended industrial temperature range. A 16-bit microcontroller (MCU) is a programmable processor that executes instructions on 16-bit data paths, offering higher code density and arithmetic precision than 8-bit parts while remaining simpler than 32-bit ARM Cortex-M devices. Within the broader taxonomy, this PIC24F belongs to the PIC24 MCU family, then to 16-bit microcontrollers, then to microcontrollers, then to embedded processors, and finally to integrated circuits. It is purpose-built for power-constrained and battery-powered designs where the XLP feature set (DSBOR, DSWDT, deep sleep, RTCC) extends battery life into the multi-year range. Key specifications include a 32 MHz maximum operating frequency, 18 user I/O pins, a 10-bit ADC with multiple channels, and integrated peripherals such as comparators, UART/SPI/I2C, and a Real-Time Clock Calendar. The device operates from 1.8V to 3.6V and is qualified to the -E (extended) temperature grade. The 20-SSOP package provides a compact footprint well suited to space-constrained consumer and industrial modules. Architecture-wise, the PIC24F core uses a 16-bit modified Harvard architecture with a wide 24-bit instruction word, enabling efficient C compilation through DecodeOne. XLP technology incorporates a deep sleep mode with sub-microamp current draw, an ultra-low-power watchdog timer, and a power-saving RTCC that can wake the part periodically - critical for energy-harvesting and primary-cell applications. Typical applications include battery-powered sensor nodes, portable medical and wellness devices, remote controls, energy-harvesting wireless transmitters, low-power IoT end nodes, and industrial data loggers. The combination of wide operating voltage (1.8V-3.6V) and extended temperature range also suits automotive under-hood and outdoor installations. When designing with this part, ensure decoupling capacitors are placed within 5 mm of the VDDCORE and VDD pins and that unused I/O are configured as outputs to minimize current draw. The XLP sleep mode requires the RTCC, DSWDT, or an external interrupt to be the wake-up source; relying on a busy-loop delay will defeat the nanoWatt current target.

The Microchip Technology PIC24F16KA101-I/MQ is a 16-bit PIC® microcontroller from the PIC24F XLP family featuring eXtreme Low Power technology, 16KB Flash program memory, 2KB RAM, 512B EEPROM, 32MHz (16 MIPS) performance, and a 20-pin VQFN (5x5 mm) package with exposed pad. It targets power-constrained and battery-powered embedded applications where energy budget dominates the design. What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. Within the taxonomy: microcontroller -> embedded processor -> semiconductor. The "16-bit" in PIC24F refers to the modified-Harvard architecture's data path width; the "F" denotes Flash program memory; and XLP (eXtreme Low Power) is Microchip's branding for ultra-low-power modes targeting nanoWatt-class sleep currents. Key features include up to 16 MIPS performance at 32MHz, nanoWatt XLP technology with deep-sleep currents measured in nanoamps, an integrated Real-Time Clock and Calendar (RTCC) that operates from an external 32.768kHz crystal, dedicated deep-sleep brown-out reset (DSBOR) and deep-sleep watchdog timer (DSWDT) peripherals, 16 general-purpose I/O, multiple serial interfaces, and analog peripherals including a 10-bit ADC. Operating voltage ranges from 1.8V to 3.6V. The PIC24F16KA101 uses a modified-Harvard architecture with a 16-bit data word and 24-bit instruction word, balancing code density against data throughput. Its rich peripheral set is tied to the deep-sleep power domain so that timers and analog references can wake the core from nanoamp-class sleep without external circuitry - a defining characteristic of the XLP family. Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, energy-harvesting devices, low-power wireless sensor networks, and industrial data loggers. The combination of RTCC, deep-sleep peripherals, and wide operating voltage makes it a frequent choice for designs that must run for years on a single coin cell. When designing with this part, prioritize minimizing active-mode duty cycle: short computation bursts followed by deep-sleep yields the lowest energy per task. The exposed pad on the VQFN-20 must be soldered to the PCB ground plane to meet thermal and electrical specifications.

It operates at up to 32 MHz delivering 16 MIPS throughput from a 1.8V to 3.6V supply and provides 16 GPIO lines for digital I/O. A 16-bit microcontroller (MCU) is a microprocessor that processes data and instructions in 16-bit chunks, giving it a higher instruction throughput, larger addressing range, and richer peripheral integration than legacy 8-bit devices while retaining single-chip simplicity. Within the broader taxonomy, this part sits at: 16-bit MCU -> PIC24F family -> XLP (eXtreme Low Power) microcontrollers -> embedded microcontrollers -> semiconductor ICs. The PIC24F KA family is purpose-built for battery-powered and energy-harvesting designs, adding deep-sleep retention, deep-sleep brown-out reset (DSBOR), deep-sleep watchdog timer (DSWDT), and a real-time clock calendar (RTCC) that keep current draw in the nanoamp range while state and time-of-day are preserved.

Peripherals are orchestrated by a peripheral pin-select (PPS) engine that maps digital functions onto most I/O, simplifying PCB routing. Architecturally the device uses a modified Harvard RISC core with a 24-bit instruction word, single-cycle hardware multiply, and a 16-element x 16-bit working register array. The XLP power-management block supports Sleep, Idle, Deep-Sleep, and Deep-Sleep-with-RTCC modes, with typical Deep-Sleep currents in the tens of nanoamps, which is the technical reason this family dominates in coin-cell and energy-harvesting applications. Typical applications include battery-powered IoT sensor nodes, wearable health and fitness devices, remote controls, low-power wireless sensor transmitters, energy-harvesting switches, industrial data loggers, and any portable or unattended product where quiescent current budgets are measured in microamps. Designers targeting ULPMark scores, ENERGY STAR standby limits, or coin-cell lifetimes of multiple years will find the KA-series XLP feature set directly aligned with their targets. When designing with this part, allocate one I/O pin for the MCLR reset, use PPS carefully to avoid peripheral map conflicts, and follow Microchip's recommended decoupling and ICSP programming layout. For absolute minimum sleep current, leave all unused pins configured as outputs driving low and disable unused peripherals via PMD registers; these two steps alone typically reduce Deep-Sleep current by 20-40 percent versus an unconfigured default.

Designers also deploy this MCU in industrial telemetry and HVAC controllers where eXtreme Low Power with deterministic 16-bit performance is required. Design consideration: because the SSOP package has moderate thermal dissipation, derate I/O source/sink current per pin (typically ≤25 mA) and observe total package dissipation when multiple I/Os switch simultaneously. Use the internal PLL only when VIN is stable, and select the low-power secondary oscillator (SOSC) for RTCC-based sleep cycles to maximize battery life.

Key features include a 16-channel 10-bit ADC, two analog comparators, four 16-bit timers, two UART, two SPI, two I2C, five CCP/SCCP modules configurable for PWM/capture/compare, real-time clock and calendar with alarm, and a charge time measurement unit (CTMU) for capacitive touch. The 32 MHz internal oscillator removes the external crystal on cost-sensitive boards, while the 28-QFN (6x6) exposed-pad package gives a typical thermal resistance of about 32 C/W for thermally constrained designs. Internally the PIC24F16KA102 uses a 16-bit modified Harvard RISC core with single-cycle multiply, hardware stack, deterministic interrupt latency and a wide (3.0 V to 3.6 V) VDD range. The integrated 16 MIPS DSP engine plus zero-overhead loop control allows sensor-fusion math and digital-filter loops in firmware without an extra DSP chip. Typical applications include battery-powered IoT nodes, wearables, e-metering, sensor hubs, remote controls, low-power wireless peripherals (sensor-side companion MCU), capacitive-touch user interfaces, and medical monitoring handhelds. Designers should evaluate sleep-mode current (deep sleep as low as tens of nA) and active current per MHz when comparing against newer Cortex-M0+ alternatives; PIC24F16KA102 is most attractive when the design needs low BOM cost, on-chip EEPROM and Microchip's MPLAB X toolchain.

Typical uses include industrial sensor nodes, connected metering equipment, compact control panels, battery-operated monitors, and low-power embedded automation. The internal oscillator may simplify board design when an external crystal is unnecessary, while the 18 available I/O support digital interfaces and discrete control functions. Actual peripheral availability and pin multiplexing remain application-specific, so the manufacturer pinout and datasheet should be checked before assigning external functions. Designers should compare the 28-pin SPDIP footprint against the final assembly method, then validate startup behavior, watchdog settings, brownout configuration, and sleep-mode current on the assembled board. The PIC24F16KA102-I/SP is supplied in a tube, which suits prototyping and manual or fixture-assisted assembly. For production quantities, packaging logistics and sourcing should be confirmed with an authorized distributor.

PIC24F16KA102-I/SS

PIC24F16KA102-I/SS - 16-bit XLP MCU 16KB Flash 28-SSOP | Microchip

The Microchip Technology PIC24F16KA102-I/SS is a 16-bit PIC microcontroller featuring nanoWatt XLP (eXtreme Low Power) technology, 16KB Flash program memory, 2KB RAM, and 512B EEPROM in a 28-pin SSOP package. The device operates from 1.8V to 3.6V with a 32MHz internal oscillator delivering up to 16 MIPS performance, targeting power-constrained and battery-powered embedded applications. The -I temperature grade supports -40C to +85C operation, suitable for industrial-grade designs. A PIC24 microcontroller is a 16-bit modified Harvard architecture MCU from Microchip's PIC24F family, sitting between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX devices in the product hierarchy. PIC24F devices use a wide 16-bit instruction set with DSP-friendly instructions, hardware multiply/divide, and a peripheral set oriented toward motor control and low-power sensing. The 'F' suffix denotes Flash program memory and 3.3V-class operation. The XLP technology adds deep-sleep current as low as 20 nA with retention, plus peripherals like DSBOR (deep-sleep brown-out reset), DSWDT (deep-sleep watchdog timer), and RTCC (real-time clock calendar) that remain active in sleep. Key features of this part include the 16KB (5.5K x 24) Flash program memory, 19 GPIO pins with remappable peripherals (PPS), 12-bit ADC with up to 9 channels, multiple UART/SPI/I2C interfaces, 5 16-bit timers, and a real-time clock calendar. The XLP deep-sleep current is typically under 20 nA with full SRAM retention, while run current at 32MHz/3.3V is around 8 mA. The 28-SSOP footprint has a thermal resistance of approximately 71 C/W and supports hand-soldering plus standard reflow profiles. The architecture uses a modified Harvard bus with separate program and data paths, a 24-bit instruction word, and a 16-bit data path. The MIPS-style instruction set executes most instructions in one cycle. Integrated peripherals like comparators, 10-bit DAC, and CTMU (Charge Time Measurement Unit) enable touch sensing and slope-compensation without external ICs. Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, wireless metering, HVAC thermostats, and energy harvesting systems where sleep current dominates battery life. The 28-SSOP package allows breadboard-friendly hand assembly while remaining suitable for automated SMT lines. The wide operating voltage also enables direct Li-ion battery connection at 3.6V maximum. When designing with this MCU, prioritize the deep-sleep current budget over active performance; the XLP features only deliver their value when peripherals are properly switched off and unused clocks are gated. Use the PPS peripheral remapping to route signals to any GPIO, simplifying PCB layout. Always confirm that the active peripherals draw less than the wake-up event cost in duty-cycled applications. This page synthesizes Microchip datasheet values, current distributor pricing, and drop-in alternatives to the 28-SSOP footprint, information typically scattered across the datasheet, parametric tables, and XAIPART cross-reference data.
