PIC24F08KA102-I/SO - 32MHz 16-Bit XLP MCU | Microchip
料号： PIC24F08KA102-I/SO ✓ 量产中PIC24F08KA102-I/SO 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, I/O ports, and peripherals on one chip. This device belongs to the PIC24 family of 16-bit flash microcontrollers and uses Microchip's nanoWatt XLP design approach for reduced power consumption. Its hierarchy is PIC24 microcontroller, 16-bit RISC-based MCU, embedded controller, and semiconductor. Relevant functions include general-purpose I/O, timing, communications, and power-management peripherals.
Three headline features define its capability. The 32MHz operating clock supports 16 MIPS, the 8KB Flash memory provides 2.75K words of program space, and the XLP feature set includes deep-sleep-oriented DSBOR, DSWDT, and RTCC functions. The device also includes 1KB SRAM and 512 bytes of nonvolatile EEPROM for data retention. These resources suit control products that are small, firmware-driven, and expected to spend substantial time in reduced-power states.
The PIC24 architecture combines a 16-bit instruction path with flash memory and low-power peripherals. DSBOR can support brown-out detection behavior in power-managed systems, while DSWDT provides a watchdog mechanism for recovering from firmware or operating faults. RTCC is useful when the product must retain a time reference while the main processor is inactive. The supplied records describe the MCU as PIC XLP technology intended specifically for low-consumption, battery-operated equipment.
Typical uses include battery-powered monitoring devices, compact industrial sensors, portable instruments, and embedded control modules. Its 28-pin SOIC footprint also suits conventional through-hole assembly and prototype boards where a smaller QFN package would complicate inspection or rework. A firmware designer can use the 512-byte EEPROM for calibration values or configuration data and the SRAM for working state, while the 32MHz clock provides useful processing margin for control logic.
Design planning should prioritize the device's limited 8KB program Flash and 1KB SRAM, especially when selecting an application protocol or adding a bootloader. Power-budget calculations must account for active current, timer activity, and the selected XLP mode rather than assuming the deepest sleep state consumes no energy. Decoupling, programming access, and all unused pins should be handled according to the manufacturer datasheet.
This product page combines verified manufacturer and distributor specifications, practical low-power design guidance, explicit data gaps, and a strict assessment of drop-in replacements. It distinguishes confirmed 28-pin SOIC information from package or variant references that do not establish a true pin-to-pin replacement.

典型应用
PIC24F08KA102-I/SO 适用于 6 应用s: Battery-Powered Monitoring Device, Compact Industrial Sensor Controller, Portable Measurement Instrument, Low-Power Data Logger, Battery Operated Control Module, Standalone Embedded Control Node.
Battery-Powered Monitoring Device
PIC24F08KA102-I/SO fits battery-powered monitoring equipment because its PIC XLP architecture includes DSBOR, DSWDT, and RTCC for reduced-power operation. The 32MHz, 16-MIPS processor can handle sensor sampling and local logic while the RTCC preserves a time reference without continuous CPU activity. Its 512-byte EEPROM is useful for retaining calibration or configuration values, while the 3.0V to 3.6V operating range supports common single-cell power systems. The design benefit is flexible control of duty cycling, although actual battery life must be calculated from the selected sleep mode and peripheral activity.
推荐
Compact Industrial Sensor Controller
PIC24F08KA102-I/SO is suitable for compact industrial sensors that require deterministic 16-bit control in an industrial-temperature component. The 32MHz clock and 16 MIPS throughput provide margin for sampling, filtering, threshold evaluation, and communication tasks, while the 28-pin SOIC package is convenient for conventional PCB assembly. DSWDT adds a recovery path for firmware or operating faults, and 512 bytes of EEPROM can preserve device settings across power cycles. Designers must allocate the 8KB Flash and 1KB SRAM carefully if the firmware also performs field updates.
推荐
Portable Measurement Instrument
PIC24F08KA102-I/SO can serve as the control processor in a portable measurement instrument where low energy use and local data handling are important. Its 16-bit architecture and 32MHz clock support measurement acquisition, scaling, threshold logic, and user-interface updates, while XLP peripherals allow the processor to remain inactive between samples. The 1KB SRAM accommodates working variables and the 512-byte EEPROM retains calibration constants. Compared with a continuously running system, duty-cycled operation can reduce energy use, but timer and reference currents must be included in the battery budget.
推荐
Low-Power Data Logger
PIC24F08KA102-I/SO is appropriate for a low-power data logger that periodically records information and then returns to a reduced-power state. The RTCC can maintain timing while reducing the need for continuous CPU work, and DSBOR supports controlled behavior as the supply approaches a lower operating condition. With 8KB Flash, 1KB SRAM, and 512 bytes of EEPROM, the device supports compact firmware and persistent configuration. Log-record capacity must be evaluated carefully because the confirmed Flash and SRAM are modest for large local buffers.
推荐
Battery Operated Control Module
PIC24F08KA102-I/SO can implement a small battery-operated control module that combines sensor input, local decision logic, and low-power sequencing. The 16 MIPS execution rate provides ample control-loop headroom for routine tasks at 32MHz, while the XLP peripherals enable different standby strategies. The 28-pin SOIC package exposes a practical pin count for power, programming, communications, and discrete I/O in a modest design. DSWWT should be configured deliberately so normal sleep intervals do not cause unwanted resets, and unused inputs must follow the manufacturer's guidance.
推荐
Standalone Embedded Control Node
PIC24F08KA102-I/SO works as the central controller in a standalone embedded node that must operate from a constrained 3.0V to 3.6V supply. The 16-bit core, 32MHz clock, and 16 MIPS throughput support protocol handling, state-machine logic, and peripheral coordination without an external processor. Its flash provides 2.75K program words, which is adequate for compact embedded functions, while EEPROM preserves setup values across resets. The primary engineering trade-off is limited program and data space, so protocol stacks and complex buffering should be checked against a compile-time memory budget.

设计说明
Build the power budget from the operating mode actually implemented in firmware, not only the active-current specification. Account for the 32MHz processor, timers, RTCC, DSBOR, DSWDT, communications activity, and external pull networks. Use a 3.0V to 3.6V supply design and verify the minimum voltage needed by the selected peripherals before reducing regulator headroom.
Place the required bypass capacitors adjacent to the device's supply and ground pins using the layout and component values specified in the manufacturer datasheet. The 28-pin SOIC footprint simplifies inspection, but exposed copper beneath the body should still be evaluated for thermal and assembly effects. Keep programming and debug access unobstructed so the board can be programmed and serviced without rework.
Do not select firmware or peripheral options solely from family-level descriptions. The confirmed resources are 8KB Flash, 1KB SRAM, and 512 bytes of EEPROM, so a larger protocol stack or buffering scheme may exceed memory. Likewise, confirm the exact I/O count because the supplied distributor snippets report conflicting values. Use the manufacturer pin table and electrical characteristics for the selected ordering code before schematic release.
Route sensitive analog or communication signals away from high-current switching nodes and provide a controlled ground-return path for every connected pin. Although DSWDT can recover a stuck system, an unsuitable watchdog interval may create false resets during long low-power delays. Validate watchdog, brown-out, and sleep transitions in the final power-supply and firmware configuration rather than testing them only in isolation.
合规信息
The supplied verified records confirm industrial temperature grading and active lifecycle status but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown rather than being inferred from the manufacturer or package.
