PIC24F08KL201-E/SS - 32MHz 16-bit 8KB MCU | Microchip
料号： PIC24F08KL201-E/SS ✓ 量产中PIC24F08KL201-E/SS 概述
A microcontroller is a programmable semiconductor that integrates a CPU core, nonvolatile program memory, working data memory, and peripherals into one device. The PIC24F08KL201 belongs to the PIC24F family of 16-bit microcontrollers, a higher-performance tier than 8-bit PIC MCUs. It is positioned within the broader embedded-controller and power-management ecosystem, where firmware and efficient sleep behavior reduce the energy required for battery-operated and always-on products.
Verified features include a 32 MHz clock, 8 KB Flash organized as 2.75K × 24 words, 512 bytes of RAM, a 10-bit ADC, 3.3 V operation, and an operating temperature range of -40°C to +125°C. According to the Microchip product page, the device includes nanoWatt XLP technology, an MSSP peripheral supporting I2C and SPI, and a CCP peripheral. These resources support compact control systems that require serial connectivity, timing functions, and analog measurement without relying on several separate discrete devices.
The 20-SSOP package measures 5.30 mm in width according to the verified distributor listing, making it smaller than many leaded packages while remaining compatible with conventional surface-mount assembly. The 512-byte SRAM is the principal constraint when sizing application firmware: algorithms requiring substantial working buffers may need periodic transfers to external memory or a higher-memory PIC24F variant. Flash capacity similarly favors compact control code rather than large graphical or data-logging workloads.
Typical uses include industrial sensor modules, compact motor controllers, low-power instrumentation, building controls, and cost-sensitive serial interface equipment. The MSSP can connect an I2C sensor or SPI peripheral, while the ADC supports analog process inputs and the CCP supports precise timing or capture functions. Firmware must also observe the device's operating voltage, clock configuration, pin multiplexing, and peripheral-sharing constraints.
For a new PCB, place decoupling capacitors close to the supply pins, route high-current and sensitive analog paths carefully, and confirm the exposed board requirements of the 20-SSOP footprint. For an existing PCB, verify that the alternative part uses the same 20-pin SSOP footprint, acceptable supply voltage, pin multiplexing, memory size, and peripheral arrangement before committing to a replacement.
This product synthesis consolidates verified manufacturer and distributor information, a normalized 20-pin package reference, practical application guidance, and parameter-by-parameter replacement analysis. It is intended to help engineers identify fit, compare equivalent PIC24F devices, and request current availability without concealing parameters that were not present in the supplied source data.

典型应用
PIC24F08KL201-E/SS 适用于 6 应用s: Industrial Sensor Module, Low-Power Environmental Monitor, Compact Motor Controller, Building Control and Automation Node, Battery-Powered Portable Instrument, Serial Interface and Protocol Converter.
Industrial Sensor Module
The PIC24F08KL201-E/SS fits compact industrial sensor modules that need deterministic control, analog measurement, and low-power behavior in a 20-SSOP package. Its 10-bit ADC can acquire process or sensor signals, while the 32 MHz core provides up to 16 MIPS for filtering and control logic. The MSSP supports I2C or SPI for an external sensor, transceiver, or configuration device. The -40°C to +125°C rating supports extended-temperature equipment, although the analog input range, reference accuracy, and calibration strategy must be confirmed from the manufacturer datasheet.
Low-Power Environmental Monitor
PIC24F08KL201-E/SS is suitable for battery-operated environmental monitors because nanoWatt XLP technology supports low-power operating strategies and the device operates from 3 V. The 32 MHz processor can sample sensors, apply control logic, and format results when awake, while sleep modes can reduce consumption between measurements. Its MSSP can connect an I2C temperature, humidity, pressure, or gas sensor, and the 10-bit ADC can handle additional analog inputs. Actual runtime depends on sensor current, sampling interval, and firmware-defined sleep modes.
Compact Motor Controller
The PIC24F08KL201-E/SS can serve as the control MCU in a compact motor or actuator controller where a 32 MHz 16-bit core improves timing headroom over simpler 8-bit designs. The CCP peripheral supports capture and compare functions relevant to timing or input-capture tasks, while the MSSP provides I2C or SPI communication with a driver, sensor, or host. The 8 KB Flash limit suits compact control firmware rather than elaborate motion algorithms, and the 512-byte RAM should be checked carefully against motion-control buffers.
Building Control and Automation Node
PIC24F08KL201-E/SS is appropriate for cost-sensitive building-control nodes that combine local I/O, serial sensors, and low-power operation. Its 20-SSOP package supports compact board layouts, while the MSSP can communicate with temperature, occupancy, or air-quality sensors over I2C or with SPI peripherals. The 10-bit ADC can monitor simple analog inputs, and the -40°C to +125°C grade suits extended-temperature equipment. Firmware should use the CCP peripheral for accurate timing and validate pin multiplexing before production release.
Battery-Powered Portable Instrument
PIC24F08KL201-E/SS supports portable instruments that need a 16-bit processing core and low-power operation without requiring a large package. Its 512 bytes of RAM is suitable for short acquisition buffers and local state, while the 8 KB Flash can hold a focused measurement and control application. The 10-bit ADC supports basic analog sensing, and MSSP supports digital sensors or external nonvolatile memory. Designers should compare the 512-byte RAM limit with their sampling buffer and avoid using the part for large local data logging.
Serial Interface and Protocol Converter
PIC24F08KL201-E/SS is well suited to small serial-interface products because its MSSP supports both I2C and SPI while the 32 MHz core handles framing, validation, and protocol conversion. The MCU can bridge a host serial interface to sensor, memory, or display peripherals, and the CCP peripheral may support precise timing or pulse-capture functions. Its 20-SSOP footprint helps reduce board area. Firmware and electrical review should confirm that the selected alternate peripheral mappings do not conflict with programming, oscillator, or power pins.

设计说明
Decouple the 3 V supply close to the MCU power pins using the capacitance and placement required by the manufacturer datasheet. Place the bulk capacitor near the source or regulator output and the high-frequency bypass capacitor at the device pins. Keep analog and digital return currents separated as far as practical. Because the verified data does not specify capacitor values, ESR, ripple current, or startup limits, do not select those values without consulting the official device guidance.
Confirm the exact 20-SSOP land pattern and pin numbering from the official package drawing before PCB release. Route oscillator, programming, and sensitive analog inputs away from high-current switching nodes and noisy digital clocks. The supplied source snippets do not expose the complete pin table, so validate oscillator, programming, ground, supply, and peripheral assignments against the manufacturer datasheet rather than inferring them from the SSOP outline.
Do not treat equal package dimensions as proof of drop-in compatibility. Check pin multiplexing, MSSP channel assignments, CCP functions, ADC inputs, oscillator options, memory requirements, and programming interface signals. The PIC24F08KL101 family candidates provide 256 bytes of RAM rather than the target's 512 bytes, so they can fail at runtime if firmware relies on the larger working space even when the PCB footprint matches.
Use the manufacturer power-consumption and maximum-current limits when estimating junction temperature; the supplied snippets do not provide detailed current-versus-frequency data. At 32 MHz, account for switching loss from peripherals and I/O activity rather than evaluating only active CPU current. Estimate total dissipation from the actual supply voltage and load current, then compare it with the package and board thermal limits. Any estimated thermal result should be labeled as an engineering estimate.
合规信息
The supplied manufacturer and distributor snippets do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. The device is an industrial extended-temperature microcontroller rather than an explicitly AEC-Q100-qualified automotive part.
