PIC24F08KL302-I/SS

PIC24F08KL302-I/SS - 32MHz 16-bit XLP MCU | Microchip

The Microchip Technology PIC24F08KL302-I/SS is a 16-bit PIC24F flash microcontroller with a 32 MHz maximum clock, 8 KB of program Flash memory, 1 KB of SRAM, and a 10-bit ADC in a 28-pin SSOP package. The -I/SS ordering identifies an industrial-temperature, SSOP-packaged variant. It is designed for cost-sensitive embedded products that need efficient 16-bit processing, mixed-signal measurement, and serial communications without requiring a high-pin-count microcontroller. A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, volatile data memory, and peripherals such as ADCs, timers, communication modules, and general-purpose I/O into one device. The PIC24F08KL302 belongs to the PIC24F family of 16-bit flash microcontrollers, a product hierarchy within embedded processors and microcontrollers. Its nanoWatt XLP technology is intended for low-power operation, while its 17 I/O ports provide connections to sensors, switches, indicators, and external interface circuits. The principal device characteristics include 8 KB of Flash, 1 KB of SRAM, 512 bytes of EEPROM, operation up to 32 MHz, and a 10-bit ADC. The integrated Master Synchronous Serial Port supports I2C and SPI, while CCP and ECCP peripherals provide configurable capture, compare, and PWM-related capabilities. These resources allow a compact design to measure an analog input, exchange data with a sensor or peripheral, control outputs, and retain configuration or calibration data without adding several discrete components. The 28-pin SSOP package provides a practical balance between pin availability and board area. A 3.3 V-class supply is central to the supplied operating information, and the industrial variant is reported for operation from -40°C to +85°C. Designers should treat the ADC, communication, and timer functions as the main architectural blocks: the ADC converts analog voltage into digital values, MSSP handles serial protocols, and the CCP/ECCP blocks support timing and output-control tasks. Typical uses include low-power sensor nodes, industrial monitoring equipment, serial data bridges, compact consumer controls, cost-sensitive peripheral controllers, and embedded products that periodically wake from a low-power state. The combination of 16-bit processing, Flash program memory, EEPROM, ADC, MSSP, and 17 I/O pins is especially useful when the board must handle both control logic and real-world analog signals while maintaining a small component count. A key design consideration is to confirm the exact pin assignments, electrical limits, and peripheral multiplexing in the manufacturer datasheet before laying out the PCB. Decoupling should be placed close to the supply pins, and unused I/O pins should be handled according to the device guidance. Because the available verified results do not provide exact prices, lead times, complete pin names, or thermal and package drawings, those fields require confirmation rather than inference. This page consolidates the verified distributor and manufacturer information with a transparent comparison of the documented PIC24F08KL301-I/SS, PIC24F08KL301-E/SS, and PIC24F08KL300-I/SS same-family drop-in candidates, application guidance, and explicit data gaps. It distinguishes documented facts from unverified pricing, pinout, compliance, and package details so engineers can make an evidence-based sourcing decision.

Key features include run-mode currents under 350 uA/MHz at 1.8V, multiple low-power sleep modes (Doze, Idle, Sleep), and a wide industrial temperature range of -40C to +85C. The 28-QFN package is footprint-compatible across the PIC24F08KL/KA families, which enables PCB reuse between pin-compatible variants and code-compatible derivatives. Architecturally, the PIC24F08KL302 uses the PIC24 16-bit modified Harvard core with a 16-element 16-bit working register file and a 32 kHz to 32 MHz internal oscillator, eliminating the need for an external crystal in many designs. The MSSP peripheral supports both SPI and I2C master/slave, while the 5 CCP/ECCP channels handle PWM and capture/compare functions. Integrated 10-bit ADC, comparators, and a hardware RTCC reduce BOM cost and PCB area. Typical applications include consumer white goods, low-cost sensor nodes, battery-powered IoT peripherals, e-metering front ends, and small appliances. The XLP feature set also makes it suitable for always-on wearable accessories and remote-control keyfobs. Because the KL/KA series shares its peripheral set with PIC18, designs that start with PIC18 can migrate upward to PIC24 without rewriting drivers. When designing with this part, note that the QFN package requires thermal vias under the exposed pad for proper heat dissipation. Decoupling capacitance of at least 100 nF placed within 3 mm of each power pin, plus a 10 uF bulk cap, is recommended for stable XLP sleep behavior.

It operates at up to 32 MHz instruction-cycle speed, integrates a 10-bit ADC with up to 12 channels, and runs from a 1.8 V to 3.6 V supply. The /SP suffix denotes the 28-pin SPDIP industrial-temperature package rated from -40 °C to +85 °C. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O. The PIC24F uses Microchip's 16-bit modified-Harvard architecture with a 16-bit-wide instruction path and a 24-bit-wide instruction word, delivering roughly 2x to 5x the throughput of PIC18 8-bit parts at the same clock while remaining C-friendly. The KL402 sits at the entry level of the KL4 sub-family, designed as a cost-optimized migration path from PIC18 designs thanks to compatible peripherals such as MSSP (I²C/SPI), CCP/ECCP, and the same core register model.

The 10-bit successive-approximation ADC has a dedicated FRC oscillator and supports automatic Channel Scan and Buffer Mode. Internal oscillators are accurate to within ±2 % across temperature, eliminating the need for an external crystal in most designs. Typical applications for the PIC24F08KL402-I/SP include low-power IoT sensor nodes, battery-powered consumer devices, low-cost motor-control loops (small DC and stepper), home appliances, e-metering accessories, USB-to-UART bridges (when paired with an external transceiver), and industrial control user-interface panels. The 28-SPDIP package is especially favored for prototype breadboarding, hobbyist designs, and through-hole production assemblies where socketed replacement or hand rework is required. When designing with this MCU, note that the 28-SPDIP variant exposes 25 general-purpose I/O. For surface-mount or smaller-footprint designs, Microchip offers the same silicon in PIC24F08KL402-I/SS (28-SSOP), PIC24F08KL402-I/SO (28-SOIC), and PIC24F08KL402-I/ML (28-QFN) packages. The 'I' industrial temperature grade is the right choice for -40 °C to +85 °C environments; switch to the 'E' extended grade for -40 °C to +125 °C automotive or industrial high-temperature applications.

The Microchip Technology PIC24F08KL402-I/SS is a 16-bit PIC24 RISC microcontroller with a 32 MHz CPU, 8 KB of Flash program memory, 1 KB of data RAM, and a 28-pin SSOP package. The device also provides 512 bytes of EEPROM, a 10-bit ADC, and nanoWatt XLP technology for low-power operation. It is positioned for cost-sensitive embedded systems that require a compact general-purpose controller with mixed-signal and serial communications support. A PIC24 microcontroller is a general-purpose 16-bit embedded controller within the broader semiconductor and microcontroller hierarchy. Unlike an 8-bit MCU, the PIC24 architecture provides a wider register and data path suited to control loops, protocol handling, and compact sensor-processing tasks. The PIC24F08KL402 combines that core with nanoWatt XLP power-management functions, MSSP support for I2C or SPI, and CCP/ECCP peripherals for flexible timing and capture or compare functions. The verified device data identifies a 32 MHz operating frequency, 8 KB of Flash memory organized as 2.75K by 24 words, and 1 KB of data RAM. Its 10-bit ADC supports embedded analog measurement, while two comparators, six timers, and a watchdog timer broaden the on-chip control resources. MSSP peripherals support I2C and SPI connectivity, and ECCP provides additional control flexibility where the application requires more dedicated capture, compare, or pulse-width resources. The PIC24F08KL402 is a CMOS device that combines power-on reset and brown-out reset protections with low-power design features. Its 512-byte EEPROM gives the firmware a nonvolatile location for calibration values, configuration data, or counters that must survive a power cycle. The industrial-temperature suffix in the ordered MPN identifies the -I/SS ordering code, while the SSOP package provides 28 leads for surface-mount assembly. Typical applications include industrial sensor nodes, compact environmental monitors, motor or actuator controllers, low-power data-acquisition modules, and connected equipment using SPI or I2C peripherals. Its 10-bit ADC supports sensor interfaces, while the timer and CCP resources suit periodic measurement, PWM generation, and timing tasks. The combination of 32 MHz processing and 1 KB of RAM is appropriate for small control loops rather than memory-intensive edge-computing workloads. Designers should verify the exact operating-voltage range, ADC performance, pin multiplexing, and timing limits in the manufacturer datasheet before layout release. Decoupling, programming, and clock considerations should follow the device's recommended hardware guidelines. Because the verified data does not provide a complete pin table, this page does not reconstruct or guess individual pin assignments. This page combines verified distributor specifications, manufacturer product information, and explicitly sourced drop-in references with practical design guidance. It distinguishes confirmed electrical and peripheral data from unavailable details, helping engineers compare the PIC24F08KL402-I/SS without introducing unsupported specifications.

PIC24F08KM101-E/P - 16-bit MCU, 8KB Flash, 32MHz | Microchip
PIC24F08KM101-E/P

PIC24F08KM101-E/P - 16-bit MCU, 8KB Flash, 32MHz | Microchip

The Microchip Technology PIC24F08KM101-E/P is a 16-bit PIC XLP 24F microcontroller with 8KB Flash, 1KB RAM, and 512B EEPROM, housed in a 20-pin PDIP package rated for the -40C to +125C industrial temperature range. The device runs at up to 32MHz core clock from a 1.8V-3.6V supply and integrates a 12-bit ADC with up to 16 input channels, dual comparators, configurable logic cells, and CCP/PWM modules. It belongs to the nanoWatt XLP family, which targets extreme low-power applications where active current and sleep current both matter. What is a PIC24F microcontroller? A PIC24F is a 16-bit RISC microcontroller in the Microchip PIC24 family, sitting between the 8-bit PIC16/PIC18 line and the 32-bit PIC32 line in Microchip's portfolio. It uses a modified Harvard architecture with a 16-bit data path, runs most instructions in one cycle, and is aimed at low-power embedded designs that need more headroom than 8-bit parts but not the full performance of a 32-bit core. PIC24F derivatives add Microchip's eXtreme Low Power (XLP) technology with deep-sleep currents below 1 uA, making them common in battery and energy-harvesting designs. The PIC24F08KM101-E/P offers three differentiating features for its class: 8KB self-programmable Flash with configurable write protection, a 12-bit ADC with integrated 1.024V bandgap reference for ratiometric measurements, and MCCP/SCCP timer modules supporting Capture, Compare, and PWM modes. Its nanoWatt XLP idle and sleep modes drop quiescent current into the microamp range, while the integrated op-amp and dual comparators let designers replace several external analog components. Real-Time Clock/Calendar hardware with separate 32kHz oscillator domain is also supported, enabling accurate time-of-day tracking without an external RTC IC. The architecture is built around a 16-bit modified Harvard core with a 3-stage pipeline, single-cycle multiply, and bit-manipulation instructions inherited from the PIC18 instruction set. Peripherals are mapped via a Peripheral Pin Select (PPS) system on PPS-capable pins, which simplifies PCB routing by remapping digital functions to alternate physical pins. The bus matrix routes 16-bit data and 24-bit instructions in parallel, giving deterministic interrupt latency critical for motor and power-control loops. Typical applications for the PIC24F08KM101-E/P include battery-powered sensor nodes, low-cost consumer appliances, industrial control panels, HVAC controllers, and small motor-control boards. Its DIP-20 package and breadboard-friendly form factor also make it a frequent choice for prototyping, hobby projects, and educational platforms. With 12-bit ADC resolution it can read thermistors, photodiodes, and strain gauges without an external signal conditioner. When designing with the PIC24F08KM101-E/P, plan the analog and digital ground topology - the device mixes a 12-bit ADC with switching I/O, and poor grounding will eat into that resolution. Use a ferrite bead or pi-filter on the analog AVdd pin to isolate ADC supply noise from digital Vdd, and add a 100nF ceramic decoupling cap within 5mm of each Vdd pin. The PPS system requires unlocking the IOLOCK register after programming, so account for that in your firmware bring-up sequence.
