PIC24F08KL301-I/SS

PIC24F08KL301-I/SS - 16-bit 32MHz 8KB Flash XLP MCU | Microchip

The Microchip Technology PIC24F08KL301-I/SS is a 16-bit PIC24F microcontroller from the nanoWatt XLP family, featuring an eXtreme Low Power architecture and 8 KB of Flash program memory in a 20-pin SSOP package. It operates at up to 32 MHz, integrates 1 KB of SRAM and 256 bytes of EEPROM-like data Flash, and supports an industrial operating temperature range of -40C to +85C. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one die. The PIC24F family belongs to the 16-bit MCU category, which sits between 8-bit MCUs (PIC10/12/16/18) and 32-bit MCUs (PIC32). It is part of the broader embedded processor taxonomy that includes DSPs, application processors, and FPGAs. The 16-bit class targets cost-sensitive applications that need more computational headroom and code density than 8-bit parts but do not justify 32-bit pricing. Key features include the nanoWatt XLP deep-sleep modes with currents down in the microamp range (specific values vary by mode), an integrated MSSP peripheral supporting both I2C and SPI, a CCP/ECCP module for PWM and capture/compare, 10-bit ADC, multiple timers, and configurable I/O. The device runs from 1.8V to 3.6V across two main operating ranges (2.5V/3.3V typical) with on-chip voltage regulation, making it compatible with both 2-cell battery and 3.3V regulated rails. Architecturally, the PIC24F08KL301 uses a Harvard RISC core with a modified Harvard bus and a 16-bit wide instruction path, a 17-bit x 15-bit working register array, and a single-cycle hardware multiply. Its peripheral set is intentionally aligned with the PIC18 family to ease migration for designers upgrading from 8-bit to 16-bit performance. AEC-Q100 grade availability supports automotive deployment where 8-bit PICs are insufficient. Typical applications include low-power battery-powered sensor nodes, consumer appliances, home automation, motor control peripherals, USB/CDC bridges, smart metering, and cost-sensitive IoT endpoints where the eXtreme Low Power modes extend coin-cell battery life. The wide 1.8V-3.6V supply also supports direct operation from 2xAA/2xAAA cells without a boost regulator. When designing with this part, choose the correct oscillator mode (internal 8 MHz FRC or external crystal) early because the PLL configuration determines achievable system clock. Plan ICD/ICSP header pinout before PCB layout so that the low-pin-count debug (PGECx/PGEDx) pins remain accessible. Also reserve the analog supply rail even when ADC is unused, because the AVSS/AVDD pins must still be bonded.

A 16-bit microcontroller is an embedded computing device whose central processing unit manipulates data in 16-bit wide chunks, sitting between 8-bit MCUs (lower performance, lower cost) and 32-bit MCUs (higher performance, more complex). Within the taxonomy of programmable logic devices, 16-bit MCUs occupy the cost-sensitive mid-tier for applications that need more computational headroom than 8-bit can offer but do not justify 32-bit ARM Cortex-M complexity. The PIC24F KL family specifically targets cost-sensitive 16-bit designs with peripheral compatibility with PIC18 for easy migration. Key differentiating features of the PIC24F08KL302-E/SP include 8KB self-programmable Flash (2.75K x 24 words), 1KB SRAM, 256 bytes EEPROM, integrated 10-bit ADC with up to 12 channels, dual analog comparators, 5 CCP/PWM modules, MSSP supporting both I2C and SPI, and nanoWatt XLP technology for sub-microamp sleep currents. The E/SP suffix indicates the Extended (-40C to +125C) operating temperature grade in SPDIP-28 package. The PIC24F08KL302 architecture uses a modified Harvard RISC CPU with a 16-bit wide data path and 24-bit wide instruction word, executing most instructions in a single oscillator cycle. This allows the device to deliver 16 MIPS performance at 32 MHz while maintaining low dynamic power. The device also features brown-out detect/reset (BOR), high/low-voltage detect (HLVD), power-on reset (POR), and a watchdog timer (WDT) for robust embedded operation. Typical applications include low-power IoT sensor nodes, battery-powered remote controls, consumer appliances, cost-sensitive industrial controls, and educational/hobbyist 16-bit designs. The 28-SPDIP through-hole package simplifies breadboarding and hand-soldered repair, making it especially popular with students and prototype developers. When designing with this device, consider the 3V supply requirement: the K in the part number designates the 1.8V-3.6V VDD range, so interface with 5V logic requires level shifters. The 8KB Flash supports roughly 2,500 lines of C code via the MPLAB XC16 compiler, adequate for typical embedded state machines and protocol stacks. This page synthesizes distributor pricing, drop-in SPDIP-28 alternatives, and practical design notes not typically found in the manufacturer datasheet alone, helping procurement and engineering teams make faster, more informed decisions.

Within the broader taxonomy: microcontroller -> 16-bit MCU -> PIC24F family -> PIC24F08KLx series -> low-power (XLP) variant. This part targets cost-sensitive applications where 16-bit performance is needed without 32-bit complexity. Key features include extreme low-power operation with nanoWatt XLP sleep currents, a 32 MHz internal oscillator, 23 digital I/O pins with interrupt-on-change capability, and 12 channels of 10-bit analog-to-digital conversion at 500 ksps. The device operates from 1.8V to 3.6V with on-chip voltage regulation, supports in-circuit serial programming (ICSP) and in-circuit debugging (ICD), and offers multiple communication interfaces including I2C, SPI, and UART. The PIC24F08KL402-E/SP uses a 16-bit RISC-style core with single-cycle multiply and hardware divide, providing deterministic interrupt latency for real-time control. Its nanoWatt XLP technology enables sleep currents below 1 uA, making it suitable for battery-powered sensor nodes, wearable electronics, and remote monitoring equipment where idle power dominates total energy consumption. Typical applications include IoT sensor nodes, low-power wireless devices, portable medical instruments, consumer electronics with battery backup, industrial sensor interfaces, and home automation controllers. The wide -40C to +125C operating range also supports industrial and outdoor deployments requiring extended temperature tolerance. When designing with this part, allocate careful attention to the ICSP programming header placement to avoid interference with debug access. The MSSP peripheral requires careful I2C pull-up resistor sizing and timing-budget analysis for multi-master or long-bus configurations.

It integrates 8 KB of Flash program memory, 1 KB of SRAM, and a 512-byte data EEPROM, runs at 32 MHz CPU clock speed, and operates from a 3.0 V to 3.6 V supply. Housed in a 28-pin VQFN (6x6 mm) package with exposed thermal pad (ML suffix), this device is qualified for the industrial temperature range (-40C to +85C) and targets cost-sensitive 16-bit embedded designs that previously used PIC18 architectures. A microcontroller (MCU) is a single-chip computer containing a processor core, program and data memory, and integrated peripherals such as timers, communication interfaces and analog blocks. The PIC24F family sits at the low-power, low-cost end of Microchip's 16-bit MCU portfolio, sitting below dsPIC and PIC24EP parts in performance hierarchy. Compared with 8-bit PIC MCUs, PIC24F devices offer 16-bit data paths, higher MIPS per MHz and richer peripherals, while keeping the same MPLAB X IDE and XC16 toolchain compatibility. The KL402 sub-family further adds nanoWatt XLP sleep modes that drop current into the nanoampere range for battery-powered designs. Key features include 17 general-purpose I/O pins, a 10-bit ADC with multiple channels, two UART modules, MSSP (I2C/SPI), CCP/ECCP capture/compare/PWM peripherals, and 5 timer modules. The 10-bit ADC supports up to 12 input channels with automatic sampling. Real-time clock, hardware CRC and a charge time measurement unit (CTMU) for capacitive touch round out the on-chip peripheral set. The device also integrates a 32 kHz low-power oscillator and supports multiple low-power sleep modes including Sleep, Idle and Doze. The PIC24F08KL402 uses a modified Harvard architecture with a 16-bit datapath and 24-bit instruction word, achieving 16 MIPS at 32 MHz. The CIP (Core Independent Peripherals) concept allows peripherals to operate without CPU intervention, reducing firmware complexity and active-time power. The CTMU enables mTouch capacitive touch sensing without an external charge pump, while the MSSP peripheral supports both I2C and SPI masters/slaves, simplifying sensor and display integration. Typical applications include low-power IoT sensor nodes, consumer white goods, home automation, battery-powered handheld instruments, LED lighting control, and cost-sensitive industrial controls. The combination of XLP sleep currents under 100 nA and the 32 MHz performance makes it well suited for products that spend most of their life in sleep but wake periodically to perform measurement or communication tasks. When designing with this part, plan the layout to keep the exposed thermal pad (EP) soldered to the ground plane for mechanical strength and thermal relief. Use MPLAB X IDE with the XC16 compiler for firmware development, and consider the free MPLAB Code Configurator (MCC) plug-in to generate peripheral init code. Decouple VDD/VSS with a 100 nF ceramic capacitor close to each power pin pair as called out in the datasheet.

PIC24F08KL402-I/SP - 16-bit 32MHz MCU 8KB Flash 28-SPDIP | Microchip
PIC24F08KL402-I/SP

PIC24F08KL402-I/SP - 16-bit 32MHz MCU 8KB Flash 28-SPDIP | Microchip

The Microchip Technology PIC24F08KL402-I/SP is a 16-bit microcontroller from the PIC24F KL family featuring 8 KB of Flash program memory, 1 KB of SRAM, and 512 bytes of EEPROM, housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. 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. Key features of the PIC24F08KL402 include nanoWatt XLP technology for eXtreme Low Power consumption (deep-sleep currents in the nanoamp range), four 16-bit timers, two UART modules, one I²C/SPI MSSP, up to 25 mA source/sink per I/O, and a 10-bit 1.1 Msps ADC. The device supports In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD) via two standard pins, enabling field firmware updates and low-cost development. A wide operating range of 1.8 V to 3.6 V allows direct connection to single-cell Li-ion, two-AA, or 3.3 V regulated rails. Architecturally, the KL4 core uses a single-cycle hardware multiply, a 17-bit × 17-bit MAC for DSP-style operations, and a 16-element working register array. The MSSP block reuses the familiar PIC18 SPI/I²C controller, easing code porting. 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.

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.
