PIC24F16KM102T-I/SO

PIC24F16KM102T-I/SO - 16-bit XLP 32MHz MCU, 16KB Flash | Microchip

The Microchip Technology PIC24F16KM102T-I/SO is a 16-bit PIC® XLP™ (eXtreme Low Power) microcontroller running at 32 MHz with 16 KB Flash, 1 KB RAM and 512 bytes of EEPROM in a 28-pin SOIC wide-body package. It belongs to the PIC24F KM1 family of nanoWatt XLP microcontrollers, delivering 16 MIPS of throughput with a 5.5 V image per pin and supporting both 3 V and 5 V applications. The 'I' suffix denotes the industrial temperature range of -40 °C to +85 °C, while the 'T' indicates tape-and-reel packaging. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of on-chip peripherals such as timers, ADC, communication interfaces and configurable logic. The PIC24F family is built around Microchip's 16-bit modified Harvard architecture, sitting in the hierarchy between 8-bit PIC MCUs and the higher-end dsPIC/PIC 32 families. The XLP designation indicates aggressive nanoWatt sleep-current design, making KM1-series parts especially well-suited to battery-powered or energy-harvesting products. Key features of the PIC24F16KM102T-I/SO include 16 KB Flash (5.5 K × 24 instruction words), 1 KB RAM and 512 bytes of EEPROM, three 16-bit Capture/Compare/PWM (MCCP/SCCP) modules, a 12-bit A/D converter with up to 10 channels, analog comparators, a Configurable Logic Cell (CLC) for hardware glue logic, and a rich set of serial peripherals including I²C, SPI and UART. The wide 1.8 V to 5.5 V operating voltage range plus a low-power sleep current in the microamp range positions this part for portable, sensor and consumer devices. The architecture combines a 16-bit data path with an 8-channel DMA, dual 16-bit timers and a flexible pin-mapping Peripheral Pin Select (PPS) block. PPS allows digital peripherals to be remapped to a wide range of I/O pins at runtime, which simplifies PCB layout and BOM reuse inside the KM1 family. The 12-bit ADC supports up to 500 ksps with hardware accumulation, and the CLC block can implement state machines, waveform generation and signal conditioning in pure hardware. Typical applications include ultra-low-power sensor nodes, battery-powered IoT endpoints, portable medical accessories, consumer human-interface devices, low-cost motor control, and general-purpose embedded control with a 3 V coin-cell or USB-derived supply. The 28-pin SOIC package also enables hand-soldering and breadboarding for prototype and hobby use. Compared with smaller 14/20-pin KM1 devices, the 28-pin variants expose more ADC channels and PWM channels, so they fit designs where more analog or timing resources are required. When designing with this part, budget for an external decoupling network of 100 nF + 10 µF within 5 mm of every VDD/VSS pair, and use the PPS block to keep high-speed signals short. The KM1 family shares its MPLAB X IDE toolchain, MCC code configurator and XC16 compiler with other PIC24F devices, easing migration if a 28-pin part becomes capacity-constrained and you move up or down the family.

PIC24F devices target portable instrumentation, sensor nodes, and consumer products requiring more peripherals and code space than 8-bit MCUs but lower cost and power than ARM Cortex-M parts. Key features of the PIC24F32KA301-I/P include six 16-bit timers, four PWM modules with independent time bases, three UART/SPI/I2C modules, up to 25 mA source/sink on I/O pins, and a Charge Time Measurement Unit (CTMU) for capacitive touch and temperature sensing. The XLP architecture achieves Deep Sleep currents down to 20 nA typical with brown-out reset and watchdog timer operational, and Run current around 190 uA/MHz at 2 V. The device uses a Harvard architecture modified-RISC CPU executing 76 instructions with three-stage pipeline. The single-cycle hardware multiplier accelerates DSP-style math, and a 32x32-bit hardware divider is shared with select peripherals. The integrated 12-bit ADC has up to 9 channels (depending on package), 100 ksps conversion rate, and automatic scan modes for sequential conversion. The CTMU produces a constant current source used for capacitive touch button and slider decoding as well as precision time measurement. Typical applications include battery-powered IoT sensor nodes, portable medical devices such as glucose meters and pulse oximeters, capacitive touch user interfaces for appliances and consumer electronics, real-time-clock-based data loggers, and low-power wireless sensor nodes interfacing to sub-GHz transceivers. The 20-pin DIP form factor is favored for breadboard prototyping, educational platforms, and industrial control retrofits where through-hole mounting is required. Design consideration - XLP parts require careful attention to wake-up latency, GPIO state retention during Deep Sleep, and peripheral library configuration. Use the MPLAB X IDE with the MPLAB XC16 compiler and MPLAB Code Configurator (MCC) for fastest bring-up. For lowest sleep current, disable unused peripherals via PMD (Peripheral Module Disable) registers and use the Deep Sleep mode with DSBOR enabled. For capacitive touch applications, the CTMU requires precise timing calibration via the ADC reference - see Microchip application note AN94. Pin-compatible SOIC variants (PIC24F32KA301-I/SO) and tape-and-reel SOIC (PIC24F32KA301T-I/SO) are available for reflow assembly.

PIC24F32KA301-I/SO - 16-bit 32MHz 32KB Flash XLP MCU | Microchip
PIC24F32KA301-I/SO

PIC24F32KA301-I/SO - 16-bit 32MHz 32KB Flash XLP MCU | Microchip

The Microchip Technology PIC24F32KA301-I/SO is a 16-bit PIC microcontroller in the PIC24F XLP family with eXtreme Low Power technology, packaged in a 20-pin SOIC (300 mil). It integrates 32KB of Flash program memory, 2KB of SRAM, and 512B of EEPROM, and runs at up to 32 MHz (16 MIPS) from a 1.8-3.6V supply. The device is designed for power-constrained and battery-powered applications and includes peripherals such as a 12-bit ADC, CTMU (Charge Time Measurement Unit), DSBOR, DSWDT, and a Real-Time Clock/Calendar that continues to operate in Deep Sleep mode. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), non-volatile data storage (EEPROM), and a rich set of peripherals (ADC, timers, communication controllers) into one package. The PIC24F belongs to the modified Harvard RISC architecture family from Microchip and sits between 8-bit PIC16/PIC18 devices and the more powerful dsPIC33/PIC32 lines, offering 16-bit data paths, single-cycle multiply, and a deterministic instruction set optimized for low-power embedded control. Key features include nanoWatt XLP technology with Deep Sleep currents drawn in the microampere range, a 12-bit A/D converter with multiple channels, multiple serial interfaces (UART, SPI, I2C), and a Charge Time Measurement Unit for capacitive touch sensing and precise time-of-flight measurements. The wide 1.8V to 3.6V VDD range supports both 3V lithium and 2x AA battery chemistries without level shifters, and the internal 8 MHz and 32 kHz oscillators reduce external component count. The 20-pin SOIC footprint offers the largest I/O count in this family while remaining hand-solderable for prototypes and low-volume production. The architecture combines a 16-bit modified Harvard RISC core with a 24-bit instruction word, 17 x 17-bit single-cycle hardware multiplier, and a 32-bit barrel shifter, delivering 16 MIPS throughput while drawing only microampere-level active current. The Deep Sleep state retains RAM and runs the RTCC, DSBOR and DSWDT, allowing wake-up intervals of seconds to months on a single coin cell. The CTMU provides a precise current source for capacitive touch and resistive sensing without an external analog front end. Typical applications include blood pressure monitors, fitness wearables, remote sensor nodes, smart thermostats, IoT endpoints, and any portable medical or industrial sensor. The combination of eXtreme Low Power, 32 KB Flash, 12-bit ADC, and CTMU makes it particularly well suited to capacitive-touch user interfaces and battery-powered measurement products. The 20-pin SOIC package allows easy hand-soldering and rework, simplifying prototyping and field-repair scenarios. When designing with this device, choose low-Iq LDO or use direct battery connection, route the analog AVdd/AVss pins with a star ground topology, and place the CTMU current-source traces away from switching nodes to preserve touch sensitivity. For longest battery life, prefer Deep Sleep over Idle and gate peripherals individually using PMD registers rather than software polling loops.

PIC24F32KA301-I/SS

PIC24F32KA301-I/SS - 16-bit XLP 32KB Flash MCU, 20-SSOP | Microchip

The Microchip Technology PIC24F32KA301-I/SS is a 16-bit microcontroller from the PIC24F XLP (eXtreme Low Power) family, integrating 32KB of Flash program memory (11K x 24 words), 2KB of RAM, and 512 bytes of EEPROM in a 20-pin SSOP package. It operates at up to 32 MHz (16 MIPS) from a 1.8V to 3.6V supply, and is positioned for power-constrained and battery-powered embedded designs where sleep-mode current is a primary constraint. Core integrated peripherals include a 12-bit ADC, a Charge Time Measurement Unit (CTMU), multiple timers, and the XLP peripheral set (DSBOR, DSWDT, RTCC) that continues to operate during Deep Sleep. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, volatile and non-volatile memory, and configurable peripherals on one die. The PIC24F family uses a 16-bit modified Harvard architecture with a 24-bit instruction word, giving higher code density than 8-bit MCUs while staying cheaper and lower-power than most 32-bit Cortex-M parts. The "F" suffix denotes Flash program memory; XLP is Microchip's branding for nanoWatt eXtreme Low Power techniques such as Deep Sleep, Sleep, Idle, and alternate clock modes. Within the power-management IC hierarchy, this MCU sits above simple voltage regulators but below application processors, providing intelligent control for sensors, displays, and low-rate RF interfaces. Key features of the PIC24F32KA301-I/SS include industry-leading Deep Sleep current (typical values in the nanoamp-to-low-microamp range), 16 MIPS throughput at 32 MHz, an integrated CTMU for capacitive touch or precise time-of-flight measurement, a 12-bit A/D converter with multiple input channels, and multiple serial interfaces (UART, SPI, I2C). The device supports on-chip debugging via two programming/debug pins and is firmware-compatible across the PIC24F K-series, allowing easy migration between pin counts and memory sizes. Typical applications include battery-powered sensor nodes, wearable health monitors, remote controls, low-power wireless sensor networks, e-paper/e-ink display controllers, and IoT edge nodes. The 20-SSOP footprint is well suited to compact handheld products where board area is at a premium. The CTMU peripheral is particularly attractive for implementing touch buttons, sliders, or proximity sensing without external analog ICs, reducing BOM cost and quiescent drain. Designers should follow Microchip's recommended decoupling practice (typically a 0.1 µF ceramic plus a bulk capacitor near VDD) and consult the device-specific datasheet for the exact Deep Sleep current at the chosen VDD and temperature. For firmware reuse and migration paths, review the PIC24F KA/KM family reference manual; this part is part of a broader pin-compatible family ranging from 20 to 48 pins.
