The CTMU block provides a constant-current source that, combined with ADC sampling, yields high-resolution timing for ultrasonic distance, capacitive touch, and time-of-flight applications. Typical applications include BLDC and PMSM motor controllers, small DC and stepper motor drives, fan and pump controllers, RC servo and robotic actuators, low-cost position-control systems with quadrature encoder feedback, LED lighting drivers with constant-current regulation, and capacitive touch user interfaces. The wide operating range of 3.0V to 3.6V and industrial -40C to +85C temperature grade make it suitable for both consumer appliances and industrial equipment. When designing with this part, place a 10uF bulk capacitor plus a 0.1uF decoupling capacitor adjacent to the VDD pin, keep the analog VDD/VSS traces short, and configure PPS carefully to avoid unintended peripheral pin collisions on the 20-pin package. This page synthesizes distributor pricing, drop-in PIC24F family alternatives, and PCB design guidance not found on the standalone Microchip datasheet, giving engineers a single reference for selection, procurement, and layout.

PIC24FJ32MC101-I/SO

PIC24FJ32MC101-I/SO - 16-bit 32KB Flash MCU 20-SOIC | Microchip

The Microchip Technology PIC24FJ32MC101-I/SO is a 16-bit microcontroller from the PIC24FJ32MC family, featuring 32KB of FLASH program memory and 2KB of RAM, packaged in a 20-pin SOIC (SO) wide-body 7.50mm package. It executes instructions at 16 MIPS throughput via a modified Harvard RISC architecture with an internal 32 MHz oscillator, while operating from a 3.0V to 3.6V single supply across an industrial -40C to +125C temperature range. A PIC24F microcontroller is a 16-bit reduced instruction set computing (RISC) MCU in the broader PIC24F/PIC24H family of dsPIC-style microcontrollers from Microchip Technology. Within the wider product hierarchy, PIC24F belongs to the 16-bit microcontroller class -> microcontroller -> embedded controller -> semiconductor IC. The "24F" prefix denotes the FLASH-based, low-power variant optimised for cost-sensitive motor control and general-purpose applications, while the "MC" suffix in this part designates the Motor Control sub-family with hardware MCPWM, CTMU, and PPS peripherals. Key features include a 16-channel 10-bit ADC with 500 ksps conversion rate, two UART modules, one SPI port, one I2C bus, five 16-bit timers, three analogue comparators, a Charge Time Measurement Unit (CTMU), and a Peripheral Pin Select (PPS) system that remaps digital peripherals to a wide range of I/O pins. The device integrates a 6-channel MCPWM (Motor Control PWM) module and supports up to 15 I/O pins in this 20-pin package. It also includes a configurable Watchdog Timer, brown-out reset, and an in-circuit serial programming (ICSP) interface. Architecturally the PIC24FJ32MC101 combines a 16-bit datapath with a single-cycle ALU and hardware multiply/divide, allowing deterministic interrupt response and C-compiler efficient code. The CTMU enables capacitive touch sensing and precise time measurement, while the PPS router eliminates the fixed peripheral-to-pin mapping constraint of older PIC16/PIC18 parts. An integrated 8 MHz internal RC oscillator with PLL multiplication to 32 MHz removes the need for external crystals in many designs, reducing BOM cost. Typical applications include BLDC and PMSM motor drives (low-voltage fan, pump, appliance control), small appliance and white goods motor control boards, LED lighting controllers, sensor interfaces (using CTMU for touch/proximity), and general-purpose 3.3V embedded control. Automotive infotainment auxiliary modules and consumer robotics also benefit from the wide supply and temperature ranges. The combination of small footprint, motor-control peripherals, and on-chip CTMU makes this part a frequent choice where designers need compact, single-chip motion control. Designers should note that the 3.0V to 3.6V supply range is narrow - it is incompatible with 5V systems without level shifting. Decouple VDD/VSS with at least a 100 nF ceramic capacitor placed within 5 mm of the supply pins. The analog VDD/VSS pair requires a separate clean analog ground plane, and the ADC conversion accuracy is sensitive to high-frequency digital switching near AVSS - keep switching nodes and the MCU grounds segregated to one point.

PIC24FJ32MC101T-E/SO - 16-bit Motor Control MCU, 20-SOIC | Microchip
PIC24FJ32MC101T-E/SO

PIC24FJ32MC101T-E/SO - 16-bit Motor Control MCU, 20-SOIC | Microchip

The Microchip Technology PIC24FJ32MC101T-E/SO is a 16-bit microcontroller from the PIC24F motor-control family, featuring 32 KB Flash, 2 KB RAM, and an integrated Motor Control PWM (MCPWM) peripheral with three PWM channels, in a 20-pin SOIC package rated for the automotive E temperature grade (-40C to +125C). This device belongs to the 16-bit microcontroller category (MCU -> microcontroller -> embedded processor -> semiconductor). A 16-bit MCU integrates a CPU core, program memory (Flash), data memory (SRAM), and configurable peripherals on a single die; PIC24F devices use a modified Harvard architecture running the PIC instruction set at up to 16 MIPS for motor-control tasks such as BLDC commutation and PFC. Key features include 32 KB of Flash program memory (11K x 24 words), 2 KB of SRAM, three 16-bit MCPWM channels with complementary or independent outputs, three on-chip analog comparators, a Charge Time Measurement Unit (CTMU) for capacitive touch, Peripheral Pin Select (PPS) for flexible I/O mapping, and a Real-Time Clock Calendar (RTCC) module. The 16 MIPS modified-Harvard core delivers deterministic interrupt latency that is critical for field-oriented control loops running at tens of kHz. PPS removes the fixed-pin peripheral constraint of older PIC16/PIC18 parts, and the CTMU adds cost-effective capacitive-touch sensing. Typical applications include low-cost BLDC and PMSM motor drives (fans, pumps, small appliances), DC-DC converter control loops, LED lighting controllers, capacitive-touch user interfaces, and automotive body modules that operate over the extended temperature range. When designing with this device, plan I/O assignments around the PPS mapping (each peripheral function can be assigned to one of several pins), and reserve one timer for the PWM time base. Note that the SO package has fewer I/O than the QFN variant; pin-limited applications should consider PIC24FJ32MC102. This page synthesizes distributor pricing, drop-in alternative MPNs, and practical design notes not found in the manufacturer datasheet alone, enabling faster component selection for motor-control and embedded designs.

PIC24FJ32MC102-E/ML

PIC24FJ32MC102-E/ML - 16-Bit 32KB Flash Motor Control MCU | Microchip

The Microchip Technology PIC24FJ32MC102-E/ML is a 16-bit PIC24F microcontroller from the PIC24FJ32MC1xx motor-control family, featuring 32KB of Flash program memory, 2KB of RAM, and 16 MIPS performance in a 28-pin QFN (6x6) package. It integrates dedicated motor-control peripherals including three Motor Control PWMs (MCPWM), three analog comparators, a Charge Time Measurement Unit (CTMU), Real-Time Clock/Calendar (RTCC), and Peripheral Pin Select (PPS) for flexible signal routing. A 16-bit microcontroller (MCU) is a microprocessor that processes instructions 16 bits at a time, sitting in the hierarchy between 8-bit MCUs (cost-optimized, simpler control) and 32-bit MCUs (higher performance, more complex applications). Within the broader taxonomy, the PIC24F belongs to the microcontrollers -> embedded controllers -> semiconductor category. The PIC24FJ32MC102 targets cost-sensitive BLDC, PMSM, and stepper motor control applications where the larger 16-bit data path simplifies fractional arithmetic for control loops, and the integrated motor-control peripherals eliminate the need for an external gate driver controller for small motors. Key features include 21 general-purpose I/O lines, three 16-bit timers, two UART, one SPI, one I2C, a 10-bit ADC with up to 9 channels and 500 ksps conversion rate, and an internal 8 MHz oscillator with PLL support up to 32 MHz. The CTMU enables capacitive touch sensing and precise time-of-flight measurements, while the RTCC supports calendar functions with backup power from a separate VBAT pin. The PPS module routes most digital peripherals to user-selected pins, simplifying PCB layout and BOM. Typical applications include ceiling fans, RC servo drives, small pumps, white-goods motor controllers, and low-cost BLDC/PMSM sensorless or sensored drives. Industrial uses extend to small appliance inverters and toys. Designers choose the PIC24FJ32MC102 for compact 28-pin motor-control designs that require deterministic PWM, fault protection via comparators, and field-proven PIC24F firmware libraries (motor control, USB, graphics). It is pin-compatible with the PIC24FJ16MC102 (half the Flash) and the PIC24FJ32MC104 (32-pin variants with more peripherals).
