Key Features
- 256 kB program Flash plus 12 kB dedicated boot Flash, with 64 kB data RAM for demanding 32-bit embedded applications
- MIPS32 M4K core running up to 50 MHz at 2.3 V to 3.6 V delivers 1.56 DMIPS/MHz for compute-intensive sensor-fusion tasks
- Charge Time Measurement Unit (CTMU) enables capacitive-touch sensing and precision analog time measurement without external analog ICs
- Real-Time Clock and Calendar (RTCC) with battery backup input maintains timekeeping independent of the main power rail
- Multiple DMA channels transfer data between peripherals and RAM at up to 50 MHz without CPU intervention, maximizing throughput
Applications
PIC32MX174F256DT-V/PT is suited for industrial HMI panels, smart metering systems, and capacitive-touch control interfaces where a 32-bit core with 256 kB Flash and integrated RTCC simplifies the bill of materials. Its CTMU peripheral enables direct touch-key and proximity-sensing designs on the same chip that runs the application logic. The 44-pin TQFP package and 2.3 V to 3.6 V supply range make it compatible with battery-powered and USB-powered embedded products requiring moderate GPIO density and DMA-accelerated serial communication.

Frequently Asked Questions
How much Flash and RAM does PIC32MX174F256DT-V/PT provide, and what does the 12 kB boot Flash add?
The device integrates 256 kB of program Flash and 64 kB of data RAM. An additional 12 kB of boot Flash stores the bootloader or a failsafe firmware image separately from the application code, allowing field firmware updates via UART or USB without risking a bricked device if power is lost during the main Flash write.
What is the CTMU peripheral on PIC32MX174F256DT-V/PT and which sensing applications does it enable?
The Charge Time Measurement Unit (CTMU) is a precision current source and time-measurement block that charges a capacitive sensor or external capacitor at a known rate of approximately 0.55 µA to 55 µA (selectable), then measures the resulting voltage with the on-chip 10-bit ADC. This enables capacitive-touch keys, sliders, and proximity detection at distances up to 20 mm without external touch-controller ICs.
At what maximum clock frequency does PIC32MX174F256DT-V/PT run, and what performance figure does that translate to?
The MIPS32 M4K core operates up to 50 MHz, delivering approximately 78 DMIPS. At 1.56 DMIPS/MHz, this performance level is sufficient for control loops running at several kHz, FFT processing on short audio frames, and Modbus or CANopen protocol stacks alongside the application firmware.
Can PIC32MX174F256DT-V/PT replace a PIC32MX154F256D in a 44-pin design, and what are the key differences?
PIC32MX174F256DT-V/PT and PIC32MX154F256D share the same 44-pin TQFP footprint and 256 kB Flash. The MX174 variant adds 3 on-chip analog comparators, CTMU, and RTCC not present on the MX154, making it a pin-compatible upgrade for designs that need touch sensing or real-time clock without adding external ICs.
What DMA capability does PIC32MX174F256DT-V/PT offer and how does it benefit high-speed SPI sensor reads?
The device includes 4 DMA channels, each capable of transferring up to 65535 bytes per trigger event at the full 50 MHz peripheral bus rate. For SPI sensor applications running at 10 MHz, DMA can burst 512 bytes from the SPI receive FIFO to RAM in approximately 51 µs without any CPU cycles, freeing the M4K core entirely for signal processing during the transfer.
